feat(postgres)!: mint tenant passwords through the credentials API
The chart generated every user's password at render time into <release>-credentials, which tenants could read again at any time and which Helm history kept for MaxHistory revisions, so a deployment whose policy requires a credential shown once could not run PostgreSQL here. The accounts move under CloudNativePG's managed roles, each pointing at the account Secret the Cozystack API seeds, so the operator creates the role with the SCRAM verifier the Secret holds and applies a changed Secret live, and a password set inside PostgreSQL is reverted. Every role is rendered as the init-script created it, because the operator reverts an attribute that differs, revokes a parent role missing from inRoles and clears a comment the spec leaves unset, while the init-script still finds the roles to drop by that comment and by membership in the marker. The init-script stops creating, passwording and altering accounts, where it would be a second writer, and keeps the two things the operator has no field for: the marker membership narrowed to a record, and createrole_self_grant. The refusal to adopt a role the chart did not mark moves into a pre-upgrade hook, because the operator adopts a managed role within seconds of the spec reaching it and the post-upgrade init-job would find it adopted already. The definition declares the credentials block, so the API seeds, serves and mints for the kind, and no longer selects the credentials Secret, which the chart no longer renders or grants. BREAKING CHANGE: PostgreSQL passwords are no longer readable from <release>-credentials. A password is issued once, by a mint on the account's Credential in core.cozystack.io, and replaced by the next mint; deleting a Postgres application whose release is suspended is refused. The conversion needs a platform variant with migrations enabled. Assisted-by: LLM Signed-off-by: Timofei Larkin <lllamnyp@gmail.com> |

feat(api): add Credential kinds and the credentials block
Cozystack generates managed application passwords at Helm render time and keeps them in a Secret tenants can read again at any time, which a deployment whose policy requires a credential shown once cannot accept. The accepted design moves generation into the API: an ApplicationDefinition declares its accounts and the stored form of a password in a credentials block, and each account gets a core.cozystack.io Credential whose mint and revoke subresources take a TokenRequest-shaped CredentialRequest. This adds the types, the built-in password formats, which the migration CLI shares so a converted release and a mint store the same form, and the account helpers that name the Secrets and read their record.

feat(backups): back up Valkey with the Redis strategy
Valkey runs on the same spotahome RedisFailover operator as Redis and speaks the same replication protocol and RDB format, so it needs no strategy kind of its own. The only difference the backup Job sees is the chart's resource-name prefix: valkey-<app> instead of redis-<app> for the sentinel Service and the auth Secret. The Redis driver now accepts applicationRef kind Valkey as well as Redis and hands the template .Release.Prefix, derived from the app's kind, which cozy-default-redis uses for every name it builds. A kind with no known prefix fails the render instead of producing an empty one. cozy-default routes apps.cozystack.io/Valkey to cozy-default-redis. A restore must target an app of the same kind as the backup's source: replaying a Redis dump into Valkey, or the reverse, is not something the strategy can promise across engine releases. The shipped template reads the prefix as `.Release.Prefix | default "redis-"`: during an upgrade the previous controller, which has no Prefix in its render context and serves only Redis, renders the new CR, and a bare reference would print "<no value>" into the names. The redis:8 image already loads RDB v11, which both shipped Valkey versions (7.2, 8.1) write. Signed-off-by: Andrey Kolkov <androndo@gmail.com> Assisted-By: LLM |

feat(bucket): add a ui flag to skip the s3manager web UI
Every bucket ships an s3manager Deployment with its Service and an Ingress or HTTPRoute on <bucket>.<tenant host>. Tenants that only use the S3 API pay for a pod per bucket and for one DNS name and TLS certificate per bucket, none of which they need. ui defaults to true, so existing buckets keep their UI. With ui set to false the bucket no longer needs the tenant apex either, since the UI hostname was its only consumer in the bucket-system chart.

feat(redis): expose min-replicas-to-write and min-replicas-max-lag
Lets an operator bound the writes lost when an isolated Redis master is failed over: the master refuses writes while fewer replicas than configured are connected and recent. Both values are unset by default, so the rendered Redis config is unchanged. Redis treats 0 in either directive as disabling the check, so the chart refuses minReplicasMaxLag 0 next to a replica requirement instead of silently turning the protection off. Negative values are refused by the schema (minimum 0), since Redis rejects them at CONFIG SET and the operator would stop healing the Sentinels of that instance. A requirement of replicas or more is refused at render: a master with replicas pods has replicas-1 replicas, so it would refuse every write for good.

feat(redis): run Sentinel on the same image as the Redis pods
The Sentinels were left on redis:6.2.6-alpine when the operator moved to the freshworks-oss fork, so that its new compiled-in default could not move them on upgrade. 6.2 is end of life, and every instance now runs a Sentinel one or two major versions behind the Redis it monitors. The rollback risk behind that pin, a newer engine rewriting dump.rdb in a format the older one cannot load, does not apply to Sentinel. It stores no RDB or AOF, only sentinel.conf on an emptyDir that the config-copy init container rewrites from the operator's ConfigMap on every start, so moving back to an older image starts from a clean config. Taking the image from the same version map as the data pods also means one image per node instead of two. The e2e comment that relied on busybox's timeout exit code in the Sentinel container is updated, since that container now carries coreutils.

feat(kubernetes-nodes): build the Proxmox worker template from the pool's Talos values (#4742)
## What this PR does
A `substrate: proxmox` pool clones its workers from a VM template the
chart never sees: capmox selects it by `proxmox.templateTags`, and the
pool's `talos.*` values reach only the installer written into the worker
machineconfig. Nothing in the repository says which image that template
has to carry, and the image an operator reaches for is the wrong one:
- The release asset `nocloud-amd64.raw.xz` is built from
`packages/core/talos/images/talos/profiles/nocloud.yaml`, the bare-metal
node image. Its `zfs` extension starts `ext-zfs-service`, which waits
for `/dev/zfs`. A VM never has it, so `startAllServices` never finishes,
and Talos fails the boot sequence and reboots the guest each time the
boot timeout runs out. On our v1.13.6 stand that was every ~70 minutes,
visible in the tenant only as `SandboxChanged` on every Pod (218 cilium
restarts in 12 days); from the Proxmox side the VM never restarts. The
same profile also follows the host nodes' Talos (v1.14.2 since

feat(redis): size the Sentinel pods separately from Redis (#4832)
## What this PR does
The Redis application renders `spec.sentinel.resources` from the same
`resources`/`resourcesPreset` pair as the Redis pods. Every instance
runs three Sentinels, so it reserves three extra copies of a Redis
replica's memory for processes that hold only their configuration and
the failover state. The dataset that drives the Redis sizing never
reaches a Sentinel.
On our Cozystack v1.6.4 staging cluster, an HA Redis on `t1.nano`
reserves 3 x 128Mi for its Sentinels. The VPA recommender
(recommendation mode only) gives an uncapped target of 16Mi for the
`sentinel` container. On a `u1.small` instance the same three Sentinels
would reserve 3 x 4Gi.
This PR adds an optional `sentinel` block with the same two keys the top
level has:
```yaml
resourcesPreset: u1.small
sentinel:
resources:
cpu: 100m
memory: 64Mi
# resourcesPreset: t1.nano
```
Resolution rules:
- `sentinel` empty (the default): the Sentinels keep the Redis sizing
(`resources` + `resourcesPreset`). Existing instances therefore render
exactly as before and an upgrade does not roll their Sentinels.
- `sentinel.resourcesPreset` set: the Sentinels use that preset.
Explicit top-level `resources` are not carried over, since they were
sized for the dataset.
- `sentinel.resources` set: it wins. Any key it leaves out is filled
from `sentinel.resourcesPreset`, which falls back to `resourcesPreset`.
- The Sentinel `WorkloadMonitor` label
`workloads.cozystack.io/resource-preset` now carries the preset the
Sentinels actually use. The Redis `WorkloadMonitor` is unchanged.
Changes:
- `values.yaml`: new `Sentinel parameters` section (`@typedef Sentinel`,
`@param {Sentinel} [sentinel]`, default `{}`), reusing the existing
`Resources` and `ResourcesPreset` types so the enum and quantity
validation is the same as the top-level pair.
- `templates/redisfailover.yaml`: computes the Sentinel preset and
resources once and uses them for `spec.sentinel.resources` and the
Sentinel `WorkloadMonitor` label.
- `README.md`: generated table rows plus a short hand-written `sentinel`
section next to `resources and resourcesPreset`.
- Generated: `values.schema.json`, `api/apps/v1alpha1/redis/types.go`
(new `Sentinel` struct, `ConfigSpec.Sentinel`),
`api/apps/v1alpha1/redis/zz_generated.deepcopy.go`,
`packages/system/redis-rd/cozyrds/redis.yaml`.
- `tests/sentinel_resources_test.yaml`: 10 helm-unittest cases covering
the rules above and an unknown preset being refused.
I chose not to change the default sizing. A smaller default (for example
a fixed small preset for Sentinel) would save more for everyone, but it
would also roll every instance's Sentinels and change what tenants are
billed for on upgrade. If maintainers prefer that, it is a one-line
follow-up on top of this change.
Testing done:
- `make generate` in `packages/apps/redis` with cozyvalues-gen v1.7.0
(the version `pre-commit.yml` installs); regenerated files committed.
- Deepcopy: `controller-gen object` v0.16.4 on `api/apps/v1alpha1` (the
last step of `hack/update-codegen.sh`), only the redis package changed;
`go build ./...` and `go vet ./redis/` pass in that module, `go mod
tidy` leaves no diff. I could not run the full root `make generate` on
my machine: code-generator v0.37.1 fails to parse the Go 1.27.1 standard
library (`math/rand/v2: method must have no type parameters`), which is
a host toolchain problem unrelated to this change. CI's `codegen-drift`
job should confirm.
- `make test` in `packages/apps/redis` (helm-unittest v1.1.2): 58
passed. With the template change reverted, 4 of the new cases fail (the
ones that set `sentinel.*`); the cases that pin today's behaviour pass
both ways.
- Rendered output with no `sentinel` block is identical to `main` (all
documents except the random-password Secret) for the defaults,
`resourcesPreset=u1.small`, and explicit `resources` (cpu 1, memory
2Gi).
Backwards compatibility: purely additive. The field is optional with an
empty default, existing instances render unchanged, and nothing rolls on
upgrade. Clients that do not know the field are unaffected.
### Screenshots
Not a UI change. The dashboard form gets a `sentinel` object from the
schema like other nested parameters (e.g. `tls`).

Trigger map walked against the diff: this adds a field to
`values.schema.json`, so `cozystack/terraform-provider-cozystack` needs
to model `sentinel.resources` / `sentinel.resourcesPreset` in its Redis
resource. I will open that issue once this PR has a number and link it
here; a draft is in `FOLLOWUP-terraform-provider-redis-sentinel.md`. The
website page for `redis` is regenerated from `README.md` by the release
bot (`redis` is in the website `APPS` list), so no manual follow-up
there. Nothing else in the map is touched.
### Release note
```release-note
feat(redis): new optional `sentinel.resources` and `sentinel.resourcesPreset` parameters size the three Sentinel pods independently of the Redis pods. When unset, Sentinels keep the Redis sizing as before, so existing instances are unchanged.
```
<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit
* **New Features**
* Added independent CPU and memory resource settings and sizing presets
for Redis Sentinel pods.
* When Sentinel-specific settings aren’t provided, Sentinel pods inherit
Redis resource settings. Unspecified Sentinel resource values can use
the Sentinel preset, which defaults to the Redis preset.
* Added configuration documentation and validation for Sentinel resource
settings.

feat(kubernetes-nodes): build the Proxmox worker template from the pool's Talos values
A proxmox pool clones its workers from a VM template the chart never sees, and nothing said which Talos image that template has to carry. The one an operator reaches for, the platform release's nocloud-amd64.raw.xz, is the bare-metal node image: its zfs extension's service waits for a /dev/zfs no VM has, the boot sequence never completes, and Talos reboots every worker each time the boot timeout runs out, about every 70 minutes on v1.13. It also follows the host nodes' Talos version, not the pool's talos.version that the installer in the worker machineconfig names. The chart's default schematic has a trap of its own: its qemu-guest-agent service waits the same way for the agent's virtio port, which Proxmox adds only to a VM with the agent enabled. hack/proxmox-talos-template.sh builds the template from the chart's talos.schematicID and talos.version in the nocloud flavour with the agent enabled, refuses a tag set another template already carries, because capmox then finds two and clones neither, and prints the templateTags that select it.

fix(postgres)!: refuse plaintext sessions on external instances (#4847)
## What this PR does CloudNativePG offers TLS on an external Postgres but does not require it. Its built-in last `pg_hba` rule is `host all all all`, which matches TLS and non-TLS connections alike, so a client outside the cluster that connects with `sslmode=disable` gets an unencrypted session. The chart's `tls.enabled` only decides whether the external hostname goes into the certificate, so it cannot prevent this. This is #4619. When `external: true`, the chart now renders `spec.postgresql.pg_hba`: ```yaml pg_hba: - hostssl all all all scram-sha-256 # md5 on PostgreSQL 13, matching CloudNativePG's default rule - host all all all reject ``` CloudNativePG puts user rules after its fixed rules (`local` peer, `streaming_replica` and pooler `cert`) and before its default `host all all all` rule, and PostgreSQL uses the first matching rule, so the two lines above make remote sessions TLS-only without touching replication or the metrics exporter. See the CloudNativePG [`pg_hba` section](https://cloudnative-pg.io/documentation/current/postgresql_conf/#the-pg_hba-section) and the [template](https://github.com/cloudnative-pg/cloudnative-pg/blob/v1.30.0/pkg/postgres/configuration.go) for v1.30.0, the operator version the platform ships. A new tri-state `tls.required` follows the same pattern as `tls.enabled`: when omitted it follows `external`, `false` opts out, `true` requires TLS on an in-cluster instance too. The issue is silent on a switch; I added one because the change is breaking and a tenant with a client that cannot do TLS needs a way back that does not mean patching the operator's resources. In-cluster clients: the pod network cannot be told apart from an external client (the external Service uses `externalTrafficPolicy: Local`, so the source IP is the client's), so the rules apply to every remote client. The chart's init job connects to `<release>-rw` with libpq's default `sslmode=prefer`, which already negotiates TLS, as do the backup and monitoring paths that run inside the pod over the Unix socket. Only clients that disable TLS explicitly are refused. In-cluster instances with `external: false` are unchanged. Changes: - `templates/_tls.tpl`: `postgres.tls.required` helper. - `templates/db.yaml`: renders `spec.postgresql.pg_hba` when required. - `values.yaml`: `tls.required`, with the generated `values.schema.json`, `README.md`, `api/apps/v1alpha1/postgresql/types.go` and `packages/system/postgres-rd/cozyrds/postgres.yaml`. The `Required` deepcopy block in `zz_generated.deepcopy.go` is controller-gen v0.16.4 output. - `README.md`: new "Refusing plaintext sessions" paragraph. - `tests/pg_hba_test.yaml`: 10 helm-unittest cases. Backwards compatibility: breaking for existing external instances whose clients connect without TLS. The rules apply on the next reconcile. They are refused until the client enables TLS or the instance sets `tls.required: false`. Testing done: - `make generate` in `packages/apps/postgres` with cozyvalues-gen v1.7.0; regenerated files committed. - `helm unittest .` in `packages/apps/postgres`: 206 passed (25 suites), 10 of them new. I did not run it against a live cluster, so the `pg_hba` ordering is taken from the operator source and docs rather than observed. ### Screenshots Not a UI change. The dashboard form gets a `tls.required` toggle from the schema. ### Downstream repositories I walked the trigger map against the diff and left every box empty so a human decides. The nearest hit is the website's managed-apps reference page for postgres, which a stable-tag bot regenerates from `README.md`; the Terraform provider's postgres schema may also want the new `tls.required` field. - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note fix(postgres)!: an external Postgres now refuses sessions that are not encrypted.

feat(kubernetes-nodes): let CDI trust a self-hosted Talos image factory (#3797)
## What this PR does Adds `talos.imageFactoryCA` to the `kubernetes-nodes` chart, so CDI can verify a Talos Image Factory served with a certificate from an internal CA. Fixes #3796. ### The gap `talos.imageFactoryURL` is documented for self-hosted factories and mirrors in air-gapped, rate-limited or flaky-egress environments. Such an endpoint is normally served by the organisation's own CA, and CDI, which trusts only its system store, refuses the import with `x509: certificate signed by unknown authority`. The DataVolume never completes and no worker joins. `DataVolume.spec.source.http.certConfigMap` exists for exactly this, but the worker DataVolume in `templates/nodegroup.yaml` renders `url` alone and no value reaches that field. ### The change One optional value on the existing `talos` group of a `KubernetesNodes` pool: ```yaml talos: imageFactoryURL: "https://factory.example.com" imageFactoryCA: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- ``` When set on an HTTP import path (the default and `osImage.factory`), the chart renders a ConfigMap `<release>-talos-factory-ca` in the release namespace and points the DataVolume's `source.http.certConfigMap` at it. A pool on `osImage.builtin` clones a golden image, builds no HTTP source and gets no ConfigMap. Empty, the default, renders nothing: `helm template` with the field unset is byte-identical to `main`, so existing pools keep their KubevirtMachineTemplate name. Setting the CA changes that name, so the pool rolls once. CDI appends the bundle to the system pool rather than replacing it (`x509.SystemCertPool()` followed by `AppendCertsFromPEM` in `pkg/importer/http-datasource.go`), so a publicly trusted endpoint keeps verifying. The PEM is taken inline rather than as a ConfigMap name because `certConfigMap` must live in the DataVolume's namespace, and the dashboard offers no way to create that object by hand. ### Fail-closed guards The value lands verbatim in a ConfigMap that anything able to read the namespace can read, so it must be complete PEM certificate blocks and nothing else, and must never carry private key material. That includes the realistic accident of `cat ca.pem key.pem` pasted into the field. The rules now live in one shared helper, `cozy-lib.tls.validateCACert`, which `cozy-lib.tls.caCertSecret` also calls instead of keeping its own copy. The regexes are unchanged; the failure message names the caller's field. ### Testing - `packages/apps/kubernetes-nodes/tests/talos_image_factory_ca_test.yaml`, 13 cases: unset renders nothing, set renders the ConfigMap and a matching `certConfigMap`, whitespace-only counts as unset, multi-certificate chains, the builtin path, and each guard on the input that trips it. - `packages/tests/cozy-lib-tests/tests/tls_validatecacert_test.yaml`, 6 cases for the shared helper, plus the existing `caCertSecret` tests updated for the new message. - `make generate` in the package: regenerated `values.schema.json`, `README.md`, `api/apps/v1alpha1/kubernetesnodes/types.go` and the `kubernetes-nodes-rd` definition are committed. Not yet exercised end to end against a live internal factory. ### Not in this PR `packages/apps/vm-disk/templates/dv.yaml` renders `source.http.url` with the same gap. Left for a follow-up if this shape is accepted. ### Screenshots Not a UI change. ### Downstream repositories - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [x] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: cozystack/terraform-provider-cozystack#31 (the field belongs to the `kubernetes_nodes` model) - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: Walked the trigger map against the diff: - **terraform-provider-cozystack**: ticked.

No package is added, renamed or removed, and the reference page is regenerated from the package `README.md`, which is regenerated and committed here. - Every other repository: no path in the trigger map is touched. ### Release note ```release-note feat(kubernetes-nodes): add `talos.imageFactoryCA` so CDI can verify a self-hosted Talos Image Factory served with a certificate from an internal CA.

fix(dashboard): small Console fixes from the #3828 triage (#3837)
## What this PR does Six small Console fixes from the #3828 triage. Each one is small and most of the code sits in `apps/console/src`, so they go together in one PR. `Fixes #3105`: sizes between 1Ki and 1Mi printed as a raw byte count. `humanizeBytes` had branches for Ti, Gi and Mi and then fell through to bytes. It now has a Ki branch with the same `toFixed(0)` as the Mi branch. The `1023B` case still holds, and the test covers 1Ki and 512Ki. `Fixes #3106`: the tenant picker showed on admin pages where the tenant changes nothing. It is now hidden on the cluster-scoped admin pages only: Capacity, Backup classes, External IPs and Modules. The rest of `/admin` mounts the same tenant-scoped pages as `/console`, and those take their namespace from the tenant context, so the picker stays there. `/admin/tenants` keeps it too, because its rows come from the picker-filtered tenant list. `Fixes #3107`: both capacity drill-downs showed one generic error, so a permission failure looked like a broken page. Both now use the `error instanceof K8sApiError && error.status === 403` check that `ClusterStorageSection` already uses, with a test for the forbidden case and one for a generic error on each page. `Fixes #3102`: an immutable leaf was not restored when the YAML edit dropped its parent object. `overlayPath` stopped as soon as the submitted body had nothing at a path segment. It now creates `{}` for the missing parent, but only when the target there is undefined or null and the original really has the leaf to restore. So a scalar or an explicit null the user put there survives. A wildcard with more path under it does not rebuild a deleted parent, since that would put back entries the user removed. The test uses foundationdb's `storage.storageClass`, which is a shipped path of this shape. `Fixes #3135`: a blocked submit did not scroll to the field that blocked it. Plain `focusOnFirstError` crashes here, because RJSF's built-in handler reads `form.elements` and this form is `tagName="div"`. So the form passes a small handler that finds the field by its generated id and scrolls it into view. The ids come from one shared definition, and the widgets that had none now carry it: the `DynamicOptionsWidget` select, which every `x-cozystack-options` field uses, and the `SourceField` controls. The nested form that `AdditionalPropertiesField` mounts per map entry continues the outer id namespace instead of restarting at `root`, so fields like `nodeGroups.*.instanceType` resolve. A map key with a dot in it, such as a mariadb user `john.doe`, resolves by trying both readings of the dotted error path. `Fixes #3108`: `cilium`, `coredns` and `verticalPodAutoscaler` have only `valuesOverride` and no `enabled`, so they rendered as plain groups next to the toggleable addons and looked like a switch that failed to appear. Setting `<addon>.enabled: true` in the YAML editor is accepted, because the schema sets no `additionalProperties`, and the API stores the field and echoes it back. Nothing reads it. The three addons are not the same case. `cilium` and `coredns` are always installed. `verticalPodAutoscaler` has no switch of its own and is installed and removed together with `addons.monitoringAgents.enabled`. The three are now marked in `values.yaml` with a new `x-cozystack-no-enable-switch` schema keyword, and the form renders them with a note that there is no enable switch and an `enabled` field in YAML does nothing. The per-addon reason goes into the schema description, which the form renders and which regenerates into the README, the Go types and the ApplicationDefinition. The generated files are regenerated with cozyvalues-gen v1.7.0, the version CI pins, and the pre-commit check passes. The console typecheck and tests pass in CI. ### Screenshots ##### Ki formatting <img width="1182" height="184" alt="image" src="https://github.com/user-attachments/assets/62662265-4f77-455d-b90e-85e417684bb9" /> ##### Admin without tenant picker <img width="1440" height="245" alt="image" src="https://github.com/user-attachments/assets/99aff4f3-fda9-4c4c-8cf8-0c1eb01fb973" /> ##### Capacity 403 error <img width="1232" height="270" alt="image" src="https://github.com/user-attachments/assets/f4e4b328-ee5e-4516-b78f-9b5084b6bbc8" /> <img width="1232" height="944" alt="image" src="https://github.com/user-attachments/assets/142e438e-f538-436e-aae8-dfb79ec747e8" /> ##### Validation focus <img width="1166" height="135" alt="image" src="https://github.com/user-attachments/assets/89abb73b-a624-406f-9736-3bf38bb8a923" /> ##### Addon lifecycle <img width="1166" height="591" alt="image" src="https://github.com/user-attachments/assets/14a95891-84d1-4073-a009-bc0eab94f114" /> ### Downstream repositories I walked the trigger map in `docs/agents/contributing.md` against the diff, file by file.

feat(kubernetes-nodes): let CDI trust a self-hosted Talos image factory
talos.imageFactoryURL is documented for self-hosted factories and mirrors in air-gapped, rate-limited or flaky-egress environments. Such an endpoint is normally served with a certificate from an internal CA, and CDI — which trusts only its system store — refuses the import with "x509: certificate signed by unknown authority". The DataVolume never completes, no worker joins, and the release sits in install until it times out. DataVolume.spec.source.http.certConfigMap exists for exactly this, but the chart rendered source.http.url alone and no value reached the field. Add an optional talos.imageFactoryCA taking the CA in PEM form. When set, the chart renders it into a ConfigMap in the release namespace — CDI requires certConfigMap to sit alongside the DataVolume — and references it from the worker DataVolume on the HTTP import path; a pool cloning a golden image via osImage.builtin builds no source.http and renders neither. When empty, nothing is rendered and the output is byte-for-byte what it was. CDI appends the bundle to the system pool rather than replacing it, so a release pulling from a publicly-trusted endpoint keeps verifying either way. The value is emitted verbatim into a ConfigMap readable by anything that can read the namespace, so the render fails closed on private key material and on anything that is not complete PEM certificate blocks. Those guards live in a new validate-only cozy-lib.tls.validateCACert helper that takes the caller's field name for its messages, and cozy-lib.tls.caCertSecret is refactored onto it, so the check exists in exactly one place.

feat(redis): size the Sentinel pods separately from Redis
Every Sentinel pod gets the Redis pods' resources, so the three Sentinels of an instance reserve three times a Redis replica's memory while holding only their configuration and the failover state. On a t1.nano instance that is 3 x 128Mi while the VPA recommender's uncapped target for a Sentinel container is 16Mi, and the waste grows with every larger preset, because the dataset that drives the Redis sizing never reaches a Sentinel. sentinel.resources and sentinel.resourcesPreset follow the convention of the top-level pair, and sentinel.resourcesPreset falls back to resourcesPreset. Explicit Redis resources are not carried over once the sentinel block sets either key, since they were sized for the dataset. An empty sentinel.resources map counts as unset, as an empty top-level resources does. An empty sentinel block keeps today's sizing, so existing instances render unchanged and an upgrade does not roll their Sentinels. The Sentinel WorkloadMonitor reports the preset the Sentinels actually use. Signed-off-by: Yasar Rahman <yasar.rehman@gmail.com> Assisted-by: LLM |

fix(postgres)!: refuse plaintext sessions on external instances
CloudNativePG offers TLS but its built-in last pg_hba rule, host all all all, also accepts plaintext, so a client outside the cluster that connects with sslmode=disable gets an unencrypted session. tls.enabled only decides whether the external hostname goes into the certificate and cannot prevent this. When external is true the chart now renders spec.postgresql.pg_hba with hostssl all all all scram-sha-256 followed by host all all all reject. CloudNativePG places user rules after its fixed rules and before its default rule, and the first match wins, so only TLS sessions are accepted. The pod network cannot be told apart from an external client, so in-cluster clients are held to the same rule; libpq's default sslmode=prefer already negotiates TLS. The new tri-state tls.required follows external when omitted. Setting it to false keeps accepting plaintext on an external instance and true requires TLS on an in-cluster one. The hostssl rule uses the same password method as CloudNativePG's own default rule (md5 before PostgreSQL 14, scram-sha-256 from 14), so existing md5 verifiers keep working on PostgreSQL 13. Rendering fails when postgresql.parameters.ssl is off while TLS is required, since hostssl would never match and every remote session would be refused. BREAKING CHANGE: external clients that connect without TLS are refused after the upgrade. Set tls.required to false to keep accepting them.

feat(gateway)!: reserve a passthrough listener's name by the spec alone (#4638)
## What this PR does This keeps the TLS-passthrough services on port 443 of the tenant Gateway and makes the passthrough rules hold on Cilium 1.20.2. It is stacked on #3343 and has to land with it (stack #4717). On 1.20, upstream Cilium marks an HTTPS-terminate listener and a TLS-passthrough listener on one port `Conflicted` when their hostnames overlap, and drops both from Envoy. That took `*.<apex>` and the `api`, `vm-exportproxy` and `cdi-uploadproxy` passthrough listeners down together on every tenant Gateway in `dns01` and `existingSecret` mode (#3912). #3343 now ships a patched operator that conflicts the pair only when the hostnames are equal, so the layout stays as it is on main: one Gateway, one address, everything on 443. What remains is the equal-hostname case and the cleanup that 1.20 allows. Under `http01`, a name a passthrough listener answers is now reserved by the spec alone. Before, the controller dropped the terminate listener for such a name only once a TLSRoute was attached to the passthrough listener and its backend Service resolved, which copied how Cilium builds filter chains. Without a working TLSRoute, an HTTPRoute on `api.<apex>` kept its terminate listener next to `tls-api`, and on 1.20 that equal-hostname pair takes both listeners down. Now such an HTTPRoute gets no listener and no certificate, TLSRoute or not. If all its hostnames are reserved it reads `Accepted=False` with `NoMatchingListenerHostname`. If it also claims a free hostname it stays `Accepted` and is served there. The backend lookup, its Service and ReferenceGrant watches and their RBAC rules are gone. Other changes: - `tlsPassthroughListeners` is accepted under `dns01` and `existingSecret`. The old refusal relied on 1.19.5 serving all ports from one Envoy listener; 1.20 splits ports whose SNI overlaps. - A TenantGateway reads `Ready=False` with reason `GatewayClassUnsupported` when its GatewayClass lists features in `status.supportedFeatures` but not `TLSRoute`, while it renders passthrough listeners. A class that lists nothing is not judged. Cilium 1.20.2 lists `TLSRoute`. - Comments, the README and one error message no longer describe Cilium 1.19.5 as the shipped release. - The gateway chart writes `tlsPassthroughServices` on the publishing tenant only, behind the same `gateway.enabled` switch and `publishing.exposedServices` filter as the platform TLSRoutes. Before, every tenant Gateway got the three passthrough listeners with nothing routed to them, and the reservation above would have taken those names from a child tenant's own HTTPRoutes. The uniform `allowedRoutes.kinds` on port 443 from #3087 stays. The Cilium bug behind it is fixed since 1.19.6, but several tests pin it, so removing it is a separate cleanup. ### Upgrade notes Only the publishing tenant keeps the `api`, `vm-exportproxy` and `cdi-uploadproxy` passthrough listeners. That is `tenant-root` unless `publishing.ingressName` says otherwise, and only for names in `publishing.exposedServices` while `gateway.enabled` is on. Other tenants lose these listeners on upgrade. Nothing shipped was attached to them, so a child tenant's own HTTPRoute on `api.<child-apex>` keeps its listener and certificate. Two narrow cases do change. On the publishing tenant under `http01`, an HTTPRoute on an exposed passthrough name loses its listener and certificate when the platform TLSRoute for that name forwards nowhere (the owning package is not installed, or its backends do not resolve). A TLSRoute attached by hand to a child tenant's `tls-*` listener loses its parent. To keep that listener, merge-patch `tlsPassthroughServices` into the tenant's `TenantGateway` after the upgrade. From then on the chart does not render the key there, and later upgrades leave the patch alone. `dns01` and `existingSecret` do not change: the wildcard listener still covers such a name, and the passthrough listener answers it by its exact name. Tested locally: Go tests for the controller, `go vet`, helm-unittest for `extra/gateway` and `cozystack-controller`, `make generate` and `make manifests` with no diff. The gateway e2e scenario checks that a child tenant renders no passthrough listener. It then declares `tls-api` and a passthrough listener on a native port on that tenant, checks that the tenant stays Ready with no route behind either, and checks the reservation against `tls-api`. Unit tests catch a regression in either change. In e2e, dropping the reservation turns the gateway suite red, and dropping the chart scoping does not, because CI never sets `gateway.enabled` (#4846). The controller was not run on a live cluster; the operator patch it depends on was, see #3343. ### Downstream repositories - [ ] No downstream repository is affected by this change - [x] [cozystack/website](https://github.com/cozystack/website) - follow-up: https://github.com/cozystack/website/issues/725 - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note feat(gateway)!: the tenant Gateway renders the api, vm-exportproxy and cdi-uploadproxy passthrough listeners only on the publishing tenant, for the names publishing.exposedServices lists while gateway.enabled is on.

feat(gateway)!: reserve a passthrough listener's name by the spec alone
The TenantGateway controller withheld the HTTPS-terminate listener for a name a passthrough listener answers only once a TLSRoute was attached there and resolved a backend, mirroring how Cilium builds its filter chains. That kept a served endpoint up on Cilium 1.19.5, but it tied every route's status to one implementation's translator and needed Service and ReferenceGrant watches to land the deferred decision. The shipped operator accepts a wildcard terminate listener beside a narrower passthrough listener on 443 and keeps conflicting every other overlap. A terminate listener for the passthrough name itself is not narrower, so on 443 the rule now protects the dataplane outright; on a native port Gateway API would serve the pair, and the rule holds as a policy that keeps a platform name with its passthrough listener. Reading it off the spec makes the outcome the same on every implementation. Under http01 an HTTPRoute claiming such a name gets no listener and no certificate whether or not a TLSRoute is attached. A route whose every hostname is reserved reads Accepted=False with NoMatchingListenerHostname; one that also claims a free hostname stays Accepted and is served there, as Gateway API accepts a route whose hostnames intersect at least one listener. dns01 and existingSecret are unchanged: their wildcard listener still covers such a name, and the passthrough listener answers it by its exact server name. The chart writes the passthrough services on the publishing tenant alone, so the names reserved by default are the ones the platform publishes there through its own TLSRoutes. The shape an upgrade changes is an HTTPRoute on such a name whose platform TLSRoute forwards nowhere, because it never attached (the package owning the service is not installed) or because none of its backends resolve: that route kept a terminate listener and now gets none. The backend resolution, its watches and the RBAC rules that served them go away. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <f@lex.la> |

feat(gateway): allow tlsPassthroughListeners under dns01 and existingSecret
The refusal existed because Cilium 1.19.5 served every Gateway port from one Envoy listener matched by SNI alone, so the "*.<apex>" terminate listener of the wildcard modes and a passthrough listener under the apex could reach each other's backend. The shipped Cilium 1.20.2 gives each port its own Envoy listener when SNI overlaps across ports, and Gateway API treats listeners on different ports as compatible, so the pair is served as declared. edge still refuses the field: it renders no TLS listener for an entry to bind to.

fix(openbao): constrain the seal values that reach the server config
The upstream chart passes the server config through tpl, and its start script replaces upper case placeholders such as HOSTNAME anywhere in the copied file. A key identifier with template delimiters would run as a template inside helm-controller, which runs as cluster-admin, and an upper case one could come out different on every pod. Both key identifiers now take lowercase alphanumerics, hyphens, dots and underscores. The Secret names become pod volume names of the form userconfig-<name>, which Kubernetes validates as DNS labels. Both name fields now take a DNS label of at most 52 characters, and the volume entries are quoted. The apps API only defaults against the generated schema, so Helm enforces these patterns when it installs or upgrades the release. A previous Secret equal to the current one mounts the same volume twice, which the API server rejects for the StatefulSet, and OpenBAO refuses to start when equal key identifiers name different key material. Both cases now fail at render. The deepcopy functions for the Seal type are regenerated as well. Assisted-by: LLM Signed-off-by: Yan Bondarenko <202671653+yankawai@users.noreply.github.com> |

feat(openbao): optional static-key auto-unseal and apiserver egress label
The OpenBAO app has no auto-unseal (#2787). Every restart of a server, after a node drain, an image bump or an OOM kill, leaves it sealed until an operator enters the Shamir key shares into each replica. In HA mode the pods also hang at start (#2793). Cozystack's allow-to-apiserver policy only admits egress from pods labelled policy.cozystack.io/allow-to-apiserver, the app never set that label, and service_registration "kubernetes" cannot reach the API server without it. A new seal value selects shamir, which stays the default, or OpenBAO's seal "static". With static the chart renders the static seal stanza into the standalone and the Raft config and mounts the key Secret named in seal.secretName through the upstream chart's server.extraVolumes. The chart never generates, stores or rotates the key, because a missed lookup would replace it and leave the data unreadable. seal.previousSecretName and seal.previousKeyId carry the n-1 key that the static seal accepts during a rotation. The server pods always carry the apiserver egress label. Changing the seal of an initialized instance is a seal migration that OpenBAO performs under bao operator unseal -migrate. The chart reads the seal in use from the config ConfigMap the previous release rendered and refuses a different seal.type unless seal.allowMigration acknowledges the migration. Moving away from static needs the old stanza kept with disabled = "true", which the chart does not render, so that direction is refused regardless. The README documents the key Secret, the rotation with the pod replacement that the OnDelete update strategy requires, and the log line that confirms the re-wrap.

fix(backups): hold a Postgres backup until the plugin rollout is over (#4674)
<!-- Thank you for making a contribution! Here are some tips for you: - Use Conventional Commits for the PR title: `type(scope): description` - Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore - Scopes are not an exhaustive list — pick the most specific scope for the change and extend the list when a genuinely new area appears. Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `kind/backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does The first BackupJob on a Postgres app whose `cnpg.io/Cluster` has never carried the barman-cloud plugin — a fresh platform-flow app, or one an in-place restore re-rendered — attaches the plugin and creates the `cnpg.io/Backup` in the same reconcile. Attaching the plugin changes the instance pod spec, so CNPG rolls every instance (`Pod rollout required: volumes: element plugins has been added`). The Backup then lands on an instance without the plugin sidecar (`requested plugin is not available: barman-cloud.cloudnative-pg.io`) or on one CNPG restarts under it (`instance manager was restarted during backup`). CNPG does not retry a failed Backup, so the BackupJob stays Running in `CNPGBackupTransientFailure` until `cnpgDefaultBackupDeadline` and fails. The first backup of each such Postgres is always lost; this was observed on a v1.6.3 cluster and reproduced against `main`. The driver now holds the Backup back until that rollout is over. Before attaching the plugin to a Cluster that has none, it records `PluginRolledOut=False` on the BackupJob, with `Ready=False` reason `WaitingForPluginRollout` for the user, and requeues; the next pass attaches the plugin. The Backup is created once CNPG reports the Cluster in its healthy phase and every instance pod (`cnpg.io/cluster`, `cnpg.io/podRole=instance`) was created after the condition and is Ready; the condition then turns True and `Ready` is cleared, as before. Recording the condition first means a lost status write leaves the plugin unattached for the next pass instead of a Cluster that looks ready while it rolls. A Cluster that already runs the plugin is not rolled by the driver and its Backup is created on the first pass, as today. The wait is bounded by the existing `cnpgDefaultBackupDeadline`, after which the BackupJob fails with the phase or pod CNPG is stuck on. Why this signal, checked against the CNPG 1.29 source and the 1.30 Cluster CRD vendored here: the Cluster status has no `observedGeneration` and its `Ready` condition is derived from `status.phase`, so right after the attach the phase still reads healthy from before until CNPG reconciles the new spec. `status.pluginStatus` does not help either, since CNPG also lists plugins referenced only from `externalClusters` there, which is exactly the state of a Cluster a restore re-rendered. A pod spec change is never applied in place (only a pending Postgres restart is), so the instances are recreated and pods newer than the attach are the ones running the sidecar. This reads pod metadata and CNPG's documented labels only, not the plugin's container or volume names, and needs no RBAC change: the controller already lists and watches pods. Tests: `TestReconcileCNPG_WaitsForPluginRolloutBeforeBackup` drives a Cluster without the plugin through the attach, a stale healthy phase over the old pod, a rolling phase over the recreated pod, and the healthy phase, and asserts no Backup exists until the last step. `TestReconcileCNPG_AttachedPluginDoesNotDelayBackup` covers a Cluster that already runs the plugin, and `TestReconcileCNPG_PluginRolloutWaitIsBounded` the deadline. With the gate disabled, the first and third fail; with only the phase checked and not the pods, the first fails at the attach pass. ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes. PRs with UI changes without screenshots will not be merged. --> Not applicable: no UI change. ### Downstream repositories <!-- Cozystack is upstream for repositories that are NOT kept in sync with it automatically, and nothing in CI compares the two sides, so a change here can break them silently. Which change forces what, and which file to touch, is the trigger map in docs/agents/contributing.md under "Downstream Repositories". Walk it before you tick anything. IF YOU ARE AN AI AGENT OR AN LLM, THIS IS PART OF THE TASK, NOT A FORM TO FILL IN: 1. Walk the trigger map against the actual diff of this PR, file by file. Do not decide from the PR title or from your memory of what you changed. 2. For every repository you tick, open the follow-up PR there and link it on the same line. A ticked box with no link claims work that does not exist, which is worse than an empty box. Search that repository for an open PR or issue covering it first, and link that instead of filing a duplicate. 3. When the follow-up is out of scope, or needs a decision that is not yours to make, open an issue in that repository instead, link that, and say so in the PR body. Do not push a speculative PR into another repository just to fill a line here. 4. Do not tick "No downstream repository is affected" to make the checklist go away.

feat(redis,postgres): certify the per-engine external hostname (#4627)
<!-- Thank you for making a contribution! Here are some tips for you: - Use Conventional Commits for the PR title: `type(scope): description` - Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore - Scopes are not an exhaustive list — pick the most specific scope for the change and extend the list when a genuinely new area appears. Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `kind/backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does Redis and postgres server certificates now carry the per-engine external name `<release>.<engine>.<apex>` (for example `redis-foo.redis.example.org`) next to the flat `<release>.<apex>` they already had. Both names appear under the same condition as before: TLS on and `external: true`, with a tenant apex present. A TLS-passthrough listener on the tenant Gateway forwards the handshake untouched, so the certificate the client checks is the engine's own. The design in #2815 routes databases by SNI under `*.redis.<apex>` and `*.postgres.<apex>`, and without the per-engine name in the SAN list a verifying client would fail the hostname check. Issuing both names now means a later move between the two hostname schemes reissues no certificate and keeps clients on the same trust anchor. This is the certificate step of #2815. Nothing renders a route yet. The SAN list changes, so an existing external TLS release gets its server certificate reissued once on upgrade, from the same CA. For redis the operator then rolls the Redis and Sentinel pods one at a time, the same way it handles a renewal. The READMEs say who can reach the new name through a passthrough listener. For postgres that is only clients using direct TLS negotiation (server 17+, `sslnegotiation=direct`), because by default a plaintext SSLRequest comes before the handshake. `redis-cli` needs `--sni`. MongoDB is not in this PR. PSMDB issues the certificate itself and its CRD has no field for extra SANs, so adding the mongos name means the chart taking over the certificate. That needs its own change. Covered by helm-unittest: the name is present with TLS and external on, and absent with external off, with TLS off, and in a tenant with no apex. ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes.

fix(dashboard, kubernetes): declare the no-enable-switch addons and harden the focus helper
Use the shared RJSF ID configuration in the focus helper, preserve quoted dotted property names, and restrict its fallback to form inputs. Add route and scalar-ancestor regression coverage for the rebased admin hierarchy and immutable overlay. Mark Kubernetes addons without their own switch explicitly in the generated schema instead of inferring the behavior from their current fields, and keep lifecycle-specific copy in each field description.

fix(dashboard, kubernetes): say which cluster addons have no enable switch
cilium, coredns and verticalPodAutoscaler carry only valuesOverride and no enabled, and the addon template keys its toggle off the presence of enabled, so all three rendered as plain groups among the toggleable addons, reading as a switch that failed to appear. That is what leads users to add <addon>.enabled: true in the YAML editor, where the schema sets no additionalProperties, so the API stores the field and echoes it back while nothing reads it. The three are not the same case, so the form must not claim they are. cilium and coredns are always installed. verticalPodAutoscaler has no switch of its own but is installed and removed together with addons.monitoringAgents.enabled, so calling it mandatory would be wrong. The fixed copy states only what holds for all three, that there is no enable switch and that an enabled field in YAML does nothing, and the per-addon reason moves into the schema description, which the form already renders and which regenerates into the README, the Go types and the ApplicationDefinition. Also types the test fixture instead of spreading it as object, which erased the props and left the file failing tsc.

feat(redis,postgres): certify the per-engine external hostname
The tenant Gateway's TLS-passthrough listeners are designed to route databases by SNI under a per-engine subdomain (*.redis.<apex>, *.postgres.<apex>), and a passthrough listener forwards the handshake untouched, so the engine's own server certificate must carry <release>.<engine>.<apex> or a verifying client fails the hostname check. The name is issued next to the existing flat <release>.<apex>, under the same TLS-and-external condition, so that a later move between the two hostname schemes reissues no certificate and leaves clients on the same trust anchor. Nothing renders a route yet; the certificate is prepared ahead of it. Adding the name changes the SAN list, so existing external TLS releases get their server certificate reissued once on upgrade, from the same CA.

feat(postgres): add per-user createRole and bypassRls attributes (#3505)
## What this PR does - Adds `users.<name>.createRole` to the postgres chart, which sets the `CREATEROLE` role attribute on a managed login user. - Adds `users.<name>.bypassRls`, which sets `BYPASSRLS` on the same user. The two attributes are needed together to provision a privileged service role, see below. - Sets `createrole_self_grant` as a role-level default alongside `createRole`, without which the attribute is granted but not usable. - Refuses `createRole` on PostgreSQL 15 and older, where it is an escalation path rather than a bounded privilege. - Makes the init job record the roles it manages in a superuser-only marker instead of trusting role comments and refuses to adopt a role it did not create once `createRole` has been used, see below. - Adds `tests/user_createrole_test.yaml`: defaults, both explicit values for each attribute, composition with `replication` and with each other, the `createrole_self_grant` set and reset paths, and the version guard on v15 and v13. Adds `tests/managed_roles_test.yaml` for the marker and the adoption checks. Today a tenant that needs to create its own roles has no way to do it through the chart, because role attributes are not inherited through role membership: granting `CREATEROLE` to the generated `<db>_admin` group role has no effect on the users that are members of it, and `<db>_admin` is `NOINHERIT` anyway. The attribute has to be set on the login user itself, which only the init script can do. The remaining option is to hand the tenant the `postgres` superuser, which also gives it `COPY ... FROM PROGRAM`, arbitrary file access and command execution inside the instance pod. These flags are the narrow version of that: the tenant manages its own roles, and the superuser stays internal. Both attributes are reconciled on every init-script run, like `replication`, so setting one back to `false` emits the `NO...` form and revokes it. ## Why `bypassRls` belongs in the same PR `CREATEROLE` on its own does not let a tenant reproduce a role layout that uses row-level security, which is the common case this feature exists for. PostgreSQL only lets a role create other roles carrying `BYPASSRLS` if it holds the attribute itself, so `CREATE ROLE service_role ... BYPASSRLS` fails with `Only roles with the BYPASSRLS attribute may create roles with the BYPASSRLS attribute`. Exposing `createRole` without `bypassRls` therefore ships a feature that stops one statement short of the goal. `bypassRls` is not gated on a PostgreSQL version, because it carries no escalation of its own: `BYPASSRLS` waives row-level security inside the tenant's own databases, and the database owner already reads every row in them. It grants no reach outside the tenant's data. ## Why `createrole_self_grant` is set with the attribute This is the non-obvious half. PostgreSQL 16 grants a `CREATEROLE` holder only `ADMIN OPTION` on the roles it creates, governed by `createrole_self_grant`, whose default is empty. `ADMIN OPTION` allows granting the role onward but not `SET ROLE` to it, and creating an object owned by another role requires `SET`. The attribute therefore looks functional -- `CREATE ROLE` succeeds -- while the very next statement a tenant writes, `CREATE SCHEMA ... AUTHORIZATION <new role>`, fails with `must be able to SET ROLE`. Every tenant granted `createRole` would hit this and have to discover the parameter, so the chart sets it as a role-level default and resets it when the attribute is withdrawn. ## Why the init job stops trusting role comments and role names The init job runs as the superuser, and it trusted two things a CREATEROLE holder controls for the roles it creates. It picked the users and roles to drop by their comment, and on PostgreSQL 16 a CREATEROLE holder may `COMMENT ON ROLE` every role it created, so it could hand the chart for deletion a role the chart never created. It also adopted any role that already existed under a declared name, so a role created under a name an administrator declares later stayed under its creator's control, for example `debezium` before `users.debezium.replication: true`, or `newdb_admin` before `databases.newdb`. Neither case can be caught from the catalog. Creating a role through an intermediate role and then dropping that role leaves the squatted role with no row in `pg_auth_members` at all, while the objects, role settings and default privileges planted in it stay. On 17.11 such a `debezium` had zero memberships, and after the chart adopted it `migrator` could still run code as `debezium` with `REPLICATION` through a function it had planted. The chart therefore keeps its own record: - Chart-managed roles are members of `cozystack:managed`, a NOLOGIN role that only the superuser can grant. On 16+ the membership is `WITH INHERIT FALSE, SET FALSE`. The name is outside the username and database charsets. The delete passes act only on these members. On its first run the chart marks every role it had commented before, when no role could yet hold CREATEROLE through it. - Once any user has held `createRole`, recorded as `cozystack.createrole_granted` on the `postgres` database (the same mechanism as `cozystack.adopted_restore`), the chart refuses to adopt an existing role it did not mark, both for users and for `<db>_admin`/`<db>_readonly`. The init job fails with the role's name, and a platform administrator must drop the role. Before that point adoption works as before, so a fresh install that declares `users.app` still adopts the role CNPG bootstraps. ## The PostgreSQL 16 floor on `createRole` The floor is a security boundary, not a cosmetic check. Before PostgreSQL 16, `CREATEROLE` allowed granting membership in any non-superuser role, so a user holding it could grant itself `pg_execute_server_program` and reach command execution on the instance, which is exactly what not exposing the superuser is meant to prevent. I verified both sides on a real cluster: on 15.15 `GRANT pg_execute_server_program TO <createrole_user>` succeeds and `COPY ... FROM PROGRAM 'id'` then returns `uid=26(postgres)`; on 16.11 and 18.1 the same grant is refused because it now requires ADMIN option on the role. PostgreSQL 16 restricted `CREATEROLE` to roles the grantee administers, which is what makes the attribute safe to expose. The guard uses the same fail-fast `SECURITY:` idiom as the blocked `postgresql.parameters` list in `templates/db.yaml`. Note that a grant obtained on PostgreSQL 15 survives a major upgrade: after moving an instance to 16.11 the user kept its membership in `pg_execute_server_program` even though new attempts were refused. Operators who exposed `CREATEROLE` out of band on an older major should audit and revoke memberships in `pg_execute_server_program`, `pg_read_server_files` and `pg_write_server_files` before relying on the floor. ## Verification The marker, adoption and `createRole` paths were rendered and run against live PostgreSQL 13, 15, 16 and 17 containers. An upgrade from the previous chart marks the roles it already managed and removes a dropped user. What happens to a dropped role's objects comes from #4574 and is covered by its tests. A fresh install adopts the CNPG `app` role in the same run that grants `createRole`. A forged comment is ignored, and squatted `debezium` and `newdb_admin` roles stop the init job with nothing granted to them. The orphaned-role pass still drops the roles of a removed database, and every re-run is clean. Reverting each part of the fix in turn fails `tests/managed_roles_test.yaml`. Beyond the chart unit tests, I replayed a real migration checklist against a live PostgreSQL 17.7 instance, connected as the managed login user and never as the superuser: creation of four roles with their attributes including `CREATEROLE` and `BYPASSRLS`, `CREATE SCHEMA ... AUTHORIZATION` landing on the requested owner, trusted extensions into a named schema, per-role and per-database `search_path`, per-role `statement_timeout` and `idle_in_transaction_session_timeout`, RLS including `FORCE ROW LEVEL SECURITY` verified end to end (a plain role sees zero rows, the `BYPASSRLS` role sees them all), and `SECURITY DEFINER` functions. All of it succeeds without the superuser. The one thing that remains out of reach is `CREATE EVENT TRIGGER`, which PostgreSQL restricts to superusers and no chart flag can change. Other attributes and the predefined roles that a managed-service admin role usually wants (`pg_monitor`, `pg_read_all_settings`, `pg_maintain`) can follow the same per-user pattern in a later PR, minus the three that grant OS access (`pg_execute_server_program`, `pg_read_server_files`, `pg_write_server_files`). ### Screenshots No UI change. ### Downstream repositories `packages/apps/postgres/values.schema.json` gains two fields, which per the trigger map reaches `cozystack/terraform-provider-cozystack`: its postgres resource carries a hand-maintained schema plus an expand/flatten pair for `users`, with no codegen from `values.schema.json`, so `createRole` and `bypassRls` will be invisible to Terraform users until they are added there by hand. I searched that repository and found no open PR or issue covering it (the only open PR is a dependabot Go module bump). I have not filed the follow-up, so I am leaving the box unticked rather than claiming work that does not exist. Happy to open the issue or the provider PR if a maintainer confirms that is the preferred route. I walked the rest of the map against the diff and found nothing else: no package is added, renamed or removed, no version enum changes, no default changes, `release.prefix` and the output Secret and Service names are untouched, and no CRD outside the regenerated `packages/system/postgres-rd/cozyrds/postgres.yaml` is affected.

## What this PR does
A guest whose interfaces are rendered by netplan ignores two things the
platform already puts on the wire for it, and this adds an opt-in
`netplanDhcp` value that supplies the cloud-init network-data making it
ask for both.
`virt-launcher` starts a DHCP server on **every** bridge-bound
interface, secondary ones included — `newDHCPConfigurator` in
`pkg/network/setup/launcher/configurator.go` gates only on `iface.Bridge
!= nil`, and `BridgeConfigGenerator.Generate` serves the address the CNI
put on the pod-side interface along with that link's MTU. The chart
renders `bridge: {}` for every network, so a VM joined to a VPC subnet
is offered its reserved address and its MTU. cloud-init's fallback
network configuration covers a single interface, so on Debian and Ubuntu
nothing ever sends a DHCPDISCOVER on the second NIC and the interface
stays inert, while AlmaLinux (NetworkManager auto-profile) and Windows
come up. That asymmetry is the tell: with no DHCP server at all, none of
the three would work.
The same DHCP server advertises the launcher pod's search domains as
option 119, and `UseDomains=` defaults to `no` in systemd-networkd, so a
netplan-managed link keeps none of them. A cluster domain under `.local`
then reaches the mDNS exclusion in resolved and every lookup answers
`REFUSED`, which is #2085. `dhcp4-overrides: use-domains: true` is
enough on its own: the domains on the wire already carry whatever
cluster domain the cluster actually uses, so nothing needs to be
hardcoded here and #2372 does not collide with this.
### This is a regression, not a missing feature
`packages/apps/virtual-machine` carried exactly this, added in

feat(redis)!: refuse external access without TLS at admission (#4639)

Redis never turns TLS on by itself, so `external: true` without `tls.enabled: true` is exactly that case. The error names the release and a remedy that works. The rule has three parts, because TLS is fixed when a Redis instance is created: the RedisFailover schema refuses a change, while the Redis API accepts one and the HelmRelease then fails. A spec's `tls.enabled` is therefore a request, not proof of what the instance runs. - On create, `external: true` needs `tls.enabled: true`. - On update, turning `external` on is refused whatever `tls.enabled` says. - While `external` stays on, `tls.enabled` cannot change. Before the first reconcile nothing else stops TLS being dropped from a release admitted as external with TLS. Withdrawing `external` in the same edit lifts the freeze, and the callers trusted by `cozystack-tenant-host-policy` are exempt, so an instance whose TLS was flipped earlier can still be unblocked. Edits to a release that was already external pass, so releases exposed in plaintext before this policy keep working. The guarantee covers the Redis app. A generic publisher such as `tcp-balancer` can still forward to a plaintext Redis, by design. This diverges from the Security section of the `external-database-exposure` proposal, which refuses only an explicit `tls.enabled: false` and covers every engine. That rule was written before redis had TLS and matches only postgres. Postgres is left out here on purpose: CloudNativePG keeps `ssl=on` and its default pg_hba accepts plaintext from any client that asks, whatever the chart's `tls.enabled` says, so an admission rule on that field closes nothing. That gap is #4619. The proposal update and a decision record are cozystack/community#91. The policy follows `cozystack-tenant-host-policy`: a ValidatingAdmissionPolicy in `cozystack-basics`, enforced inside `cozystack-api` for the aggregated kind. Its decisions are tested in Go by compiling the shipped template with the apiserver's own CEL compiler and running Redis objects through it, including the bypass sequences found in review. A structural chart test can't show what the policy admits. The redis README, the `external` field description and the threat model describe the new rule.

fix(backups): give each Postgres instance its own default WAL prefix
The default CNPG strategy archived a Postgres app under <namespace>-<name>, inside a destinationPath that is also keyed by namespace and name, and the driver fell back to the Cluster name when a strategy set no serverName. Deleting the app does not empty the bucket, so an app recreated under the same name archived its WALs and base backups into its predecessor's stream: both start on timeline 1, and a later restore of the old archive could pick the new cluster's base backup or WAL segments. barman-cloud refuses a non-empty archive only while .check-empty-wal-archive exists in PGDATA. CNPG removes that file as soon as ContinuousArchiving turns True, and with no plugin attached archive_command is a successful no-op, so the file is gone minutes after initdb, before the first BackupJob attaches the plugin. Suffix the default serverName with the application UID, in the strategy template and in the driver's fallback. The template guards the UID with `with`, so an object without one renders the previous name rather than "<no value>". A Cluster that already has the plugin keeps its serverName, so only clusters never backed up take the new prefix, and restores keep reading the source prefix from driverMetadata.

feat(postgres): add per-user createRole and bypassRls attributes
Without these, a tenant that needs to manage its own roles has no option but the postgres superuser, which also hands over filesystem access and command execution on the instance. Role attributes are not inherited through role membership, so the generated <db>_admin group role cannot carry them: they have to be set on the login user itself. users.<name>.createRole and users.<name>.bypassRls set CREATEROLE and BYPASSRLS on a managed login user. Both are reconciled on every init-script run, so setting one back to false emits the NO... form and revokes the attribute. createRole is refused on PostgreSQL 15 and older. Before PostgreSQL 16, CREATEROLE allowed granting membership in any non-superuser role, so a user holding it could grant itself pg_execute_server_program and reach command execution on the instance, which is exactly what not exposing the superuser prevents. PostgreSQL 16 restricted CREATEROLE to roles the grantee administers. bypassRls carries no such gate: BYPASSRLS only waives row-level security inside the tenant's own databases, whose owner already reads every row, so it adds no reach. The two attributes are needed together, not separately. PostgreSQL only lets a role create other roles carrying BYPASSRLS if it holds the attribute itself, so provisioning a privileged service role fails with "Only roles with the BYPASSRLS attribute may create roles with the BYPASSRLS attribute" when only createRole is granted. createRole also sets createrole_self_grant as a role-level default. PostgreSQL 16 grants a CREATEROLE holder only ADMIN OPTION on the roles it creates, governed by that parameter, whose default is empty. ADMIN OPTION allows granting the role onward but not SET ROLE to it, and creating an object owned by another role requires SET. The attribute therefore looks functional -- CREATE ROLE succeeds -- while the next statement a tenant writes, CREATE SCHEMA ... AUTHORIZATION <new role>, fails with "must be able to SET ROLE". The default is reset when the attribute is withdrawn. The init job runs as the superuser, and before this change it trusted two things a CREATEROLE holder controls for the roles it creates: role comments and role names. It picked the users and roles to drop by their comment, and a PostgreSQL 16 CREATEROLE holder may comment every role it created, then hand it to the chart for deletion. It adopted any role that already existed under a declared name, so a role created under a name an administrator declares later stayed under its creator's control. Neither can be caught from the catalog: creating a role through an intermediate role and then dropping that role leaves the squatted role with no member at all, while the objects, settings and default privileges planted in it stay. The chart therefore records the roles it manages as members of "cozystack:managed", a role only the superuser can grant, and the delete passes act only on those. Its first run marks every role the chart had commented before, when no role could yet hold CREATEROLE through it. Once any user has held createRole, recorded as a setting of the postgres database, the chart refuses to adopt a role it did not mark and fails with the role's name, rather than hand a squatted role REPLICATION or the ownership of a database. Verified against live PostgreSQL instances. On 17 a migration checklist replayed as the login user, with no superuser: role creation with attributes, CREATE SCHEMA ... AUTHORIZATION with the requested owner, extensions in a named schema, per-role search_path and timeouts, RLS including FORCE ROW LEVEL SECURITY, and SECURITY DEFINER functions all succeed. On 17 the forged-comment and squatting paths are refused or ignored, the upgrade from the previous chart marks the roles it already managed, and a fresh install still adopts the role CNPG bootstraps for users.app. On 13, 15 and 16 the init script runs and re-runs cleanly.

feat(postgres): add a postgis image flavor (#4587)
<!-- Thank you for making a contribution! Here are some tips for you: - Use Conventional Commits for the PR title: `type(scope): description` - Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore - Scopes are not an exhaustive list — pick the most specific scope for the change and extend the list when a genuinely new area appears. Examples: - System components: dashboard, platform, operator, cilium, kube-ovn, linstor, fluxcd, cluster-api - Managed apps: postgres, mariadb, redis, kafka, clickhouse, virtual-machine, kubernetes - Development and maintenance: api, hack, tests, ci, docs, maintenance - Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or add a `BREAKING CHANGE:` footer - If it's a work in progress, consider creating this PR as a draft. - Don't hesistate to ask for opinion and review in the community chats, even if it's still a draft. - Add the label `kind/backport` if it's a bugfix that needs to be backported to a previous version. --> ## What this PR does Adds a `flavor: postgresql | postgis` enum to the `postgres` app. `postgis` runs the cluster on the CloudNativePG PostGIS operand image, so tenants can enable `postgis`, `postgis_raster`, `postgis_topology`, `postgis_sfcgal`, `postgis_tiger_geocoder` and `address_standardizer` through the existing `databases.<name>.extensions`. The default stays `postgresql` and renders exactly the image it rendered before this change. This picks up #2672 by @matthieu-robin, which the stale bot closed after a rebase request, with these changes: - The postgis tags in #2672 (`17.7-3.5`, `16.11-3.5`, ...) do not exist in `ghcr.io/cloudnative-pg/postgis`; the registry answers 404, so the flavor would have ended in `ImagePullBackOff`. The map now uses tags that exist, `<minor>-<postgis>-standard-trixie`, on the same PostgreSQL minor as `files/versions.yaml`. - v18 is supported: PostGIS images for 18 now exist upstream. - `standard` rather than `system`: the chart archives through the barman-cloud plugin since the backup rework, so the operand no longer needs the barman binaries of the deprecated `system` variant. - `hack/update-versions.sh` derives the postgis map from the minors it picks, and `hack/check-postgres-postgis-versions.bats` fails if the two maps drift to different minors or away from `standard-trixie`. - The chart refuses a flavor change on a live `Cluster`. The default images are built on Debian bullseye (glibc 2.31) and the postgis ones on trixie (glibc 2.41): CNPG would roll the swap out as a plain image update, under an initialised data directory, which silently invalidates every index on collatable text, and the postgis-to-postgresql direction also drops the libraries behind every PostGIS object. Only the image name is compared, so minor bumps and registry mirrors keep passing. - `pgrouting` is not claimed: it is absent from the `18.1-3.6.1` build the chart pins and only appears in later postgis builds. A general mechanism (CNPG ImageVolume extensions) was considered and left out: it needs PostgreSQL 18 and Kubernetes 1.35 or the `ImageVolume` gate, so it cannot serve v13-v17 nor most management clusters today, and PostGIS is the only extension CloudNativePG ships as a full operand image. No other extension request exists in this repository. Testing: - `helm unittest packages/apps/postgres`: 145/145, including 6 new cases in `tests/flavor_test.yaml` (default image, postgis on the Cluster and on the init Job, the guard in both directions with a mocked live Cluster, and a mirrored digest-pinned image taking a new minor). Removing the guard makes exactly the two guard cases fail. - `hack/cozytest.sh hack/check-postgres-postgis-versions.bats` passes, and fails on a shifted minor or a `system` tag. - `make -C packages/apps/postgres generate` leaves no diff. - The rendered `ghcr.io/cloudnative-pg/postgis:18.1-3.6.1-standard-trixie` was started locally: `CREATE EXTENSION` for citext, postgis, postgis_raster and postgis_topology succeeds and `ST_Buffer` answers. A three-instance cluster on the `system` sibling of that image has been running PostGIS in production since 2026-09-29. ### Screenshots <!-- REQUIRED for UI changes: attach screenshots or screen recordings demonstrating the visual impact of your changes.

fix(vm-instance): make the netplan network-data opt-in
Keying the network-data on instanceProfile reached every VM that never set the field, because the profile defaults to ubuntu whatever image the disk holds. The sysconfig, NetworkManager and eni renderers turn each match stanza into an interface literally named after the netplan ID, so a non-netplan guest left on the default profile would lose the DHCP it gets today. A VM with neither cloudInit nor sshKeys would also gain a cloud-init disk on upgrade, and KubeVirt's NoCloud instance-id is new to that guest, so its next boot would regenerate host keys as a first boot. The configuration also shadows a static NIC set up through netplan: netplan emits one networkd file per ID, networkd applies only the first file in lexical order that matches a link, and 10-netplan-cozy-en sorts before the file for enp2s0. The external-VLAN recipe claimed otherwise. An explicit netplanDhcp value, off by default, leaves every existing VM rendering exactly as before and lets the documentation say when not to turn it on.

fix(monitoring): count a central request as the receiver admitted it
The limiter refuses for good any request it counts above burst, and burst was the receiver's 4 MiB cap. A request grows on its way to the limiter: the sampler adds a tracestate to every span it keeps, and the limiter counts a request as the collector re-encodes it, which writes the empty value of every attribute the wire may omit, so a valid request of spans with empty-valued attributes is counted 1.4x. A request the receiver admitted near its cap was therefore refused on every retry. The limiter now runs right after memory_limiter, so it counts the request before sampling. The receiver caps a request at 3 MiB and burst stays at 5 MiB, which holds 1.4x the cap; a larger burst would also be what each pod start lets through above the rate. The rate is counted before sampling, so the store keeps only the sampled share of it. The texts say that a request above the cap gets a 400, which senders do not retry, and that each collector rollout a tenant causes lets that burst through again on every pod. The replica bound that keeps that allowance small now applies only to a central tenant's collector, whose render fails above ten replicas: a collector writing to the tenant's own store has no rate, and the replica counts it shipped with stay valid.

feat(monitoring): hold each shared-central tenant to a write rate
The design has the per-tenant collector rate-limit its tenant, so that a noisy or hostile tenant cannot exhaust a shared backend. The disk cap alone does not do that: VictoriaTraces always keeps the last two days, so a tenant writing faster than the cap allows over two days fills the disk for every tenant on the store. The platform sets the rate with monitoring.tracingCentralTenantBytesPerSecond, and it reaches every tenant in _cluster through the cozystack-values Secret. A change there is a change in the values each monitoring HelmRelease reads, so Flux upgrades them all; a rate read with lookup at render time would never reach a tenant whose release is already in sync. The platform writes the key only when it is set, since every release in every tenant reads that Secret. Without it the collector holds the tenant to the rate of a default 10Gi store. Each central tenant's collector splits the rate across its replicas and refuses data above it before the batch processor, so the sender sees the refusal. An OTLP/HTTP sender gets a 429 and retries; the limiter answers gRPC with RESOURCE_EXHAUSTED and no RetryInfo, which the OTLP specification makes final, so central tenants should export over HTTP.

fix(vm-instance)!: refuse guest memory below KubeVirt's 1M floor (#4569)

Before, a value such as `500m` or `1Ki` rendered and then failed when the VirtualMachine was applied. This is a breaking change. A memory above zero and below 1M rendered before and is now refused at render time. KubeVirt v1.9.0 would not admit such a VM either: `validateMemoryRequestsNegativeOrNull` refuses a non-zero request below 1M (`pkg/virt-api/webhooks/validating-webhook/admitters/vmi-create-admitter.go:1135`). The VirtualMachine admitter runs the same check on its template. The cpu, sockets and memory descriptions now list the values the guard refuses, so the schema states the same rule as the error. The error cannot quote an unquoted number as it was written, because YAML has decoded it before the chart sees it. A large one also printed in exponent form, so `4294967296` came out as `4.294967296e+09`. A string is still quoted exactly as written. A number is now printed in plain digits and marked "read as", which is the closest honest wording I found.

feat(redis)!: refuse external access without TLS at admission
A Redis release with external: true and TLS off publishes a plaintext endpoint outside the cluster, and nothing stopped a tenant from asking for one. The chart never infers TLS from external, because enabling it moves Redis to a TLS-only listener, so external: true without an explicit tls.enabled: true is exactly that case. A ValidatingAdmissionPolicy on the Redis kind now refuses it with a message naming the release and a remedy that works. TLS is fixed when a Redis instance is created: the operator's RedisFailover schema refuses a change, but the Redis API accepts it. A spec's tls.enabled is therefore a request, not the instance's state, and cannot prove on UPDATE that an instance has TLS; trusting it would let a tenant flip it, expose the instance, and remove it again. So external access can be enabled only at creation, where tls.enabled does decide the instance, and any UPDATE turning it on is refused. The RedisFailover schema does not exist before the first reconcile, so a release admitted as external with TLS could have TLS dropped before the instance is created. tls.enabled is therefore frozen while external access stays on. Withdrawing external access in the same edit lifts the freeze, which leaves a tenant a way to unblock an instance whose TLS was flipped earlier, and the callers trusted by the tenant host policy are exempt so an administrator can repair one in place. Other edits to an instance that is already external pass, so releases exposed in plaintext before the policy keep working. Postgres is left out on purpose. CNPG pins ssl=on, and its default pg_hba accepts plaintext from any client that asks, whatever the chart's tls.enabled says; that field only decides whether the external hostname goes into the certificate. A policy keyed on it would close nothing. The decisions are tested by compiling the shipped template with the apiserver's own CEL compiler, since a structural chart test cannot show what the policy admits. BREAKING CHANGE: creating a Redis with external: true and without tls.enabled: true, which applied before, is now refused, including a GitOps re-apply of such a manifest into a fresh cluster. Turning external on for an existing Redis is refused as well, so exposing an instance means creating a new one with TLS, and tls.enabled can no longer be changed on an instance with external access.

fix(vm-disk): report DataVolume readiness through WorkloadsReady (#4380)
## What this PR does Nothing on a vm-disk application tells whether CDI ever finished populating the disk. Its WorkloadMonitor has no pods to count, and `Ready` follows the Helm release. So an import or clone that never completes can leave a green application over a disk nobody can use. cozystack/cozystack#2908 is one way to get there: a clone into a StorageClass that cannot place a replica where the source data sits. The expensive part there was the silence, not the stuck clone. The disk state was in the DataVolume phase all along, and nothing read it. With this change the WorkloadMonitor in cozystack-controller reads it. The monitor lists the DataVolumes its selector matches and reports not operational while any of them is in flight, Failed, Unknown or has no phase. An upload counts as in flight until it completes. That surfaces on the application as `WorkloadsReady=False` with reason `DataVolumeNotReady` and a message that names the DataVolume and its phase, for example `DataVolume vm-disk-x is ImportInProgress`. `Ready` still follows the HelmRelease, as for any other kind (`convertHelmReleaseToApplication` in `pkg/registry/apps/application/rest.go`), and for a vm-disk it no longer waits on the DataVolume at all. So the disk state has to be visible outside `Ready`, and this PR puts it where operators look by default: - `kubectl get` on any application kind gets a `WORKLOADS` column next to `READY`. It shows the `WorkloadsReady` status, or `<none>` when the application has no WorkloadMonitor. - The console badge turns amber and reads `DataVolumeNotReady` while `Ready` is True and `WorkloadsReady` is not True for that reason. A failing `Ready` still wins. The console shows only the disk case: other kinds need a separate decision, because a stopped VM legitimately has no pod and reports `WorkloadsReady=False` too. A Helm readiness gate on the DataVolume would be the obvious alternative, and it is not used on purpose. helm-controller runs that wait inside its reconcile, so an importing disk would hold one of the shard's worker slots for the whole install window, and a disk stuck for good would keep taking the slot back. cozystack/cozystack#4145 has the details. The monitor costs no slot, keeps watching after install, and covers existing disks without anyone writing to them. Without any gate, the install would still wait on the DataVolume. helm-controller's default poller falls back to a resource's `Ready` condition for kinds it has no rule for (`checkReadyCondition` in fluxcd/cli-utils `pkg/kstatus/status/status.go`), so a vm-disk install could hold a worker slot for the whole install timeout. The ApplicationDefinition therefore gets a `healthCheckExprs` entry for DataVolume with `current: "true"`, the same idiom postgres-rd uses for its ScaledObject. With it Helm never waits on the DataVolume. The entry is pinned by a helm-unittest in `packages/system/vm-disk-rd`, which gets a `test` target for it. Release settings reach a HelmRelease only when the application is created or updated, so an existing disk gets the entry on its next update. The reconciler that syncs definitions onto existing releases copies chartRef, valuesFrom and labels only. That affects any kind with release settings, so it is filed as cozystack/cozystack#4409 and not fixed here. `WorkloadsReady` covers every disk right away, since the monitor needs no write to the application. CDI copies the DataVolume labels onto the PVC it creates and makes the DataVolume its controller, so the monitor also publishes a `pvc-<name>` Workload for the disk. That Workload reads not operational while its DataVolume is not ready, even though the PVC is already Bound, so `kubectl get workloads` agrees with `WorkloadsReady`. While the DataVolumes cannot be read it keeps the verdict it has, like the monitor. The WorkloadMonitor CRD now requires at least one selector label. An empty selector would match every Pod, PVC, Service and DataVolume in the namespace. No chart renders one. When an application has several monitors that are not operational and only some of them name a cause, `WorkloadsReady` carries the named messages and reason only. A vm-disk has one monitor, so it does not hit this. ### Which phases count as ready Settled phases pass: `Succeeded`, `PendingPopulation`, `WaitForFirstConsumer`, `Paused`. A disk with `bindImmediately: false` on a `WaitForFirstConsumer` class rests in `PendingPopulation` or `WaitForFirstConsumer` until a VM consumes it. A multi-stage import rests in `Paused` until its next checkpoint, and the vm-disk chart renders no checkpoint source. These report ready while holding no data, because that is where such a disk is supposed to sit. `UploadReady` is not one of them. CDI enters it when the upload server pod is running and ready, and leaves it for `Succeeded` only when that pod succeeds (`updateStatusPhase` in `pkg/controller/datavolume/upload-controller.go` at v1.66.1), so the one phase covers a disk nobody has uploaded to and a half-uploaded one. A `source: upload` disk therefore reports `WorkloadsReady=False` from creation until `virtctl image-upload` completes. A phase the controller does not know also reads as ready, so a CDI release that adds or renames a phase cannot turn working disks red. The cost goes the other way: a renamed in-flight phase silently reads as settled. The list wants a re-read whenever the CDI version moves. It matches the named phases of the CDI v1.66.1 API, the version vendored in `packages/system/kubevirt-cdi-operator`. ### Clusters without CDI CDI comes with the IaaS bundle, while cozystack-controller runs everywhere, and CDI can be installed while the controller is running. A watch on a kind whose CRD is absent never syncs, and then the whole controller does not start. So the watch is not set up at startup. A runnable adds the DataVolume watch once the kind is served. It waits for the first reconcile, because only from then on does a new watch start at once, and then checks discovery right away and every 30s after that. It installs the DataVolume reader only after the DataVolume informer has synced within a timeout, because a reconcile context has no deadline and a List on an informer that never syncs would block every WorkloadMonitor reconcile. The watch source is started once: a controller-runtime `Kind` source adds an event handler to the informer and never removes it, so on a timeout the next check waits on the source it already has instead of starting another one. RBAC needs no change: the controller's ClusterRole already has read on everything. When the DataVolumes cannot be read, because the reader is not installed yet or the List fails, the monitor still publishes its replica counts and keeps its last DataVolume verdict, and a List error is returned so the request is retried and recorded as a `DataVolumesUnavailable` Warning event on the monitor. The status of a monitor without DataVolumes is not affected by a failing List. A disk whose verdict is already recorded does not read as ready in the window after a controller restart. A monitor with no recorded verdict yet, which is every monitor right after the upgrade that brings this change and any disk created right after a restart, reads ready until the DataVolume watch has synced. Because the watch starts on the first reconcile rather than on the next discovery tick, that window is the time to sync the DataVolume informer plus at most one 5s requeue, not a 30s poll interval. The window is not zero, since a monitor reconciled in it is published before its DataVolumes can be read. From then on, a reconcile that runs before the watch has synced is requeued after a few seconds, so the DataVolume events that queue it are not lost. A pass that changes nothing in the monitor status does not write it, so that requeue sends no status writes to the API server. Once the reader is installed, every monitor that holds a DataVolume verdict is queued once more. So a verdict whose DataVolume was deleted while the controller was down is recomputed then, not at the periodic resync. ### Tests The table test in `workloadmonitor_controller_test.go` covers the named phases of CDI v1.66.1, plus Failed, Unknown, an empty phase and a missing status. A second table checks the message and reason for an importing, a failed, a phaseless and a populated disk, and a third test lists two stuck DataVolumes in both orders and expects one message. It also covers a DataVolume outside the selector, the kind not being served, a List error that still publishes the replica counts, and a missing reader that keeps the last verdict. The watch tests check that the watch starts on the first reconcile and not before it. A source that never syncs leaves no reader and is retried on the same source, with the reconciles in between still requeued. A List failure records the Warning event, the sync window records none, and an unchanged pass writes no status. A manager that stops during the wait gets the cancellation back, and a reconcile that runs while the watch syncs is requeued without an error. A table test covers the PVC Workload: importing, populated, a PVC with no DataVolume controller or a controller of another kind or group, and the unread cases. A helm-unittest in `packages/system/cozystack-controller` pins the selector's `minProperties`. `rest_table_test.go` pins the `WORKLOADS` column, `rest_workloads_test.go` the condition message and reason, and `status.test.ts` the console badge, including a halted VM that stays green. In `hack/e2e-chainsaw/vminstance` the existing VMDisk scenarios now wait for the DataVolume to be Ready, then for `Ready` and `WorkloadsReady` on the VMDisk itself. That replaces the wait on the HelmRelease. Those asserts would pass even if the monitor ignored DataVolumes, so a new scenario imports from an `.invalid` URL. It first waits for the importer to have failed, which CDI reports on the DataVolume as `Running=False` with reason `Error`, and then for `Ready=True` with `WorkloadsReady=False` and reason `DataVolumeNotReady` on the VMDisk. Without the first wait the VMDisk assert passed in about a second, on a DataVolume that had no phase yet. The e2e runs on a fresh install only, so nothing here exercises an existing release across an upgrade. ### What it does not do #2908 lists possible fix directions, and none of them is here. The cross-class clone still never completes, it just stops being invisible. Keep the issue open. While the DataVolume watch syncs, every monitor is still requeued. Only the ones whose selector reaches a DataVolume need it, but the controller cannot tell which those are before it can read DataVolumes. Closes #4449 ### Screenshots There is no screenshot: I had no running console to take one from. The badge change is pinned by the vitest cases in `packages/system/dashboard/images/console/apps/console/src/lib/status.test.ts`: a VMDisk whose `WorkloadsReady` has reason `DataVolumeNotReady` goes amber, and a halted VMInstance with the generic reason stays green. ### Downstream repositories I walked the trigger map against the diff. cozystack/terraform-provider-cozystack is affected: its `wait_for_ready` reads only `Ready`, so on a `cozystack_vmdisk` it returns before the disk is populated once this lands. That needs a decision on the provider side, so it is an issue there. The release-time bot regenerates `packages/apps/vm-disk/README.md` into the website's virtualization pages, and `vm-disk` is in the `VMS` list that generator reads, so the website needs no follow-up. The ApplicationDefinition keeps its kind, plural, prefix and path. - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [x] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: https://github.com/cozystack/terraform-provider-cozystack/issues/59 - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note fix(vm-disk): report whether CDI finished populating a disk in the WorkloadsReady condition, which names the stuck DataVolume and its phase. kubectl get shows WorkloadsReady in a new WORKLOADS column for every application kind, and the console badge turns amber while a disk is not populated, so a disk whose import or clone never completes no longer looks healthy.

fix(kubernetes-nodes): refuse a resources.cpu that cannot be a core count (#4386)
## What this PR does A worker pool's CPU value could land in the VM as something KubeVirt cannot accept. `resources.cpu` is typed as a quantity, but on the kubevirt substrate the template wrote it unchanged into `domain.cpu.cores`, which is `uint32` in KubeVirt and an integer in the KubevirtMachineTemplate CRD. With `resources.cpu: 500m` the chart rendered `cores: 500m`. That string was truthy, so it also counted as explicit sizing and dropped the pool's `instanceType` from the VM, and then the API server refused the template anyway. The render now decodes the value as YAML, the same way `cores: <raw>` is decoded, and stops unless the result is a whole number from 1 to 4294967295. `500m`, `"1.5"` and `"1e10"` now fail at render time with an error naming the field, before the value reaches the VM template or the instancetype decision. `"0"` and `"-2"` were already refused on `main` and still are. Only inputs that could not produce a working pool are refused. Every value that rendered a pool before renders the same bytes now, so the content-hashed template keeps its name and nothing rolls. That includes `2`, `"2.0"`, `"+2"` and `"1e1"`, and also two odd cases I kept on purpose because pools may already carry them. An unquoted `0` is falsy, so the pool renders without `domain.cpu` and is sized by its instancetype, as on `main`. A leading-zero value such as `"010"` is still emitted as written and keeps the reading it gets on `main` today, where YAML treats it as octal. I checked both against a render of `main`, and the tests pin the template names that `main` produces for them. This is where kubernetes-nodes and vm-instance now differ. Since #4405, vm-instance refuses a leading zero and an unquoted `0`, and this chart does not. Stored worker pools can carry these values, because migration 56 copies `resources` verbatim, so refusing them here without a migration would fail those pools' releases on their next upgrade. #4554 tracks the migration and the refusal after it. The proxmox substrate is not checked. It converts the quantity to millicores and rounds up to whole cores, so `500m` is a valid size there and becomes one core. The field description now says what the value means on each substrate. Memory is left alone. It goes to `domain.memory.guest`, which is a `resource.Quantity`, so a quantity string is valid there. The issue suggested coercing to an integer, as vm-instance did before #4405. I didn't, because `int64` turns `500m` into `0` without an error. The new helm-unittest suite covers each input form, both preserved cases, the upper bound, the instancetype case and the proxmox path. Two neighbouring descriptions still say only "CPU available.": `nodeGroups[].resources.cpu` in `packages/extra/computeplane` and in the parent `kubernetes` chart. computeplane passes `resources` straight into this chart, so the new check applies to its pools as well. I left both alone to keep this change to one chart.

feat(controller): tag a DataVolume cause with a condition reason
WorkloadsReady=False covers different situations: a stopped VM has no pod and its monitor reports it not operational on purpose, while a disk whose DataVolume never populates is broken. A consumer that wants to react to one and not the other had only the message text to go by. The WorkloadMonitor status gains a Reason next to Message, set to DataVolumeNotReady by the DataVolume check, and the Application API carries it into the WorkloadsReady condition in place of the generic reason whenever a monitor that is not operational names one.

feat(controller): name the DataVolume that keeps a disk not ready
For a vm-disk, WorkloadsReady is the one condition that reports whether CDI populated the disk, and its generic "One or more workloads are not operational" gives an operator nothing to act on: a disk has no workloads, and the stuck DataVolume and its phase are exactly what they need to know. The WorkloadMonitor status gains a message that the controller fills with each selected DataVolume that is not ready and its phase, and the Application API uses the messages of the monitors that are not operational in WorkloadsReady instead of the generic text whenever one of them names a cause.

feat(monitoring,tenant): shared-central tracing topology (phase 4) (#3775)
## What this PR does Adds the opt-in shared-central traces topology from the distributed tracing design (cozystack/community `design-proposals/distributed-tracing`, rollout item 4): a tenant can send its spans to one VictoriaTraces store in tenant-root instead of running its own, with both write and read isolation between the tenants that share it. **Switching it on.** A tenant opts in with the new Tenant field `tracingCentral`, which needs the tenant's own Monitoring. The tenant chart publishes it to the tenant's monitoring charts as `_namespace.tracingCentral` in the `cozystack-values` Secret, which the apps API does not let an application write, and renders the two network paths the topology needs under the same condition. tenant-root decides whether it hosts the store, with the new Monitoring field `tracingCentralHost` next to a cluster-mode `tracingStorages` entry named `generic`. **Isolation.** VictoriaTraces takes the tenant account from the `AccountID`/`ProjectID` headers and does no authorization of its own, so other tenants reach the shared store only through a vmauth in tenant-root. Each central tenant gets a VMUser that pins an account derived from its namespace name and UID, for both its collector's writes and its Grafana reads, and vmauth overrides any account a client sends. The collector and Grafana log in with credentials the chart generates and keeps. The tenant egress rules allow only pods carrying the collector's or Grafana's label to reach the vmauth proxy port, and a pod that carries such a label without the tenant's credentials gets only 401 from it; the vmauth internal routes, whose `/metrics` lists every tenant's user, are served on a port tenants cannot reach. The tenant-root namespace itself is inside the trust boundary, as it already is for the metrics of tenants that rely on a parent's monitoring: its workloads reach the store directly, and one that learns a tenant's account ID can read and write that account, and whoever tenant-root admits to its Grafana reads the store through a datasource that bypasses vmauth (with the System oidc mode, tenant-root's own groups, which already hold the same access level in every tenant under it); the `tracingCentralHost` description says so. **Sharing the store.** Each tenant's VMUser is capped at four requests in flight per vmauth replica, reads and writes together, and each collector replica exports with two senders, so more collector replicas do not raise a tenant's throughput; above the cap vmauth queues for up to 10s and answers 429, which the exporter retries. The store has one disk and one retention for all of its tenants and nothing reserves space per tenant; `tracingCentralHost` states that, since hosting is tenant-root's decision. The vmauth runs two replicas spread across nodes under a PodDisruptionBudget, so draining one node does not stop every central tenant at once. Every traces store is also disk-bounded now, as the design requires: without `retentionDiskUsageBytes` it drops its oldest day once its filesystem is 80% full. That alone does not keep one tenant from filling the shared disk, since VictoriaTraces always keeps the last two days. **States that would drop spans silently are refused, one race aside.** A live render fails, with a message naming the prerequisite, when a tenant turns central on while tenant-root hosts nothing, and when tenant-root stops hosting while central tenants remain; tenant-root's render also refuses `tracingCentralHost` without a store to host. The second check does not wait on a VMUser that is already being deleted, since its tenant is leaving. Each check reads the other side's objects when it renders, so a tenant turning central on while tenant-root stops hosting can pass both and export to a vmauth that is gone; the `tracingCentralHost` description names this race and its recovery. At runtime, tenant-root's Monitoring release is not Ready while the vmauth has failed. These checks run on a render, so removing the tenant-root Monitoring altogether is not refused, and from then on every Monitoring render of a central tenant fails until it turns central off; the `tracingCentralHost` description says to turn central off on the tenants first. Turning central on keeps the tenant's own local stores and their datasources, so traces stored before the switch stay readable until the tenant removes them; turning it off again leaves the spans written meanwhile in the shared store, unreadable from the tenant until it turns central on again, and spans sent while the collector switches back may be dropped; a deleted tenant's spans likewise stay until retention drops them. Right after a tenant turns central on, or after its credentials Secret is re-created, spans its collector sends before the vmauth has loaded the new login get a 401, which the exporter does not retry, so they are dropped; the tracing guide in #3772 covers it. **Where this departs from the design.** The design has the per-tenant collector inject the account headers and adds exactly one egress rule. Here the account is pinned by the tenant's VMUser at the vmauth and the collector sends none, because the collector runs in the tenant namespace and whatever runs with its pod label could otherwise choose an account; vmauth is also what the design already requires for reads, so both directions go through it. That needs a second egress rule, for the tenant's Grafana to reach the vmauth, beside the collector's. The per-tenant write rate the design gives the collector is not in this PR: no OpenTelemetry distribution has a rate-limiting processor, so #4648 builds the collector with one and holds each central tenant to a rate tenant-root publishes. Until it lands, a tenant writing faster than the disk cap allows over two days can fill the disk the other tenants share. **Consent is per host, not per tenant.** `tracingCentralHost` lets every tenant that sets `tracingCentral` in, nested tenants included, and each gets its own VMUser and its own request cap; there is no allow-list. A tenant-root that needs to limit who shares its store keeps `tracingCentralHost` off. **Upgrade.** Tenants that do not opt in render the same objects as before, and their `cozystack-values` Secret is unchanged. The monitoring charts render the same objects too, with one exception: a VTSingle or VTCluster without `retentionDiskUsageBytes` gains `retention.maxDiskUsagePercent: "80"` in its `extraArgs`, so its spec changes and its storage pods restart once, and a store already more than 80% full drops its oldest days when it starts. The inner monitoring HelmRelease's values gain the new `tracingCentralHost: false` default, as with any new field, and its `healthCheckExprs` gain a `VMAuth` entry, which matches nothing outside a hosting tenant-root. Both change the HelmRelease spec, so every tenant's monitoring release upgrades once, rendering the same objects. A tenant-root that has a cluster-mode `generic` store gets no vmauth until it sets `tracingCentralHost`. **Testing.** helm-unittest covers the three charts the change touches (tenant, monitoring, extra monitoring) and every guard was checked by mutation; a bats test covers what helm-unittest cannot, that the generated password and the collector's rollout checksum agree on a first install. On a test cluster: a spoofed `AccountID` from a tenant is overridden by vmauth, one tenant cannot read another's spans, the vmauth starts under the real tenant network policies (and stays in init without its apiserver label), the guards refuse as described, and the rendered collector config passes `otelcol validate` in the pinned image. There is no end-to-end test yet; one that covers cross-tenant isolation is planned as a follow-up. ### Screenshots No UI changes. ### Downstream repositories - [ ] No downstream repository is affected by this change - [x] [cozystack/website](https://github.com/cozystack/website) - follow-up: covered by cozystack/cozystack#3772, the tracing guide - [x] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: cozystack/terraform-provider-cozystack#64 - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: The Tenant gains the user-facing field `tracingCentral` (bool, default false), which the trigger map sends to terraform-provider-cozystack: its hand-written Tenant schema and model need the field.

fix(kubernetes-nodes): refuse a resources.cpu that cannot be a core count
On the kubevirt substrate a worker pool's resources.cpu, although schema-typed as a Kubernetes quantity, is written verbatim into domain.cpu.cores, which KubeVirt declares as uint32 and the KubevirtMachineTemplate CRD as an integer. A value such as 500m or "1.5" therefore rendered a template the API server refuses, and because the same raw string was truthy it also counted as explicit sizing and dropped the pool's instancetype matcher first. A whole count past the uint32 ceiling rendered too, although KubeVirt cannot hold it. The render now decodes the value the way the emitted cores field is decoded and stops unless that is a whole number between 1 and the uint32 maximum, before the value reaches the VM template or the precedence decision. Only inputs that could not produce a working pool are refused. Every value that rendered one still renders the same bytes, so no pool rolls: a bare numeric zero stays falsy and means unset, and a leading-zero spelling is still emitted as written. The proxmox substrate is left out of the check, because it converts the quantity to millicores and rounds up to whole cores, so 500m is a valid size there. The field description now says what the value means on each substrate. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <f@lex.la> |

fix(postgres): refuse a physical restore across image flavors
A recovery replays the source's data directory, so it carries the same risk as switching the image of a live cluster: the postgresql and postgis images are built on different Debian releases, and the glibc change invalidates collatable indexes, while a postgis-to-postgresql move also loses the libraries behind every PostGIS object. The chart only guarded the live cluster, so a fresh release bootstrapped from a backup of the other flavor went through, and the guard's own advice was to restore a backup, which is that very move. The backup-controller now records the source flavor in the snapshot it stores on each Backup and fails a RestoreJob whose target runs another flavor, before the purge deletes the target's Cluster and PVCs. A snapshot without a flavor predates flavors and so comes from a postgresql cluster. For the chart-managed bootstrap, the chart compares against the recovery source's Cluster while it still exists. Both paths, and the live-cluster guard, point a flavor change to a logical dump. Assisted-by: LLM Signed-off-by: Mattia Eleuteri <mattia@hidora.io> |

feat(postgres): add a postgis image flavor
Tenants migrating spatial data need PostGIS, but the chart always runs the CloudNativePG PostgreSQL image, which does not ship it, and exposes no way to pick another one. CloudNativePG publishes a PostGIS operand image; a closed `flavor` enum selects it without handing tenants a free image field. The flavor pins the same PostgreSQL minor as the default one, on the standard-trixie variant: backups go through the barman-cloud plugin, so the deprecated system variant is not needed. update-versions.sh now derives the postgis map from the minors it picks, and a bats check fails if the two maps drift apart. The default images are built on bullseye and the postgis ones on trixie. Switching a live cluster between them would swap glibc under an initialised data directory and silently break every collatable index, and CNPG would roll it out as a plain image update. The chart therefore refuses a flavor change on an existing Cluster. Co-authored-by: Matthieu <matthieu@hidora.com> Assisted-by: LLM Signed-off-by: Mattia Eleuteri <mattia@hidora.io> |

docs(tenant): shorten the tracingCentral description
The description ships in the godoc, the schema, the README, the ApplicationDefinition and the dashboard's field help, and at about 2,800 characters it buried what an operator needs to decide on the field. It now says what the field does, what tenant-root has to host first, and who is inside the shared store's trust boundary; the lifecycle details move to the user guide.

feat(harbor): restrict the portal and API to listed source ranges (#4300)
## What this PR does Adds `managementWhitelist` to the Harbor app, a list of IP addresses or CIDR ranges allowed to reach the web portal and the Harbor API, and I made it a typed list on purpose. The obvious alternative, a free-form `ingress.annotations` map, gives tenants a way into the shared ingress controller. The platform ingress-nginx runs with `allowSnippetAnnotations: true` (the kubernetes app needs a `configuration-snippet`), and v1.11.5 defaults `annotations-risk-level` to `Critical`, so it accepts any annotation, `server-snippet` included. Tenants can't create Ingress objects themselves, but they can write any field of an app spec. An annotation map on the Harbor spec would let any tenant put arbitrary nginx config into a controller that serves every tenant. A typed list is also what the repo already does for this: `filer.whitelist` in `extra/seaweedfs`, `whitelist` in `extra/ingress` and `tcp-balancer`. The use case is a registry that serves customers: pulls and pushes come from anywhere, the admin UI and API should answer only to an office or VPN range. Right now the portal, `/api/v2.0` and `/v2/` sit on one Ingress and one public host, and a tenant can't restrict any of them. With a non-empty list the existing Ingress gets `nginx.ingress.kubernetes.io/whitelist-source-range`, and `/v2` and `/service/token` move to a second Ingress, `<release>-registry-ingress`, on the same host. ingress-nginx applies that annotation only to the locations of the Ingress that carries it, so those two stay open. They are what a registry client needs: Harbor answers an anonymous `/v2/` request with a Bearer challenge whose realm is `/service/token` on the same host. Everything else under `/service/` is `/service/notifications/*`, internal job callbacks that the bundled nginx already answers with 404, so it stays on the restricted side. The second Ingress uses the same TLS secret and has no cert-manager annotations, otherwise ingress-shim gets two owners for one Certificate. The HTTP-01 solver is its own Ingress and is not restricted. With the default empty list the chart renders exactly what it renders today. An HTTPRoute can't express a source restriction, so in Gateway API mode a non-empty list fails the render. Dropping it silently would leave the portal public while the spec says it is restricted. Each entry has to be an IP address or CIDR range, and a bad one fails the render. ingress-nginx reads an empty `whitelist-source-range` as no restriction and turns an unparseable one into a 503 for the whole location, and the values schema generator can't validate list items. Three things users should know. Harbor-to-Harbor replication that pulls from this registry goes through its API, so the other registry's address has to be on the list. The check uses the client address that ingress-nginx sees: with `externalTrafficPolicy: Local` or PROXY protocol that is the real client, behind another proxy it is the proxy. And for the portal and API the list replaces the tenant ingress `whitelist` rather than narrowing it. Disabling the portal is not here. The vendored Harbor chart (1.19.1) always renders the portal Deployment and its internal nginx always proxies `/` to it, so there is no small switch to wire. The new Ingress is added to the dashboard Role and to the ingress selector in the ApplicationDefinition. ### Screenshots No UI code change. The field reaches the dashboard form through the regenerated schema and `keysOrder`. ### Downstream repositories The terraform provider models Harbor by hand, so the new field needs a follow-up there: cozystack/terraform-provider-cozystack#46. The website reference page is generated from `README.md` on release. Nothing else in the trigger map is touched: no package added or renamed, no platform, installer or `hack/` change. - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [x] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: https://github.com/cozystack/terraform-provider-cozystack/issues/46 - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note feat(harbor): add `managementWhitelist`, a list of IP addresses or CIDR ranges allowed to reach the Harbor web portal and API. Only `/v2/` and `/service/token` stay reachable from any address. The default is an empty list, which keeps the current behaviour. Not supported with Gateway API publishing: a non-empty list fails the render there. Each entry must be an IP address or CIDR range; for the portal and API the list replaces the tenant ingress `whitelist`. ``` |

feat(tenant): let a tenant opt into shared-central tracing
tracingCentral turns the shared-central topology on for a tenant with its own Monitoring: it publishes _namespace.tracingCentral for the tenant's monitoring charts and renders the only two cross-boundary paths that topology needs, the collector and Grafana each to the tenant-root vmauth. Both come from one condition, so a tenant never exports to the shared store without the path, or gets the path without opting in, and tenant-root, which hosts the store, gets neither. The flag is written only for tenants that opt in: every application in a tenant reads that Secret, and a new key for all of them would re-upgrade them all on the platform upgrade.

fix(kubernetes): assemble the node group once in kubernetes-nodes
The TalosConfigTemplate name is a hash of the machine-config spec, and two
templates have to agree on it: talos-reconcile-job.yaml creates the object,
nodegroup.yaml points MachineDeployment.bootstrap.configRef at it. Sharing the
rendering was not enough — each file also assembled its own $group dict, one
carrying every pool value and one only the few the spec reads, so the two
names agreed only by coincidence of the keys the spec helper happens to read.
Dropping "gpus" from the Job's dict diverged them on a GPU pool with the whole
suite still green, which is the "templates do not exist" deadlock this fix
exists to make impossible.
Move the assembly into a single kubernetes-nodes.group helper, read back with
fromYaml at both call sites, so there is one input as well as one rendering.
Cover it too, since the seam can be reintroduced. The chart's helm-unittest
suites pin each name against its own literal in its own file, which catches a
divergence but reports it as one literal having moved — indistinguishable from
a stale fixture, so re-pasting the new value is the obvious and wrong repair.
hack/check-talosconfigtemplate-name-agreement.bats renders the chart once and
compares the two values against each other, so the failure states the invariant
instead of a number. It asserts on a GPU-shaped pool as well as the default
one: the default renders gpus [], kubelet {} and instanceType "" as falsy, so a
consumer reading a subset of the group is indistinguishable there from one
reading all of it. kernelModules gets a case of its own, because it has no
default and stays unset on both of those shapes. A last case pins that the
shapes hash differently, so the others cannot hold vacuously.
The same guard compares the talos-reconcile Role's resourceNames on
TalosConfigTemplates against that name. The Job applies server-side, and
that is a PATCH on the name even when it creates the object, so a Role
naming anything else leaves the Job Forbidden and the pool without a
template, with the same silent outcome.
Document that talos.registryMirrors and kernelModules sit inside the hashed
spec, so changing either rolls the pool's existing workers instead of only
affecting nodes created later. The kernelModules text described the
fixed-name template as the present state and the content-hash name as a
future one.
No rendered output changes: the golden render snapshots are unchanged.
