Annotate storageClass as immutable across every stateful app whose
chart exposes one — clickhouse, foundationdb, harbor, http-cache,
kafka (Kafka + ZooKeeper), kubernetes (top-level only), mariadb,
mongodb, nats, openbao, opensearch, postgres, qdrant, rabbitmq,
redis, vm-disk. Without coverage across the catalogue the UI would
render storageClass read-only on some apps and editable on others —
a worse mental model than uniform behaviour.
The annotation lands at the schema layer (CEL XValidation rule
'self == oldSelf' on values.schema.json / types.go / embedded
openAPISchema in cozyrds/<app>.yaml). The cozystack aggregated
apiserver does not yet evaluate CEL on application-backed resources;
that is tracked at cozystack/cozystack#2657. The UI
(cozystack/cozystack-ui#6) consumes the marker today.
The PVC-pinning argument is identical for every chart: Kubernetes
fixes a PVC's storageClassName at creation time, so editing this
field on an existing resource never migrated data. The schema
annotation makes that contract explicit.
kubernetes.nodeGroups[name].storageClass is intentionally NOT
annotated: the field is optional and undefaulted, so a strict
'self == oldSelf' rule would block any future attempt to set it on
an existing node group. A richer ratcheting form is needed there —
see docs/storage-immutability.md.
A refactor in pkg/registry/apps/application/rest.go extracts the
inline schema-build path into buildSpecSchema so it can be
unit-tested. Three regression tests in rest_spec_schema_test.go pin
the contract that x-kubernetes-validations survives the
v1->internal->structural conversion (loaded from the actual MariaDB
ApplicationDefinition fixture on disk, not a hand-edited mock).
Each per-app README gains a one-line blockquote pointing to a new
docs/storage-immutability.md that explains the contract and which
consumers enforce it today.
Requires cozystack/cozyvalues-gen with @immutable support — bump the
pre-commit pin in .github/workflows/pre-commit.yml once the release
exists.

Rewrite resourcesPreset values in every apps/* and extras/* chart from
the legacy flat names to the new instance-type form, using the 1:1
mapping:
nano -> t1.nano micro -> t1.micro
small -> t1.small medium -> c1.small
large -> c1.medium xlarge -> c1.large
2xlarge -> c1.xlarge
Each affected values.yaml carries the canonical 47-value enum (40
instance-type names plus 7 legacy aliases) so the schema accepts both
forms during the deprecation window. cozyvalues-gen regenerates the
matching api/apps/v1alpha1/*/types.go kubebuilder enum and defaults,
the chart values.schema.json, the README parameter table, and the
ApplicationDefinition openAPISchema in packages/system/*-rd/cozyrds.
Three hardcoded legacy literals in chart templates migrated:
- packages/apps/harbor/templates/harbor.yaml:121 (portal)
- packages/apps/opensearch/templates/opensearch.yaml:43 (dashboards)
- packages/system/keycloak/templates/sts.yaml:115 (heap fallback)
packages/apps/foundationdb/Makefile gains the missing hack/update-crd.sh
call. Without it, every regen left foundationdb-rd cozyrds stale and
new FoundationDB app CRs through cozystack-api were rejected at
validation for any non-legacy resourcesPreset value.
Every default-rendered chart produces identical CPU and memory to the
value applied before the rename, courtesy of the legacy alias table in
cozy-lib and the 1:1 default mapping.
