## What this PR does Adds a `ValidatingAdmissionPolicy` that blocks `DELETE` on critical platform objects labeled `platform.cozystack.io/no-delete=true`. Native, in-process CEL evaluation — no webhook DaemonSet, no Service, no TLS, no image to maintain. Requires Kubernetes 1.30+. This is an alternative to the closed #2402 (admission webhook approach). ### Protected objects (labeled in this PR) | Resource | Kind | Source | |---|---|---| | `cozy-system` | Namespace | `packages/core/installer/templates/cozy-system-{namespace,labels}.yaml` | | `tenant-root` | Namespace | `packages/system/cozystack-basics/templates/tenant-root.yaml` | | `tenant-root` | HelmRelease (ns: tenant-root) | same | | `cozystack-version` | ConfigMap (ns: cozy-system) | `packages/core/platform/templates/cozystack-version.yaml` | | `cozystack-packages` | OCIRepository (ns: cozy-system) | `packages/core/platform/templates/repository.yaml` | | `letsencrypt-prod`, `letsencrypt-stage`, `selfsigned-cluster-issuer` | ClusterIssuer | `packages/system/cert-manager-issuers/templates/cluster-issuers.yaml` | | `linstorcluster` | LinstorCluster | `packages/system/linstor/templates/cluster.yaml` | | `packages.cozystack.io`, `packagesources.cozystack.io` | CRD | label stamped in `internal/crdinstall/install.go` | ### Bypass ```bash kubectl label <kind> <name> platform.cozystack.io/no-delete- kubectl delete <kind> <name> ``` ### Why VAP instead of a webhook Same outcome as #2402 but with zero runtime infrastructure: no DaemonSet, Service, TLS certificate, or image. The kube-apiserver evaluates the CEL `expression: "false"` in-process and denies because `validationActions: [Deny]`. `objectSelector` on the binding scopes evaluation to labeled objects only — every other DELETE in the cluster is unaffected. ### Release note ```release-note feat(platform): add deletion-protection guardrail (ValidatingAdmissionPolicy) blocking DELETE on cozystack platform objects labeled `platform.cozystack.io/no-delete=true`. Bypass by removing the label first. Requires Kubernetes 1.30+. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Deletion-protection guardrail: objects labeled platform.cozystack.io/no-delete=true are denied DELETE requests; removal of the label allows deletion. * **Chores** * Platform migration to v43 backfills the no-delete label onto system resources and namespaces. * **Tools** * Added an "unprotect" teardown utility to remove the no-delete label for uninstall/disaster recovery. * **Documentation** * Helm NOTES now warns when the guardrail is inactive due to missing cluster API. * **Tests** * New tests and e2e checks validate deletion-protection behavior. <!-- review_stack_entry_start --> [](https://app.coderabbit.ai/change-stack/cozystack/cozystack/pull/2650?utm_source=github_walkthrough&utm_medium=github&utm_campaign=change_stack) <!-- review_stack_entry_end --> <!-- end of auto-generated comment: release notes by coderabbit.ai -->
