fix(monitoring-agents): let the release uninstall when the VictoriaMetrics operator is gone first - #5152
Disabling the Monitoring Agents addon of a tenant Kubernetes cluster leaves <cluster>-monitoring-agents (release cozy-monitoring-agents, installed into the tenant cluster) in UninstallFailed for good. Seen in production on 1.6.5 and still reproducible from main.
monitoring-agents, victoria-metrics-operator and vertical-pod-autoscaler-crds in packages/apps/kubernetes/templates/helmreleases/ are all gated on addons.monitoringAgents.enabled, so they disappear together and Flux uninstalls them in parallel: dependsOn is not honoured on deletion. Two things then break the uninstall of monitoring-agents:
The VictoriaMetrics operator is often gone first. The operator's apps.victoriametrics.com/finalizer stays on the VMAgent, nobody removes it, and the deletion hangs. The manual workaround was to strip the finalizer, after which GC removes the VMAgent's Deployment, Service, Secrets and ServiceAccount through their owner references.
The VPA CRD was deleted with its own release while the stored manifest still contains VerticalPodAutoscaler vpa-vmagent, so Helm cannot build the manifest to uninstall. That root cause is fixed by fix(kubernetes): keep tenant addon CRDs when a release is uninstalled #3586 (helm.sh/resource-policy: keep on the tenant addon CRDs), which this PR does not redo.
This PR:
adds a pre-delete hook (templates/vm-cleanup-hook.yaml) that deletes every VictoriaMetrics object the release owns, waits up to 60s for a live operator to finalize them properly, and clears their finalizers by hand when it has not. Objects are selected through Helm's meta.helm.sh/release-name / release-namespace annotations rather than by name, so the 34 VMRules rendered from alerts/ and the VMServiceScrape in cozy-victoria-metrics-operator are covered along with the VMAgent. The kinds handled are every VictoriaMetrics kind the chart renders: VMAgent, VMRule, VMServiceScrape, VMPodScrape, VMNodeScrape. Operator v0.68.4 only finalizes the VMAgent; the other kinds are covered in case another operator version finalizes them, and for them the patch is a no-op. A kind whose CRD is already gone is skipped, and the script always exits 0, since a failing pre-delete hook would itself block the uninstall. The Job is bounded by activeDeadlineSeconds: 180 and backoffLimit: 0; its kubectl calls carry no --request-timeout, which would make kubectl skip the in-cluster credentials (hack/check-hook-request-timeout.bats) and reuses the digest-pinned docker.io/clastix/kubectl:v1.32 image the etcd-operator hook uses, via a new kubectlImage value. The shape follows packages/system/forklift/templates/forklift-cr-cleanup-hook.yaml.
The hook's RBAC is a ClusterRole/ClusterRoleBinding, limited to get, list, delete, patch on the five operator.victoriametrics.com resources, rather than Roles. The objects span two namespaces, and a Role in cozy-victoria-metrics-operator could not be created if that namespace were already gone or terminating, which would fail the hook and the uninstall with it. All hook objects carry hook-succeeded,hook-failed,before-hook-creation except the Job, which keeps a failed pod for its logs (ttlSecondsAfterFinished: 600), as in the forklift hook.
When the operator is already gone, clearing the finalizer skips whatever the operator does on finalize, notably the cluster-scoped RBAC it creates for the VMAgent, which has no owner reference. That residue is the same the manual workaround left, and it is no worse than today's stuck release; removing it would mean hard-coding the operator's naming scheme for those objects, which I preferred not to do.
When the operator is alive, the hook only brings forward deletions Helm was about to make, so the operator's normal finalization still runs.
Tests: tests/uninstall_test.yaml asserts that the hook is a pre-delete Job in the release namespace with a bounded runtime, that its RBAC is hook-scoped and grants exactly the verbs needed on every VictoriaMetrics kind the chart renders, that the binding targets the hook's ServiceAccount, that the script selects by release ownership, deletes, clears finalizers and exits 0, and that the VPA renders only when the capability is present (using capabilities.apiVersions). With the hook removed and vpa.yaml reverted, 6 of the 7 tests fail; with the fix, helm unittest packages/system/monitoring-agents passes 26/26.
hack/monitoring-agents-vm-cleanup-hook.bats runs the rendered script against a fake kubectl that keeps the objects in a state file, with fake date and sleep. It checks that only objects annotated for this release are deleted and patched, that with the operator gone the hook polls through the grace period and then clears the finalizers, that a live operator's objects are never patched, that a missing CRD still exits 0 and cleans the other kinds, and that a release with nothing left exits 0 without deleting anything. Removing the ownership condition, making the patch a no-op, or inverting the polling condition each turns this file red. The hook has not yet been run on a live tenant cluster.
Backport: labelled kind/backport (release-1.7). The release-1.6 backport is done by hand in #5158. The commit cherry-picks onto release-1.6 with a single trivial conflict in values.yaml (context only: 1.6 lacks the prometheus-node-exporter resources block the new kubectlImage block sits after on main). Resolved locally, the chart's tests pass on 1.6 (9/9); 1.6's chart renders the same VictoriaMetrics kinds. Note that release-1.6's monitoring-agents Makefile has no test: target, so CI does not run this chart's unit tests on that branch.

I walked the trigger map against the diff (a system chart's templates, values.yaml and tests): no package added or renamed, no platform values, no app schema, no CRD, no tooling or convention change. I also searched cozystack/website for a documented VMAgent finalizer workaround that this would make obsolete and found none.

fix(monitoring-agents): disabling the Monitoring Agents addon of a tenant Kubernetes cluster no longer leaves the monitoring-agents release stuck in UninstallFailed when the VictoriaMetrics operator is removed first; a pre-delete hook now releases the VictoriaMetrics objects' finalizers, and the VPA is only rendered when its CRD is served.
Summary by CodeRabbit
Bug Fixes
VictoriaMetrics resources belonging to a release are cleaned up during uninstall, including resources that remain because of finalizers. Cleanup is limited to resources owned by that release.
Vertical Pod Autoscaler resources are rendered only when the cluster supports the required API.
Configuration
Added an image setting for the uninstall cleanup job, including a pinned image version and pull policy.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
No actionable comments were generated in the recent review.
Walkthrough
The chart adds a VictoriaMetrics pre-delete cleanup hook with configured kubectl image settings. The hook selects and deletes release-owned objects, then polls and clears remaining finalizers. The VPA manifest renders only when Helm reports the VPA API as available. Tests cover both changes.
The chart configures the kubectl image, hook-scoped permissions, and pre-delete Job. Helm tests check the Job settings, permissions, binding, and cleanup command.
Find and remove release-owned objects packages/system/monitoring-agents/templates/vm-cleanup-hook.yaml, hack/monitoring-agents-vm-cleanup-hook.bats
The hook selects objects owned by the current release, requests deletion, polls for operator finalization, and clears finalizers if objects remain. Behavioral tests cover live and absent operators, missing CRDs, and no owned objects.
VPA API availability
Layer / File(s)
Summary
Gate VPA rendering on API availability packages/system/monitoring-agents/templates/vpa.yaml, packages/system/monitoring-agents/tests/uninstall_test.yaml
The VPA manifest renders only when Helm reports the API as available. Tests cover served and unavailable API cases.

mattia-eleuteri NOT LGTM. The cleanup needs an executable regression test, and the explanation needs correcting.
Please commit the stub-based checks described in the PR. The regex assertions in packages/system/monitoring-agents/tests/uninstall_test.yaml:100-124 do not check ownership protection, the finalizer fallback or the live operator's grace period. Evidence: removing the ownership condition, making the patch a no-op, or inverting the polling condition each leaves all 32 chart tests green; executing the rendered script against a recording kubectl stub fails the corresponding assertion.
The cleanup explanation overstates which objects hold the operator's finalizer. Evidence: the new hook header says "every one of these objects stays Terminating", but the shipped operator v0.68.4 adds its finalizer to VMAgent, not VMRule or the three scrape kinds. Please narrow that claim to VMAgent and remove the stale PR-body claim that every call has --request-timeout, which the second commit removed.
The first commit's body also needs to explain the reason rather than walk through the implementation, as required by docs/agents/contributing.md. Evidence: its second and third paragraphs begin "A pre-delete hook now deletes..." and "The VPA is also rendered...". Keep the root-cause explanation and drop the implementation walkthrough.

Account for sleep duration in a separate deadline test.
If sleep 2 changes to sleep 600, the test can pass while the Job expires before patching finalizers. Advance the clock for sleep in a separate test and check the first patch against the Job deadline.

Cover API time and patch completion in the deadline test.
The test measures time only from the first date call to before the first patch. API calls before that point and later patches also consume the Job deadline.
Add a case with bounded simulated API latency. Measure from simulated Job start and check that all owned objects are cleaned before the rendered deadline.

mattia-eleuteri NOT LGTM. Please add the missing ownership case and fix the remaining text.
The ownership test needs to cover both annotations that the PR uses to identify a release. Evidence: removing only && [ "$rns" = "$relns" ] leaves all six Bats tests green, while the rendered script then deletes a foreign object with the same release name and another release namespace. The current hook checks both annotations correctly. Please add the negative fixture and make the remaining-object assertion check the full annotation pair too.
Please remove the implementation walkthroughs from the commit bodies. Evidence: the first fix still has paragraphs starting "A pre-delete hook now deletes..." and "The VPA is also rendered...". The clock-test messages also contain "The fake date now logs each value it returns..." and "A separate test now charges each sleep to the fake clock...". Keep the reasons for those changes.
Please remove the model bylines from your timing-thread replies. Evidence: both still end with "Addressed by Claude Code", which docs/agents/contributing.md disallows.
…trics operator is gone first
Disabling the Monitoring Agents addon of a tenant cluster removes this
release, the VictoriaMetrics operator and the VPA CRDs together, and
Flux deletes them in parallel without honouring dependsOn. When the
operator goes first, nothing clears apps.victoriametrics.com/finalizer
on the VMAgent and the other VictoriaMetrics objects this chart created,
so they stay Terminating and the release sits in UninstallFailed for
good.
Clearing those finalizers has to happen inside the uninstall and must
never be what blocks it, and a live operator still has to get the first
chance to finalize its objects. Only objects of this release may be
touched, and release names are unique only within a namespace, so the
release name alone does not identify them. kubectl loads in-cluster
credentials only while the client config is otherwise default, which a
--request-timeout breaks. A VPA recorded in the release manifest while
its CRD is not served cannot be mapped at uninstall either.

mattia-eleuteri LGTM. Everything from my last review is fixed. I merged the head with current main and the monitoring-agents unit tests, the Bats suite and its cozytest run pass. Dropping only the release-namespace check still fails the ownership test.
One thing in the commit message, not blocking: it says the finalizer stays "on the VMAgent and the other VictoriaMetrics objects this chart created". In operator v0.68.4, which this chart ships, only the VMAgent controller adds apps.victoriametrics.com/finalizer, and the VMRule and scrape controllers never do. The hook header and the PR body already get this right. If you push again for any other reason, please narrow the commit body to the VMAgent too.
