Closes: KATA-5833

- Description of the problem which is fixed/What is the use case
OSC operator currently requires TechPreview feature gate (SingleOwnNamespaceInstallSupport,
Alpha upstream) to support OLM v1 via config.inline.watchNamespace. This blocks
production OLM v1 deployments. Additionally, the operator is ineligible for OCP's
platform OLM v0→v1 migration tool (still in planning, mostly for 5.x).

This PR removes the TechPreview blocker by adding AllNamespaces support (Phase 2 of
migration strategy), enabling production-safe OLM v1 deployments without Alpha features.

- How to verify it

  1. Apply https://github.com/confidential-devhub/charts/tree/main/charts/osc-operator manifests to cluster with OLM v1 as provided in README.md
  2. Verify ClusterExtension installs without TechPreview gate
  3. Confirm operator pod running and KataConfig reconciliation works

- Description for the changelog
TBD

📝 Walkthrough

Walkthrough

The CSV manifests now mark AllNamespaces as supported. The bundle CSV creation timestamp also changes. New OLM documentation describes installation on OCP 4.22+, installation verification, KataConfig setup, uninstall, and phased migration from OLM v0.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to c22db

Following the installation guide alone may leave KataConfig reconciliation incomplete and can unexpectedly reboot workers. Correct the example or document its prerequisites, and warn about the reboot before merging.

OLMv1 will only support AllNamespaces Install mode. So this will become a hard requirement when we start migrating olmv0 -> olmv1.

OLMv1 will only support AllNamespaces Install mode. So this will become a hard requirement when we start migrating olmv0 -> olmv1.

True but my question was more if we should change the operator code. Claude shed some light :


The operator is architecturally cluster-scoped in every dimension:

  1. Manager setup (cmd/manager/main.go:141-175): No top-level Namespace or Namespaces restriction. The manager watches all namespaces by default. The only cache narrowing is per-object — Secrets and ConfigMaps
    are cached in just 2 namespaces each for memory efficiency, while Pods and everything else are cluster-wide.
  2. KataConfig is a cluster-scoped CRD (api/v1/kataconfig_types.go:74): marked +kubebuilder:resource:scope=Cluster. There's no namespace in its NamespacedName.
  3. All four controllers use cluster-wide watches with application-level filters (hardcoded namespace names, specific resource names), not OLM-provided namespace restrictions:
    • KataConfigOpenShiftReconciler watches Nodes, MCPs, ConfigMaps, Secrets — all cluster-wide, filtered by hardcoded names like OperatorNamespace
    • SecretReconciler filters to cco-secret in the operator namespace by name
    • RuntimeClassReconciler watches cluster-scoped RuntimeClasses and lists Pods cluster-wide
    • OscMetricsCollector lists Pods and KataConfig cluster-wide

So the reason "no code changes needed" is: the operator never relied on OLM's namespace scoping to begin with. The OwnNamespace/SingleNamespace install modes in the CSV were artificially restrictive — the
controllers already assume cluster-wide access. Flipping AllNamespaces: true simply makes the CSV match the operator's actual runtime behavior.


@thejasn please mention that no code change is needed like explained in claude's last sentence.

Yes, I agree with the conclusion. This change converges the CSV with the current architecture/design of the operator.

Some more findings from claude on the update :


  1. README.md line 17 says "Apply all OLM v1 manifests from the repo:" but the commands below install via Helm, not by applying manifests from this repo. This is leftover text from when the instructions
    referenced config/olmv1/. Should say something like "Install using the OSC Helm chart:".
  2. README.md line 59 — minor grammar: "If you are installing an older version that only supports OwnNamespace/SingleNamespace modes, needs config.inline.watchNamespace." Missing subject — should be "...modes,
    it needs..." or rewritten as "...modes, you need to set config.inline.watchNamespace."
  3. MIGRATION.md lines 58-62 — Phase 2 Option B still says "In progress" with a checkmark, and describes the change in future tense ("The only change is flipping..."). Since this PR is that change, the text
    should reflect it as done or present-tense.
  4. MIGRATION.md line 75 — "OSC is currently ineligible" is no longer true after this PR adds AllNamespaces support. Should be updated to reflect that OSC becomes eligible with 1.14.x.
