Description

Part 2 of the OPRUN-4738 review split from PR #2938. This adds a standalone object-controller manager with a scheme limited to ClusterObjectSet and the Kubernetes types it needs. The manager reads referenced Secrets directly without a cluster-wide Secret informer. It also provides metrics, TLS, health checks, leader election, and a version command.

This PR adds the command and its integration coverage. The current operator-controller registration stays active. Packaging follows in PR #2948, and deployment and controller handoff follow in PR #2949.

This PR also corrects the test import left behind when shared labels moved in PR #2946.

Subtask: OPRUN-4773.

Validation: make verify, make lint, and make test-unit passed. Focused Go tests passed for cmd/object-controller, internal/object-controller/controllers, and internal/operator-controller/controllers.

Reviewer Checklist

📝 Walkthrough

Walkthrough

Adds the object-controller command, configures its manager and ClusterObjectSet reconciler, and registers the required runtime types. Tests cover command configuration, version output without a cluster, and standalone reconciliation with only the ClusterObjectSet CRD.

Changes

Object Controller

Layer / File(s)	Summary
Command configuration and validation `cmd/object-controller/main.go`, `cmd/object-controller/main_test.go`	Adds command flags and a version subcommand. Validates metrics TLS options and tests the validation rules.
Manager setup and standalone reconciliation `internal/object-controller/scheme/scheme.go`, `cmd/object-controller/main.go`, `cmd/object-controller/main_test.go`	Registers Kubernetes and ClusterObjectSet types, configures manager services and the reconciler, and tests version output and standalone reconciliation. The integration test checks rollout status, managed ConfigMap data and ownership, recreation after deletion, and ClusterObjectSet deletion.

Shared Labels Test Import

Layer / File(s)	Summary
Test labels import `internal/operator-controller/controllers/boxcutter_reconcile_steps_test.go`	Changes the test’s labels import to `internal/shared/labels`.

Merge Risk: ⚪ Minimal · up to c24eb

The previously reported test-build failure and branch-specific write-up are no longer present. No actionable merge-blocking issue is established.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 35cbe

The new controller has sensitive responsibilities, but its production permissions and handoff are deferred to a later change. The reviewed code includes controls for metrics access, Secret-read retries, and consistent reads within a reconciliation; no introduced security vulnerability was verified.

Retained concerns

Medium · security · inferred: The standalone controller delegates authorization for cross-namespace Secret references to its runtime Kubernetes identity. Its eventual service-account permissions are not established by this PR, so equivalent or appropriately limited authority cannot yet be verified.
Low · architecture · inferred: The new binary and the existing operator-controller both register the ClusterObjectSet reconciler. If deployed concurrently against the same objects, exclusive reconciliation is not demonstrated; the deployment and handoff are explicitly deferred.

Security review details

Security Blast Radius

inferred — A principal able to change ClusterObjectSets can select Secret references and object manifests; effective Secret and managed-object scope depends on the controller's Kubernetes permissions. The new binary's production identity and exposure remain unverified.

Security Findings and Attack Paths

inferred — No introduced exploit is verified. A cross-namespace reference reaches a direct Kubernetes API Secret read, but the existing controller already has a direct-read path for such Secrets; whether the standalone deployment changes effective authority depends on its future credentials and permissions.

Trust Boundaries and Controls

observed — Referenced Secrets must be immutable before use; decoded gzip content has a size limit, and later reconciliation checks resolved content against observed phases. Kubernetes API authorization, rather than a separate reference-specific check in this path, governs the read.

Resilience and Maintainability Implications

inferred — A replacement Secret is reread on the next reconciliation, but the inspected controller setup watches ClusterObjectSets and tracked managed objects, not Secrets. Detection after a Secret-only replacement therefore depends on another reconciliation trigger.

Hardening Proposals

proposed — Before deployment, verify the standalone service account's Secret-read and object-write permissions against intended namespace policy, and establish an explicit exclusive-ownership and rollback procedure for the controller handoff.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Requeue while referenced Secrets remain mutable.

When a ClusterObjectSet first reaches this branch, establishWatch has not run. SetupWithManager has no direct Secret watch. The branch also returns no error and no delayed requeue. After the status update causes its immediate follow-up reconcile, changing the Secret to immutable does not enqueue the ClusterObjectSet. It can remain Blocked until another ClusterObjectSet event occurs.

Return a delayed requeue while the Secret is mutable.
Suggested fix
 		l.Error(err, "referenced Secret verification failed, blocking reconciliation")
 		markAsNotProgressing(cos, ocv1.ClusterObjectSetReasonBlocked, err.Error())
-		return ctrl.Result{}, nil
+		return ctrl.Result{RequeueAfter: 10 * time.Second}, nil

I know this is pulled forward from the existing implementation, so non-blocking comment: I see no reason for the COS controller to read and react to annotations on COS objects.

Is it part of the overall plan to phase this out?

Yes, I'm working on OPRUN-4738, which is part of OCPSTRAT-3042

Add a dedicated object-controller command with a ClusterObjectSet-focused scheme. Configure direct Secret reads, metrics, TLS, health and readiness probes, leader election, and version output. Cover standalone reconciliation in an envtest integration test. Update the Boxcutter test to import the shared labels package.
