SPLAT-2899: support per-component credential overrides in openshift-config - #1075
SPLAT-2899: support per-component credential overrides in openshift-config#1075rvanderp3 wants to merge 2 commits into
Conversation
Allow administrators to provide per-component vSphere credentials by
placing override secrets in the openshift-config namespace. Override
secrets are mapped to their target CredentialsRequest via annotations:
cloudcredential.openshift.io/target-secret-namespace: <namespace>
cloudcredential.openshift.io/target-secret-name: <secret-name>
When a CredentialsRequest is processed, the actuator lists secrets in
openshift-config and looks for one whose target annotations match the
CredentialsRequest's spec.secretRef. If found, the override secret's
data is used; otherwise the shared root credential in
kube-system/vsphere-creds is used as a fallback.
This enables least-privilege, per-component credentials for vSphere
without breaking backward compatibility: clusters without override
secrets continue to work exactly as before, with all components
receiving the shared root credential.
Override secret example:
apiVersion: v1
kind: Secret
metadata:
name: anything-admin-wants
namespace: openshift-config
annotations:
cloudcredential.openshift.io/target-secret-namespace: openshift-machine-api
cloudcredential.openshift.io/target-secret-name: vsphere-cloud-credentials
cloudcredential.openshift.io/mode: passthrough
data:
<vcenter>.username: ...
<vcenter>.password: ...
Override secrets must carry the cloudcredential.openshift.io/mode
annotation (same as the root credential secret) to be accepted.
The credentials request controller is also updated to watch for
override secret changes in openshift-config so that create/update/delete
events trigger reconciliation of all CredentialsRequests.

Add test coverage for the vSphere per-component credential override feature introduced in the parent commit: - TestIsVSphereOverrideSecret (8 cases): exercises the pure function that identifies override secrets by namespace and annotations, covering correct matches, wrong namespace, nil/empty/partial annotations, and extra annotations. - TestCredentialsRequestVSphereReconcileWithOverride (5 cases): exercises the full controller reconcile path with override secrets, covering new CR provisioning with override data, updating stale targets when an override appears, fallback to root when the override targets a different CR, error when the mode annotation is missing, and provisioning with an override when no root secret exists.

WalkthroughThe change adds annotated per-component vSphere credential override support. The operator watches matching Secrets, selects overrides for CredentialsRequests, falls back to shared root credentials, and validates these paths with unit and reconciliation tests. ChangesvSphere credential overrides
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to This PR changes how vSphere component credentials are selected and reconciled. As written, changing or retargeting an override can leave stale credentials in use, while duplicate overrides can cause an unintended credential set to be selected, potentially misconfiguring components or weakening credential isolation. These issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Requeue when an override stops matching.
Line 241 checks only e.ObjectNew. If an update removes a target annotation, or changes the target to another CredentialsRequest, this predicate returns false. The prior target Secret then keeps the old override data until its next periodic reconciliation.
Check both versions during updates.
Proposed fix
UpdateFunc: func(e event.TypedUpdateEvent[*corev1.Secret]) bool {
- return IsVSphereOverrideSecret(e.ObjectNew.GetNamespace(), e.ObjectNew.GetAnnotations())

Handle the provider-spec encoding error.
Line 359 discards the error from minterv1.Codec.EncodeProviderSpec. If encoding fails, this helper creates an invalid CredentialsRequest and hides the cause from the test.

Reject duplicate vSphere override targets.
When two Secrets in openshift-config have the same target annotations, GetCredentialsRootSecret returns the first match. Different override data can therefore supply unintended credentials. No repository validation enforces unique target annotations. Reject duplicate matches with CredentialsProvisionFailure and add a test with two matching overrides.
