OCPBUGS-120667: fix(gcp-pd): don't apply guest-cluster resources against the management cluster on HyperShift - #618
Conversation
…loop On HyperShift, PrerequisiteAssets are applied via the management-cluster client, which lacks permissions to create cluster-scoped RBAC (hostnetwork_role.yaml, node_sa.yaml, privileged_role.yaml, etc.). This caused the operator to fail applying prerequisites and crash-loop on startup. Make GetGCPPDOperatorConfig take an isHypershift flag and only include controller_sa.yaml in PrerequisiteAssets for HyperShift, since the remaining node/guest-cluster assets are already applied against the correct (guest) client via GuestConfig.Assets.

📝 WalkthroughWalkthroughThe GCP PD operator configuration factory now accepts a HyperShift mode flag. It always includes the controller service-account asset. It includes node service-account, host-network RBAC, and privileged node RBAC assets only for standalone clusters. The operator entry point passes the mode flag, and the prerequisite test updates its factory call. Suggested reviewers: Merge Risk: 🔵 Low · up to The PR prevents unnecessary HyperShift management-cluster RBAC application, but its test does not verify the standalone and HyperShift asset sets, so a regression could reintroduce the startup crash loop unnoticed. The change is mergeable with explicit owner follow-up to add those assertions. 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)

The changed code only selects prerequisite asset filenames based on HyperShift mode. Existing logs for infrastructure regions, labels, tags, and prerequisite errors are outside the changed lines; HyperShift now removes several prerequisite operations and therefore does not increase their logging exposure.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Add assertions for both prerequisite-asset modes.
This test uses opConfig.AssetDir, but it passes hard-coded asset lists to applyPrerequisites. It never checks opConfig.PrerequisiteAssets. It also never calls GetGCPPDOperatorConfig(true).
Add assertions that standalone returns all six assets and HyperShift returns only controller_sa.yaml. Otherwise, a regression that restores management-cluster RBAC assets in HyperShift will pass this test and can restore the Forbidden crash loop.

@rhrmo : Could you please help with this update as well? I had missed including these changes in my initial PR. While merging the HyperShift portion of the work, the HyperShift E2E CI tests caught this bug. I need this fix to go in for the HyperShift CI to succeed and for the HyperShift work to merge. I have re-verified the PV/PVC tests with all the changes across the relevant repositories (CSI, CSO, and HyperShift operators). Hopefully, this is the last one in this PR. |

Summary
Problem: On HyperShift, the operator applies
PrerequisiteAssetsusing the management-cluster client. Several of those assets are guest-cluster resources that shouldn't be applied to the management cluster at all.Fix:
GetGCPPDOperatorConfignow takes anisHypershiftflag. On HyperShift,PrerequisiteAssetsonly includescontroller_sa.yaml. Among the rest:hostnetwork_role.yaml/controller_hostnetwork_binding.yaml— not needed at all on HyperShift, since the controller pod runs withhostNetwork: falsethere.node_sa.yaml/privileged_role.yaml/node_privileged_binding.yaml— still needed, these guest-cluster resources are already applied correctly viaGuestConfig.Assets, so listing them here too was just duplicating.Standalone is unaffected (
isHypershift=falsekeeps the full list).Test plan
