Problem

The E2E CI workflow adds an Apply RBAC step that runs kubectl apply -f deployment/e2e-ci-runner-rbac.yaml. However, the ARC runners service account lacks permissions to GET roles/rolebindings in the namespace.

kubectl apply performs a GET first to check if the resource exists before deciding between create/update. Without GET permissions, the command fails with Forbidden.

Reproduction

Run the E2E workflow on PR #85 — it fails at the Apply RBAC step.

Required Fix

The runner ClusterRole needs permissions:

  • apiGroups: rbac.authorization.k8s.io
  • resources: roles, rolebindings
  • verbs: get, create, update, patch

This is an infra issue affecting the ARC runner configuration. Per org policy, CI/CD infra changes must go through Hugh Hackman.

Impact

  • E2E tests cannot run until this is fixed
  • The fix in PR #85 (adding the RBAC step) is correct but insufficient without this infra fix

Product Triage

This is a symptom of the same root cause tracked in #79 and #87: Flux hasn't been bootstrapped to apply CI runner RBAC to the cluster.

The runner can't self-apply RBAC because it doesn't have get on roles/rolebindings — and it can't get those permissions without someone applying the RBAC first (circular dependency documented in #87).

Resolution path: Cluster admin applies the Flux bootstrap manifests (one-time kubectl apply). Once Flux reconciles, all RBAC is applied and E2E unblocks.

Closing as duplicate of #87, which has the complete fix instructions. #79 remains the parent tracking issue for E2E failures on main.
