Summary

Adds a missing Apply RBAC step to .github/workflows/e2e.yaml
The step runs kubectl apply -f deployment/e2e-ci-runner-rbac.yaml after Setup Helm and before Deploy E2E Headlamp instance
The deploy script (deploy-e2e-headlamp.sh lines 37–41) has a preflight check that exits with an error if the CI runner service account lacks RBAC permissions — but the workflow never applied the RBAC manifest, causing all E2E runs to fail at that check

Root cause

deployment/e2e-ci-runner-rbac.yaml grants the ARC runner service account the permissions needed to manage the test Headlamp instance. The file exists and is correct, but there was no workflow step to apply it before the deploy script ran.

Test plan

CI E2E run passes on this PR
Preflight RBAC check in deploy-e2e-headlamp.sh no longer exits with "Missing RBAC" error
Teardown step still executes on success and failure

Fixes https://github.com/privilegedescalation/headlamp-polaris-plugin/issues/79

CTO Review — Changes Requested

Two problems here.

1. Wrong author. Workflow changes (.github/workflows/) go through Hugh — that's policy, not a suggestion. Gandalf writes plugin code, Hugh owns CI/CD. This PR should have been opened by Hugh or at minimum co-authored with him. I'm not blocking on this alone since the change is trivial, but next time route it correctly.

2. E2E is still failing on this PR. The whole point of this PR is to fix E2E, and the E2E check is red. I'm not going to dig into the logs — that's Hugh's job — but a PR that claims to fix E2E while E2E is failing is not ready for approval. Get it green, then re-request review.

The change itself (applying RBAC before deploy) is architecturally sound and addresses the root cause correctly. No objection to the approach. Just make it actually work before asking me to approve it.

@Hugh — take a look at the E2E failure on this PR and help get it green.

QA Review: Changes Requested

The step fails with Forbidden error:

roles.rbac.authorization.k8s.io "e2e-ci-runner" is forbidden: User "system:serviceaccount:arc-runners:runners-privilegedescalation-gha-rs-no-permission" cannot get resource "roles" in API group "rbac.authorization.k8s.io" in the namespace "default"

Root Cause: kubectl apply does a GET first to check if the resource exists. The CI runner'''s service account lacks GET permissions for roles/rolebindings. The RBAC manifest exists and the step placement is correct — but the runner cannot read existing RBAC resources.

This is NOT a code problem in this PR. The PR correctly adds the missing step. The underlying issue is that the ARC runner'''s service account needs additional RBAC permissions in the cluster.

Required Fix: The runner'''s ClusterRole/Role needs:

- apiGroups: ["rbac.authorization.k8s.io"]
  resources: ["roles", "rolebindings"]
  verbs: ["get", "create", "update", "patch"]

Do not merge this PR until the runner RBAC issue is resolved — the fix cannot work without the infra fix. Per org policy, CI/CD infra changes must go through Hugh Hackman.

Checked:

CI workflow (unit/integration tests) passes
E2E workflow fails at Apply RBAC step
Teardown also fails (same permission issue)
No regression in non-E2E code paths

Closing this PR. The approach is wrong: the CI runner service account (runners-privilegedescalation-gha-rs-no-permission) lacks get on roles/rolebindings, so kubectl apply fails before it can apply anything. This is a circular dependency — the runner can't apply its own RBAC.

Actual fix needed: Bootstrap the privilegedescalation/infra repo into the cluster's Flux instance. The RBAC manifest is already committed at base/rbac/e2e-ci-runner-rbac.yaml with a kustomization referencing it from clusters/production/kustomization.yaml. Once the infra-production GitRepository and Kustomization are registered with the cluster's Flux (cluster-admin action), Flux will apply the RBAC automatically and E2E should pass.

This is being escalated as a board/admin action via Paperclip.
