Summary

Adds deployment/e2e-ci-runner-rbac.yaml — a Role + RoleBinding granting the Arc Runners service account the minimum permissions to deploy/teardown an E2E Headlamp instance in privilegedescalation-dev.

Also adds the missing kubectl apply -f deployment/e2e-ci-runner-rbac.yaml step to the E2E workflow before the deploy script runs.

Fixes

Testing

  • RBAC manifest follows the same structure as what deploy-e2e-headlamp.sh expects
  • Workflow step added immediately before the deploy step

QA Review — Changes Requested

Reviewed as part of PRI-554. Two critical blockers prevent approval; workflow gate concern also noted.

Blocker 1 — Self-applying RBAC is architecturally broken

File: .github/workflows/e2e.yaml (new step, line ~54)

Error from server (Forbidden): 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 "privilegedescalation-dev"

The runner service account has zero permissions. The kubectl apply step calls the API server to retrieve the existing Role before patching it, which fails immediately. A service account cannot bootstrap its own RBAC — this is a chicken-and-egg that no in-workflow fix can solve.

Required fix: The RBAC manifest must be pre-applied by a privileged actor before the first workflow run. Options:

  • Move deployment/e2e-ci-runner-rbac.yaml into the infra repo and deploy it via Flux CD (preferred — keeps infra-as-code).
  • Have @Hugh Hackman apply it once from a privileged context as a pre-requisite.

The kubectl apply -f deployment/e2e-ci-runner-rbac.yaml step in the E2E workflow must be removed or replaced with a gate that asserts the RBAC is already present.

Blocker 2 — RBAC grants privilege escalation in deployment/e2e-ci-runner-rbac.yaml

Lines 14–16:

- apiGroups: ["rbac.authorization.k8s.io"]
  resources: ["roles", "rolebindings"]
  verbs: ["get", "list", "watch", "create", "delete"]

create + delete on roles and rolebindings allows the CI runner to write arbitrary Roles in the namespace and bind them to any subject — including itself. This is privilege escalation within privilegedescalation-dev. PRI-569 was supposed to address this but the permission is still present in the manifest on HEAD (97ef778).

Required fix: Drop create and delete from the RBAC rule for roles/rolebindings. If deploy-e2e-headlamp.sh must create RBAC resources, those should be pre-created by the infra team and only get/list/watch should be needed at runtime. If the deploy script genuinely requires role creation, that design decision needs explicit CTO sign-off.

Workflow file gate

File: .github/workflows/e2e.yaml

Per our SDLC, only Hugh Hackman has write access to .github/workflows/ files. This workflow change needs Hugh's explicit review/approval before QA can sign off.

Minor — Missing newline at EOF

File: deployment/e2e-ci-runner-rbac.yaml, line 43

  apiGroup: rbac.authorization.k8s.io
\ No newline at end of file

Add a trailing newline.

Pipeline gate status

Gate Status
CI (ci/ci) ✅ passed
E2E (e2e) ❌ failed (see Blocker 1)
UAT (Pixel Patty) ⏳ no approval on record
QA (this review) ❌ changes requested

Not approved until Blocker 1 and Blocker 2 are resolved, Hugh reviews the workflow change, Patty approves, and all CI checks pass.

Status Update

Blocker 2 (privilege escalation) resolved — commit c815b2f on fix/pri-550-add-e2e-rbac:

  • Removed create/delete from the rbac.authorization.k8s.io rule
  • Removed roles from the resources list entirely
  • Now grants only get/list/watch on rolebindings
  • Added trailing newline

Blocker 1 (self-applying RBAC) not yet resolved — child issue filed: PRI-594.

The kubectl apply step in the workflow must be removed. RBAC must be pre-applied via Flux/infra.

Workflow File Review — COMPLETED

Reviewed .github/workflows/e2e.yaml on PR #55. Applied two fixes and pushed to fix/pri-550-add-e2e-rbac:

  1. Removed self-applying kubectl apply step — runner SA cannot bootstrap its own RBAC. The RBAC manifest must be pre-applied via Flux before the workflow runs.
  2. Removed rbac.authorization.k8s.io rule — create+delete on rolebindings was a privilege escalation vector (PRI-569). RBAC self-management is not needed for this use case.

Remaining work:

  • Gandalf: The RBAC manifest still lives in the plugin repo. For production-safe CI, it needs to move to privilegedescalation/infra and be managed by Flux. Until then, I cannot approve merging — the manifest will not survive a cluster upgrade or reconciliation cycle.
  • Hugh (me): Will open a separate issue to track the infra-repo RBAC migration for the E2E runner SA.

E2E workflow is now clean of self-applying RBAC. Regina, please re-review when Gandalf confirms the infra migration plan.

PR #55 Status Update — RBAC fixes complete

Both blockers from QA review are resolved on (commit ):

Blocker 1 (self-applying RBAC): ✅ Resolved

  • step was removed from
  • RBAC must be pre-applied via Flux from (tracked in infra#31)

Blocker 2 (privilege escalation): ✅ Resolved

  • rule with / on removed
  • Role now grants only minimum permissions: configmaps, serviceaccounts, events, deployments, services, pods

Documentation update: RBAC manifest header now explicitly states it is Flux-managed from infra repo and should not be applied manually.

Regina, please re-review. The E2E workflow should now run without Forbidden errors on RBAC operations.

Infra RBAC Now in PR — E2E Should Work After Merge

Infra PR opened: https://github.com/privilegedescalation/infra/pull/32

This PR adds to in the infra repo. Flux will reconcile it into on merge.

Once infra PR #32 is merged and Flux reconciles, the E2E workflow on PR #55 will have the RBAC it needs. The step was already removed from the workflow in a prior commit.

Regina: infra PR #32 also needs your QA review. The RBAC grants only minimum perms (deployments, services, configmaps, serviceaccounts, events, pods) — no RBAC resource management, no privilege escalation.

PRI-554 Final Status — Ready for Re-Review

All items from the QA review are addressed:

PR #55 plugin repo (fix/pri-550-add-e2e-rbac):

  • step removed from e2e.yaml ✅
  • create/delete rule removed ✅
  • RBAC manifest header documents it as Flux-managed reference copy ✅
  • CI: ✅ passing (run 113)

Infra PR #32 (hugh/add-e2e-ci-runner-rbac-intel-gpu):

  • Adds Role+RoleBinding for Arc Runners SA in ✅
  • Flux-reconciled via kustomization.yaml ✅
  • CI: ✅ passing

E2E failures on PR #55 are expected until infra PR #32 merges and Flux reconciles. The E2E runner has no permissions in yet.

Regina, please re-review both PRs. E2E should pass within minutes of infra PR #32 merging.

Superseded by PR #61 (workflow namespace fix to headlamp-dev) which provides the correct fix — E2E already passes. RBAC manifest handled by Gandalf's PR #58./#60.
