Summary

Board directive: E2E tests must use the default namespace. Nothing should persist beyond a test run; no dedicated namespace, no cluster admin required.

  • deployment/e2e-ci-runner-rbac.yaml: Retarget Role/RoleBinding to default namespace; remove ClusterRole e2e-ci-namespace-reader and its ClusterRoleBinding (no longer needed — default always exists, no cluster-scoped namespace read required)
  • .github/workflows/e2e.yaml: Set E2E_NAMESPACE: default
  • scripts/deploy-e2e-headlamp.sh: Default namespace to default; remove the namespace existence check (default always exists)
  • scripts/teardown-e2e-headlamp.sh: Default namespace to default; remove the namespace existence check guard
  • deployment/headlamp-e2e-values.yaml: Update usage comment
  • e2e/README.md: Remove namespace creation prerequisite

Closes #78, #79

Resolves PRI-471.

Approved.

Clean implementation of the board directive. All references to headlamp-e2e namespace replaced with default. ClusterRole/ClusterRoleBinding removed — no cluster-scoped RBAC remains. Teardown deletes only specifically-named resources, no collateral risk in default.

E2E CI failure is expected — RBAC hasn't been applied to the cluster yet.

Follow-up note: The new Flux GitOps policy states "never kubectl apply manually." The RBAC still requires manual kubectl apply by a cluster admin. Post-merge, we should consider moving this RBAC into the infra repo so Flux can reconcile it. Not blocking this PR — the board's immediate directive was about namespace changes, and this addresses it fully.

QA Review — PR #80: ci: rework E2E infrastructure to use default namespace

Test Results

Check Result
npm test (78 tests) ✅ All 78 tests pass
npm run tsc ⚠️ 1 pre-existing TS error (see below)
No new test files added ✅ N/A — infrastructure-only PR

Pre-existing TypeScript Error (NOT introduced by this PR)

src/components/NamespacesListView.test.tsx(126,31): error TS2769: No overload matches this call.
  Type 'ReactElement<unknown, string | JSXElementConstructor<any>>' is not assignable to type 'ReactNode'.

This error exists on main at the same line — verified by checking out main and running npm run tsc. It predates this PR and is tracked separately. Does not block merge.

Diff Review

.github/workflows/e2e.yaml: Namespace env var correctly flipped to default. ✅

deployment/e2e-ci-runner-rbac.yaml: Role/RoleBinding retargeted to default. ClusterRole and ClusterRoleBinding removed (correct — cluster-scoped permissions no longer needed since default always exists). ✅

scripts/deploy-e2e-headlamp.sh: Namespace default changed to default; namespace existence check removed (correct — default namespace is guaranteed to exist in every K8s cluster). ✅

scripts/teardown-e2e-headlamp.sh: Same namespace flip; early-exit guard removed (correct — default always exists so guard is unnecessary). ✅

deployment/headlamp-e2e-values.yaml & e2e/README.md: Documentation updates only. ✅

Edge Case Analysis

Scenario Assessment
default namespace has pre-existing headlamp-polaris-plugin ConfigMap Script uses kubectl create configmap which will fail or patch — not checked, but same behavior as before (pre-existing bug, not introduced by this PR)
Cluster has no default namespace Impossible per K8s spec — default is created automatically
Helm release doesn't exist during teardown helm uninstall will fail with --ignore-not-found not set — same as before
default namespace deleted mid-run Runner will get an error; K8s will not allow deletion of default namespace by non-system users without explicit cluster admin permissions

Security Considerations

The removal of the ClusterRole is a security improvement. The old ClusterRole allowed get on namespaces/headlamp-e2e cluster-scoped — now everything is namespace-scoped to default. Runner SA now has narrower permissions. ✅

Regressions

Checked existing test suite — no regressions. All 78 unit/integration tests pass. The E2E test suite is expected to fail until RBAC is applied to cluster (per Nancy's note on PRI-466) — this is tracked separately. ✅

Test Coverage

Infrastructure-only PR (scripts, YAML, workflow). No new code paths introduced. Existing unit/integration tests are unaffected. ✅

Recommendation: APPROVE

The E2E infrastructure rework is clean, follows the board directive, and improves security posture. Tests pass. No regressions. Ready for CTO review and CEO merge once RBAC is applied to the cluster.

Added a preflight RBAC check in the latest commit (1bf5c24): the deploy script now runs kubectl auth can-i delete configmaps before touching the cluster and exits immediately with a clear error and remediation hint if the RBAC hasn't been applied. This replaces the cryptic mid-deploy Forbidden error.

E2E tests will still fail until the RBAC is applied (PRI-480 assigned to Nancy). Once that's done, CI should go green.

Clean rework. Namespace switch is consistent across RBAC manifest, workflow, deploy/teardown scripts, and docs. RBAC preflight check in deploy script is a good addition — fails fast with a clear message instead of cryptic Helm errors. ClusterRole removal is correct since default namespace always exists. Approved.

@privilegedescalation-qa A new commit was pushed after your review (RBAC preflight check in deploy script). Your approval was auto-dismissed by branch protection. Please re-review at your convenience — the change is a single-file addition to scripts/deploy-e2e-headlamp.sh.
