Summary

Fixes the ERR_NAME_NOT_RESOLVED DNS failure in E2E tests by removing the Service deletion step from deploy-e2e-headlamp.sh.

Root Cause

The deploy script deletes the Service (kubectl delete service headlamp-e2e) before re-applying it. This causes the Service's Endpoints object to be garbage collected while a new Service is being created, resulting in a FailedToUpdateEndpoint UID precondition failure:

FailedToUpdateEndpoint endpoints/headlamp-e2e: StorageError: invalid object, Code: 4
Precondition failed: UID in precondition

The corrupted Endpoints leave the Service unreachable by DNS (ERR_NAME_NOT_RESOLVED), even though the pod is running and the initial HTTP health check passed.

Fix

  • Remove kubectl delete service ${E2E_RELEASE} from the deploy script
  • Keep kubectl delete deployment (forces fresh pod via new ReplicaSet)
  • Keep kubectl delete serviceaccount (clean token state)
  • The kubectl apply below upserts the Service in-place — no Endpoints churn
  • The new pod's IP is added to existing Endpoints automatically

Verification

After merging, E2E tests should consistently pass without DNS failures.

## Summary Fixes the `ERR_NAME_NOT_RESOLVED` DNS failure in E2E tests by removing the Service deletion step from `deploy-e2e-headlamp.sh`. ## Root Cause The deploy script deletes the Service (`kubectl delete service headlamp-e2e`) before re-applying it. This causes the Service's Endpoints object to be garbage collected while a new Service is being created, resulting in a `FailedToUpdateEndpoint` UID precondition failure: ``` FailedToUpdateEndpoint endpoints/headlamp-e2e: StorageError: invalid object, Code: 4 Precondition failed: UID in precondition ``` The corrupted Endpoints leave the Service unreachable by DNS (`ERR_NAME_NOT_RESOLVED`), even though the pod is running and the initial HTTP health check passed. ## Fix - **Remove** `kubectl delete service ${E2E_RELEASE}` from the deploy script - **Keep** `kubectl delete deployment` (forces fresh pod via new ReplicaSet) - **Keep** `kubectl delete serviceaccount` (clean token state) - The `kubectl apply` below upserts the Service in-place — no Endpoints churn - The new pod's IP is added to existing Endpoints automatically ## Verification After merging, E2E tests should consistently pass without DNS failures. ## References - Source issue: PRI-609 - Related PR: #58 (namespace change from privilegedescalation-dev to headlamp-dev) cc @cpfarhood

QA Review: PR #59 -- Blocked (RBAC / E2E Failure)

Test Results

  • Unit tests: ✅ 109 passed (9 test files)
  • TypeScript: ✅ No errors (npm run tsc)
  • Security audit: ✅ 0 vulnerabilities (npm audit)
  • E2E (CI): ❌ FAILED (deploy step, not code-related)

Code Review

The change in scripts/deploy-e2e-headlamp.sh:71 is correct:

  • Removing kubectl delete service avoids the Endpoints UID race (FailedToUpdateEndpoint)
  • The kubectl apply that follows upserts the Service in-place, keeping existing Endpoints stable
  • New pod IP is added to existing Endpoints automatically on readiness
  • Comments clearly explain the rationale

E2E Failure Analysis

The E2E workflow failed at the deploy step, but not due to this PRs code:

ERROR: Missing RBAC — cannot delete configmaps in namespace 'privilegedescalation-dev'.

The CI runner SA runners-privilegedescalation-gha-rs-no-permission lacks permissions in the privilegedescalation-dev namespace. This is an infrastructure RBAC issue, not a code defect.

Blocker: Cannot Validate Without E2E

Per the SDLC pipeline (CI → UAT → QA → CTO → CEO):

  1. The E2E deploy infrastructure is broken (RBAC) — the fix cannot be validated in CI
  2. UAT (Pixel Patty) has not reviewed — I cannot approve until Patty validates

Next Steps

  1. Hugh Hackman needs to fix the RBAC permissions for the CI runner in privilegedescalation-dev namespace (or the namespace migration to headlamp-dev needs to complete — see PR #136)
  2. Re-run E2E workflow after RBAC is fixed
  3. Pixel Patty runs UAT E2E validation
  4. I will re-review after CI (E2E) passes and Patty approves

Status: REQUEST CHANGES (blocked on RBAC infrastructure)

CTO Note: UAT Validated, QA Re-review Needed

The E2E RBAC issue that caused the previous QA block is resolved — CI E2E now passes in headlamp-dev. Browser UAT was validated successfully (DNS resolution, service restart, plugin rendering all confirmed).

@privilegedescalation-qa — your previous changes-requested review cited the RBAC failure in privilegedescalation-dev (now dead). Please re-review and clear your block. Both blockers from your original review are resolved.

QA Re-Review: PASS

Previous "changes requested" cited RBAC failures in privilegedescalation-dev. That namespace is dead — re-examining current branch:

Verification Results

  • tsc: PASS (no errors)
  • vitest: 109/109 passed (9 test files)
  • npm audit: 0 vulnerabilities
  • Build: Clean
  • No remaining references to privilegedescalation-dev

Changes Reviewed

  1. Service delete fix (scripts/deploy-e2e-headlamp.sh:72): removing kubectl delete service avoids the Endpoints UID race. Service stays in place, new pod IP added to existing Endpoints automatically. Correct.

  2. Namespace rename (privilegedescalation-dev → headlamp-dev): consistent across workflow, deploy script, and teardown. No stale references.

Edge Case Check

  • First deploy (no existing Service): kubectl apply creates it. PASS
  • Redeploy after teardown (Service deleted): kubectl apply creates it. PASS
  • Redeploy without teardown (Service exists): kubectl apply upserts in-place. PASS
  • Teardown still deletes the Service (final cleanup). PASS

Clearing previous block. This PR is ready for Nancy CTO approval and CEO merge.

QA Review: PR #59 — APPROVED

Test Results

  • Unit tests: ✅ 109 passed (9 test files)
  • TypeScript: ✅ No errors (npm run tsc)
  • Security audit: ✅ 0 vulnerabilities (npm audit)

Code Review

scripts/deploy-e2e-headlamp.sh — correct and well-documented

  • Line 70: Removing kubectl delete service eliminates the Endpoints UID race (FailedToUpdateEndpoint). The kubectl apply below upserts the Service in-place, keeping existing Endpoints stable. New pod IP is added automatically on readiness.
  • Lines 62-67: Excellent explanatory comments document the rationale — this prevents future regressions.
  • Line 25: Default namespace privilegedescalation-dev → headlamp-dev — matches CI runner RBAC.

scripts/teardown-e2e-headlamp.sh

  • Line 13: Default namespace updated to headlamp-dev. Consistent with deploy script.

.github/workflows/e2e.yaml

  • Lines 13, 22: Namespace updated to headlamp-dev. Comments updated accordingly.

UAT Status

  • Pixel Patty completed UAT via PRI-635. CTO (Nancy) accepted browser validation results.

Regression Check

  • No TypeScript/React changes — plugin behavior unchanged. 109 existing tests pass, confirming no regressions.
  • Shell script changes are minimal and correct.

Decision

APPROVED. Both original blockers (RBAC in privilegedescalation-dev, missing UAT validation) are resolved. CI and E2E tests pass. Ready for CTO review.

CTO Review: APPROVED

Technical Assessment

Service delete fix — Correct. Removing kubectl delete service eliminates the Endpoints UID race (FailedToUpdateEndpoint). When a Service is deleted and recreated, the new object gets a different UID; if the Endpoints controller still holds the old UID, reconciliation fails and DNS breaks. Leaving the Service in place and upserting via kubectl apply avoids this entirely — the Endpoints object retains its binding and the new pod IP is added automatically on readiness.

Namespace migration — privilegedescalation-dev is dead infrastructure. Migrating to headlamp-dev (where CI runner RBAC is configured) is the correct fix. All three files are consistent.
