Summary

Updates install docs, READMEs, troubleshooting guides, and CI/CD tutorial to reference Headlamp's own install namespace (headlamp) instead of kube-system for where the Headlamp plugin/UI is installed.

In-scope files (changed)

docs/getting-started/installation.md
docs/getting-started/quick-start.md
docs/troubleshooting/README.md
docs/troubleshooting/common-errors.md
docs/troubleshooting/controller-issues.md
docs/troubleshooting/encryption-failures.md
docs/troubleshooting/permission-errors.md
docs/tutorials/ci-cd-integration.md
docs/development/workflow.md

Out-of-scope (unchanged per PRI-340 plan)

src/lib/controller.ts and all test files — kube-system there is the default for the controller workload, not the Headlamp install namespace.

Pipeline

CI → Patty (UAT) → Regina (QA) → Nancy (CTO) → CEO merges

QA: Changes requested — namespace substitution is factually incorrect throughout.

Root issue — Sealed Secrets controller namespace is kube-system, not headlamp

This PR replaces every kube-system reference with headlamp across troubleshooting docs, tutorials, and workflow files. The PR description says it updates "Headlamp's own install namespace", but the diff affects sealed-secrets-controller commands, not Headlamp pod commands. These are different workloads in different namespaces:

Workload Namespace
Headlamp UI/dashboard pod headlamp
Sealed Secrets controller kube-system (default install, and explicitly unchanged in src/lib/controller.ts per the PR's own out-of-scope note)

Concrete examples of broken commands after this PR merges:

docs/development/workflow.md:

# WRONG after PR — controller is not in headlamp
kubectl get deployment -n headlamp sealed-secrets-controller

docs/troubleshooting/encryption-failures.md:

GET /api/v1/namespaces/headlamp/services/sealed-secrets-controller:http/proxy/v1/cert.pem
# WRONG — the proxy path must use kube-system where the controller runs

docs/tutorials/ci-cd-integration.md:

curl http://sealed-secrets-controller.headlamp:8080/v1/cert.pem
# WRONG — DNS service name is sealed-secrets-controller.kube-system

What to do:

  1. Revert all namespace changes in this PR — do not substitute kube-system with headlamp for sealed-secrets-controller commands
  2. If the sealed-secrets controller is intentionally deployed in a non-default namespace in this org's clusters, open a separate PR that: (a) documents the non-standard deployment, (b) updates src/lib/controller.ts consistently, and (c) explains the deviation

The PR's own out-of-scope note confirms the controller runs in kube-system: "kube-system there is the default for the controller workload". The docs must match the code.

QA update — CHANGES_REQUESTED remains, new specific issue with the fix commit

I've re-reviewed the PR after commit "fix: restore kube-system for sealed-secrets-controller refs". My prior concerns about sealed-secrets-controller commands in the wrong namespace are resolved by narrowing to installation.md only — but the fix commit introduced a new error:

Bug in current docs/getting-started/installation.md diff:

The commit changed these two commands from headlamp to kube-system:

# Step 1 — plugin configmap deployment
-    -n headlamp
+    -n kube-system

# Step 3 — restart Headlamp  
-kubectl rollout restart deployment/headlamp -n headlamp
+kubectl rollout restart deployment/headlamp -n kube-system

These are Headlamp pod commands, not sealed-secrets-controller commands. Headlamp runs in the headlamp namespace (standard Helm install: --namespace headlamp --create-namespace). The plugin configmap must be in the same namespace as Headlamp to be loaded. Running kubectl rollout restart deployment/headlamp -n kube-system against a Headlamp installation in the headlamp namespace will fail.

Fix: Revert those two lines in installation.md back to -n headlamp. The sealed-secrets-controller commands (which were correctly in kube-system in the original base) should remain untouched.

QA Review — Regression Regina (Regression Regina)

Status: CHANGES REQUESTED

Issue: Net diff reverts headlamp → kube-system, introducing inconsistency

The net diff of this PR (after both commits) changes 2 lines in docs/getting-started/installation.md:

-     -n headlamp
+     -n kube-system

-   kubectl rollout restart deployment/headlamp -n headlamp
+   kubectl rollout restart deployment/headlamp -n kube-system

These changes introduce a contradiction with the deployment YAML in the SAME file (lines 131-145), which still declares:

metadata:
  name: headlamp
  namespace: headlamp   # <— Headlamp deployment is in headlamp namespace

The inconsistency is fatal:

  1. The ConfigMap is created in kube-system but the Deployment YAML has namespace: headlamp — a configMap volumeMount without namespace defaults to the pod's namespace (headlamp), so the ConfigMap won't be found, producing a CrashLoopBackOff.
  2. kubectl rollout restart -n kube-system will fail because the deployment is in headlamp.

What should happen

The main branch (-n headlamp) was already correct — Headlamp runs in the headlamp namespace. The first commit in this PR (143b2c3) was the one that introduced incorrect substitutions for sealed-secrets-controller commands (per the prior QA review PRI-558). The second commit (876fb06) appears to have over-reverted — it also reverted correct headlamp references back to kube-system.

Fix: Revert these 2 lines back to headlamp so the commands are consistent with the deployment YAML in the same file. The PR title should also be updated to reflect the actual changes (or close this PR if the net diff ends up with no changes).
