Per Phase 1 audit at cowork/docs-overhaul-phase-1-audit-2026-05-04/
and the section-by-section plan in testing-guide-tumor.md.
testing-guide.md was 30% of all docs/ content (8268 lines) but was
integration test code written in markdown, not operator documentation.
The audit's tumor analysis disposed of every Part:
- ~65% DELETE (test cases that already exist in code)
- ~22% MOVE to inline test code
- ~8% KEEP-COMPRESSED into focused operator-runbook docs
- Title + contents + release sign-off ~5% KEEP
This commit ships the KEEP-COMPRESSED dispersal:
docs/contributor/qa-prerequisites.md (NEW, ~120 lines):
From testing-guide.md "Prerequisites" section. Stack boot procedure,
demo data baseline, reference IDs operators reuse across QA docs.
docs/contributor/gui-qa-checklist.md (NEW, ~105 lines):
From testing-guide.md "Part 35: GUI Testing". Manual GUI verification
pass for release sign-off. 25-row table covering every dashboard page.
docs/contributor/release-sign-off.md (NEW, ~130 lines):
From testing-guide.md "Release Sign-Off" section (originally 1009
lines of per-test detail tables). Compressed to a release-day
checklist organized by gate category: code state, automated gates,
manual QA passes, release artefact verification, branch protection,
post-release.
docs/operator/performance-baselines.md (NEW, ~100 lines):
From testing-guide.md "Part 39: Performance Spot Checks". Four
operator-runnable benchmarks (API request handling, inventory list
pagination, scheduler tick, bulk revoke) with baseline numbers and
when-to-re-baseline guidance.
docs/operator/helm-deployment.md (NEW, ~120 lines):
From testing-guide.md "Part 52: Helm Chart Deployment". Operator
runbook for the bundled deploy/helm/certctl/ chart: prereqs,
install, four cert-source patterns, verify, upgrade, troubleshooting.
docs/reference/cli.md (NEW, ~120 lines):
From testing-guide.md "Part 28: CLI Tool". certctl-cli command
reference with command-group breakdown, common workflows
(list/filter, renew, revoke, bulk import, EST enrollment, status),
output formats, CI/CD integration patterns.
docs/README.md navigation index updated to include the 6 new docs:
Reference section gains: cli.md, release-verification.md (was added
in Phase 13)
Operator section gains: helm-deployment.md, performance-baselines.md
Contributor section gains: qa-prerequisites.md, gui-qa-checklist.md,
release-sign-off.md
docs/testing-guide.md deleted. Git history preserves the 8268 lines —
if any specific test case is found missing from inline test code or
the destination docs during future work, lift from `git show
HEAD~1:docs/testing-guide.md`.
Net: docs/ total line count drops by ~7700 lines (28%), from 26,369
to 18,742. testing-guide.md was the single largest doc; pruning it is
the single biggest content-edit win of the entire restructure.
Phase 5 is the last major content phase. Remaining: Phase 4 follow-on
(per-connector page extractions from reference/connectors/index.md),
Phase 15 (WHAT/HOW/WHY remediation), Phase 16 (final acceptance gate).

# Helm Deployment
|
|
|
|
> Last reviewed: 2026-05-05

|
|
Operator runbook for deploying certctl on Kubernetes via the bundled Helm chart at `deploy/helm/certctl/`.
|
|
|
|
## Prereqs
|
|
|
|
- Kubernetes cluster, v1.27+
|
|
- `kubectl` configured and authenticated
|
|
- `helm` v3.13+
|
|
- Storage class for the PostgreSQL StatefulSet PVC
|
|
- TLS cert source: either an operator-supplied `kubernetes.io/tls` Secret OR a cert-manager `ClusterIssuer` / `Issuer`. The chart refuses to render without one. See [`tls.md`](tls.md) for the four cert provisioning patterns.
|
|
|
|
## Install
|
|
|
|
```bash
|
|
helm install certctl deploy/helm/certctl/ \
|
|
--namespace certctl \
|
|
--create-namespace \
|
|
--set server.apiKey=$(openssl rand -hex 32) \
|
|
--set postgres.password=$(openssl rand -hex 32) \
|
|
--set server.tls.existingSecret=certctl-server-tls
|
|
```
|
|
|
|
`server.apiKey` and `postgres.password` should be high-entropy values. The example above generates them inline; production deployments use a secrets manager (Vault, External Secrets Operator, AWS Secrets Manager) instead.
|
|
|
|
## What you get
|
|
|
|
- **Server Deployment** with a configurable replica count (default 1; HA needs sticky sessions on the ACME server's nonce path)
|
|
- **PostgreSQL StatefulSet** with PVC-backed persistence
|
|
- **Agent DaemonSet** with one agent per node (configurable via `agent.daemonset.enabled=false` if you don't want the in-cluster agent)
|
|
- Health probes (`/health` liveness + `/ready` readiness)
|
|
- Security contexts: non-root, read-only root filesystem
|
|
- Optional Ingress (off by default; opt in via `ingress.enabled=true`)
|
|
|
|
## Cert source patterns
|
|
|
|
### Pattern 1 — operator-supplied Secret (recommended for non-cert-manager shops)
|
|
|
|
```bash
|
|
kubectl create secret tls certctl-server-tls \
|
|
--cert=server.crt --key=server.key \
|
|
--namespace certctl
|
|
|
|
helm install certctl deploy/helm/certctl/ \
|
|
--namespace certctl \
|
|
--set server.tls.existingSecret=certctl-server-tls
|
|
```
|
|
|
|
### Pattern 2 — cert-manager Certificate CR (recommended for cert-manager shops)
|
|
|
|
```bash
|
|
helm install certctl deploy/helm/certctl/ \
|
|
--namespace certctl \
|
|
--set server.tls.certManager.enabled=true \
|
|
--set server.tls.certManager.issuerRef.name=my-cluster-issuer \
|
|
--set server.tls.certManager.issuerRef.kind=ClusterIssuer
|
|
```
|
|
|
|
### Refuses to render without one of the above
|
|
|
|
```bash
|
|
helm install certctl deploy/helm/certctl/ --namespace certctl
|
|
# Error: server.tls.existingSecret OR server.tls.certManager.enabled must be set
|
|
```
|
|
|
|
The render-time guard catches the missing config at `helm install` time, not at pod-crash-loop time.
|
|
|
|
## Verify the install
|
|
|
|
```bash
|
|
kubectl wait --for=condition=Ready --timeout=3m \
|
|
-n certctl pod -l app.kubernetes.io/name=certctl-server
|
|
|
|
kubectl port-forward -n certctl svc/certctl-server 8443:8443 &
|
|
|
|
# Bundle the TLS root from the Secret to verify
|
|
kubectl get secret -n certctl certctl-server-tls -o jsonpath='{.data.ca\.crt}' \
|
|
| base64 -d > /tmp/certctl-ca.crt
|
|
curl --cacert /tmp/certctl-ca.crt https://localhost:8443/health
|
|
# {"status":"healthy"}
|
|
```
|
|
|
|
If the Secret has no `ca.crt` key (operator-supplied Secrets often don't), use `tls.crt` as the bundle. For a self-signed cert the two files are identical; for a chained cert distribute the root CA bundle separately via ConfigMap.
|
|
|
|
## Upgrade
|
|
|
|
```bash
|
|
helm upgrade certctl deploy/helm/certctl/ \
|
|
--namespace certctl \
|
|
--reuse-values
|
|
```
|
|
|
|
Postgres state survives the upgrade (the PVC is retained). The server / agent images bump per the chart's `image.tag`. See [`docs/archive/upgrades/`](../archive/upgrades/) for version-specific upgrade guidance.
|
|
|
|
## Configuration reference
|
|
|
|
Every value is documented at `deploy/helm/certctl/values.yaml`. Common tweaks:
|
|
|
|
- `server.replicaCount` — replica count (default 1)
|
|
- `server.resources.{requests,limits}` — pod resource bounds
|
|
- `agent.daemonset.enabled` — toggle the in-cluster agent (default true)
|
|
- `postgres.storageSize` — PVC size (default 10Gi)
|
|
- `ingress.enabled` + `ingress.host` — opt into Ingress
|
|
|
|
## Troubleshooting
|
|
|
|
**Pod crash-loops with TLS error.** Cert + key in the Secret don't pair. Verify with `openssl x509 -modulus -in server.crt -noout | md5` against `openssl rsa -modulus -in server.key -noout | md5` — outputs must match.
|
|
|
|
**Agent DaemonSet pods can't reach the server.** Service DNS / NetworkPolicy issue. Confirm the agent's `CERTCTL_SERVER_URL` env points at the in-cluster service name (`https://certctl-server.certctl.svc.cluster.local:8443`).
|
|
|
|
**Postgres won't start.** PVC permissions. Check `kubectl describe pvc -n certctl certctl-postgres` and confirm the storage class supports `fsGroup`.
