# cert-manager Automated Let's Encrypt TLS Provisioning

Deploys cert-manager: configuring ClusterIssuer for ACME HTTP-01 and DNS-01 challenges (Route53, Cloudflare), automatic Ingress TLS certificate injection, certificate renewal metrics, and wildcard domain certs.

## When to Invoke
Invoke this skill whenever you need to:
- setup cert-manager clusterissuer
- dns-01 challenge cert-manager cloudflare
- auto tls ingress cert-manager

## Execution SOP & Rules
1. Install cert-manager with CRDs enabled: helm install cert-manager jetstack/cert-manager --set crds.enabled=true.
2. Create ClusterIssuer with acme.server: https://acme-v02.api.letsencrypt.org/directory.
3. Configure solvertype http01 or dns01 with secretRef credentials.
4. Check certificate lifecycle status: kubectl get certificate,certificaterequest,order,challenge.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
