## Overview

Implement automated SSL/TLS certificate management across infrastructure, including provisioning, renewal, monitoring, and secure distribution to services.

## When to Use

- HTTPS/TLS enablement
- Certificate renewal automation
- Multi-domain certificate management
- Wildcard certificate handling
- Certificate monitoring and alerts
- Zero-downtime certificate rotation
- Internal PKI management

## Quick Start

Minimal working example:

```yaml
# cert-manager-setup.yaml
apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-prod
spec:
  acme:
    server: https://acme-v02.api.letsencrypt.org/directory
    email: admin@myapp.com
    privateKeySecretRef:
      name: letsencrypt-prod
    solvers:
      # HTTP-01 solver for standard domains
      - http01:
          ingress:
            class: nginx
        selector:
          dnsNames:
            - "myapp.com"
            - "www.myapp.com"

      # DNS-01 solver for wildcard domains
      - dns01:
          route53:
            region: us-east-1
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Automate certificate renewal
- Use Let's Encrypt for public certs
- Monitor certificate expiration
- Use wildcard certs strategically
- Implement certificate pinning
- Rotate certificates regularly
- Store keys securely
- Use strong key sizes (2048+ RSA, 256+ ECDSA)

### ❌ DON'T

- Manual certificate management
- Self-signed certs in production
- Share private keys
- Ignore expiration warnings
- Use weak key sizes
- Mix dev and prod certs
- Commit certs to git
- Disable certificate validation
