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:

# cert-manager-setup.yamlapiVersion: cert-manager.io/v1kind: ClusterIssuermetadata:  name: letsencrypt-prodspec:  acme:    server: https://acme-v02.api.letsencrypt.org/directory    email: [email protected]    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
