Custom Domains

Use custom domains to expose services on your own hostnames.

Setup flow

1. Create HTTPRoute with your hostname.
2. Ensure DNS points to your platform ingress endpoint.
3. Issue TLS certificate for that hostname.
4. Verify endpoint and certificate chain.

Cutover strategy

• Lower DNS TTL before migration.
• Deploy route and certificate before changing public DNS.
• Validate with curl -I https://<hostname> and synthetic checks.

Common pitfalls

• Route hostnames and DNS records do not match exactly.
• Certificate not issued for all required SANs.
• Old DNS records still cached by resolvers.
