Yannick Lyn Fatt writes that new updates to the `serversideup/php` Docker images allow FrankenPHP containers to serve real HTTPS via Let's Encrypt using only an IP address. By utilizing the `shortlived` ACME profile, users can obtain valid certificates without requiring a DNS entry, which is particularly beneficial for self-hosting, staging environments, or internal APIs reachable by IP.
- Requires pinning the Docker image to v4.6.0-beta1 or later.
- The short-lived certificate profile issues credentials valid for 160 hours.
- Configuration requires setting a `default_sni` via `CADDY_GLOBAL_OPTIONS` because IP connections lack SNI metadata.
- Certificates and ACME state must be persisted in `/config` and `/data` volumes to avoid Let's Encrypt rate limits during redeploys.
