SSL HTTPS Configuration

Recommended: proxy_tls

PullPreview can automatically inject a Caddy service that obtains Let's Encrypt certificates and proxies HTTPS traffic to your app service.

Set:

with:
  proxy_tls: web:80

That means:

• incoming HTTPS traffic is terminated by Caddy
• requests are proxied to web service on port 80
• preview URL output/comment/status uses https://...:443

If your compose already publishes host port 443, PullPreview logs a warning and skips proxy injection.

Manual TLS compose setup

You can still manage TLS directly in your own compose files if preferred (custom Caddy/Nginx/Traefik config).

In that case, keep proxy_tls empty and configure service/ports yourself.
