How to serve Jenkins?

Help
1

I want to serve Jenkins CI with Caddy.

Reading How to proxy from port to path I have this Caddyfile:

jenkins.example.com {
    proxy / http://localhost:8080
}

Now I access Jenkins on port 8080 and set the Jenkins URL in Jenkins settings. Then Jenkins complains that the reverse proxy setup is broken, see Reverse proxy configuration.

When I access it via https and port 80 some pages work but on lots of pages I get redirected to localhost:80.

Has someone successfully used Jenkins with Caddy?

It seems that using the transparent preset fixes this:

jenkins.example.com {
    proxy / http://localhost:8080 {
        transparent
        max_fails 0
    }
}

max_fails 0 for me was required because sometimes I got a 502 Bad Gateway response. See this caddy issue.
