Access your Jellyfin anywhere with Caddy

[pxr5]

I hope the OP, Matt, will see this post as I think he's the creator/maintainer of caddy-dynamicdns.

I've been using Caddy v2 for quite a while now, but was using a little Windows app to automatically update my IP when needed. Until I read this post properly and discovered Caddy itself can be used for Dynamic DNS. I've managed to install both plugins successfully (caddy-dynamicdns and the dynu plugin), though I did have to register dynu on the Caddy Downloads. Anyway this is where I'm getting a bit stuck with Caddyfile entries. 

caddy-dynamicdns gives Minimal Example Config for the Caddyfile as:

Code:

{
        dynamic_dns {
                provider cloudflare {env.CLOUDFLARE_API_TOKEN}
                domains {
                        example.com
                }
        }
}

The Dynu example config for the Caddyfile is like this:

Code:

tls {
        dns dynu {env.DYNU_API_TOKEN} {
        own_domain {env.OWN_DYNU_DOMAIN}
        }
}

So which do I use? I've knocked up my own Caddyfile and it looks like this, using both examples above:

Code:

{
        dynamic_dns {
                provider dynu apiapiapiapi
                domains {
                        mydomain.exmaple.com
                }
        }
}

mydomain.exmaple.com {
        reverse_proxy 192.168.x.xx:8080
}

tls {
        dns dynu apiapiapiapi {
        own_domain mydomain.exmaple.com
        }
}

I just need some clarity about what exactly goes in the Caddyfile. Thanks.
