I mainly wanted to make sure and get this docker-compose.yml in here for future use.
Note the last couple of lines. You can set to the log file to digest all logs. However, GoAccess doesn't support any filtering per hostname, so if you want to see analytics for only a particular host name, you want would to just mount the proxy-host-1_access.log for example. npm creates one of these for each proxy host.
This is really just a helluva lot easier than what you need to do with Caddy.
Go to your DNS records in cloudflare and create an A record with a wild card to take care of all apps. Something like *.local. Determine the local IP address of your server. You can use ifconfig, or look at your router settings to find what the local IP is for that particular device. For Proxy status just do DNS only.
Install caddy from the docs: caddyserver.com/docs/install
I did this just using snaps
Install git as well
Install Caddy on your server.
