Automatically publish .local addresses from Docker Compose labels (github.com)

Inspired by everyone here, I've spent the past few months playing with hosting my own instances of various open source projects. I just use them on my local network, and love the automatic mDNS my_machine_name.local addresses.

I also love Traefik's use of Docker Compose labels as a source of hostname configuration (docs), so I thought it would be nice to automatically publish these too!

If this sounds interesting, you can find usage instructions and technical details on GitHub. This is my first published project, so I apologize for any rough edges, but I'll try my best to accommodate feedback :)

I've switched over to using a publicly resolvable domain name, but with a lan prefix (e.g. lan.mystuff.dev) so that I can do DNS challenge let's encrypt certs.

Paired with PowerDNS that acts as an authority for the lan.mystuff.dev domain, I can go to a legit certificate/SSL protected https://sonarr.lan.mystuff.dev url. If I wanted to, I could add cloudflare records for the same services exposed through my router (Like for vpn.lan.mystuff.dev) so that both internal and external resolution is possible.
