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 know some are vehemently against the use of .local for a home network. It would be nice to be able to set a custom TLD like .home or .lan (these don't have any special meaning or usage as of now).

If you prefer, I think Avahi is able to publish other TLDs, but I played around with it just now and couldn't get it to work. If you have any luck, let me know what worked for you and I'll try to add support :)

This is what I tried, but it fails with Failed to add address: Not supported:

# Set domain-name=lan and enable-wide-area=no
nano /etc/avahi/avahi-daemon.conf
sudo avahi-daemon --reload
sudo avahi-publish-address -R example.lan 192.168.1.123
