My first thing! I’ve been playing with random things in Docker containers on random local devices recently, but I didn’t like using IPs, or ports, or managing DNS servers, or adding DNS entries to all my clients. I love how Traefik configures itself based on Docker compose labels, so I made a tool that does the same thing, but for using mDNS to publish .local addresses:

github.com/ducklol2/quack_domains

I swear that I looked around for something like this prior to building it myself, and somehow I didn’t find anything - but turns out many others have built something similar. Check them out too, see what makes sense to you!
