For those who remember my "docker-auto-dns" project, I recreated a better one in #Go here:
https://github.com/metal3d/docker-domains
It provides a full domain resolution to your #Docker #containers!
If you want to know what's behind the scene: it starts a #dnsmasq server on "docker0" interface and automatically add domains entries (support wildcard) - and it temporary setup "resolved". That's all!
I precise: this allows you to start a container, and to connect to it with its name.local, or whatever the "hostname" you set. That's not a HTTP router like Traefik, it's a name resolution.
