A note on static IPs

[tonymcneil]

Nice write up!

Just an FYI as I've been looking into routing too.

Your README states:

A drawback is we need to give a static IP which points to traefik, which is not very handy.

(under the Add host entry to container heading).

I've recently noted that you can do this in a docker compose file:

extra_hosts:
      - "keycloak.my.domain:host-gateway"

Where host-gateway is the important part that avoids IP references. So far I've just tested this on linux running Docker Engine, so I'm hoping it'll work on all platforms / install mechanisms.

Thank you very much @tonymcneil ! I think this is the best solution. The service in docker-compose can choose which services to resolve via host system.

No need to specify the traefik network and the connection just works. Well done!

Cheers
