Hi!

Thanks for making this build (has saved me some time).

I noticed that it seemed like the container wasn't monitoring the docker socket, and wasn't picking up any changes from caddy labels on other containers. Looking at the instructions on the caddy-docker-proxy project (here), it looks like the dockerfile is missing the following at the end:

CMD ["caddy", "docker-proxy"]

I've worked around it by adding command: caddy docker-proxy to my docker-compose file but I'm guessing you might want to update your dockerfile.
