Automated Caddy Reverse Proxy for Docker - based on jwilder/nginx-proxy and BlackGlory/caddy-proxy
docker-caddy-proxy sets up a container running caddy and [docker-gen][1]. docker-gen generates reverse proxy configs for caddy and reloads caddy when containers are started and stopped.
To run it:
$ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro banovo/docker-caddy-proxy
Then start any containers you want proxied with an env var VIRTUAL_HOST=subdomain.youdomain.com
$ docker run -e VIRTUAL_HOST=foo.bar.com ...
The containers being proxied must expose the port to be proxied, either by using the EXPOSE directive in their Dockerfile or by using the --expose flag to docker run or docker create.
Provided your DNS is setup to forward foo.bar.com to the a host running caddy-proxy, the request will be routed to a container with the VIRTUAL_HOST env var set.
