⁠docker-caddy-proxy

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.

⁠Usage

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.
