nginx-proxy sets up a container running nginx and docker-gen. docker-gen generate reverse proxy configs for nginx and reloads nginx when containers they are started and stopped.

See Automated Nginx Reverse Proxy for Docker for why you might want to use this.

Usage

To build it:

$ docker build -t camomile/nginx-proxy .

To run it:

$ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock camomile/nginx-proxy

Then start any container you want proxied with env vars VIRTUAL_HOST=subdomain.youdomain.com and VIRTUAL_PATH=location

$ docker run -e VIRTUAL_HOST=foo.bar.com -e VIRTUAL_PATH=baz ...

Provided your DNS is setup to forward foo.bar.com to the a host running nginx-proxy, a request to foo.bar.com/baz will be routed to the container with the matching VIRTUAL_HOST and VIRTUAL_PATH env vars set.

Multiple Ports

If your container exposes multiple ports, nginx-proxy will default to the service running on port 80. If you need to specify a different port, you can set a VIRTUAL_PORT env var to select a different one. If your container only exposes one port and it has a VIRTUAL_HOST env var set, that port will be selected.

Multiple Hosts

If you need to support multipe virtual hosts for a container, you can separate each entry with commas. For example, foo.bar.com,baz.bar.com,bar.com and each host will be setup the same.
