Automatic Nginx proxy config generator

This uses my docker-service-reporter container to generate an nginx config file defining virtual hosts that proxy to docker containers with appropriate labels.

How?

The service-reporter container populates etcd with details about known containers.

This container monitors etcd for a label specifying vhosts and proxy ports, and puts them into a template file for nginx to use.

Labels

You must label any container that you wish to proxy. The following labels are understood:

• com.chameth.proxy=<port> -- specifies the port on the container that the proxy should connect to
• com.chameth.proxy.protocol=<protocol> -- the protocol to use when connecting to the container. Optional, defaults to HTTP.
• com.chameth.vhost=<host> -- the virtual host that the proxy will accept connections on. You can specify alternate hosts/aliases by separating them with commas.

Usage

TODO: Finish this!

Then run this container. It takes the same arguments as service-reporter:

  --etcd-host (default: etcd) hostname where ectd is running
  --etcd-port (default: 2379) port to connect to ectd on
  --etcd-prefix (default: /docker) prefix to read keys from
  --name (default: unknown) name of the host running docker
