I have wrapped it into a Docker image which anyone can quickly use.

Docker Hub

Future

I think that it could be a nice store feature to Docker. So that instead of mounting configuration files as volumes (-v), we could use something like:

services:

  nginx:

    pubkv:

      nginx.conf: /etc/nginx/nginx.conf

  host: localhost

  port: 10080
