Here's a dockerfile setup I wrote for Postgres which uses a 'data container' for the entire Postgres database: https://github.com/codelittinc/dockerfiles/tree/master/postgres https://github.com/codelittinc/dockerfiles/tree/master/postg... The gist of it is that you explicitly tell your DB container that there will be a shared directory on the container at runtime. This allows you to chown the directory before the data container is added. Then, when you're running, use --volumes-from `$data-container-name` and it'll work. Want an article on it?
