User/Group override

You can easily override the user/group used by the image using environment variables. Like in the following compose example:

# https://docs.docker.com/compose/yml/

node:
  container_name: node
  hostname: node
  image: mgcrea/node:6
  environment:
    - NODE_USER=www-data
    - NODE_GROUP=www-data
    - UID=33
    - GID=33
  ports:
    - "3000:3000"
  volumes:
    - ./www:/srv/www
  restart: always

NOTE: for security reasons, starting this docker container will change the permissions of all files in your www directory to a new, docker-only user. This ensures that the docker container can access the files.
