• Use of volumes: There are a number of ways of mounting or binding volumes into a container.
  • One strategy is to mount a Docker® volume which is managed by Docker®, typically in /var/lib/docker/volumes.
  • Another strategy is to map Docker® volumes to the local file system. This requires letting Docker® Compose know that the volume is locally managed and is in focus of the above example.
• Use of user accounts: see JS7 - Running Containers for User Accounts.
  • The RUN_JS_USER_ID setting holds the User ID and Group ID. Consider that the Group ID has to be 0  as directories and files in the image are owned by the root group.
