  • Use of volumes: There are a number of ways how to mount or bind volumes into a container.
    • One strategy is to mount a Docker® volume that is managed by Docker® typically in /var/lib/docker/volumes.
    • Another strategy is to map Docker® volumes to the local file system. This requires to let Docker® Compose know that the volume is locally managed. This is what the above example is focused on.
  • 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.
