Missing documented feature for "docker run -v /app/node_modules" which does not specify source dir?

  • In the case of named volumes, the first field is the name of the volume, and is unique on a given host machine. For anonymous volumes, the first field is omitted.

But I never use anonymous volumes. Those can fill up your disk and you will not even know what that volume was for unless it is mounted to a container at the moment.
