In Dockerfile we can use VOLUME /some/folder to let docker always create a volume for the specified folder when calling docker run, without having to explicitly use the -v parameter. The volume created will have a random (unreadable) alphanumerical name.

Question: is it possible to specify a readable name for the volume on container creation?


You do not specify a volume source when you define a volume in an image. Doing so would be a potential security exploit where an image could mount a private volume with a common name and send the contents of that volume over the network. To create your volumes with known names, and have that defined in a file, you would do that at runtime with a docker-compose.yml file when the container is created. E.g.

version: '3'
  - app_data
    image: your_image:1.0
      - app_data:/data
