Montera en fysisk disk i en container

Källa: https://serverfault.com/questions/1053820/can-docker-volumes-be-mounted-from-a-device-instead-of-bind-mounting-a-directory

On a linux docker host this is possible by first creating named volume with a local driver.

The named volume is just a specification for what to mount when the container starts so the device does not need to be plugged in when the volume is created.

From docker you first create a named volume. Let's say the device I want to mount is an ext4 drive and will always appear as /dev/disk/by-uuid/d28c6d3a-461e-4d7d-8737-40e56e8f384a:

# Create "my-volume"
docker volume create --driver=local --opt type=ext4 --opt device=/dev/disk/by-uuid/d28c6d3a-461e-4d7d-8737-40e56e8f384a my-volume
# Run a container with it mounted to a path.
docker run -v my-volume:/my-volume --rm -it alpine sh
