How to change the default location for “docker create volume” command?

by

You can change where Docker stores its files including volumes by changing one of its startup parameters called --data-root.

If you’re using systemd for service management, the file is usually located at /lib/systemd/system/docker.service. Edit the file as such:

# Old - taken from the generated docker.service file in Ubuntu 16.04's docker.io package
ExecStart=/usr/bin/dockerd -H fd:// $DOCKER_OPTS

# New
ExecStart=/usr/bin/dockerd --data-root /new_location/ -H fd:// $DOCKER_OPTS

Alternatively, you can edit the Docker daemon configuration file which defaults to /etc/docker/daemon.json.

Restart the Docker daemon and your volumes will be under /new_location/volumes/{volume_name}/_data

Note: be careful in production and also locally! You also have to move the existing data from /var/lib/docker/ to the new location for your docker install to work as expected.

You can use symlinks from the new location if you want specific folders to be in specific place.
