Instructions for changing the default Docker folder.

The /var/lib/docker/ folder is the default Docker folder for Ubuntu, Fedora, and Deblan in a standard engine installation.

To change the Docker folder:

  1. Stop the Docker daemon.

    sudo service docker stop

  2. Create a file called daemon.json under the /etc/docker directory with the following content:

    {
            "data-root": "<path to your Docker folder>"
      }
  3. Copy the current data directory to the new one.

    sudo rsync -aP /var/lib/docker/ <path to your Docker folder>

  4. Rename the old docker directory.

    sudo mv /var/lib/docker /var/lib/docker.bkp

  5. After confirming that the change was successful, you can remove the backup file.

    sudo rm -rf /var/lib/docker.bkp

  6. Start the Docker daemon.

    sudo service docker start
