Migrate from Boot2Docker to Machine

Estimated reading time: 1 minute

If you were using Boot2Docker previously, you have a pre-existing Docker boot2docker-vm VM on your local system. To allow Docker Machine to manage this older VM, you must migrate it.

  1. Open a terminal or the Docker CLI on your system.

  2. Type the following command.

    $ docker-machine create -d virtualbox --virtualbox-import-boot2docker-vm boot2docker-vm docker-vm

  3. Use the docker-machine command to interact with the migrated VM.
