        Recreate containers to add labels

        If you're coming from Compose 1.2 or earlier, you'll need to remove or
        migrate your existing containers after upgrading Compose. This is
        because, as of version 1.3, Compose uses Docker labels to keep track
        of containers, and so they need to be recreated with labels added.

        If Compose detects containers that were created without labels, it
        will refuse to run so that you don't end up with two sets of them. If
        you want to keep using your existing containers (for example, because
        they have data volumes you want to preserve) you can migrate them with
        the following command:

            docker-compose migrate-to-labels

        Alternatively, if you're not worried about keeping them, you can
        remove them - Compose will just create new ones.

        Recreate containers to add labels

        If you're coming from Compose 1.2 or earlier, you'll need to remove or
        migrate your existing containers after upgrading Compose. This is
        because, as of version 1.3, Compose uses Docker labels to keep track
        of containers, and so they need to be recreated with labels added.

        If Compose detects containers that were created without labels, it
        will refuse to run so that you don't end up with two sets of them. If
        you want to keep using your existing containers (for example, because
        they have data volumes you want to preserve) you can migrate them with
        the following command:

            docker-compose migrate-to-labels

        Alternatively, if you're not worried about keeping them, you can
        remove them - Compose will just create new ones.

            docker rm -f myapp_web_1 myapp_db_1 ...
