Update: I found no valid mm container in the docker store.
You can build your own docker image locally with
docker build -t magic_mirror .
and run it with
docker run -d --publish 8080:8080 --restart always --volume ~/magic_mirror/config:/opt/magic_mirror/config --volume ~/magic_mirror/modules:/opt/magic_mirror/modules --name magic_mirror magic_mirror
and open it in your browser with
http://localhost:8080/
Be aware of this issue.
Karsten.
