Enter a repository name:
Repository names must match [a-z0-9_-]+

Once a container has terminated in Docker, the next step is to commit the container to an image, and then tag that image with a relevant name so it can be saved to a repository.

Docker lets us do this in one step with the commit command. To do so, we run the `docker commit` with the container ID from the previous step and tag it to be a repository under `{{ tour.tourScope.domainName }}`.

    sudo docker commit {{ tour.tourScope.containerId || 'containerId' }} {{ tour.tourScope.domainName }}/{{ tour.tourScope.username }}/{{ tour.tourScope.repoName || 'myfirstrepo' }}
