Often, I would like to play with what volumes are mounted, or what command is executed, without having to rebuild the docker image.
This takes a long time when working on a JupyterLab extension that depends on JupyterLab master and so has to rebuild all of JupyterLab every image build.
Currently, I am looking for the image name manually with docker image ls and running it manually. This isn't ideal, because then it isn't run in the same way as repo2docker is running it. You pass some extra options on start, like a port and the custom display URL. I would like to keep all these nicetities and not have to hunt in the image list for the most recent one.
I thought this is what the --no-build argument would do, but I guess it not only doesn't build but doesn't start. For example, docker-compose up has a --no-build argument that won't build the images, but will start up the services.
