説明
I was expecting repo2docker https://github.com/binder-examples/conda-freeze /bin/bash to give me a shell inside the container. Instead it builds the image and then exits straight away.
I think this is because we would have to do the equivalent of docker run -it <image> /bin/bash but don't. Should we add a --interactive CLI flag that turns on this behaviour?
Note: a solution to this is outlined in https://github.com/jupyter/repo2docker/issues/599#issuecomment-483402517. This would be a good way to get involved with contributing to repo2docker and something to help out with in general.
