Goal
Run a small HTML app that starts a container within the Jupyter instance.
The nested container is started via Dockerode from a Node.js app - just like the o2r reference implementation.
The realisation is modelled after nbstencilaproxy.
The first step is to only use start and postBuild scripts, leaving many bits hard-coded.
Try it
You need a repo2docker fork that allows execution as root user, see https://github.com/o2r-project/repo2docker/tree/allow_root
repo2docker --debug --volume=/var/run/docker.sock:/var/run/docker.sock --env ERC_PATH=$(pwd)/erc --user-id=0 --user-name=root .
Then open the UI at /o2r-ui or via the "New > ERC" menu, or inspect the API at /o2r-api/v1/status.
You can query the API directly if you provide the token and adjust the port:
curl http://127.0.0.1:53889/o2r-api/v1/status/?token=2d77384eb9cbb8190b06709cc790b0bf441de3b25ec6ffee
Open questions
- How can the volume mount of the ERC be automated?
- Is this really feasible, given that I trust the users who are allowed to open a repository on Binder (i.e. I know who they are, and normally I control the repository content, too)?
- What changes need to be made to this kind of repository and image to work on JupyterHub?
