New docker stack for a headless kernel #42
Conversation

@poplav Can you put a bit of text in the commit and/or on the PR so that folks know what this is and it can be discussed? Thanks! |
|
Thanks. I'd like to hold off for a little bit on merging this until the kernel_gateway matures a bit more. It might be good to point out in the README that it's a jupyter incubator project at the moment. @rgbkrk thoughts? |
|
Yeah I think putting this dockerfile on the incubator itself would be good. |
|
@rgbkrk Just to clarify, I do believe we should have a set of stacks here with kernels eventually (minimal-kernel, python-kernel, r-kernel, ...). I was only commenting on not wanting to send the wrong message that it's stable and ready to use by merging it today. Do you agree? |
|
Totally in sync there. Once we prove it out, we can put it here which tends to get interpreted as stable (or should be). |
|
So kernel_gateway 0.1.0 is now out on pypi and pip installable. It's already runnable with the jupyter/minimal-notebook image. @poplav it would be great if you could revisit this PR now and just |

Not sure we even need the jovyan user. Try using nobody which should exist in the container.

Don't want to run start-notebook.sh. Entrypoint should be something like the one over the kernel gateway demos like tini -- jupyter kernel_gateway and the CMD is --ip=0.0.0.0

nobody probably has no home dir. Maybe run in /tmp by default?

"that enables programmatic access to kernels" maybe?

The images size at commit b89f25d is 485.3 MB. |

Pretty slim, all things considered. |

I think this is good to go in. We can iterate over time. I'll merge this in later after setting up a second PR that updates the Makefile to make sure this new stack builds alongside the notebook based ones properly. |

New docker stack for a headless kernel. It uses the new kernel gateway from the Jupyter incubator project to provide websocket access without exposing the whole notebook UI.
I created the stack to be able to test the kernel gateway. Submitting it here for possible future inclusion into the official docker-stacks, and maybe to open up the discussion about kernel containers.
