Live reload of gateway on file change

[itproto]

Is it some way to update kernel gateway REST service after updating target .ipynb

I am running docker container with the following entrypoint ENTRYPOINT ["tini", "--", "/docker-entrypoint.sh"]

start-notebook.sh --NotebookApp.port=9999 --NotebookApp.notebook_dir=/srv/notebooks/ &
jupyter kernelgateway --KernelGatewayApp.port=7777 --KernelGatewayApp.api=notebook-http --KernelGatewayApp.ip=0.0.0.0 --KernelGatewayApp.seed_uri=/srv/notebooks/hello.ipynb
e

I want to run both processes at the same time. I can access and edit the target hello.ipynb , but rest API never reflects changes (until container restart).

Is it possible to "live-reload" gateway on file change?

This capability doesn't exist today. I added dynamic configuration support to Enterprise Gateway at an experimental level that could probably be leveraged here. It would require that seed_uri be configured via a configuration file (which would need to be mounted into the container) and you'd probably need to add an observe trait to force JKG to re-populate its use of the notebook.

I'm not very familiar with the http-personality and don't know if this kind of "reset" is possible w/o restarting the server though - so you'd need to experiment with it.

Just some thoughts.

Kevin, thank you for your thoughts. That is very insightful. I was just playing around with idea of live preview of notebook as rest/web-socket API. I am going to experiment with a best restart technique.
