Thanks for putting this together. I've given some initial comments. Lots of changes will be likely in the gateway-experiments repos.

@kevin-bates Thx a lot for your comments and the debugging session we have done yesterday.

I have invested more time today to debug the launch and the creation steps of the remote kernel. Something I have realized is that the python source changes are not picked up after the first invocation of those sources (even removing the pyc files). I have finally been able to have the pod remaining. Tried the grace-period... but finally simply remove the code responsible to remove the resource. The pod was working fine... so I have a second look at gateway-experiments/remote_kernel_provider@fc0fdea and it turns out that this was the cause.

Current Pr works fine

Let's further discuss the next steps at the weekly meeting.

I may add spark to this, but this is ready for review.
