make jupyterhub idle server more easily configurable #390

fmigneault · 2023-10-12T21:54:30Z

Overview

Add new variables to easily configure idle jupyter user instances.

Changes

Non-breaking changes

Jupyterhub configurable idle server culling.
- Add optional variables JUPYTER_IDLE_SERVER_CULL_TIMEOUT, JUPYTER_IDLE_KERNEL_CULL_TIMEOUT and
  JUPYTER_IDLE_KERNEL_CULL_INTERVAL that allows fined-grained configuration of user-kernel and server-wide
  docker image culling when their activity status reached a certain idle timeout threshold.
- Enable idle kernel culling by default with a timeout of 1 day, and user server culling with timeout of 3 days.
- Avoids the need for custom JUPYTERHUB_CONFIG_OVERRIDE specifically for idle server culling.
  If similar argument parameters should be defined using an older JUPYTERHUB_CONFIG_OVERRIDE definition,
  the new configuration strategy can be skipped by setting JUPYTER_IDLE_KERNEL_CULL_TIMEOUT=0.

@tlvu @mishaschwartz

I've tested it using some low values (eg: JUPYTER_IDLE_KERNEL_CULL_TIMEOUT=10).
At some point, my jupyter-<user> image got shut down, though it took longer than anticipated.
Some jupyter-server docs indicate that shutdown could take longer, considering the timeout only triggers the request to shutdown, but does not monitor/consider the shutdown duration itself.
Either way, at least, it shut down at some point, without the need of the other strategy.

I've opted for a default 1day timeout to promote servers using defaults/minimally-overridden configs to have cleanup enabled with some reasonable time, so user can experiment for some time without being impacted by shutdown, while stopping automatiically when they are clearly not using it anymore.

LGTM. Please update env.local.example with the 3 new vars and their documentations and delete the corresponding sample for JUPYTERHUB_CONFIG_OVERRIDE.

birdhouse/config/jupyterhub/jupyterhub_config.py.template

+        jupyter_idle_kernel_cull_interval = jupyter_idle_kernel_cull_timeout / 2
+    c.Spawner.args.extend([
+        '--MappingKernelManager.cull_idle_timeout={}'.format(jupyter_idle_kernel_cull_timeout),
+        '--MappingKernelManager.cull_interval={}'.format(jupyter_idle_kernel_cull_interval),


Funny I didn't have to manually set the cull_interval to haft of the cull_idle_timeout and it was working fine. What is the default value of the 2 cull_interval if not set?

300 seconds I believe

Indeed, there is the default of 300 from jupyter-server, but with my proposed changes at L205, the value is automatically halved from the timeout if not specified. I had to do this, otherwise the interval between updates took at least 300s regardless of my timeout=10 test.

tlvu · 2023-10-13T00:45:26Z

I've tested it using some low values (eg: JUPYTER_IDLE_KERNEL_CULL_TIMEOUT=10).
At some point, my jupyter-<user> image got shut down, though it took longer than anticipated.

I assume you also set JUPYTER_IDLE_SERVER_CULL_TIMEOUT=10? So with those 2 configs, after 10 sec, the notebook kernel got killed, then 10 sec later the server is killed.

The server cull timeout starts only when all kernels are down.

For us at Ouranos, we set the server timeout to 4 days and the kernel timeout to 1 day. Together, they account for 5 days of complete inactivity before the server is actually gone, so any 4 days long weekend is taken care of.

Given this new config, if JUPYTER_IDLE_SERVER_CULL_TIMEOUT is not set or is zero (the default), the server would not be killed at all.

I think we should put some value to avoid the server running forever. Maybe a bigger value like a week would be reasonable?

mishaschwartz

Looks good to me.

I agree with this though:

So I'd also like to see that default changed before we merge this

Indeed. Sorry for the confusion. Both variables were set at 10s.

LGTM. Maybe set the server timeout to 4 days instead of 3 days so the guy coming back from a 4 days long weekend have a chance resume his work?

I'd consider that an edge case. Also, they should be able to resume work from a notebook saved in the user-workspace that would be re-mounted on server restart.

Yes it's an edge case.

It's not about preserving the notebooks, it's about preserving any custom installs the user had made without properly recording them in a requirements.txt or environment.yml.

It's fine, 3 or 4, the node admin with adjust if they receive complains over long weekend.
