JupyterHub Disable Culling for a Specific User

MHamza-Y · January 1, 2023, 4:02pm

I am using my university server. The servers use JupyterHub for managing users etc. My workflow runs for about 10-12 hours. The idle culler shuts down my user notebook server after 2 hours. I contacted the admin of the server. But the admin have no idea how to disable the idle culler. He agreed to help me if I can tell him specifically what to do.

I found this article

But it applies the settings to all users (i think), which is not an option. Is there any way to to disable the idle culling for a specific user?

Thanks In advance. Also I am not familiar with jupyterhub so I apologize in advance if I missed something obvious.

The idle-culler uses the JupyterHub API

You could either modify the idle-culler:

github.com

jupyterhub/jupyterhub-idle-culler/blob/238f692584c99ec4ff5da11cbdca877ad977cc19/jupyterhub_idle_culler/init.py

#!/usr/bin/env python3
"""
Monitor & Cull idle single-user servers and users
"""

import asyncio
import ssl
import json
import os
from datetime import datetime
from datetime import timezone
from distutils.version import LooseVersion as V
from functools import partial
from textwrap import dedent

from urllib.parse import quote

import dateutil.parser

from tornado.log import app_log

or write your own script that culls idle servers, using some custom logic to exclude users.
