How to pass options to JupyterLab from JupyterHub

[edbennett]

I’m trying to disable the default “Python (ipykernel)” kernel in my JupyterHub deployment; per this discussion on StackOverflow this can be done by setting c.KernelSpecManager.ensure_native_kernel = False or launching the Lab with jupyter lab --KernelSpecManager.ensure_native_kernel=False. How is this done when JupyterLab is being launched via JupyterHub, please?

There are two options:

• Create a jupyter server configuration file in a location that will be picked up by JupyterLab: Configuring a Jupyter Server — Jupyter Server documentation .
• Pass additional arguements in the spawner configuration: Spawners — JupyterHub documentation

–KernelSpecManager.ensure_native_kernel=False

Ah, I see—I’d seen the former link but hadn’t realised that command-line flags to jupyterhub-singleuser would be passed through to jupyter lab. Thanks!
