Hello, @edp

Have you ever tried set cmd part?

singleuser:
  cmd: #emtpy

if i setup
singleuser:
cmd: jupyterhub-singleuser # this is values.yaml’s default value
the notebook default user is jovyan and uid:1000

if i setup:
singleuser:
cmd: # ← here i leave it blank
the notebook default user is jovyan and uid:1000

also i can’t use kubectl logs or kubectl logs <user’s-jupyter-pod-name> find self.log.debug information. is this right configuration?

Thank you again @manics @hiroyuki-sato
