When using binderhub with auth (as for instance described here https://binderhub.readthedocs.io/en/latest/authentication.html) the suggestion is to set jupyterhub.singleuser.cmd to jupyterhub-singleuser. Doing so overrides the magic that has been added to default to lab if it's installed. I can handle this by taking said magic out of the values.yaml file and adding it to my config.yaml file, as shown below, but it would be nice if there were a different variable to put things like "jupyter-notebook" or "jupyethub-singleuser" in that then got substituted into the os.execvp bit. I have no idea what the architecture of this bit of code is, so I wouldn't know how to do what I want, but something like inner_cmd: jupyterhub-singleuser would seem nice.
cmd:
- python3
- "-c"
- |
import os
import sys
try:
import jupyterlab
major = int(jupyterlab.__version__.split(".", 1)[0])
except Exception:
have_lab = False
else:
have_lab = major >= 3
if have_lab and "NotebookApp.default_url" not in " ".join(sys.argv):
# if recent-enough lab is available, make it the default UI
sys.argv.insert(1, "--NotebookApp.default_url=/lab/")
# launch the notebook server
os.execvp("jupyterhub-singleuser", sys.argv)
