So visiting https://must.af.catalystproject.2i2c.cloud is returning a 404 for me 😕

Okay, so it will be available when it's merged? I edited the PR comment.

Also, do I need to change any other configurations in the load balancer? 🤔

No, if you've run deployer deploy $CLUSTER_NAME $HUB_NAME locally it should be available immediately. We tend to deploy new hubs manually first and check they work, ask for feedback from the hub champion, before merging, as we can sometimes make tweaks as part of the setup.

If you have deployed locally, then we need to do more investigation as to why this is not working, but I cannot see any obvious issues from the files changed (though I am on my phone).

Fantastic! No, I didn't deploy it locally. Now it's running!

Edit: I just noticed that the logo has white letters, which are not visible with the white background.

Nice! Before sharing this with the Community Champion, we need to provide a jupyter/scipy image instead of a rocker based image.

Something like

jupyterhub:
  singleuser:
    image:
      # This image specification is likely overridden via the configurator.
      #
      # jupyter/scipy-notebook is maintained at: https://github.com/jupyter/docker-stacks
      # tags can be viewed at: https://hub.docker.com/r/jupyter/scipy-notebook/tags
      name: jupyter/scipy-notebook
      tag: "2023-07-06"

should do it.

[AIDEA775]

Aah! I didn't see that. Done!

After logging in, I get bounced to https://must.af.catalystproject.2i2c.cloud/user/[email protected]/rstudio? (which gives a 404)

I think I should be redirect to https://must.af.catalystproject.2i2c.cloud/user/[email protected]/lab (which does work).

I haven't yet looked at why this occurring.

[sgibson91]

I think now we have a hub on this cluster using a different image, it makes sense to move the R/RStudio image definition from common.values.yaml file and into the relevant hub-specific values files. I was going to do this after this PR was merged, but we may have to do it beforehand if there's a problem with this hub.

Probably what is happening is that not everything related to the image and setting up R envs is being fully overwritten by the Python image spec.

@jmunroe We are picking up rstudio as the default URL from these lines in common.values.yaml

infrastructure/config/clusters/catalystproject-africa/common.values.yaml

Lines 81 to 82 in 31d7b50

	working_dir: /home/rstudio
	default_url: /rstudio

@AIDEA775 I opened AIDEA775#1 which you should be able to merge into this PR. Then if you redeploy, I think the problem James reported will be fixed.

[AIDEA775]

Okay, redeployed, and now it's working properly.

Note: The default url is https://must.af.catalystproject.2i2c.cloud/user/[email protected]/tree no /lab.

[AIDEA775]

@jmunroe @sgibson91 Any update on this? Can we proceed?

[sgibson91]

@AIDEA775 Have you commented on the related issue and invited the community champion to try it and provide feedback?

[AIDEA775]

The community champion gave the okay. I rebased the branch to maintain a clean history :D

[sgibson91]

LGTM, merge when you like :)
