Server options not showing environments

Server options not showing environments

lachlancampbell opened this issue 3 years ago · comments

Hi, I've had a working Plasma instance running on an Openstack cloud for several months with no problems. Yesterday I created a new instance and successfully ran the playbooks to create a new hub. The new hub will not allow a user server to be started - Error: DockerError(400, 'no such image: None: invalid reference format: repository name must be lowercase'). I'm assuming this is because the Server Options page (/hub/spawn) is not showing any of my environments, so I can't select them. I also did a quick check of the logs and it showed a PAM login error (similar to jupyterhub/jupyterhub#2754). I'm also assuming this behaviour is due to an update to TLJH or jupyterhub itself, as my old Plasma hub is still working fine.

Thanks @lachlancampbell for reporting.

Out of curiosity, what does the name of the environment look like? It could be that tljh-repo2docker didn't sanitize it correctly.

I think it was "plain-python". I don't think it was the name though, as I used an image of my working VM to create a new one, and tried importing and it showed up fine in the environments. I've since deleted it, but I could try and replicate it. I did confirm that the PAM error occurs on my working hub, so not related.

@jtpio -- I'm seeing similar symptoms, not sure whether it is a related problem or not. I'm happy to open up my digital ocean droplet where this is currently running.

I've succeeded in creating 3 environments using the templates which all work with binder:

But users don't see the environments when they log in:

And instead the plugin gives them the non-existent jupyterhub/singleuser:1.1 environment

Plasma is exactly what we're looking for at UBC for pangeo-ready jupyterhubs -- happy to do whatever it takes to get this working.

👋 @phaustin sorry for the delay.
Did you go into the Permissions tab to set the visibility of your environments to the group your user belongs to?
