Button to UI for managing named servers

[jhgoebbert]

Hello jtpio,

another real helpful button could be one in JupyterHub scenario, which sends the user back to the control panel, which lists all running jupyter notebook servers in jupyterhub 1.x:

I tried to use jupyterlab-logout for that and make it point to
https:///integration/hub/start
with
function () { router.navigate('/hub/start', { hard: true })
which is obviously wrong as it points to
https:///integration/user/<user_name>/<server_name>/hub/start

Do you have any idea how that could be possible?
Perhaps that could be another button for jupyterlab-topbar.

Best regards,
Jens Henrik

@jhgoebbert if by pointing it to /hub/home?

[jtpio]

Or rather: router.navigate('/home')

[jhgoebbert]

If that leads to the page for named server, which was introduced with JupyterHub 1.0 ( https://blog.jupyter.org/announcing-jupyterhub-1-0-8fff78acad7f ), it would be perfekt. I will test it.

[jtpio]

They should indeed show up on the home page.

If that works maybe it's worth making a new jupyterlab-hub extension, that could expose some of these shortcuts to the user when used in a JupyterHub environment.

The existing hub-extension in JupyterLab core already has some integration with JupyterHub, limited to Control Panel and Log Out for now:

[jhgoebbert]

Great.
The hub-integration extension is hiding the "Log Out" and "Hub Control Panel" in the File menu. Users often do not find it there and are not aware of this functionality. Having a button would fix that.

Hey jtpio,
I hope you don't mind that I created a package for this ( https://www.npmjs.com/package/jupyterlab-control ) and linked you there. The only problem right now is that JupyterLab has no /home path. One has to add a redirect rule to the proxy, to catch the /home path of the JupyterLab.

An example for our nginx (where users name are emails, and JupyterLab Names are restricted to [a-z0-9_]):
location ~ "/user/([a-z0-9_.-]+)@([\da-z.-]+).([a-z.]{2,6})/[a-z0-9_]+/home" {
return 301 /hub/home;
}

If you want to add such a package by yourself I can remove my package.

That's great, thanks @kreuzert for sharing!

No problem at all! Credit is not required but thanks for the shout-out :)

Maybe there could be some logic that checks whether JupyterLab is running in a hub environment, like this: https://github.com/jupyterlab/jupyterlab/blob/master/packages/hub-extension/src/index.ts#L49-L52

I had no plans to create such package. If you want we can add a link to it in the list of topbar extensions: https://github.com/jtpio/jupyterlab-topbar#extensions
