Code Server doesn't work on jupyterhub/kubernetes

[sa-]

• VSCode Version: latest
• Local OS Version: macOS
• Remote OS Version: ubuntu
• Remote Extension/Connection Type: Server
• Logs:

Steps to Reproduce:

1. Deploy jupyterhub to kubernetes
2. Add some sort of SSO (Single Sign-On) authentication to jupyterhub
3. Create a jupyter server
4. Open a terminal
5. Run wget -O- https://aka.ms/install-vscode-server/setup.sh | sh
6. Run sudo chmod +x /usr/local/bin/code-server
7. Run code-server serve-local --without-connection-token --accept-server-license-terms
8. Try to access VS Code and find only a blank page. There are some errors in the console

Does this issue occur when you try this locally?: n/a Does this issue occur when you try this locally and all extensions are disabled?: n/a

^The label should be for server rather than ssh

Do you have a screen recording of what you see in vscode.dev when you try to connect? Or logs from the code-server?

Hey thanks for having a look at this.

I'm running this with the command serve-local so vscode.dev is not involved in this process. The only logs are in the screenshot that I provided, the code-server logs seem to be blank.

@DonJayamanne any thoughts

[jiyuanq]

I'm encountering the same issue. Wondering if there's any update? Judging from the errors it looks like it's trying to load js from /hub, where the jupyterhub login service is, but the right path should be something like /user/<username>/code-server/...

[sa-]

Yeah - not sure what https://github.com/coder/code-server does differently, but that works just fine

[jiyuanq]

I guess it’s about absolute path vs relative path. VS code is using absolute paths which points to /hub as root path

[sa-]

@microsoft if I were you I would hire @jiyuanq

[jabbera]

You need to use the jupyter server proxy to rewrite the url:
