Docker image

Hey jupyter retrolab is amazing

I was trying to setup retrolab inside docker
Everything works fine ,
But jupyter lab is not working,
Like it returns 502 error (internal server error)

Thx in advance 😊

Thanks @nv2k3.

Are you able to use jupyterlab in a Docker image? If so retrolab should also work.

Would you be able to share the Dockerfile you are trying to use?
