I'm working on a project, and one of the steps is to allow contributors to be able to use Jupyter Lab on the Gitpod. Also in our project, we assume that users can use Jupyter Lab on a compute cluster and connect to it from home. So basically our problem is related to accessing a remote Jupyter Lab server.
When I started testing this functionality, I noticed that we had a kernel connection problem (none of the used kernels can connect properly).
I started looking for information and found here and here that we need to change config options in jupyter_notebook_config.py. So I changed default option which is
c.ServerApp.allow_origin = ' '
to
c.ServerApp.allow_origin = '*'
After that change all kernels are connected properly. But I started to wonder about security.
Is it safe to do it this way? I know that Jupyter Lab requires a token to be able to connect to the server and maybe that's enough, but I'm not sure.
