Try out jupyter-fs extension file-browser alternative

[rtapella]

Would like to install this in my jupyter workspace: https://github.com/jpmorganchase/jupyter-fs

Need to pip install && add to jupyter_server_config.json

I am able to successfully install jupyter-fs, but I cannot find a current jupyter_server_config.json and am having trouble creating a persistent one myself. The paths from jupyter --paths that exist are in in opt/conda (which doesn't persistent on restarts) and .projects/jupyter which I thought should persist on restart, but I am unable to create a file with touch in the dockerfile and creating a file manually in the ade in this folder is not persisting on restart. RUN jupyter server --generate-config also isn't working. Any suggestions?

There are some bugs in previous versions of jupyter-fs (0.3.1 and lower), and I was only able to reliably get jupyter-fs v0.4.1 to work locally with jupyterlab4, so I recommend we hold off on this until we upgrade to jupyterlab4 This does seem like a handy package though

Okay thanks for trying it out. I was not able to successfully install it. I wanted to just try it out to see if it's worth adopting

I have been unable to get jupyter-fs successfully working in the ADE. I have tried the following:

• locally replicated a conda environment the same as the ADE and jupyter-fs worked locally after generating the jupyter_server_config.py with jupyter server --generate-config in the jupyter --config-dir folder. Adding

  c.ServerApp.contents_manager_class = "jupyterfs.metamanager.MetaManager"
  c.ServerApp.jpserver_extensions = {"jupyterfs.extension": True}

  worked or also

  c.NotebookApp.contents_manager_class = "jupyterfs.metamanager.MetaManager"
  c.NotebookApp.nbserver_extensions = {"jupyterfs.extension": True}

  Or, adding a jupyter_server_config.json in the jupyter --config-dir folder with

  {
  "ServerApp": {
  "contents_manager_class": "jupyterfs.metamanager.MetaManager",
  "jpserver_extensions": {
    "jupyterfs.extension": true
  }
  }
  }

  worked too

All these different variations of jupyter_server_config.json and jupyter_server_config.py do not work in the ADE. I was using the url osfs:///projects. We don't have s3 access without credentials so can't be doing s3:// links, need to be doing osfs://

• I tried installing jupyter-fs with conda, pip, and npm and none work

Other notes:

• error messages in the console in the ADE match the error messages locally when there isn't a correctly configured jupyter_server_config file
• could maybe be something in that jupyter labextension list has a different version of jupyter-fs (0.4.1) than conda list (1.0.0) and what I installed in the environment.yml (1.0.0). But also, jupyter-fs v0.4.1 should still work and even when I directly install 0.4.1 and the versions for conda list and jupyter labextension list match at 0.4.1, the extension still doesn't work. So I am not sure if this is really an issue since 0.4.1 works locally too Does anyone have any other recommendations of things to try? cc @marjo-luc

@batpad @yuvipanda - what library did we decide to try on VEDA for S3 file browsing?
