ok i tried juicefs, sucessfully configure jupyterhub to use juicefs storage class, but there is a complex problem to solve : its not easy to deploy different apps using one and only juicefs storage class, and its not easy to configure jupyterhub to use a different storage class for every new spinned up user. (and if i login with 2 different users in jupyterhub it definitel crashes because the juicefs driver fails volume provisioning to the new spinned up jupyterlab)

So next step: I wil definietly try nfs csi driver, we definetly need to master our kubernetes csi stack

it workssss thanks to yandex's csi driver , just awesome, now one last easy thing:

I just need custom image to be used as notebook

Oh, there's another feature i would certainly want for my kubernetes cluster deployed app, I want date time synchronization:

ok found where to add this c.Spawner.args :

et je dois donc faire un generate config avec la commande jupyter lab ça va me le générer dans le répertoire ~/.jupyter/jupyter_config.py

un truc du genre à vérif mais c'est ça c'est sûr

ah oui mais non en fait c'est de la config du jupyterhub lui pas dans mon image docker, c'est la commande jupyterhub https://jupyterhub.readthedocs.io/en/0.7.2/getting-started.html#technical-overview

Jean-Baptiste-Lasselle commented 1 month ago

I am searching how to integrate :

There I want to note : 

~$ docker exec -it d5272d1e503a bash -c 'jupyter lab --help-all | grep auth'
    The full path to a certificate authority certificate for SSL/TLS client
    authentication.
--ServerApp.allow_unauthenticated_access=<Bool>
    Allow unauthenticated access to endpoints without authentication rule.
            in the future), any request to an endpoint without an authentication rule
            (either `@tornado.web.authenticated`, or `@allow_unauthenticated`)
            excluding the endpoints marked with `@allow_unauthenticated` decorator.
            prevent unauthenticated access to endpoints without `@allow_unauthenticated`.
--ServerApp.authenticate_prometheus=<Bool>
            Require authentication to access prometheus metrics.
--ServerApp.authorizer_class=<Type>
    The authorizer class to use.
    Default: 'jupyter_server.auth.authorizer.AllowAllAuthorizer'
    The full path to a certificate authority certificate for SSL/TLS client
    authentication.
            the actual connection URL. If authentication token is enabled, the
            - authenticate with a token
            completely without authentication.
            These services can disable all authentication and security checks,
    Default: 'jupyter_server.auth.identity.PasswordIdentityProvider'
    Default: 'jupyter_server.auth.login.LegacyLoginHandler'
    Default: 'jupyter_server.auth.logout.LogoutHandler'
         prevented the authentication token used to launch the browser from being visible.

So there one idea might be :

And with those re-definitions, I do so that the Authhentication flow handled by JupyterHub is compatible with the authentication endpoint of my server in my docker image.

I still have the feeling that there is osmething wrong about all this:

the volumes are mounted with root ownship, which is bothering, because for example, some jupyterlab extension can't work, like the jupyter-git extension.

ok i found more about this issue :

other interesting things:

  • Can't change directory permissions or ownership via s3fs minio/minio#6496

  • Oh Ok, i have real answers about my issue with the volume mounts there :

    • s3fs and rclone support yandex-cloud/k8s-csi-s3#16
    • others than GeeseFS have major issues like being slow, being hard to setup, etc
    • now i remember it worked like a charm real well in one case for me: when i used root user to run my jupyter. So can i modify my docker image to run with root user (in which case i'll have to add the --allow-root arg to the notebook) ? Will it be a problem for the jupyterhub ? I'll have then to mount my volume anywhere i want actually like on /opt/jupyterlab/workspace , for example, it's only then that the jupyter extensions will work well, yet,it would be a security issue, wouldn't it...?
    • what can i do to solve the issue well? GeeseFS only works well with Yandex s3, so does that mean that if i cahnge the s3 backend (minio), for anothe, i might solve my issue..? not sure at all...
    • Oh, actually it is Yandex themselves who implemented GeeseFS and the subtitle of the repo makes it clear they had a hard time with other s3 filesystem to have good POSIX compatibility... : Finally a good POSIX-ish FUSE s3 filesystem written in go : This is why here I don't think i will go much further than where i got, with this issue except by using either a root user inside my containers (but then i'll have to harden security a lot for production), or I haev to switch to a non s3 CSI driver . In case i run with root user inside contianer, i would at least try and provision the whole stack by running containers with podman and without running the containers runtime daemon as root (is it possible to run as rot inside container if container runtime is not executed as root ? Im not sure there)
  • my conclusion is i definitely will have to find full posix support csi driver not based on s3: would NFS csi drivers do ? i don't like the idea of using NFS, so perhaps ceph with block storage and not s3. Yet it still is a problem this issue about having s3 buckets monted necessarily as root in pod containers... )

THE NEXT TEST: I'll try OpenEBS (not iSCSI csi driver)

https://openebs.io/docs/quickstart-guide/installation

yes definitely OpenEBS it's the best i found there for now, i give a quick try and:

this was the first thing i thought of about block storage csi driver:

Okay i want to provision in my cluster an iSCSI csi driver:
