jupyterhub-forwardbasespawner 1.0.7

JupyterHub BaseSpawner class. Enables remote single-user server.

ForwardBaseSpawner

The ForwardBaseSpawner is a base class, which can be used by any Spawner that creats the singleuser notebook server on a remote system. The ForwardBaseSpawner itself cannot start anything. The actual logic of starting / stopping must be implemented in a subclass.

Overview

The JupyterHub ForwardBaseSpawner offers a variety of useful functions, to enable and manage the communication between JupyterHub and a singleuser notebook servers, which runs on a remote machine. It covers the following functionalities:

• Manage ssh port forwarding process from JupyterHub to singleuser notebook server
• Manage ssh port forwarding process from singleuser notebook server to JupyterHub
• Manage Kubernetes Service Resource to make singleuser notebook server reachable for JupyterHub
• Adds cancel function. Allows the user to cancel an ongoing spawn process
• Start process of remote singleuser notebook servers may send their current progress to SpawnEventsAPIHandler, which shows it to the user
• SetupTunnelAPIHandler allows to define the ssh jump node between JupyterHub and singleuser notebook server during the spawn process
• ListServersAPIHandler returns all running UserID-servername combinations. Gives remote systems the chance to compare their running servers with the JupyterHub ones
• SSHNodeRestartedAPIHandler enables a recreation of all port forwarding process to a specific jump node. Required when a jump node was restarted

For more information and the usage have a look at the JupyterHub OutpostSpawner documentation. It's a subclass of the ForwardBaseSpawner and enables a central JupyterHub to start singleuser notebook-server on multiple remote systems.
You can find a few examples and configurations over there.

Requirements

At least one JupyterHub running on a Kubernetes Cluster (recommended is the use of Zero2JupyterHub). A subclass of the ForwardBaseSpawner which implements the actual start/stop logic for singleuser notebook servers.
