DockerSpawner volume parameter

[Maria Julia Lima]

Hello

I am a beginner in Jupyterhub and I am investigating an integration of a web application to Jupyterhub. This application has its on file repository and each user has access to its on path. I have implemented an Authenticator that receives a query parameter with the user's path and I would like to transfer this path to the DockerSpawner in order to be used as the volume parameter for the container. 

If someone could give me a suggestion that would be great.

Thanks in advance.

Authenticator.pre_spawn_start might be what you are after. It’s called prior to each Spawner starting.

def pre_spawn_start(self, spawner):
    user = spawner.user
    volumes = self.volumes_for_user(user.name)
    spawner.volumes.update(volumes)

Many thanks, Min.

My authenticator uses a customized handle that processes the query parameters received from the http request. 

Can the authenticator have access to this handle reference?

 

By the way, I implemented a solution using user.auth_state and it works.

It can be passed the Handler during authenticate, but not during spawn. This is exactly what auth_state is for - Authenticators saving info during authentication to pass to spawn. I'm glad you got it working!
