JupyterHub Zero to JupyterHub on Kubernetes

Hello, members

1. Quetions.

I’m creating a custom image for Z2JH.

When I update the private image, I want to replace the image.
(It means I want to use the new image in Z2JH).
But I don’t know how to force-pull the image.
Does anyone know how to do it?

configuration.

singleuser:
  image:
    name: 'my-private-repository/myjupyterhub'
    tag: 'latest'

Best regards.

You can force Kubernetes to re-pull the image on every start by setting singleuser.image.pullPolicy to Always

Hello, @manics Thank you for your reply.

I’ll try that option.
