Hi All:  
I have deploy jupyterhub with k8s and helm.  
I want to specify image name that jupyterhub used to create container. I have asked this for gpt-3, and he gave me code below:

```auto

 def specify_image(spawner):
     spawner.profile_list = []
     spawner.image = 'your_image_name'
 
 c.Spawner.pre_spawn_hook = specify_image

```

But I think these code can not work. Any help? Thanks.

You can specify the image name using `singleuser.image.name` and `singleuser.image.tag`:
