Ask quick dev questions about JupyterHub, the multi-user server for Jupyter notebooks. Use discourse.jupyter.org for user questions, support, and discussion.
Nice! Great to know the scaling capabilities @yuvipanda . Do you have endpoints exposed for metrics on the hub process? I see CHP is a separate process through ps auxf

Hi all.
I'm setting JupyterHub on Kubernetes, using KubeSpawner. All is fine with standard images, but I want to customize more to fit our needs (and maybe use nbgrader).
I want to set homeMountPath with different value depending on the image selected by the user.
I have a config file like:
...
hub:
extraConfig:
spawner: |
profiles = [
{
'display_name': "Image 1",
'description': "Standard image, with Python kernel.",
'kubespawner_override': {
'image': 'my-custom-image-1',
},
{
'display_name': "Image 2",
'description': "Another image, with Python and R kernel.",
'kubespawner_override': {
'image': 'my-custom-image-2',
},
},
def populate_options(self):
self.profile_list = profiles
return self._options_form_default()
c.KubeSpawner.options_form = populate_options
...
singleuser:
storage:
homeMountPath: /home/someuser
...for the default mount point. For some image, like for example with Image 2,
I want to use /home/anotheruser instead. I have try with this code for the Image 2 part:
{
'display_name': "Image 2",
'default': True,
'description': "Another image, with Python and R kernel.",
'kubespawner_override': {
'image': 'my-custom-image-2',
'storage': {
'home_mount_path': '/home/anotheruser',
},
},
},without success. The user home is always mounted on '/home/someuser'. I also have try with 'homeMountPath' instead of 'home_mount_path', and it's the same, it's
What is the correct way to configure it? Is it possible?
volume_mounts and volumes. See https://jupyterhub-kubespawner.readthedocs.io/en/latest/spawner.html
{
'display_name': "Image 2",
'default': True,
'description': "Another image, with Python and R kernel.",
'kubespawner_override': {
'image': 'my-custom-image-2',
'volume_mounts': {
'name': 'volume-{username}'
'mount_path': '/home/anotheruser',
},
},
},@chicocvenancio: thanks for the tip. I have try with something like:
...
{
'display_name': "Image 2",
'description': "Another image, with Python and R kernel.",
'kubespawner_override': {
'image': 'my-custom-image-2',
'volume_mounts': c.KubeSpawner.volume_mounts + [{
'name': 'volume-{username}',
'mount_path': '/home/anotheruser',
}],
},
},
...and now, I have the two monts /home/someuser and /home/anotheruser. I will make a replace of /home/someuser with /home/anotheruser instead, and it should do what I want. Thanks.
PS. at the same time, I have an answer for another question I'm trying to solve: how to add different mounts for different images. I was trying with extraVolumes and extraVolumeMounts, but doing it directly on volume_mounts and mounts seems to be the right way to go. Thanks a lots.
.ssh folder get changed to 660 which is too open for the Ursa_key. What is the recommended way to have user-permissions be "persistent"? Thank you!
