Hi Guys!
Nice to meet you all here.
I have a problem with permissions for user volumes.
They are being created with root:root ownership and user does not have permission to write there.
def create_dir_hook(spawner):
username = spawner.user.name # get the username
volume_path = os.path.join(‘/volumes/jupyterhub/’, username)
print(f"Checking if {volume_path} exists…")
if not os.path.exists(volume_path):
print(f"{volume_path} does not exist. Creating directory...")
# create a directory with umask 0755
# hub and container user must have the same UID to be writeable
# still readable by other users on the system
try:
# Attempt to create the directory
os.mkdir(volume_path)
print(f"Directory {volume_path} created.")
# Now, do whatever you think your user needs
# ...
except OSError as e:
print(f"Error creating directory {volume_path}: {e}")
try:
os.chown(volume_path, 1003, 1003)
print(f"Ownership of changed successfully.")
except OSError as e:
print(f"Error changing ownership of: {e}")
# now do whatever you think your user needs
c.Spawner.pre_spawn_hook = create_dir_hook
I’ve set up pre_spawn_hook to create folder for new user with proper rights (container running with uid 1003), but unfortunately they still are root:root
notebook_dir = os.environ.get("/volumes/jupyterhub/", "/home/jovyan")
c.DockerSpawner.notebook_dir = notebook_dir
c.DockerSpawner.volumes = {'/volumes/jupyterhub/{username}/': '/home/jovyan/work11' ,'/volumes/jupyterhub/test/': '/home/jovyan/test'}
"test" folder also occurs there so I assume it's created in c.DockerSpawner.volumes not pre_spawn_hook.
Could anyone help me?
I would really appreciate this, cause I have overtook project with Jupyter after my colleague and I’m lost now 
I’ve search through all web, but nothing works for me
