SwarmSpawner Persistence of user notebook directories error

See original GitHub issue

I use add the lines below in

notebook_dir = os.environ.get('DOCKER_NOTEBOOK_DIR') or '/home/jovyan/work' c.DockerSpawner.notebook_dir = notebook_dir c.DockerSpawner.volumes = { 'jupyterhub-user-{username}': notebook_dir }

It is use to persist user notebook directories. And got an error:

Incompatible options have been provided for the bind

I spent a lot of time to resolve issue with not working volumes with SwamSpawner. Finally I resolved it by:

  • mounting NFS storage on each node,
  • bind NFS volume to JupyterHub container
  • create user volume on NFS storage by Spawner.pre_spawn_hook by following code snippets:
def create_dir_hook(spawner):
    username =  # get the username
    volume_path = os.path.join('/nfs/path/dir', username)
    if not os.path.exists(volume_path):
        os.mkdir(volume_path, 0o755)
    mounts_user = [
                   {'type': 'bind',
                    'source': '/nfs/path/dir/' + username,
                    'target': '/home/jovyan/work', }
    spawner.extra_container_spec = {
        'mounts': mounts_user

# attach the hook function to the spawner
c.Spawner.pre_spawn_hook = create_dir_hook

I know it is workaround but is only way to attach user directory in SwarmSpawner mode.

@sangramga Thanks for replying! I tryed it, but still got the error. After reading the code of SwarmSpawner, I found that maybe there may be a problem here: 2018-07-27 3 03 50

driver_config (DriverConfig): Volume driver configuration. Only valid for the volume type.

But our type is “bind” here.
