Hub Volume Mounts

Volume mounts allow a user to access file system data from within their JupyterHub server. Volume mounts can either be data that is locally available on the Kubernetes node running the server or an external NFS mount.

Adding or Editing Images

To add a new mount, click the + New Mount button. Alternatively, to edit or delete an existing mount, click on its name in the table. When creating a mount, select a Mount Type of either Host Path or NFS.

Configuring a Host Path Mount

A Host Path mount is a Notebook Server mount to a file system location on the node that is hosting the server. For host paths to be available as mount options, they must be configured by TACC staff. If you would like a new host path mount, you must file a ticket requesting the host path before making configuration changes in the Administration Portal.

The Remote Server option is disabled for Host Path mounts. The Path option is the file system path on the host node that will be mounted. The Mount Path option is the path as it appears in a user’s Notebook server. The Read Only option restricts a user’s Notebook server write access to that path.

Configuring an NFS Mount

An NFS mount is a Notebook Server mount to a remote file system that has been exported via NFS. If you would like to configure an NFS mount, you must file a ticket to verify that an NFS export has been configured before making configuration changes in the Administration Portal.

The configuration options here are similar to those available when configuring a Host Path mount, except that you may now specify an address for the Remote Server. It does not need to be prefixed with nfs://.
