In Docklet, each user has their own persistent Dataspace, in which to save data files. Dataspaces are isolated from each other, each user can only visit their own Dataspace.
User's Dataspace is shared among all nodes of their vcluster. It is
located in the
~/nfs directory of the container node.
When the user save their Workspace as image, the Dataspace will be excluded.
The Dataspace is supported by distributed file system in the backend. Except the Dataspace, all data in containers will be destroyed as the containers are deleted. But the data in Dataspace will be persistent regardless of the lifecycle of containers.
Users are encouraged to download and backup their important data in time.
