Usage: nomad volume snapshot create <volume id> [snapshot_name]
|
|
|
|
Create a snapshot of an external storage volume. This command requires a
|
|
volume ID or prefix. If there is an exact match based on the provided volume
|
|
ID or prefix, then the specific volume is snapshotted. Otherwise, a list of
|
|
matching volumes and information will be displayed. The volume must still be
|
|
registered with Nomad in order to be snapshotted.
|
|
|
|
If an optional snapshot name is provided, the argument will be passed to the
|
|
CSI plugin to be used as the ID of the resulting snapshot. Not all plugins
|
|
accept this name and it may be ignored.
|
|
|
|
When ACLs are enabled, this command requires a token with the
|
|
'csi-write-volume' capability for the volume's namespace.

Snapshot Create Options:
|
|
|
|
-parameter
|
|
Parameters to pass to the plugin to create a snapshot. Accepts multiple

|
flags in the form -parameter key=value
|
|
|
|
-secret
|
|
Secrets to pass to the plugin to create snapshot. Accepts multiple
|
|
flags in the form -secret key=value
|
|
|
|
-verbose
|
|
Display full information for the resulting snapshot.
