Usage: nomad volume create [options] <input>
|
|
|
|
Creates a volume in an external storage provider and registers it in Nomad.
|
|
|
|
If the supplied path is "-" the volume file is read from stdin. Otherwise, it
|
|
is read from the file at the supplied path.
|
|
|
|
When ACLs are enabled, this command requires a token with the appropriate
|
|
capability in the volume's namespace: the 'csi-write-volume' capability for
|
|
CSI volumes or 'host-volume-create' for dynamic host volumes.
