Usage: nomad volume delete [options] <vol id>
|
|
|
|
Delete a volume from an external storage provider. The volume must still be
|
|
registered with Nomad in order to be deleted. Deleting will fail if the
|
|
volume is still in use by an allocation or in the process of being
|
|
unpublished. If the volume no longer exists, this command will silently
|
|
return without an error.
|
|
|
|
When ACLs are enabled, this command requires a token with the
|
|
'csi-write-volume' and 'csi-read-volume' capabilities for the volume's
|
|
namespace.
|
|
|
|
General Options:
|
|
|
|
` + generalOptionsUsage(usageOptsDefault) + `
|
|
|

Delete Options:
|
|
|
|
-secret
|
|
Secrets to pass to the plugin to delete the snapshot. Accepts multiple
|
|
flags in the form -secret key=value
