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unpublished.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
