This is interesting! How do you get the above CLI?

We currently don’t have a official CLI for Longhorn. We are planning to build one soon. The feature is tracked at [Add Longhorn CLI · Issue #613 · longhorn/longhorn · GitHub](https://github.com/longhorn/longhorn/issues/613)

While waiting for the new CLI, we provide document on how to write Python automation script to controll Longhorn [Longhorn | Documentation](https://longhorn.io/docs/1.1.0/references/longhorn-client-python/)
