unregister-host

Description

Unregister a host

Delete a host from the state file. This command will not connect to the host, nor will it perform any operations on its nodes. To destroy an existing cluster and deploy a new one by deleting all data, deleting all nodes, uninstalling all singlestoredb-server packages, and unregistering all SingleStoreDB hosts, use sdb-deploy destroy-cluster.
