unregister-host

Unregister a host

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 delete all data, delete all nodes, uninstall all `singlestoredb-server` packages, and unregister all SingleStoreDB hosts, use `sdb-deploy destroy-cluster` (e.g., to destroy the existing cluster and deploy a new one).

Usage:
  sdb-toolbox-config unregister-host [flags]

Flags:
  -a, --all           Unregister all hosts
  -h, --help          Help for unregister-host
      --host string   The host to unregister

  -y, --yes                                   Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default
