 Use the [az iot ops delete](/cli/azure/iot/ops#az-iot-ops-delete) command to delete the entire Azure IoT Operations deployment from a cluster. The `delete` command evaluates the Azure IoT Operations related resources on the cluster and presents a tree view of the resources to be deleted. The cluster should be online when you run this command.
