 Below, we break down the above command so you can see what each part does:  
                  
  * -vvvv - Make Ansible very verbose.
  * -u heat-admin - Utilize the heat-admin user to connect to the remote machine.
- * -M library/cloud - Sets the module location so the modules load for the playbooks to execute.
  * -i plugins/inventory/heat.py - Sets the inventory plugin.
  * -e nova_compute_rebuild_image_id=1ae9fe6e-c0cc-4f62-8e2b-1d382b20fdcb - Sets the compute node image ID.
  * -e controller_rebuild_image_id=2432dd37-a072-463d-ab86-0861bb5f36cc - Sets the controller node image ID.
