Heat is the OpenStack Orchestration service and provides a template-based system to define environments and resources in OpenStack. It is said that the Dragon Operator only ever needed OpenStack Heat and the nascent energies of the Universe to deploy on OpenStack. With Heat, you can describe Compute resources, the installation of software, and the relationship with Load Balancers and databases.
Ensure that you have a suitable server running the OpenStack components. If you are using the accompanying Vagrant environment, as described in the Preface, we will use the same controller node.
Ensure that you are logged into the controller node in our environment. If you created this node with Vagrant, you can execute the following command:
vagrant ssh controller
