Overview ¶
Package stacks provides operation for working with Heat stacks. A stack is a group of resources (servers, load balancers, databases, and so forth) combined to fulfill a useful purpose. Based on a template, Heat orchestration engine creates an instantiated set of resources (a stack) to run the application framework or component specified (in the template). A stack is a running instance of a template. The result of creating a stack is a deployment of the application framework or component.
