Viewing the resources and output of a stack created with Heat

A stack is an orchestrated set of services, where the user launching the stack shouldn't care too much about what IP addresses were assigned. However, the application stack has been launched to serve a purpose and therefore it is helpful to know how to access it! To access the environment, the user interrogates the "outputs" of the stack, which were defined as part of the template. In this example, we are concerned about how to access the website running behind the HAProxy server. The HAProxy server has been assigned a floating IP from the GATEWAY_NET network, and it is assumed that this is how the application will be accessed.

Getting ready

Ensure that you are logged on to a correctly configured OpenStack client and can access the OpenStack environment. Refer to Chapter 2, The OpenStack Client, for details of setting up your environment to use Heat.
