A stack consists of one or more templates that are run in a particular sequence. When you create a stack, you specify the Heat template and one or more template files that are referred to in the main Heat template.
You can directly input the YAML syntax for the main template or choose a YAML file. You must also specify the values of the parameters mentioned in the main template in the sequence in which they have been listed in the YAML file. Apart from this, you must specify the name of the stack and the timeout in minutes for the stack creation.
You must be a self-service user or an administrator to perform this operation. To create a stack, follow the steps given below.
