Runtime variables are variables that can be modified by the Consumer during the deployment of a Blueprint or after the deployment is complete. They allow the Consumer to customize the attributes of the infrastructure and applications according to their needs. Runtime variables can be defined in the Blueprint settings or in the Blueprint YAML file. They can also be used in the Blueprint tasks to pass dynamic values to the scripts or commands. Runtime variables can be of different types, such as text, number, boolean, list, or password. They can also have default values, constraints, and descriptions to guide the Consumer.
