Variables

Every variables have different properties:

• required: not to be confused with the terraform notion which make any variable without default value required. Here it means required to declare in the detectors templating. These variables could be dormant (empty value) but are declared as terraform variable in the module and this variable is used in the terraform resources.
• scopes: a variable must have, at least, one scope. In case of multiple scopes are supported so there exist different variable for each scope which could override the scope of its "higher version" variable. It could be global, per detector (prefix name with [id]_) or per rule per detector (prefix name with [id]_ and suffix it with _[severity].
• type which refer to terraform type constaints
