This function evaluates an attribute within an item in the Terraform configuration. The attribute must either be a top-level attribute or an attribute directly under "config".
This function is contained in the tfconfig-functions.sentinel module.
evaluate_attribute = func(item, attribute)
- item: a single item containing an attribute whose value you want to determine.
- attribute: a string giving the attribute. In general, the attribute should be a top-level attribute of item, but it can also have the form "config.x".
In practice, this function is only called by the filter functions, so the specification of the attribute parameter will be done when calling them.
None.
This function returns the attribute as it occurred within the Terraform configuration. The type will vary depending on what kind of attribute is evaluated. If the attribute had the form "config.x", it will look for "constant_value" or "references" under item.config.x and then whichever one it finds. In the latter case, it will return a list with all the references that the attribute referenced. Note that this does not evaluate the values of the references.
This function does not print anything.
This function is called by the filter_attribute_does_not_match_regex and filter_attribute_matches_regex filter functions in the tfconfig-functions.sentinel module like this:
val = evaluate_attribute(item, attr) else null
