Explanation

The dynamic block is used to construct a collection of repeated nested configuration blocks programmatically. It accepts an iterable (list or map) and generates one nested block per item, avoiding repetitive hardcoded blocks. For example, a dynamic "ingress" block inside an aws_security_group resource can generate multiple ingress rules from a variable list. for_each is a meta-argument for iterating over resource or module instances, not for generating nested blocks within a single resource.
