dynamic rule generation

In Terraform, dynamic blocks help automate the generation of multiple instances of a block for a variable list of configurations. In this example, a dynamic block is used to define Azure Security Group rules dynamically based on a list of virtual network rules. The rules are defined in a list of objects, and Terraform creates individual security rules for each item. This approach simplifies the management of infrastructure and ensures consistency. The variables are defined in a variables.tf file, and the configurations are applied using terraform plan and apply.
