Accessing Terraform modules from a separate repository enhances the modularity, reusability, and centralized maintenance of infrastructure code. By linking modules to a primary Terraform directory via HTTPS or SSH, you can ensure that modules are maintained and updated in one location, reducing redundancy and ensuring consistency.
This discussion demonstrates the use of dynamic blocks in Terraform to create Azure Front Door routing rules. It defines a map of routing rules in the terraform.tfvars file, where each rule includes attributes like accepted protocols, patterns to match, and frontend endpoints. The dynamic block is used to iterate over these routing rules and generate configuration blocks for each rule dynamically. In the case of forwarding rules, another nested dynamic block is used to configure forwarding settings.
