HCL Language Features with Terraform

This task involves utilizing various HCL language features such as count, for_each, Terraform lifecycle, dynamic blocks, and built-in functions.

Prerequisites

• Basic understanding of Terraform and Azure.
• Terraform installed on your machine.
• Azure CLI installed and configured.

Hands-on Task

1. Fork this repository.
2. Create multiple instances of a resource using the count meta-argument.
3. Create multiple network interfaces using the for_each meta-argument.
   • Add a resource block that creates multiple network interfaces using for_each.
   • Use a local value to define a list of network interface names.
   • Iterate over the list using for_each to create the resources.
4. Add a lifecycle block to prevent accidental virtual machine resource deletion.
5. Add dynamic blocks for network security rules.
   • Define a list of network security rules in a local value.
   • Use a dynamic block to iterate over the list and create the security rules.
6. Use built-in functions to manipulate strings and other data.
   • Create an output block that converts the virtual machine name to uppercase.
   • Create an output block that joins multiple tag values into a single string.
   • Create an output block that uses a for loop to get the IDs of all virtual machines.
7. Organize the Terraform code into multiple files for better readability and maintenance.
