Using loops in Terraform can be very powerful. It can take messy spaghetti code and turn it into something clean, simple, and easily understandable. It can make infrastructure scalable and efficient with just a few lines of code. The HCL language is both human-readable and machine-friendly, where components and lists can be iterated to create looping logic. Loops are commonly used in the Terraform community to make modules dynamic. For example, a Virtual Machine module can use loops to deploy multiple disks if needed or contain multiple IP addresses.
In this lab, you will create a NSG Module that contains loops using several methods in Terraform.
Upon completion of this lab you will be able to:
