Modules are the functions of the Terraform ecosystem. In this episode, we will build a reusable AWS VPC module from scratch, define explicit inputs and outputs, and consume it from a separate Root Module. Stop copy-pasting code and start building a self-service infrastructure catalog.
While ‘count’ and ‘for_each’ duplicate entire resources, ‘dynamic’ blocks duplicate nested configurations inside a single resource. Discover how to build highly flexible, list-driven Security Groups and Route Tables without repeating HCL blocks.
Copy-pasting resource blocks is a cardinal sin in Platform Engineering. In this episode, we will deploy identical infrastructure fleets using loops. You will learn the critical differences between ‘count’ and ‘for_each’, and why ‘count’ can accidentally destroy your production servers if used incorrectly.
Terraform is not just static configuration; it is a powerful programming language. In this episode, we explore how to perform string interpolations, use mathematical functions, and centralize complex expressions using the ’locals’ block to keep your code DRY.
Not everything in your cloud is managed by Terraform. In this episode, you will learn how to use the ‘data’ block to interrogate the AWS API. Fetch the latest Ubuntu AMI ID dynamically, or retrieve a VPC ID created by the Networking team, ensuring your code remains hardcode-free.
Hardcoding values in Terraform is a bad practice. In this episode, we will introduce Input Variables and Data Types to make your code reusable across multiple environments. You will also learn how to extract critical information using Outputs.
It is time to build real infrastructure. In this episode, we will declare an AWS Virtual Private Cloud (VPC) and a Subnet. You will learn how Terraform intelligently determines the correct order of creation using the Dependency Graph, preventing race conditions.
Stop deploying cloud resources manually. In this first episode, we will transform your approach to cloud architecture by introducing declarative IaC. You will learn how Terraform tracks physical resources using the state file, and execute your first local configuration.
