Terraform developer toolkit: In-demand skills, learning resources, online courses, interview prep, books & more

Terraform is a tool, used primarily by DevOps engineers to automate various infrastructure tasks. It’s used mainly for the cloud resources it provides. Learning this tool as a DevOps engineer, you will be able to handle the basic components of applications. Check out this curated article to upgrade your Terraform skills.

Terraform is an infrastructure as a code tool that developers use to define the project resources both on the cloud or on-premise in human-readable configuration files. It makes it easy to reuse and share any code in a native cloud environment. More and more companies are using Terraform to manage the infrastructure and application lifecycle via a consistent workflow. As a DevOps engineer, learning Terraform gives you the skills to handle even the most low-level components of hosted applications like CPU, storage, and networking resources.

Here is a complete Terraform developer toolkit with a list of resources that help you learn, upskill, and prepare for the interviews.

1. Terraform’s Language (HCL): Also called Hashicorp Configuration Language, you must be familiar with the syntax to use Terraform. Here’s an example syntax: 

Terraform_command “provider_resource_name” “resource_name” {

“option_1”: “option_1”,

  “option_1”: “option_1”


When you understand the Terraform code’s basic structure, it becomes much easier to use Terraform. Any Terraform code block has four critical elements: Command, Provider Resource Name, and Options.

2. State: One of the most important concepts of Terraform is the State. As a client-based application, Terraform must be able to keep track of the resources that it creates. For this functionality, it uses the concept of state. You must know how to make a State JSON file and use it for resource optimization.

3. Dependency resolution: Creating a cloud infrastructure requires many resources that are created simultaneously. There is an overlapping dependency between these resources that need management. With Terraform, you can quickly identify which resources depend on each other to prepare a well-planned execution strategy. As a Terraform developer, you must know the concept of dependency resolution, which is extremely important to deploy resource updates in the correct order.

4. Infrastructure as Code: Any DevOps engineer will have to ensure that the systems they design are built in a repeatable manner using Infrastructure as Code. It is an essential skill because it is how you can document cloud objects as version-controlled code. You must learn the concepts of IaC to get better opportunities as a Terraform developer.

Teamwork: DevOps teams work with both developers and operations teams. As part of a DevOps team, you should have a teamwork spirit. Learn to work well with other stakeholders and accommodate their ideas and requirements. Most successful teams are the ones that enable collaboration among members.

Patience: When working as a DevOps engineer, you must have patience. Not everyone will get your idea or the reason behind your decisions immediately. Other developers in your team might need more time to understand things. For this reason, you have to be patient. The operations team might be unable to understand how complex programming is or how long product update releases might take; for such reasons, you should anticipate the need for patience.

Open-mindedness: When you keep your mind open to new ideas, whether yours or someone else’s, you are more approachable and innovative. It would help if you took your time to understand the ideas presented to you before dismissing them. Exploring ideas is how you progress and find new ways to solve a challenge.
