Terraform Workflow

In this series, we have been using Terraform by ourselves. We defined the infrastructure - created a plan, created the infrastructure itself and also we saved our code to Github. We had the choice to store and maintain states locally.  However, using Terraform in a team where more than one developer are contributing to the …

Terraform Provisioners

Okay, enough talking about creating cloud resources! We have created a couple of instances using our Terraform code. But, now what? We usually spin up cloud resources for some purpose. When the resources are successfully created, it is rather a start of something. What are provisioners? Cloud resources by themselves are not much of use. …

Terraform Backends

In this post, we discuss backends that can be used with Terraform. Working with backends is essential when a larger team works on developing Terraform code. This is mainly because Terraform relies heavily on states for its operations and there is a huge scope of states getting “corrupted” if we “just use Github” to maintain …

Terraform Data Sources

Data Sources in Terraform is one of the important concepts which enables you to work with data values sourced from somewhere else. Somewhere else here would mean other modules, or cloud providers, or even locally. There are situations where the Terraform code needs to query a “fresh” set of values to be used while applying …

Terraform Modules

Modules are a way to organize Terraform code into re-usable chunks of IaC. Managing code for the complex infrastructure stack in a single go is not a good idea. This is for obvious reasons, the maintenance of the infrastructure itself may become a headache trying to figure out what caused what in lots of lines …

Terraform CLI – Part 2

Now that we have a basic understanding of how Terraform states work, let us take a look at some of the Terraform CLI commands which come in handy to work with the same. We shall also take a look at the significance of these commands and why one should be familiar with them. To refer …

Terraform States

Before we move to the 2nd part of Terraform CLI, I think it is important to discuss Terraform States. This is one of the fundamental concepts while learning to work with Terraform. We will make use of this commit for the example we have been using in this Terraform series. Feel free to clone the …

Terraform CLI – Part 1

Till now we have dealt quite a lot with Terraform CLI directly and indirectly in our previous posts. But Terraform CLI was never the focus of those introductory discussions. If you missed the introduction, please feel free to read the same here. The introductory post also contains information about the workflow (init - plan - …

Terraform Syntax – Part 2

In part 2, we would cover some basics of meta-arguments, expressions, and functions. If you have not read part 1, it is highly recommended to read that part first before proceeding to read this since this part builds upon the example from part 1. Before we proceed, let us first organize our code into multiple …

Terraform Syntax – Part 1

This post is intended to give a brief overview of the configuration syntax of Terraform. We would go through an example and touch up on some of the important aspects of Terraform configuration language, to successfully create an IaC and see that in action. This by no means is an attempt to rewrite all the …
