DevOps Tools: Terraform

In this short demo, we’ll create a simple VPC with CIDR Range: 192.168.0.0/24 using Terraform.

Background

Interested in automating infrastructure across any cloud platform? Terraform is your go-to tool.

Terraform is a tool that helps you build, manage, and organize your digital infrastructure in a smooth and automated way. It’s like a wizard for your computer systems, allowing you to create and control your servers, databases, networks, and other components by writing code.

terraform init: Prepares your workspace for applying configurations.
terraform plan: Allows you to preview changes before applying them.
terraform apply: Implements changes as defined by your plan to create, update, or destroy resources.
terraform destroy: Destroys resources created by Terraform if they’re no longer needed.

DevOps Project Outline

Using Terraform To Deploy a VPC with CIDR range: 192.168.0.0/24.

Prerequisite

Install Visual Studio Code.
Install Terraform.
Access to AWS account.

Let’s have fun.

Step 1- Launch Visual Studio Code

Under Explorer, create a new folder named vpc_challenge.
Within that folder, add a new file named main.tf.

Add the script required to create the VPC.

Cheat Sheet: In the script above, ‘provider’ represents the cloud provider, such as AWS. It informs Terraform which services it needs to interact with. ‘Resource’ is one of the fundamental elements in the Terraform language. Each ‘resource’ block describes one or more infrastructure objects, such as a VPC (Virtual Private Cloud). ‘TerraformVPC’ is the name assigned to our VPC that we intend to create. It’s important to remember this name for future reference.
