Terraform: Installation guide for beginners


Terraform is a tool for building, changing and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solution. 

We need to install the following packages if not installed already:

#yum install unzip -y

#yum install wget -y

2: Go to the to check the latest available version to download,in my case latest available version is 0.11.7 


2.1: Let’s extract the downloaded zip terraform package:

2.2: Copy the extracted file to /usr/loacl/sbin and verify terraform installed version

3: Here we have installed terraform on linux box, let’s apin up first our Ec2 instance using terraform. First we need to setup the aws provider by creating the 3files-, and terraform.tfvars => This will configure the provider for aw, it uses string interpolation to pull variable from file. => This file is typically full of environment specific configuration.

terraform.tfvars => This file will pass into each command and provides the secret and more specific values.

Run the “terraform init” command to initialize the provider plugins:

Once this check is passed, we are good to create our first terraform code to launch an Ec2 instance in aws:

We are using basic specification just to test the setup:

Let’s verify the written code by “terraform plan” command:

As we did not see any error while executed “terraform plan” command so we are good.

Let’s not wait anymore and spin up the instance using “terraform apply” command:

Yes, so here we have launched our first Ec2 Instance using terraform.
