How to Install Terraform?

Installation Steps:

Step1:

To install Terraform, first download the Terraform .exe file from: https://www.terraform.io/downloads.html. Ensure you download the correct version based on your system configuration i.e. 32bit/64 bit.

Latest available version of Terraform is v1.15.0. If you happen to have a code that in your environment that you want to reuse it is recommended to check if you are using the same terraform version or a version which ensures backward compatibility.

Step 2:  Once download is complete; you will get a zipped file. Unzip the file to get the .exe file. Copy the .exe file to a folder on your local system directory for e.g.: C:\Users\ipwithease\Terraform.

 

Step3: Next, open your Start Menu and type in “environment” and the first thing that comes up should be Edit the System Environment Variables option. Click on that and you should see this window.

Click on Path under System Variable > Click Edit

Step 4: On the next window Click New & Add the path where you copied your .exe file > Click Ok.

Verification:

Now to verify if the installation has been successful go to Command-Line, change your working directory to the one where you copied the Terraform .exe file and run   “terraform –version”
