How to install Terraform on Alma Linux 9

In this article, we are going to learn how to install Terraform on Alma Linux 9.

Terraform is an open-source infrastructure as code software tool that provides a consistent CLI workflow to manage hundreds of cloud services. Terraform codifies cloud APIs into declarative configuration files.

Infrastructure as code (IAC) tools allow you to manage your infrastructure with a configuration file rather than through a graphical interface. IAC allows you to build, change and manage your infrastructure in a safe, consistent, and repeatable way by defining configurations that you can version, reuse and share.

Advantages of Using Terraform

• Terraform can manage infrastructure on multiple cloud platforms.
• The human-readable form helps you write infrastructure code quickly.
• Terraforms state helps you to track resource changes throughout your deployments.
• You can commit your configurations to version control to safely collaborate on infrastructure.

Install Terraform on Alma Linux 9.

1. Update system repositories

Before beginning the installation, it is advisable to update your repositories in order to make them up to date.

sudo dnf update -y

After the updates are complete, you need to add the yum-utils package manager to your system first. Yum-utils allows one to add functions without modifying yum-utils code.

sudo yum install yum-utils -y

The sample output will look like this.

[[email protected] ~]# sudo yum install yum-utils -y

2. Add Hashicorp repository

Now we need to tell our system where to get installation packages from and that is by adding the Hashicorp repository to our system repositories. To add repositories, we need to use the following command.

sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo

In order to check whether the Hashicorp repository has been added, use the following command.

sudo dnf repolist

You should see something like this:

repo id                         repo name
appstream                       AlmaLinux 9 - AppStream
baseos                          AlmaLinux 9 - BaseOS
extras                          AlmaLinux 9 - Extras
hashicorp                       Hashicorp Stable - x86_64

3. Install Terraform on Alma Linux 9

After everything is set, we can now install Terraform with the following command.

sudo dnf install terraform -y

The output should look like this.

Hashicorp Stable - x86_64                       690 kB/s | 704 kB     00:01
