Terraform, a robust Infrastructure as Code (IaC) tool, empowers users to define and manage infrastructure using declarative configurations. If you're operating on an Ubuntu machine and eager to embark on your Terraform journey, this comprehensive guide will walk you through the step-by-step process of installing Terraform.
Prerequisites:
Before diving into the installation process, ensure that you have the following prerequisites:
Ubuntu Machine: Ensure you have access to an Ubuntu machine.
Terminal Access: Open a terminal on your Ubuntu machine. This is where you'll execute commands for the installation.
Steps to Install Terraform on Ubuntu:
Step 1: Update and Upgrade Packages
Start by updating the package lists and upgrading existing packages to their latest versions. Open your terminal and run the following commands:
sudo apt update
sudo apt upgrade -y
Step 2: Add GPG signature and Repo
Now we need to install the gnupg, software-properties-common, and curl packages. You will use these packages to verify HashiCorp’s GPG signature and install HashiCorp’s Debian package repository.
sudo apt-get install -y gnupg software-properties-common
Install the HashiCorp GPG key:
wget -O- https://apt.releases.hashicorp.com/gpg | \
gpg --dearmor | \
sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg
Verify the key’s fingerprint. The gpg command will report the key fingerprint:
gpg --no-default-keyring \
--keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg \
--fingerprint
Now update your system.
sudo apt update
Step 3: Install Terraform
Now is the time to Install Terraform from the new repository.
sudo apt-get install terraform
Once the installation process completes, check its version using the command:
terraform -v
In the output above, it is clear that the installation of Terraform was successful as it shows an installed version.
Additional Tips:
Updating Terraform:
To update Terraform in the future, repeat the steps above with the latest version's URL. Download, extract, and replace the existing binary with the updated one.
