Installing Terraform on Ubuntu 22.04: A Step-by-Step Guide

Step 1: Update and Install Required Packages

Ensure that your system is up to date and install the necessary packages:

sudo apt-get update && sudo apt-get install -y gnupg software-properties-common
  • Explanation:

    • apt-get update: Updates the package list to the latest version.

    • apt-get install -y gnupg software-properties-common: Installs the required packages (gnupg, software-properties-common) needed for key management and repository addition.

Step 2: Install HashiCorp GPG Key

Use wget to download HashiCorp's GPG key, dearmor it using gpg, and save it as a keyring file:

wget -O- https://apt.releases.hashicorp.com/gpg | \
gpg --dearmor | \
sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg
  • Explanation:

    • wget -O-: Downloads the GPG key from the specified URL.

    • gpg --dearmor: Converts the GPG key to a binary format.

    • tee /usr/share/keyrings/hashicorp-archive-keyring.gpg: Writes the binary key to the specified file.

Step 3: Verify the Key's Fingerprint

Verify the key's fingerprint using the gpg command:

gpg --no-default-keyring \
--keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg \
--fingerprint
  • Explanation:

    • --no-default-keyring: Prevents the use of the default keyring.

    • --keyring: Specifies the keyring file to use for this operation.

Step 4: Add HashiCorp Repository

Add the official HashiCorp repository to your system using the obtained key:

echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] \
https://apt.releases.hashicorp.com $(lsb_release -cs) main" | \
sudo tee /etc/apt/sources.list.d/hashicorp.list
  • Explanation:

    • Adds the HashiCorp repository information to the system's list of package sources.

Step 5: Download Package Information

Download the package information from the HashiCorp repository:

sudo apt update
  • Explanation:

    • Updates the package information to include the HashiCorp repository.

Step 6: Install Terraform

Install Terraform from the HashiCorp repository:

sudo apt-get install terraform
  • Explanation:

    • Installs Terraform from the newly added repository.

Step 7: Verify Installation

Verify that the installation was successful by checking Terraform's available subcommands:
