Install Terraform on Mac with Homebrew (brew install terraform)

Introduction

Terraform, developed by HashiCorp, is a popular open-source infrastructure as a code software tool that enables you to build, change, and version infrastructure efficiently. Here's a comprehensive guide to installing Terraform on a macOS system.

Prerequisites

• macOS operating system
• Homebrew package manager installed

Step-by-Step Installation

1. Open Terminal

First, open the Terminal app on your macOS. You can find it in the Utilities folder inside the Applications folder.

2. Add the HashiCorp Tap

Run the following command in the Terminal to add the HashiCorp tap, a repository of all HashiCorp formulae for Homebrew:

brew tap hashicorp/tap

This command clones the HashiCorp repository into Homebrew's directory and prepares it for installing Terraform.

3. Install Terraform

To install Terraform, use the following command:

brew install hashicorp/tap/terraform

Homebrew will fetch the Terraform package and install it on your macOS device. During this process, you'll see the progress of the download and installation.

==> Fetching hashicorp/tap/terraform\
==> Downloading https://releases.hashicorp.com/terraform/1.7.2/terraform_1.7.2_darwin_arm64.zip\

4. Verify the Installation

After the installation is complete, you can verify it by running:

terraform --version

This command will display the installed version of Terraform, confirming the successful installation.

Terraform v1.7.2
on darwin_arm64

5. Enable Autocomplete (Optional)

For a better command-line experience, Terraform provides an autocomplete feature. To enable it, run:

terraform -install-autocomplete

Restart your Terminal for the autocomplete feature to take effect.

Updating Terraform

To keep Terraform up-to-date, you can use Homebrew to upgrade it to the latest version:

brew upgrade hashicorp/tap/terraform

If Terraform is already at the latest version, Homebrew will notify you.
