Terraform is an open-source infrastructure as code software tool created by HashiCorp. Users define and provision data Center infrastructure using a declarative configuration language known as HashiCorp Configuration Language, or optionally JSON.
Terraform codifies cloud APIs into declarative configuration files. This enables infrastructure automation workflows that describe the desired state of infrastructure as code, and then apply the desired state to real resources.
Terraform can manage infrastructure on many different public and private cloud providers, as well as on-premises systems.
Here are some of the benefits of using Terraform:
● Efficiency: Terraform can help you to automate the provisioning of infrastructure, which can save you some and money.
● Consistency: Terraform can help you to ensure that your infrastructure is consistent across environments, which can help to improve reliability & security.
● Reliability: Terraform can help you to create infrastructure that is reliable and can withstand failures.
● Security: Terraform can help you to create infrastructure that is secure and compliant with your security policies
Installing Terraform on MacOS is possible via the zipped file with the Terraform binary and via the official HashiCorp repository. The repository contains other non-Terraform HashiCorp products you can install later.
brew tap hashicorp/tap
brew install hashicorp/tap/terraform
To install Homebrew on your Mac, you can use the following command in your terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
This command will download and run the installation script for Homebrew. The script will explain what it will do and then pause before it does it. You will be asked to confirm everything it will do before it starts.
You can also find more information about Homebrew on their homepage or on their documentation page.
