Installing Terraform on Linux

As we have already learned how to install Terraform on Windows, now let's learn how to install Terraform on a Linux machine. Then, once we're done with the installation of Terraform, we will learn how we can verify whether a Linux machine has Terraform installed or not. For this section, we have considered an Ubuntu Linux machine; considering multiple Linux platforms such as CentOS, Red Hat, and SUSE is beyond the scope of this book, but in a nutshell, if you know how to install Terraform on one of the Linux platforms, you should easily be able to do so on other Linux platforms too.

Downloading Terraform

Before you start using Terraform, you need to download the appropriate Terraform package for your Linux operating system and architecture. The latest version v1.0 of Terraform is available and can be downloaded from https://www.terraform.io/downloads.html or https://releases.hashicorp.com/terraform/1.0.0/terraform_1.0.0_linux_amd64.zip...
