How to Install Terraform, an Infrastructure as Code (IaC) Tool

Author: Joe Hutcheson

With the increasing complexity of cloud infrastructure, the demand for the open-source, state management tool Terraform is on the rise. Developed by HashiCorp, Terraform gives developers an opportunity to work safely and efficiently through their various clouds using a common coding interface. More and more enterprises are shifting their workloads to cloud environments. Infrastructure as Code (IaC), which is the goal of Terraform, allows these enterprises to manage and provision their environments through code, rather than a manual process.

Getting up and running with Terraform on an Ubuntu/Debian system is easy. First, make sure that your system is up to date wth the following command, which downloads package information from all configured sources:

sudo apt-get update

Now, install the GNU Privacy Guard, the software-properties-common, and the curl packages, which will allow us to verify HashiCorp’s GPG signature and install HashiCorp’s Debian package repository.

sudo apt-get install -y gnupg software-properties-common curl

We need to add the HashiCorp GPG key:

curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -

The following will add the official HashiCorp Linux repository, a source of Debian and RPM packages for HashiCorp products:

sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"

Run the following command again to add the repository:

sudo apt-get update

And finally, this command will install the Terraform CLI:

sudo apt-get install terraform

Check to see that Terraform is installed:

terraform --version

In addition to Ubuntu/Debian, Terraform may be installed on CentOS/RHEL, Fedora, Amazon Linux, Homebrew on OS X, and Chocolatey on Windows. Full install instructions for these platforms are published by HashiCorp within the Terraform documentation pages https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli

And there you go! You’re ready to start exploring the world of Infrastructure as Code with Terraform. Consider doing it with Alta3 Research’s Terraform 101 course!
