Install Terraform

Terraform is an open-source Infrastructure as Code (IaC) tool by HashiCorp. It lets you define, provision, and manage cloud and on-premises infrastructure using declarative configuration files.

Ubuntu and its derivatives only — x86_64 architecture only

This script targets Ubuntu-based systems on x86_64 (amd64) hardware. ARM64, RHEL, Fedora, and macOS are not supported by this installer.

Not for production use

This installer is designed for lab and learning environments. For production CI/CD pipelines, pin a specific Terraform version explicitly rather than always resolving the latest.

What Gets Installed

Component Version Location
terraform binary Latest stable (auto-resolved) /usr/local/bin/terraform

Version resolution strategy

The script resolves the latest stable version automatically: 1. Queries the GitHub releases API first 2. Falls back to the HashiCorp releases index if GitHub is unavailable

The resolved version is printed before download begins.

Prerequisites

  • Ubuntu or an Ubuntu-based OS
  • x86_64 (amd64) architecture
  • curl available
  • Run as root or with sudo

Install

curl -fsSL https://raw.githubusercontent.com/ibtisam-iq/silver-stack/main/scripts/installers/install-terraform.sh | sudo bash

Idempotent — safe to re-run

If Terraform is already installed, the script prints the current version and exits without reinstalling.

What the Script Does

  1. Runs preflight checks (OS, connectivity, root access, architecture)
  2. Resolves the latest stable Terraform version from GitHub API (falls back to HashiCorp releases index if GitHub is unavailable)
  3. Downloads the linux_amd64 .zip from releases.hashicorp.com
  4. Installs unzip silently if not present
  5. Extracts the binary, makes it executable, and moves it to /usr/local/bin/terraform

Tip

Run terraform -install-autocomplete after installation to enable shell tab completion for Terraform commands.
