OpenTofu ​

OpenTofu is a community-driven fork of Terraform. It allows you to define and provision infrastructure using declarative configuration files.

Why OpenTofu? ​

  • Open-source and not vendor-controlled.
  • Compatible with existing Terraform configs.
  • Strong focus on community governance.

Getting Started ​

Install ​

bash
brew install opentofu   # macOS
apt-get install opentofu # Linux (via package repo)
dnf install opentofu # RedHat / Fedora

Basic Usage ​

  1. Initialize a working directory:
bash
tofu init
  1. Validate configuration:
bash
tofu validate
  1. Apply infrastructure:
bash
tofu apply

Example: Provisioning an EC2 Instance ​

hcl
provider "aws" {
  region = "us-east-1"
}

resource "aws_instance" "web" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"

  tags = {
    Name = "opentofu-web"
  }
}

Run:

bash
tofu init
tofu plan
tofu apply
