Lab 1. Installing OpenTofu

Mon, 01 Jan 0001 00:00:00 +0000

Overview 🔗

In this hands-on activity, we will learn how to install OpenTofu and verify the installation.

Installing OpenTofu 🔗

Linux Environment Setup 🔗

While this section presents various setup options, we will install OpenTofu on an Ubuntu 22.04 host. Depending on the operating system and the installation method, there are several ways to install OpenTofu. The most convenient is to use the installation script provided by the official OpenTofu documentation.

Lab 2. Learning the Basics of OpenTofu

Mon, 01 Jan 0001 00:00:00 +0000

Overview 🔗

In this lab, you will gain hands-on experience with the basics of the OpenTofu command line and be introduced to the OpenTofu configuration language, which specifies the resources OpenTofu would create and the providers it would use.

Prerequisites 🔗

You will need OpenTofu installed as per Lab 1.

Initialize and Create a Local Resource 🔗

In this exercise, we will write a basic OpenTofu code to create a resource locally and understand the basic workflow to create any infrastructure in OpenTofu.

Lab 3. Creating a Virtual Machine using OpenTofu

Mon, 01 Jan 0001 00:00:00 +0000

Overview 🔗

In this lab, you will gain hands-on experience creating a virtual machine from code using OpenTofu. OpenTofu can also create infrastructure across various providers. In this exercise, we will use AWS and create an EC2 instance for demonstration purposes.

Prerequisites 🔗

OpenTofu installed as per Lab 1.
AWS account created - access and secret keys. Note: It is out of scope for this course to help you create an AWS account. Please refer to the official AWS docs (for example, How to create an account and How to configure user).

Creating an EC2 Virtual Machine with OpenTofu 🔗

Create a separate directory for storing your OpenTofu code:

mkdir newproject && cd newproject

Using the editor of your choice, create the file main.tf with the content below:

provider "aws" {
 region = "us-east-1"
 access_key = "xxxxxxxxxxxxxxxxxxxxxxx"
 secret_key = "xxxxxxxxxxxxxxxxxxxxxxxx"
}
resource "aws_instance" "firstvm" {
 ami = "ami-053b0d53c279acc90"
 instance_type = "t2.micro"
 subnet_id = "subnet-xxxxxxxxxx"
}

Note: Please replace the “access_key”, “secret_key” and “subnet_id” with your credentials and subnet ID.
