How to Deploy an Ubuntu Linux EC2 Instance in AWS using Terraform

In this story, we will learn how to deploy an Ubuntu Linux EC2 Instance (VM) in AWS using Terraform.

Prerequisite #1: AWS Credentials

Before creating our AWS EC2 Instance, we will need AWS Credentials to execute our Terraform code.

The AWS provider offers a few options of providing credentials for authentication:

• Static credentials
• Environment variables
• Shared credentials/configuration file

For this story, we will use static credentials. Please refer to the “How to create an IAM account and configure Terraform to use AWS static credentials?” story, if you need help to create the credentials.

Note: Using static credentials are great for learning and testing however hard-coded credentials are not recommended in production environments. Never push hard-coded credentials to code repositories.

Prerequisite #2: AWS Key Pair

We will need an AWS Key Pair, consisting of a public key and a private key. The AWS Key Pair is a set of security credentials that we need to connect to an Amazon EC2 instance.
