Infrastructure as Code quickly became standard in industry.

Using tools like Terraform, you can create and destroy the whole infrastructure by running a few commands only.

Let’s see how we can create the following configuration using Terraform:

• Create an EC2 Linux instance.
• Install Docker on an EC2 instance.
• Run Jenkins on Docker and print the public IP.
• Access Jenkins from your browser.

Prerequisites:

• AWS account.
• Install AWS CLI.
• Install Terraform.
• AWS associated credentials that allow you to create resources.
• You can also read the AWS Get Started Terraform manual.
