• Deploy a jenkins server on an EC2 instance
• The EC2 instance should be accessible via the internet on port 8080
• Only you should be able to access the EC2 instance via SSH
• Use Terraform for Infrastructure as Code

• Create the VPC
• Create the Internet Gateway and attach it to the VPC using a Route Table
• Create a Public Subnet and associate it with the Route Table
• Create a Security Group for the EC2 Instance
• Create a script to automate the installation of Jenkins on the EC2 Instance
• Create the EC2 Instance and attach an Elastic IP and Key Pair to it
• Verify that everything works

AWS CLI is installed and configured Terraform is installed
