Task 1: Create a security group

To allow traffic to the EC2 instance, you need to create a security group. Follow these steps:

In your main.tf file, add the following code to create a security group:

resource "aws_security_group" "web_server" {
  name_prefix = "web-server-sg"

  ingress {
    from_port   = 80
    to_port     = 80
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }
}

  • Run terraform init to initialize the Terraform project.

  • Run terraform apply to create the security group.

Task 2: Create an EC2 instance

  • Now you can create an EC2 instance with Terraform. Follow these steps:

  • In your main.tf file, add the following code to create an EC2 instance:

resource "aws_instance" "web_server" {
  ami           = "ami-0557a15b87f6559cf"
  instance_type = "t2.micro"
  key_name      = "my-key-pair"
  security_groups = [
    aws_security_group.web_server.name
  ]

  user_data = <<-EOF
              #!/bin/bash
              echo "<html><body><h1>Welcome to my website!</h1></body></html>" > index.html
              nohup python -m SimpleHTTPServer 80 &
              EOF
}

Note: Replace the ami and key_name values with your own. You can find a list of available AMIs in the AWS documentation.

Run terraform apply to create the EC2 instance.

Happy Learning!!
