Automating an EC2 instance deployment

Let’s take a look at an example Terraform configuration file that will allow us to build an EC2 instance:

provider "aws" {
    region = "us-east-1"
}
resource "aws_instance" "my-server-1" {

    key_name                              = "jay_ssh"
    vpc_security_group_ids                = [ "sg-0597d57383be308b0" ]
    tags = {
        Name = "Web Server 1"
    }
}

Terraform files are saved with a .tf filename extension, and as for the actual name, you can call it whatever you wish. I named mine terraform_example_1.tf. The underscores in the filename aren’t required but make it easier to use on the command line since you won’t have to escape spaces. I placed...
