TerraForm AWS EC2

To use Terraform to create an AWS EC2 instance, you’ll need to follow these steps:

1. Install Terraform: Make sure you have Terraform installed on your local machine. You can download it from the official website: https://www.terraform.io/downloads.html

2. Set up AWS Credentials: Ensure you have your AWS access and secret keys ready. You can either set them as environment variables or use the AWS CLI to configure them.

3. Create a Terraform Configuration File: Create a file with a `.tf` extension (e.g., `main.tf`) and define your AWS EC2 instance configuration in it.

Here’s an example of a simple configuration to create an AWS EC2 instance:

“`hcl
# main.tf

provider “aws” {
region = “us-west-2” # Replace with your desired AWS region
}

resource “aws_instance” “example” {
ami = “ami-0c55b159cbfafe1f0” # Replace with the AMI ID for your desired OS and region
instance_type = “t2.micro”
key_name = “your-ssh-key-name” # Replace with the name of your SSH key in AWS
}
“`

In this example, we specified the AWS region as “us-west-2,” used a specific Amazon Machine Image (AMI) for “t2.micro” instance type, and set the “key_name” parameter to an existing SSH key pair in your AWS account.

4. Initialize and Apply the Configuration:

Navigate to the directory containing your `.tf` file and run the following commands:

“`bash
terraform init
“`

This command initializes the working directory and downloads the necessary provider plugins.

“`bash
terraform apply
“`

This command will create the AWS EC2 instance based on the configuration defined in the `main.tf` file. It will prompt you to confirm the changes, type `yes`, and then Terraform will proceed with the creation.

After the process completes, Terraform will output information about the created resources, including the public IP address and other details of the newly created EC2 instance.

Remember that this is a basic example, and there are many more configuration options available for AWS EC2 instances in Terraform. You can explore additional parameters and options in the Terraform documentation: https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/instance
