Overview

A demo of Terraform vs CloudFormation

Terraform Demo

Let's now run Terraform.

Create an S3 Bucket with Terraform

1. The Terraform configuration is found in the TerraformS3.tf file and is written in HCL (HashiCorp Configuration Language).

2. Make sure you have the Terraform binary installed on your machine.

3. Run the following commands to create an S3 bucket with Terraform:

terraform init
terraform plan
terraform apply

Destroy the S3 Bucket with Terraform

Run the following command and accept the prompt to destroy the S3 bucket:

terraform destroy

CloudFormation Demo

Create an S3 Bucket with CloudFormation

To deploy a CloudFormation template (written in YAML or JSON), you can use the AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs. Below are the steps for deploying your CloudFormation template using the AWS Management Console and AWS CLI:

1. Prepare Your Template: Ensure your YAML file is ready and accessible.
2. Install the AWS CLI: If you haven't already, install the AWS CLI and configure it with your AWS credentials.
3. Deploy the Stack: Open your terminal or command prompt. Use the aws cloudformation create-stack command to deploy your template. You'll need to specify the stack name and the path to your YAML file. Here's an example command:

aws cloudformation create-stack --stack-name env0-demo-cloudformation-stack --template-body file://CloudFormationS3.yaml

Output:

{
    "StackId": "arn:aws:cloudformation:us-east-1:706933696988:stack/env0-demo-cloudformation-stack/fcaa0880-c209-11ee-81a7-1272e2b5acdf"
}

4. Monitor the Stack Creation: You can monitor the progress of your stack creation in the AWS Management Console under the CloudFormation service, or by using the AWS CLI command:

aws cloudformation describe-stacks --stack-name env0-demo-cloudformation-stack

Output:

{
    "Stacks": [
        {
            "StackId": "arn:aws:cloudformation:us-east-1:706933696988:stack/env0-demo-cloudformation-stack/fcaa0880-c209-11ee-81a7-1272e2b5acdf",
            "StackName": "env0-demo-cloudformation-stack",
            "CreationTime": "2024-02-02T20:39:53.044000+00:00",
            "RollbackConfiguration": {},
            "StackStatus": "CREATE_COMPLETE",
            "DisableRollback": false,
            "NotificationARNs": [],
            "Tags": [],
            "EnableTerminationProtection": false,
            "DriftInformation": {
                "StackDriftStatus": "NOT_CHECKED"
            }
        }
    ]
}

Destroy the CloudFormation Stack

Run the following command:

aws cloudformation delete-stack --stack-name env0-demo-cloudformation-stack

You won't get any output, but once again you can check the status with the command:

aws cloudformation describe-stacks --stack-name env0-demo-cloudformation-stack

Output:

An error occurred (ValidationError) when calling the DescribeStacks operation: Stack with id env0-demo-cloudformation-stack does not exist
