AWS CloudFormation Template for EC2 Instance and Security Group

This repository contains an AWS CloudFormation template for deploying an EC2 instance and a security group. The template is designed to demonstrate basic infrastructure creation using CloudFormation.

Features

• Creates a Security Group that allows all inbound and outbound traffic.
• Deploys a t2.micro EC2 instance with a specified AMI.
• Outputs:
  • The Instance ID of the created EC2 instance.
  • The Public IP address of the EC2 instance.
  • The Security Group ID.

Important Notes

1. Random Placeholder Information:

   • The VPC ID (vpc-0123456789abcdef0) and AMI ID (ami-1234567890abcdef0) in the template are random placeholders and do not correspond to any actual AWS resources.
   • Replace these placeholders with valid IDs from your AWS account before deploying the template.

2. Sensitive Information:

   • No sensitive information is included in this repository.
   • Parameters like VPC ID and AMI ID should be securely managed when deploying the stack.

How to Use

1. Update the Template:

   • Replace the following placeholders with valid values:
     • VpcId: Your actual VPC ID.
     • ImageId: Your actual AMI ID.

2. Deploy Using AWS CLI:

   • Run the following command to deploy the stack:

     aws cloudformation create-stack --stack-name MyStackName \
       --template-body file://template.yaml \
       --parameters ParameterKey=VpcId,ParameterValue=<your-vpc-id> \
                    ParameterKey=AmiId,ParameterValue=<your-ami-id>

3. Verify Outputs:

   • After deployment, review the outputs to get the Instance ID, Public IP, and Security Group ID.
