AWS-EC2-Target-Group-Load-Balancer-Auto-Scaling-Group-Setup-using-CloudFormation

This tutorial outlines the steps to create an EC2 instance, a target group, a load balancer, and an auto scaling group on AWS.

Prerequisites

• AWS account with the necessary permissions.
• AWS Command Line Interface (CLI) installed and configured or Access to the AWS Management Console.

CloudFormation Stack Setup

Step 1: EC2 Instances

Edit ec2-instances.yaml

AWSTemplateFormatVersion: '2010-09-09'
Resources:
  EC2Instance1:
    Type: 'AWS::EC2::Instance'
    Properties:
      ImageId: ami-xxxxxxxxxxxxxxxxx  # Specify your AMI ID
      InstanceType: t2.micro
  EC2Instance2:
    Type: 'AWS::EC2::Instance'
    Properties:
      ImageId: ami-xxxxxxxxxxxxxxxxx  # Specify your AMI ID
      InstanceType: t2.micro

Deploy EC2 Instances

• Using the CLI

aws cloudformation create-stack --stack-name EC2InstancesStack --template-body file://ec2-instances.yaml

• Using the Management Console

1. Open the AWS Management Console.

2. Navigate to the CloudFormation service.

4. Choose Create Stack.

5. In the Select Template section, choose Upload a template file and upload the ec2-instances.yaml file.

7. Choose Next.

8. Enter a stack name (e.g., EC2InstancesStack) and provide any required parameters.

10. Choose Next and follow the on-screen instructions to create the stack.

Step 2: Target Group

Edit target-group.yaml

AWSTemplateFormatVersion: '2010-09-09'
Resources:
  MyTargetGroup:
    Type: 'AWS::ElasticLoadBalancingV2::TargetGroup'
    Properties:
      Port: 80
      Protocol: HTTP
      VpcId: vpc-xxxxxxxxxxxxxxxxx  # Specify your VPC ID

Deploy Target Group

• Using the CLI

aws cloudformation create-stack --stack-name TargetGroupStack --template-body file://target-group.yaml

• Using the Management Console

1. Open the AWS Management Console.

2. Navigate to the CloudFormation service.

3. Choose Create Stack.

4. In the Select Template section, choose Upload a template file and upload the target-group.yaml file.

5. Choose Next.

6. Enter a stack name (e.g., TargetGroupStack) and provide any required parameters.

7. Choose Next and follow the on-screen instructions to create the stack.

Step 3: Load Balancer

Edit load-balancer.yaml

AWSTemplateFormatVersion: '2010-09-09'
Resources:
  MyLoadBalancer:
    Type: 'AWS::ElasticLoadBalancingV2::LoadBalancer'
    Properties:
      Subnets:
        - subnet-xxxxxxxxxxxxxxxxx  # Specify your subnet ID
        - subnet-yyyyyyyyyyyyyyyyy  # Specify your subnet ID
      SecurityGroups:
        - sg-xxxxxxxxxxxxxxxxx  # Specify your security group ID
      LoadBalancerAttributes:
        - Key: idle_timeout.timeout_seconds
          Value: '60'
      Name: MyLoadBalancer

Deploy Load Balancer

• Using the CLI

aws cloudformation create-stack --stack-name LoadBalancerStack --template-body file://load-balancer.yaml

• Using the Management Console

1. Open the AWS Management Console.

2. Navigate to the CloudFormation service.

3. Choose Create Stack.

4. In the Select Template section, choose Upload a template file and upload the load-balancer.yaml file.

5. Choose Next.

6. Enter a stack name (e.g., LoadBalancerStack) and provide any required parameters.

7. Choose Next and follow the on-screen instructions to create the stack.

Step 4: Auto Scaling Group

Edit auto-scaling-group.yaml

AWSTemplateFormatVersion: '2010-09-09'
Resources:
  MyAutoScalingGroup:
    Type: 'AWS::AutoScaling::AutoScalingGroup'
    Properties:
      LaunchConfigurationName: MyLaunchConfig
      MinSize: 2
      MaxSize: 5
      DesiredCapacity: 2
      VPCZoneIdentifier:
        - subnet-xxxxxxxxxxxxxxxxx  # Specify your subnet ID
        - subnet-yyyyyyyyyyyyyyyyy  # Specify your subnet ID

Deploy Auto Scaling Group

• Using the CLI

aws cloudformation create-stack --stack-name AutoScalingGroupStack --template-body file://auto-scaling-group.yaml

• Using the Management Console

1. Open the AWS Management Console.

2. Navigate to the CloudFormation service.

3. Choose Create Stack.

4. In the Select Template section, choose Upload a template file and upload the auto-scaling-group.yaml file.

5. Choose Next.

6. Enter a stack name (e.g., AutoScalingGroupStack) and provide any required parameters.

7. Choose Next and follow the on-screen instructions to create the stack.

Step 5: Clean Up

Delete CloudFormation Stacks

• Using the CLI

aws cloudformation delete-stack --stack-name EC2InstancesStack
aws cloudformation delete-stack --stack-name TargetGroupStack
aws cloudformation delete-stack --stack-name LoadBalancerStack
aws cloudformation delete-stack --stack-name AutoScalingGroupStack

• Using the Management Console

1. Open the AWS Management Console.

2. Navigate to the CloudFormation service.

3. Select the stacks created (EC2InstancesStack, TargetGroupStack, LoadBalancerStack, AutoScalingGroupStack).

4. Choose Delete and confirm the deletion.
