How you can create an Web Gateway and assign it to an EC2 in CloudFormation

To create an Web Gateway and affiliate it with an EC2 occasion utilizing AWS CloudFormation, you possibly can comply with these steps:

Step 1: Create a CloudFormation template

Create a brand new YAML or JSON file with a .yaml or .json extension (e.g., template.yaml), and add the next contents:

AWSTemplateFormatVersion: "2010-09-09"
Sources:
  MyVPC:
    Sort: AWS::EC2::VPC
    Properties:
      CidrBlock: 10.0.0.0/16  # Change together with your desired VPC CIDR block

  MyInternetGateway:
    Sort: AWS::EC2::InternetGateway

  MyVPCGatewayAttachment:
    Sort: AWS::EC2::VPCGatewayAttachment
    Properties:
      VpcId: !Ref MyVPC
      InternetGatewayId: !Ref MyInternetGateway

  MySubnet:
    Sort: AWS::EC2::Subnet
    Properties:
      VpcId: !Ref MyVPC
      CidrBlock: 10.0.0.0/24  # Change together with your desired subnet CIDR block
      AvailabilityZone: us-west-2a  # Change together with your desired availability zone

  MyRouteTable:
    Sort: AWS::EC2::RouteTable
    Properties:
      VpcId: !Ref MyVPC

  MyDefaultRoute:
    Sort: AWS::EC2::Route
    DependsOn: MyVPCGatewayAttachment
    Properties:
      RouteTableId: !Ref MyRouteTable
      DestinationCidrBlock: 0.0.0.0/0
      GatewayId: !Ref MyInternetGateway

  MyEC2Instance:
    Sort: AWS::EC2::Occasion
    Properties:
      ImageId: ami-0123456789abcdef0  # Change together with your desired AMI ID
      InstanceType: t2.micro  # Change together with your desired occasion kind
      SubnetId: !Ref MySubnet

Be certain that to exchange the placeholder values (CidrBlock, AvailabilityZone, ImageId, and so forth.) together with your desired values.

Step 2: Create a CloudFormation stack

1. Open the AWS Administration Console and navigate to the CloudFormation service.
2. Click on on “Create stack” or “Create a brand new stack” to start out the stack creation course of.
3. Select “Add a template file” and choose the CloudFormation template file you created in Step 1.
4. Proceed by means of the wizard, offering a stack identify and any further configuration choices as wanted.
5. Overview the stack particulars and click on on “Create stack” to start out the stack creation course of.

CloudFormation will now create the web gateway, VPC, subnet, route desk, and EC2 occasion based on the template.

As soon as the stack creation course of completes, your infrastructure might be provisioned, and the EC2 occasion might be related to the web gateway.

It’s vital to have a primary understanding of CloudFormation and AWS ideas when working with CloudFormation templates. Moreover, guarantee that you’ve got applicable permissions and a correctly configured AWS account to create the required assets.
