The first (and only) thing we need to do is configure a CloudFront distribution as shown in the following diagram:

1. Create a new CloudFormation template and add the following code:

      AWSTemplateFormatVersion: '2010-09-09'
      Parameters:
        OriginDomainName:
          Description: The hostname of your origin
           (i.e. www.example.org.s3-website-ap-southeast-2.amazonaws.com)
          Type: String
        Aliases:
          Description: Comma delimited list of aliases
           (i.e. example.org,www.example.org)
          Type: CommaDelimitedList
      Resources:
        DistributionALogBucket:
          Type: AWS::S3::Bucket
        DistributionA:
          Type: AWS::CloudFront::Distribution    
          Properties:
            DistributionConfig:
              Origins:
              - DomainName:
                  Ref: OriginDomainName
                Id: OriginA
                CustomOriginConfig:
                  OriginProtocolPolicy: http-only
              Enabled: true
              Logging:
                IncludeCookies: false
                Bucket:
                  Fn::GetAtt: DistributionALogBucket.DomainName
                Prefix: cf-distribution-a
              Aliases:
                Ref: Aliases
              DefaultCacheBehavior:
                TargetOriginId: OriginA
                ForwardedValues:
                  QueryString: false
                ViewerProtocolPolicy: allow-all
              PriceClass: PriceClass_100
      Outputs:
        DistributionDomainName:
          Description: The domain name of the CloudFront Distribution
          Value:
            Fn::GetAtt: DistributionA.DomainName
        LogBucket:
          Description: Bucket where CloudFront logs will be stored
          Value:
            Ref: DistributionALogBucket

2. Using the template we created above, go ahead and create your CloudFront distribution. Expect to wait around 20-25 minutes for this stack to finish creating. It takes a while for your distribution configuration to be pushed out to all the AWS CloudFront locations:

        aws cloudformation create-stack  
          --stack-name cloudfont-cache-1  
          --template-body file://03-caching-a-website.yaml   
          --parameters  
          ParameterKey=OriginDomainName,ParameterValue=<your-domain-name>  
          ParameterKey=Aliases,ParameterValue='<alias-1>,<alias-2>'
