要在CloudFormation中使用CodeDeploy蓝绿部署创建堆栈，需要在AWS CodePipeline中创建包含CodeDeploy蓝绿部署的流水线。然后，使用AWS CloudFormation模板调用该流水线。以下是一个例子：

在CodePipeline中创建具有“CodeDeploy Deployment”阶段的流水线。

示例CloudFormation模板：

{
   "AWSTemplateFormatVersion" : "2010-09-09",
   "Resources" : {
      "CodePipeline" : {
         "Type" : "AWS::CodePipeline::Pipeline",
         "Properties" : {
            "ArtifactStore" : {
               "Location" : "artifact-store-bucket",
               "Type" : "S3"
            },
            "Name" : "my-pipeline",
            "RoleArn" : "pipeline-role-arn",
            "Stages" : [
               {
                  "Actions" : [
                     {
                        "ActionTypeId" : {
                           "Category" : "Source",
                           "Owner" : "AWS",

                           "BranchName" : "master"
                        },
                        "Name" : "Source",

                        "RunOrder" : 1
                     } 
                  ],
                  "Name" : "Source"
               },
               {
                  "Actions" : [
                     {
                        "ActionTypeId" : {
                           "Category" : "Deploy",
                           "Owner" : "AWS",
                           "Provider" : "CodeDeployToLambda",
                           "Version" : "1"
                        },
                        "Configuration" : {
                          "ApplicationName": "my-codedeploy-app",
                          "DeploymentGroupName": "my-deployment-group",
                          "Version": { "Ref": "LambdaVersion" }
                        },
                        "InputArtifacts" : [ {
                           "Name" : "source-code"
                        } ],
                        "Name" : "CodeDeployLambda",
