使用 AWS CodePipelines 部署无服务器转换

Question

我根据this CloudFormation Template 设置了一个管道。

当我尝试部署使用 AWS SAM 的模板时，管道中出现错误

动作执行失败 CreateStack 不能与包含变换的模板一起使用。 （服务：AmazonCloudFormation；状态代码：400；错误代码：ValidationError；请求 ID：167007a4-7672-11e8-8f67-67e79ae9de20）

这主要是抱怨我的动作模式，

Configuration:
  ActionMode: CREATE_UPDATE

我可以使用 Pipeline Code Build stage，它使用 AWS CLI cloudformation 包 like this，

version: 0.1
phases:
  install:
    commands:
      - npm install time
      - aws cloudformation package --template-file samTemplate.yaml --s3-bucket bucket-name 
                                   --output-template-file outputSamTemplate.yaml
artifacts:
  type: zip
  files:
    - samTemplate.yaml
    - outputSamTemplate.yaml

但我宁愿使用预先构建的东西。如何使用 CodePipelines 部署无服务器转换 Cloudformation 模板？我可以不使用 AWS CLI 打包和部署模板吗？

启动 CodeStar Python 项目给了我答案。值得注意的是，他们在部署阶段有两个 Cloudformation 操作，分别执行 CHANGE_SET_REPLACE 和 CHANGE_SET_EXECUTE。

从CF模板中去除无关信息，可以看到里面的动作结构，

Resources:
  ...
  ProjectPipeline:
    Type: 'AWS::CodePipeline::Pipeline'
    Properties:
      Stages:
        -
          Name: Deploy
          Actions:
            - Name: GenerateChangeSet
              ActionTypeId:
                Provider: CloudFormation
              Configuration:
                ActionMode: CHANGE_SET_REPLACE
            - Name: ExecuteChangeSet
              ActionTypeId:
                Provider: CloudFormation
              Configuration:
                ActionMode: CHANGE_SET_EXECUTE

以下是管道的完整模板资源。使用与上面相同的buildspec.yml，他们的 CodePipeline 模板看起来像，

    Type: 'AWS::CodePipeline::Pipeline'
