CloudFormation 从 CodePipeline 传递参数

Question

我有一个 SAM 应用程序和一个用于部署它的 CodePipeline 设置。我想将参数从我的管道向下传递到 SAM 的 YAML 文件中。我尝试使用 ParameterOverrides 但似乎仍然得到：

Parameters: [AppName] must have values (Service: AmazonCloudFormation; Status Code: 400; Error Code: ValidationError; Request ID: 46d1dfd6-9a9a-11e7-a59d-999618d6a174)

我的 sam.yml 参数定义

AWSTemplateFormatVersion : '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Parameters:
  AppName:
    Type: String
    Description: Prefix for resources

定义参数的部分覆盖：

    - Name: ExecuteChangeSet
      Actions:
      - Name: Lambda
        ActionTypeId:
          Category: Deploy
          Owner: AWS
          Version: 1
          Provider: CloudFormation
        Configuration:
          ActionMode: CHANGE_SET_EXECUTE
          ChangeSetName: !Sub
            - '${PipelineName}-lambda'
            - {PipelineName: !Ref PipelineName}
          StackName: !Sub
            - '${PipelineName}-lambda'
            - {PipelineName: !Ref PipelineName}
          ParameterOverrides: !Sub '{"AppName": "${PipelineName}-lambda"}'

这有什么问题吗？

Answer 1

您似乎正试图在 CHANGE_SET_EXECUTE 操作模式期间应用 ParameterOverrides。如果我没记错的话，在幕后，这会映射到没有参数属性的 CloudFormations ExecuteChangeSet 操作。

此问题的解决方案是在创建更改集时应用参数。这将在 CodePipeline 中以 CHANGE_SET_REPLACE 操作模式完成。或者，您可以查看 CREATE_UPDATE。查看 AWS CloudFormation Configuration Properties 了解更多详情。

这是一个创建然后执行更改集的示例

- Name: CreateChangeSet
  Actions:
    - Name: Lambda
      ActionTypeId:
        Category: Deploy
        Owner: AWS
        Version: 1
        Provider: CloudFormation
      InputArtifacts:
        - Name: BuildOutputArtifact
      Configuration:
        ActionMode: CHANGE_SET_REPLACE
        ChangeSetName: !Sub
          - '${PipelineName}-lambda'
          - {PipelineName: !Ref PipelineName}
        StackName: !Sub
          - '${PipelineName}-lambda'
          - {PipelineName: !Ref PipelineName}
        ParameterOverrides: !Ref ProjectParameterOverrides
        TemplatePath: BuildOutputArtifact::SamDeploymentTemplate.yaml
- Name: ExecuteChangeSet
  Actions:
  - Name: Lambda
    ActionTypeId:
      Category: Deploy
      Owner: AWS
      Version: 1
      Provider: CloudFormation
    Configuration:
      ActionMode: CHANGE_SET_EXECUTE
      ChangeSetName: !Sub
        - '${PipelineName}-lambda'
        - {PipelineName: !Ref PipelineName}
      StackName: !Sub
        - '${PipelineName}-lambda'
        - {PipelineName: !Ref PipelineName}
