CloudFormation从CodePipeline传递参数

Question

我有一个SAM应用程序和CodePipeline设置来部署它.我想将参数从我的管道传递到SAM的YAML文件中.我试过使用ParameterOverrides但似乎仍然得到:

参数:[AppName]必须具有值(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"}'

这有什么不对吗？

您似乎正在尝试ParameterOverrides在CHANGE_SET_EXECUTE操作模式期间应用。如果我没记错的话，在幕后，这映射到 CloudFormations ExecuteChangeSet操作，它没有 Parameters 属性。

对此的解决方案是在创建更改集时应用参数。这将在具有CHANGE_SET_REPLACE操作模式的CodePipeline 中完成。或者，您可以查看CREATE_UPDATE. 查看AWS CloudFormation 配置属性了解更多详细信息。

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}
