CodeBuild无法创建日志



我在我的CodeBuild服务中具有以下角色，通过CloudFormation生成

  CodeBuildRole:
    Type: AWS::IAM::Role
    Properties:
      RoleName: !Sub '${PipelineName}-codebuild'
      AssumeRolePolicyDocument:
        Version: '2012-10-17'
        Statement:
          Effect: Allow
          Principal:
            Service: codebuild.amazonaws.com
          Action: sts:AssumeRole
      Policies:
        - PolicyName: !Sub '${PipelineName}-codebuild'
          PolicyDocument:
            Version: '2012-10-17'
            Statement:
              - Effect: Allow
                Resource:
                - !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}'
                - !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}/*'
                Action:
                - 'logs:CreateLogGroup'
                - 'logs:CreateLogStream'
                - 'logs:PutLogEvents'
              - Effect: Allow
                Resource:
                  - !Sub 'arn:aws:s3:::codepipeline-${AWS::Region}-*/*'
                Action:
                  - 's3:GetObject'
                  - 's3:GetObjectVersion'
                  - 's3:PutObject'
              - Effect: Allow
                Resource:
                  - !GetAtt [PipelineArtifactStore, Arn]
                Action:
                  - 's3:PutObject'

有什么问题 
- !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}'
- !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}/*'

为什么CodeBuild不能写日志？

看来，您要赋予的角色的价值与预期的价值之间可能有微小的区别。

看来，您正在基于${PipelineName}-codebuild的名称创建角色，该名称似乎解析为skynet-codebuild，因此，基于此，您的PipelineName是skynet。在您的策略中，您正在为资源arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}提供访问logs:CreateLogGroup。从您的错误中我可以gle gleen应该是 arn:aws:logs:ap-southeast-1:598xxx:log-group:/aws/codebuild/skynet:log-stream:...，但实际上是 arn:aws:logs:ap-southeast-1:598xxx:log-group:/aws/codebuild/skynet-lambda:log-stream:...

您的CodeBuild项目实际上可能称为${PipelineName}-lambda？您可能更容易解决这个问题的一种方法是在政策中使用语句：

- Effect: Allow
  Resource:
  - !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}-*'
  - !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}-*/*'
  Action:
  - 'logs:CreateLogGroup'
  - 'logs:CreateLogStream'

应该允许您的CodeBuild创建loggroups和logstreams，其中代码构造以PipelineName-的名称开头。

更新：感谢您的完整云形式模板。不出所料，您的代码建筑项目命名为${PipelineName}-lambda，这就是为什么您的策略不匹配的原因。如果您要仅为该项目创建日志，则需要以以下方式替换您的语句：

- Effect: Allow
  Resource:
  - !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}-lambda'
  - !Sub 'arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}-lambda/*'
  Action:
  - 'logs:CreateLogGroup'
  - 'logs:CreateLogStream'
