CodeBuild无法创建日志

我通过CloudFormation生成的CodeBuild服务具有以下角色

  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'

出了什么问题 
- !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？

答案 0 :(得分：2)

看来，您提供角色的价值与其预期的价值之间可能略有差异。

您似乎正在使用基于${PipelineName}-codebuild的名称创建一个角色，该角色似乎已解析为skynet-codebuild，因此基于此，PipelineName为{{ 1}}。在您的政策中，您可以为资源skynet授予logs:CreateLogGroup的访问权限。我可以从你的错误中得到arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}，但实际上是arn:aws:logs:ap-southeast-1:598xxx:log-group:/aws/codebuild/skynet:log-stream:...

您的CodeBuild项目是否可能实际上被称为arn:aws:logs:ap-southeast-1:598xxx:log-group:/aws/codebuild/skynet-lambda:log-stream:...？您可以更轻松地解决这个问题的一种方法是在您的政策中使用以下语句：

${PipelineName}-lambda

应允许CodeBuild创建LogGroups和LogStreams，其中CodeBuild以- 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' 的名称开头。

更新：感谢您使用完整的CloudFormation模板。正如预期的那样，您的CodeBuild项目名为PipelineName-，这就是您的策略不匹配的原因。如果要授权仅为该项目创建日志，则需要使用以下内容替换语句：

${PipelineName}-lambda
