我的 CodeBuild 服务具有以下角色，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 不能写入日志？

服务角色 arn:aws:iam::598xxx:role/skynet-codebuild 不允许 AWS CodeBuild 为构建 arn:aws:codebuild:ap-southeast-1:598xxx:build/skynet-lambda 创建 Amazon CloudWatch Logs 日志流： 544xxx-aa88945844fa。错误消息：用户：arn:aws:sts::598xxx:assumed-role/skynet-codebuild/AWSCodeBuild-544xxx-aa88945844fa 无权执行：logs:CreateLogStream on resource:arn:aws:logs:ap-southeast-1 :598xxx:log-group:/aws/codebuild/skynet-lambda:log-stream:544xxx-aa88945844fa。服务角色 arn:aws:iam::598xxx:role/skynet-codebuild 不允许 AWS CodeBuild 为构建 arn:aws:codebuild:ap-southeast-1:598xxx:build/skynet-lambda 创建 Amazon CloudWatch Logs 日志流： 544xxx-aa88945844fa。错误消息：用户：arn:aws:sts::598xxx:

您赋予角色的价值与其期望的价值之间似乎存在细微差别。

看来您正在创建一个名称基于 的角色，该名称${PipelineName}-codebuild似乎解析为skynet-codebuild，因此基于此，您的PipelineNameis skynet。在您的政策中，您授予logs:CreateLogGroup对资源的访问权限arn:aws:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/codebuild/${PipelineName}。从你的错误中我可以看出应该是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 项目是否可能被实际调用${PipelineName}-lambda？您可能能够更轻松地解决此问题的一种方法是在您的政策中使用如下声明：

- 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'

这应该允许您的 CodeBuild 创建 LogGroups 和 LogStreams，其中 CodeBuild 以PipelineName-.

更新：感谢完整的 CloudFormation 模板。正如预期的那样，您的 CodeBuild 项目名为${PipelineName}-lambda，这就是您的策略不匹配的原因。如果您只想授权为该项目创建日志，则需要将您的语句替换为以下内容：

- 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'
