I have the following Role for my CodeBuild service, generated via CloudFormation
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:

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:GetObjectVersion'
- 's3:PutObject'
- Effect: Allow
Resource:
- !GetAtt [PipelineArtifactStore, Arn]
Action:

Whats wrong with
- !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}/*'
Why can't CodeBuild write logs?
Service role arn:aws:iam::598xxx:role/skynet-codebuild does not allow AWS CodeBuild to create Amazon CloudWatch Logs log streams for build arn:aws:codebuild:ap-southeast-1:598xxx:build/skynet-lambda:544xxx-aa88945844fa.
