我正在尝试创建一个 EKS 集群，但没有提供主角色让 CDK 为我创建它，但它只附加AmazonEKSWorkerNodePolicy并且我收到以下错误
The provided role doesn't have the Amazon EKS Managed Policies associated with it. Please ensure the following policies [arn:aws:iam::aws:policy/AmazonEKSWorkerNodePolicy, arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly]
问题是错误是属于cdk8s还是我必须自己创建master角色？
