fargate的aws eks -kube -system Pods不安排在Fargate节点上

我在带有Fargate概况的AWS EKS中有一个Kubernetes群集。当我尝试在Kube-System名称空间中运行AWS负载平衡器控制器或Metrics Server时，POD并未在Fargate节点上安排，而是由默认的SCHEDULER选择。但是我尝试通过Fargate-Scheduler选择的默认名称空间部署它们，正在将其部署在Fargate节点上。

这是我用于Kube-System Fargate配置文件的CF模板：

EKSFargateProfileKubeSystem:
    Type: 'AWS::EKS::FargateProfile'
    DependsOn:
      - EKSCluster
      - EKSIAMFargateRole
    Properties:
      FargateProfileName: kube-system
      ClusterName: !Sub 'my-cluster-${Stage}'
      PodExecutionRoleArn:
        "Fn::GetAtt": [ "EKSIAMFargateRole", "Arn" ]
      Subnets:
        - !Ref PrivateSubnet01
        - !Ref PrivateSubnet02
      Selectors:
        - Namespace: kube-system
          Labels:
            - Key: k8s-app
              Value: kube-dns

请建议我是否缺少任何东西，以及为什么Kube-System的Fargate个人资料不起作用。

I have a kubernetes cluster in aws eks with fargate profiles. When I'm trying to run aws load balancer controller or the metrics server in the kube-system namespace, the pods are not getting scheduled on the fargate nodes and are picked by the default-scheduler. But I try to deploy them on the default namespace they are picked by the fargate-scheduler are are getting deployed on the fargate nodes.

Here is my CF template for kube-system fargate profile:

EKSFargateProfileKubeSystem:
    Type: 'AWS::EKS::FargateProfile'
    DependsOn:
      - EKSCluster
      - EKSIAMFargateRole
    Properties:
      FargateProfileName: kube-system
      ClusterName: !Sub 'my-cluster-${Stage}'
      PodExecutionRoleArn:
        "Fn::GetAtt": [ "EKSIAMFargateRole", "Arn" ]
      Subnets:
        - !Ref PrivateSubnet01
        - !Ref PrivateSubnet02
      Selectors:
        - Namespace: kube-system
          Labels:
            - Key: k8s-app
              Value: kube-dns

Please suggest If I'm missing anything and why the fargate profile for kube-system is not working.

...
Selectors:
- Namespace: kube-system
  Labels:  # <-- here
  - Key: k8s-app
    Value: kube-dns

您有标签设置，这意味着仅带有标签（K8S-APP：KUBE-DNS）的POD将在Fargate上运行。删除标签要求，并且群集中的所有POD kube-system名称空间将在Fargate上运行。

Selectors:
- Namespace: kube-system
  Labels:  # <-- here
  - Key: k8s-app
    Value: kube-dns

You have Labels setup which means only pod with the labels (k8s-app: kube-dns)will be running on Fargate. Remove the Labels requirement and all pods in your cluster kube-system namespace will run on Fargate.
