amazon-web-services - EKS : could not find any suitable subnets for creating the ELB

Question

我正在尝试使用 loadBalancer 向外界公开服务类型服务。

为此，我关注了这个文档

https://aws.amazon.com/premiumsupport/knowledge-center/eks-kubernetes-services-cluster/

我的 loadbalancer.yaml看起来像这样

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  type: LoadBalancer
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80

但是负载均衡器没有按预期创建我收到以下错误

Warning  SyncLoadBalancerFailed  8s (x3 over 23s)  service-controller  Error syncing load balancer: failed to ensure load balancer: could not find any suitable subnets for creating the ELB

似乎是因为子网标签中的一些问题要解决，但我的子网中有所需的标签

kubernetes.io/cluster/<cluster-name>. owned  
kubernetes.io/role/elb   1

但是，我仍然收到错误 could not find any suitable subnets for creating the ELB

默认情况下，AWS EKS 仅将负载均衡器附加到公有子网。为了在私有(private)子网中启动它，您不仅需要标记您的子网(看起来就像您所做的那样)，还需要注释您的负载均衡器-

service.beta.kubernetes.io/aws-load-balancer-internal: "true"
