google 上的 kubernetes 无法创建负载均衡器 ip static

Question

虽然我保留了一个静态 IP，但我收到了以下警告，但没有创建负载均衡器：

> kubectl describe svc --namespace=api-1dt-dc
  FirstSeen LastSeen    Count   From            SubObjectPath   Type        Reason              Message

  48m       2m      15  {service-controller }           Warning     CreatingLoadBalancerFailed  Error creating load balancer (will retry): Failed to create load balancer for service api-1dt-dc/review-k8s-4yl6zk: requested ip 35.186.202.220 is neither static nor assigned to LB ad3c982840d0311e7b45942010a84004(api-1dt-dc/review-k8s-4yl6zk): <nil>

Answer 1

正如Thomas Parquier所说，这可能与不是区域ip有关。

以该服务为例：

apiVersion: v1
kind: Service
metadata:
  name: my-service-name
  annotations:
spec:
  selector:
    app: deployment-name
  clusterIP: 10.0.5.890
  externalTrafficPolicy: Cluster
  ports:
    - name: https
      port: 443
      protocol: TCP
      targetPort: 443
  sessionAffinity: None
  type: LoadBalancer
  loadBalancerIP: "72.229.?.?"

首先删除你的服务

kubectl delete svc my-service-name;

从您的服务中删除 loadBalancerIP 行（最后一行）并应用修复：

kubectl apply -f my-service-name.yaml

然后，等待 EXTERNAL_IP ip 地址已分配给您的服务

kubectl get svc;

在谷歌控制台中将此地址标记为静态 https://console.cloud.google.com/networking/addresses/list

最后，为你的 Service 中的 loadBalancerIP 行分配新的 ip 地址

在尝试使用 LoadBalancer 公开时遇到同样的问题。

  Normal   EnsuredLoadBalancer         2m (x2 over 1h)  service-controller  Ensured load balancer
  Warning  CreatingLoadBalancerFailed  2m (x2 over 1h)  service-controller  Error creating load balancer (will retry): not persisting update to service 'default/cb-gke-demo-ui' that has been changed since we received it: Operation cannot be fulfilled on services "cb-gke-demo-ui": the object has been modified; please apply your changes to the latest version and try again

好的，它似乎只适用于区域 IP...
