kubectl expose --type = LoadBalancer无效

Question

在发布以下json对象(排除变量)后,我遇到了一些外部ip地址的问题:

$json= '{
          "kind": "Service",
          "apiVersion": "v1",
          "metadata": {
            "name": ""
          },
          "spec": {
            "ports": [{
              "port": 80,
              "targetPort": 80
            }],
            "selector": {
              "app": ""
            },
            "type": "LoadBalancer"
          }
}';

该服务已创建,但没有给出外部IP.

由于无法确定问题所在,我继续使用文档(V1 kubernetes/examples/simple-nginx.md)中提供的以下命令安装kubernetes(以及定义为要安装的集群)的干净副本:

curl -sS https://get.k8s.io | bash

这当然会自动设置.然后我运行以下命令来测试LoadBalancer函数是否正常工作:

kubectl run my-nginx --image=nginx --replicas=2 --port=80

跑完后kubectl get pods确认他们已经准备好了,我暴露了这项服务:

kubectl expose rc my-nginx --port=80 --type=LoadBalancer

然后我跑kubectl get service了几分钟,没有提供公共IP ..

那不对吗？

kubectl get services

运行后(感谢GameScripting):

kubectl describe service my-nginx

我看到以下错误:

手动删除“网络->负载平衡->网络负载平衡”下的转发规则（或者您可以使用gcloud compute forwarding-rules delete）后，我能够再次获得公共IP。不知何故，转发规则似乎没有被删除并达到了限制。奇怪的是，当我运行时，Kubectl stop service它为我删除了转发规则。
