kubernetes没有为ingress-nginx控制器创建ELB

Question

我正在尝试使用此指南配置类型为LoadBalancer的 ingress-nginx-controller。
我正在观察的几个问题 -
问题＃1）它不会在AWS上创建和部署ELB。
问题＃2） 外部IP状态显示为待定状态。

$ kubectl get services -n ingress-nginx  
NAME            TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE   
ingress-nginx   LoadBalancer   10.108.245.210   <pending>     80:30742/TCP,443:31028/TCP   41m  

我跟着那里提到的每一步

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml  
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/service-l4.yaml  
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/patch-configmap-l4.yaml  

这是来自豆荚的日志 -

上述错误表明服务未正常运行。 在描述服务输出中也没有出现任何事件 -

我知道有一个服务规范标签externalIPs，但这里的期望是，一旦创建了ELB实例，它将自动填充 -

spec:
  type: LoadBalancer
  externalIPs:
  - {{ ingress_lb_address or vip or masterIP }}

如果我在这里缺少任何东西，请告诉我。

Answer 1

找到了根源。 群集中的所有资源都缺少云提供程序标记。

~$ kubectl cluster-info dump | grep LoadBalancer  
 E1228 14:35:47.072444 1 core.go:76] Failed to start service controller: WARNING: no cloud provider provided, services of type LoadBalancer will fail

Answer 2

aws ALB，CLB，ELB都需要花费一些时间来配置最长5-10分钟的时间。

即使你看看链接： https ： //aws.amazon.com/blogs/opensource/kubernetes-ingress-aws-alb-ingress-controller/

这是ALB的入口控制器
