负载均衡器IP状态在kubernetes中处于挂起状态

Question

我已经使用两个Azure Ubuntu VM创建了Kubernetes群集。我能够使用Nodeport服务类型部署和访问Pod和部署。我还检查了Kube-system名称空间中pod的状态。窗格的所有状态均显示为running。但是，每当我向Loadbalancer提及服务类型时，它都没有创建LoadBalancer IP，并且其状态始终显示为pending。在初始化Kubernetes主机时，我正在使用以下命令。

kubeadm init

下面是部署和svc清单文件。

apiVersion: apps/v1 
 kind: Deployment
 metadata:
   name: nginx
 spec:
   selector:
     matchLabels:
       app: nginx
   replicas: 3 
   template: 
     metadata:
       labels:
         app: nginx
     spec:
       containers:
       - name: nginx
         image: nginx
         ports:
         - containerPort: 80

apiVersion: v1
 kind: Service
 metadata:
   name: nginx
   labels:
     app: nginx
   annotations:
     service.beta.kubernetes.io/aws-load-balancer-type: "nlb"
 spec:
   ports:
   - name: http
     port: 80
     protocol: TCP
     targetPort: 80
   selector:
     app: nginx
   type: LoadBalancer

kubectl describe svc nginx

Name:                     nginx

                          service.beta.kubernetes.io/aws-load-balancer-type: nlb

 External Traffic Policy:  Cluster

在初始化kubeadm初始化时，我们是否需要提及VM的任何IP范围（私有或公共）？要么我们是否需要更改Azure Ubuntu VM中的任何网络设置？
