嗨，在centos中使用kubeadm安装Kubernetes当我在yaml文件中使用负载均衡器类型创建部署时，外部IPPending用于Kubernetes LB，它停留在Pending状态

NAME         TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP      10.96.0.1       <none>        443/TCP        13m

Answer 1

请尝试运行：

kubectl describe svc <service-name>

并检查错误/警告。

下面的示例输出中的事件字段描述了可能错误的示例 - ( SyncLoadBalancerFailed - 找不到任何合适的子网来创建 ELB )：
