kubectl get service 不顯示服務狀態

現象：

[root@k8s-master01 kubernetes]# kubectl get service
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   18d

解決辦法：

申明端口

kubectl expose deployment nginx --port=80 --type=LoadBalancer

查看結果：

[root@k8s-master01 kubernetes]# kubectl get service
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   18d
[root@k8s-master01 kubernetes]# kubectl expose deployment nginx --port=80 --type=LoadBalancer
