8.全局验证
验证测试
创建一个nginx的service试一下集群是否可用
[root@k8s bin]# kubectl run nginx --replicas=1 --labels="run=load-balancer-example" --image=nginx --port=80
pod "nginx" created
- k8s 1.18已经不再会创建
deployment了，取而代之的是直接创建pod
[root@k8s bin]# kubectl expose pod nginx --type=NodePort --name=example-service
service "example-service" exposed
此时pod已经跑起来了
[root@k8s bin]# kubectl get pods
NAME READY STATUS RESTARTS AGE

[root@k8s bin]# kubectl describe svc example-service
