可以在rancher页面中执行k8s命令，也可以在Linux中配置好k8s的环境执行

Linux中创建k8s环境，rancher用户目录下

1、复制一份kubectl二进制文件到Linux中

2、创建目录.kube，创建配置文件config

文件内容和二进制文件都可以从下图kubeconfig点进去复制进行拷贝

kubectl run --generator=deployment/apps.v1 is DEPRECATED and will be removed in a future version. Use kubectl run --generator=run-pod/v1 or kubectl create instead.  
deployment.apps/nginx1 created

kubectl expose deployment nginx1  
查看和删除容器  
kubectl get service  
kubectl delete service nginx1

kubectl expose deployment nginx1  
对外暴露一个服务，增加type=NodePort  
kubectl expose deployment nginx --port=80 --name=ng --type=NodePort  
水平扩展，replicas的值是副本数量  
kubectl scale deployment nginx --replicas=1

kubectl describe deployment nginx

kubectl get pod

kubectl get deployment  
kubectl delete deployment nginx1-\*\*\*

升级容器  
kubectl set image deployment NAME CONTAINER\_NAME=IMAGE
