// 查看Events事件kubectl describe pod名称 ?// 通过deploy查看事件kubectl describe deploy/nginx //查看发布具体信息kubectl describe svc name名称//查看日志kubectl logs ?pod名称//进入容器排查kubectl exec -it pod名称 bash

//把当前nginx:1.10版本更新至1.11[root@master ~]# kubectl set image deployments/nginx nginx=nginx:1.11orkubectl edit deploy/nginx ?编辑里面的镜像版本号保存退出

// 布署资源的状态kubectl rollout status deploy/nginx// 发布的历史版本kubectl rollout history deploy/nginx

//回退到上一个退版kubectl rollout undo deploy/nginx ??默认回滚到上一个版本//查看状态kubectl ?rollout status deploy/nginx//回到指定版本kubectl rollout undo deploy/nginx --to-revision=4

// 把当前的pod扩容到5个kubectl scale deploy/nginx --replicas=5缩减也是上述命令

// 删除podkubectl delete deployment.extensions/nginx//删除servicekubectl delete service/nginx-service//查看 kubectl get allkubectl get deploy
