使用以下命令进行监控更新

# kubectl  rollout status deployment myapp-deploy
Waiting for deployment "myapp-deploy" rollout to finish: 1 out of 5 new replicas have been updated...

若发现没有问题后继续更新

# kubectl rollout resume deployment myapp-deploy
deployment.extensions/myapp-deploy resumed
# kubectl  rollout status deployment myapp-deploy

若更新时发现问题，我们可以执行回滚

查看可以回滚的版本

# kubectl rollout history deployment myapp-deploy
deployment.extensions/myapp-deploy
REVISION  CHANGE-CAUSE
1         <none>
2         <none>
3         <none>
# kubectl  rollout undo deployment myapp-deploy --to-revision=1
deployment.extensions/myapp-deploy rolled back
# kubectl rollout history deployment myapp-deploy
deployment.extensions/myapp-deploy
REVISION  CHANGE-CAUSE
2         <none>
3         <none>
4         <none>

这时第一版已经回滚成第一版了

DaemonSet 在整个集群的每个节点上只运行指定Pod的一个副本，用于系统级的管理功能
比如filebeat，收集日志的服务

现在可以尝试访问

查看访问apiVersion

这时再访问
