CKA 模拟真题 Killer.sh | Question 3 | Scale down StatefulSet
Use context: kubectl config use-context k8s-c1-H
There are two Pods named o3db-** in Namespace project-c13. C13 management asked you to scale the Pods down to one replica to save resources.
译文
名称空间 project-c13 中有两个名为 o3db-** 的Pod。C13管理层要求你将Pods缩减到一个副本，以节省资源。
解答
检查pods
k -n project-c13 get pod | grep o3db |
检查常用资源
k -n project-c13 get deploy,ds,sts | grep o3db |
查看pod标签,可以看到statefulset字段
k -n project-c13 get pod --show-labels | grep o3db |
对statefulset中3db进行缩容
k -n project-c13 scale sts o3db --replicas 1 |
