Kubemark压测常用命令

1、查看pod信息

kubectl describe po hollow-node-1693 -n kubemark

2、描述节点信息

kubectl describe no izuf6clt44axl097nfxyoaz

3、分析节点日志

kubectl logs hollow-node-999 -n kubemark -c hollow-kubelet

4、查看kubemark资源信息

kubectl get sts -n kubemark -o yaml

5、搜索不是Running状态的pod

kubectl get po -n kubemark | grep -v Running

6、给hollow-node扩缩容

kubectl scale sts hollow-node --replicas=3000 -n kubemark

replicas表示hollow-node的数量

7、实时查看kubemark的拉起hollow-node进度

kubectl get po -n kubemark -w

8、批量操作资源（如pod、node），demo的是删除节点

kubectl get node | grep hollow-node | awk '{print $1}' | xargs -I{} kubectl delete node {}

9、删除kubemark里的hollow-node

kubectl delete po hollow-node-3627 -n kubemark

10、查看hollow-node的yaml

kubectl get hollow-node-579 -n kubemark -o yaml 

11、删除hollow-node的pod

kubectl get po -n kubemark | grep -v Running |awk '{print $1}' | xargs -I{} kubectl delete pod {}

12、给hollow-node打标签

kubectl get node | grep hollow-node | awk '{print $1}' | xargs -I{} kubectl label node {} only-use-for-test-pod=true

13、给指定的node打标签

kubectl get no -o wide |egrep "10.197.75.79|10.197.75.80|10.197.75.81|10.197.75.82|10.197.75.83|10.197.75.84" | awk '{print $1}' | xargs -i kubectl label node {} only-use-for-kubemark-pod-2=true

14、给hollow-node打注解

kubectl get node |grep hollow-node |awk '{print $1}' | xargs -I{} kubectl annotate node {} alibabacloud.com/node-colocation-config='{"beoverquotamem":1,"reservationcpu":0.3,"enableColocation":true,"beoverquotacpu":1,"ioPressureUtil":1,"reservationmem":0.3,"networkOutboundPressure":0,"networkInboundPressure":0}'

15、去除标签

demo是去除了所有节点的标签：not-hollow-node=

kubectl get node | awk '{print $1}' | xargs -I{} kubectl label nodes {} not-hollow-node-
