无法将k8s注入节点CPU故障

问题描述

[root@kube-master-192-168-131-12 ~/chaosblade-0.4.0]$ ./blade create k8s node-cpu fullload --names kube-node-192-168-131-16 --cpu-percent 80 --kubeconfig ~/.kube/config {"code":504,"success":false,"error":"unexpected status, the real value is Error","result":{"uid":"f0456b2b579c6b86","success":false,"error":"unexpected status, the real value is Error","statuses":[{"uid":"3c0911e7-32a9-11ea-a5c8-5254001fcd2f","name":"kube-node-192-168-131-16","state":"Error","kind":"node","error":"nothing returned","success":false,"nodeName":"kube-node-192-168-131-16"}]}}

但是可以使用k8s进行delete pod

[root@kube-master-192-168-131-12 ~/chaosblade-0.4.0]$ ./blade create k8s pod-pod delete --names logging-filebeat-filebeat-v1-0-m527d --namespace kube-system --evict-count 2 --kubeconfig ~/.kube/config {"code":200,"success":true,"result":"6db9b83e0f82d788"}

也可以使用blade进行node cpu 进行故障注入

[root@kube-master-192-168-131-12 ~/chaosblade-0.4.0]$ ./blade create cpu load {"code":200,"success":true,"result":"45474c0669240cb7"}
