Litmus chaos实验状态失败步骤:在chaos注入阶段失败

Question

我正在我的pod上运行一个cpu-hog实验，并看到它的失败步骤:在混沌注入阶段失败。没有看到任何关于它失败的原因的日志。感谢任何人的帮助。实验、服务帐户和结果文件似乎创建得很好，然而，判决显示它失败了。当工作(跑步者)正在进行时，我抓不到木头。

参考：Cpu-hog experiment yamls I am using are here

k logs litmus-8548bd-skvbt -n litmus

Kill container命令对于我所拥有的分发包不能正常工作。下面的命令对我很有效。更新了引擎yaml中的环境变量

- name: CHAOS_KILL_COMMAND
  value: "kill $(find /proc -name exe -lname '*/md5sum' 2>&1 | grep -v 'Permission denied' | awk -F/ '{print $(NF-1)}' |  head -n 1)"
