Litmus chaos Experiment Status Fail Step: failed in chaos injection phase

Question

I am running a cpu-hog experiment on my pod and seeing that its failing Fail Step: failed in chaos injection phase. not seeing any logs as to why its failing. appreciate any help. The experiment, service account and results files seem to have been created fine, however, the verdict is showing that it has failed. i couldn't catch the logs when the job (runner) was underway.

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

Answer 1

Kill container command wasn't working correctly for the distrubution I have. Following command worked for me. Updated the env variable in the engine yaml

- 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)"
