Stress-ng: Using pubma sys_admin stress-ng command fails on EKS cluster

[uditgaurav]

Details

• I'm running stress-ng using Pumba on the EKS cluster. After the chaos completion, the Pumba pod gets into the Failed state, and the Pumba pod log gives the following error:

time="2020-10-20T11:43:21Z" level=debug msg="stop stress containers after duration" duration=2m0s

@uditgaurav I can reproduce this error. It seems you cannot run stress on K8s now. It will take me some time to inspect the failure and fix this issue. Thank you for reporting it!

@alexei-led the issue occurred because of cgroup, the dockhack is too old , you must change it , I had already fixed the issue
