All those runs should return a NonZeroExit status.
What happened (please include outputs or screenshots):
I'm trying to implement this code sample: https://github.com/kubernetes-client/python/blob/master/examples/pod_exec.py#L69-L82
But running multiple times the same command returns different results.
What you expected to happen:
I'm expecting all command execution to return the same result
How to reproduce it (as minimally and precisely as possible):
Create a test.py
Run it multiple times:
All those runs should return a NonZeroExit status.
