I'm using the Blueocean and Pipelines on Alpine linux and started seeing next error on each Pipeline SH step:
[Pipeline] sh[decline_cookies_policy-testing-job] Running shell script
ps: unrecognized option: p
BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.
Usage: ps [-o COL1,COL2=HEADER]
Show list of processes
-o COL1,COL2=HEADER Select columns for display
+ echo hello world[Pipeline] }
Looks like plugin tries to call `ps` with unsuported for Alpine parameters on each sh step.
