ps: unrecognized option: p

[herzcthu]

I'm using activemq alpine linux image rmohr/activemq:5.15.6-alpine
I see ps: unrecognized option: p on startup
I find out that alpine ps is from busybox and it is not included -p switch for ps.
activemq startup script is using ps -p to see JAVA process
adding procps in image might solve that

apk --no-cache add procps
