Re: [HTCondor-users] Recover the docker container exit code in the PostScript

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi Andres,

IIRC are the pre and post scripts running in their own context but not 
in the actual job context, so that the exit/return code should not be 
available.

Maybe it might work to (mis-)use a job wrapper for something like 
catching the exit codes, but tbh I would have my doubts if it works 
beyond plain vanilla jobs with Docker universe jobs...

Cheers,
  Thomas
