Ensure 'RUN' shell command has pipefail flag
The pipefail flag -o causes the pipeline to return the exit status of the last (rightmost) command to exit with a non-zero status. It returns zero if all commands in the pipeline exit successfully. Because this option is disabled by default, you should set it to make sure the commands will failed if some problem in the pipe.
