[HTCondor-users] Executable file not found error for docker universe job

[Zhuo Zhang <zhuo.zhang@xxxxxxxx>]

Hi,

I have a simple docker image fm, and it can run successful when 
launching the image container locally. But when I use docker universe 
and send the image fm to HTCondor, the job is in Hold status. And the 
hold reason is "Error running docker job: [8] System error: exec: 
'run_fm.pl': executable file not found in $PATH".

The perl script run_fm.pl can be run inside docker container 
successfully when launching container on the host, but why it cannot be 
found when sending the image to condor?

FYI, my Dockerfile is:

        ----------------------------------

        FROM centos:latest
        LABEL maintainer="xxx"
        RUN mkdir -p /home/user/working_dir
        COPY xxx...
        ENV PATH 
".:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
        ENV LD_LIBRARY_PATH 
"/usr/lib64:/usr/lib:/usr/local/lib:/usr/local/lib64"
        WORKDIR /home/user/working_dir
        RUN ...

                ...

        ENTRYPOINT ["run_fm.pl"]
        CMD ["/home/user/working_dir", "test.cfg", "test.log"]
