Re: [HTCondor-users] home directory in docker universe - docker image's home directory not visible from inside condor job

[Gergely Debreczeni <gergely.debreczeni@xxxxxxxxxxxx>]

Hi Greg !

 Thanks for the answer and sorry for late reaction. I've crosschecked the issue

• with other docker images
• with other jobs
• and also checked condor / nvidia-docker default settings

but found no sign of any settings which would cause this behaviour which is still holds.... ð

Keep debugging...

Gergely

Symptom:

• when the docker image starts (job starts as condoruser001)  on the execute host the /home directory of the image is not visible, but somehow overmounted with the /home of the host machine

Hello Gergely:

This is very strange and unexpected.  The only way I can thing of this happening with the above command line is if the home directory inside the image is a symbolic link to one of the volumen mounted filesystems, like /p/somewhere, which is also happens to be home directory on the host machine.
