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

Hi !

 I'm running docker universe jobs and found the following issue:

  • created a docker image with 100 "pool user" condoruser001, condoruser002,.... They have their home directories and etc created inside the docker image.
  • all the separate condor job is mapped to slot users on the execute hosts condoruser001, condoruser002, etc...
  • 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
  • How can I fix this ? I want that the jobs are seeing the docker image's home directories,

Thanks in advance, for any help, some conf and log below,


Relevant settings on the master side:


DOCKER_VOLUMES = scratch, data, y, s, r, p, z
DOCKER_MOUNT_VOLUMES = scratch, data, y, s, r, p, z

ps -aux output on the execute host:
