Thanks Dima.

I don't control the HTCondor insstallation, I can just use it.

At this point I am looking at running everything natively, out of Docker.

Docker was the best solution, as otherwise I have to find/install all of the other software to be installed without root privilege such as ghostscript and Xmgrace for example. So a container would have been a better solution.

I was wondering about singularity, but I am not sure how to submit a job that way.

I did find a docker image that has singularity within it...

I don't think that there is a Singularity Universe to simply give a converted .sif image to run.

Any pointer on how to run a Docker file on Singularity... Can it run it un the Docker Universe using a Singularity container since Singularity is not installed.

Hopefully someone on condor team has something better to offer; I always
subscribed to "life's too short to enable selinux" view and had "set
`selinux=disabled`" as step #2 in our new system setup checklist.

I don't know how condor deals with singularity bind mounts, vanilla
singularity container will by default mount /tmp which _may_ have a less
restrictive selinux context host-side. I.e. you could try running in
singularity, rather than docker, container and see if that works.
