Re: [HTCondor-users] Is it possible to set which classads are passed as env vars to docker?

For an 8.8 solution, you could write a wrapper script and point the "DOCKER" config value to it. The script would then be able to mangle the argument list in any way it liked. That's the approach I took with Singularity before the extra-args option was added.

Hi Jose,

for Singularity, I know that the extra arguments ad allows to tweak Singularity arguments [1]
   SINGULARITY_EXTRA_ARGUMENTS = ...

Release 8.9.1 seems to have added the same option for Docker
   DOCKER_EXTRA_ARGUMENTS = ...
but I have not tried it myself - so YMMV ;)

Cheers,
   Thomas
