[HTCondor-users] basic condor sched setup for CondorCE submissions

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi again for another CE question ;)

I am now trying to setup a simple submit hosts for functionality tests
towards a CondorCE.
Since no further functionality is necessary, I aim for a simple setup,
that could be run in a small VM or as container.

The OSG documentation on remote submits to a CondorCE [1] suggest to
install the condor package for a basic sched. Since the packages from
the generic stable/dev repos do not come with a schedd repo, I tried to
define a basal config with just a master and sched daemon running. But
condor_ce_submit failed still trying to connect to the local schedd?

Next I extracted from the OSG condor flavour [2] the basic configs,
where [COLLECTOR, MASTER, NEGOTIATOR, SCHEDD, STARTD] are set up.

Unfortunately, condor_ce_submit/the wrapped condor_submit still fails
with [3] for a submit description like [4]. As far as I can see, a local
schedd is up and running [5], so I wonder how a a schedd setup could
look like to only submit to a remote Condor CE.

Since condor_ce_trace works in running the basic payload, I assume that
the CEs are working - "in principle" ;)

Would it be alternatively reasonable to connect directly to the
collector as condor_ce_trace does to submit a payload?

Cheers and thank,
  Thomas
