Re: [HTCondor-users] Trying to setup HTCondor Docker universe

[Tim Theisen <tim@xxxxxxxxxxx>]

Hello Fabrice,

In order for HTCondor to run Docker jobs, the condor has to be in the docker group. Please check your /etc/group file.

Hello,

I am attempting to setup a bunch of Ubuntu 20 machines so they can run jobs on the Docker universe. Those machine are currently used with the Vanilla universe.

I am following instructions from https://htcondor.readthedocs.io/en/latest/admin-manual/setting-up-vm-docker-universes.html#the-docker-universe, and so far Iâve only tried deployment on a single machine.

Iâve installed Docker following instructions from https://docs.docker.com/engine/install/ubuntu/ and verified root could run the hello-world demo container.

Iâve also verified that dockerd is up and running.

However upon restarting the condor daemon and inspecting the ClassAd attributes for this trial machine, it appears that there is no HasDocker attribute defined.

Is there any additional extra step that needs to be done for this to work as described in the documentation?

Condor on this machine and most of our flock execution nodes is version 8.6.8.

 

Thanks for your help.
