Re: [HTCondor-users] Docker in Condor



@Todd: Looking forward to the Docker universe!Â

@Joan: ÂLike the design doc for the Docker universe says, using Docker is much like using the VM universe which is the same in that regard. A key point of Docker is to get OS isolation and rather than shared OS environments. I'm anticipating personal cloud computing where elastic compute resources are can be used without needing a manually administered grid environment. One of the elements of such systems is using Âcryptographic keys for trust rather than "superuser" things like uids.

@Tiago: ÂYes, I know there are knobs for twiddling those things but I need to focus more on the applications and would like to collaborate with others who work on that side of things.

Thanks,

Jim

Awesome Todd. That is exactly the info I was looking for. I'll poke around that design doc and plan on being your first guinea pig (as opposed to rolling our own). I can wait until first quarter 2015.

Hi All,

Quick question. Has anyone experimented with using Docker as a job
container internal to Condor? We are experimenting with it to improve
how we manage the job environment for Condor jobs. Just curious if
anyone was doing anything already. General searches (as well as here)
didn't point me to any examples.

Thanks!

Here at the UW CHTC, some HTCondor developers have also done a bunch of experimenting w/ Docker, had discussions with Docker folks at OSCON 2014 re Docker+HTCondor, etc. Be aware that we are planning to add first-class support for HTCondor management of Docker containers as jobs in the first quarter of 2015. I.e. a "universe = docker" option in the submit file. The ticket for this is at
 https://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=4497
which at this point just includes a link to a design document that gives a high-level description of what we plan to do for the first pass. Feel free to read the design doc (it is only a couple pages) and please leave remarks in the ticket with feedback/thoughts/findings! To leave remarks in the ticket, you'll need a login on the htcondor-wiki which you can obtain by dropping an email to htcondor-admin@xxxxxxxxxxx.

regards,
Todd
