Re: [HTCondor-devel] Linux containerization

[Erik Paulson <epaulson@xxxxxxxxxxxx>]

C'mon, that's not what he's saying. As HTCondor is going to keep supporting Windows for a while, there will have to be a working solution for running Windows jobs. As happy as I'm sure it'd make Redhat, they're not suggesting forget about Windows.

There are two things to consider:

1. The starter have been factored to be more of a stand-alone tool, and been used as a tool in other systems like Mesos and OpenStack. HTCondor went down this path a bit many years ago with the GridShell, but that work didn't continue. Miron was ahead of his time there, and it's too bad because Condor could have been well positioned when the rest of the world realized what they needed.  

2. What I think is the bigger issue - if Docker containers become important, Condor should support them. Maybe it wraps docker, maybe the starter natively supports decoding docker images and booting them ( see https://index.docker.io/ for example containers). 

Maybe someday Condor jobs automatically get wrapped into docker containers and much of the Linux starter gets deleted and simply uses Docker. The HTCondor philosophy is not to chase the shiny technology of the day, so this isn't a likely development path anytime soon, but I'd be careful to not make decisions that would rule it out.

Oh, so you're saying they also intend to add native, complete support
