Re: [HTCondor-users] Checkpointing in docker universe?

["Bockelman, Brian" <BBockelman@xxxxxxxxxxxxx>]

Hi Brian,

Unfortunately, I donât think that is possible in HTCondor right now.  Would be a really cool feature!  Might even be doable with a very slight twist of the Docker universe.

One tricky piece that things like CRIU can struggle with is âwhere can the checkpoint resume?â.  A different host with a different kernel or processor can really cause issues.  That is solvable, of course - but will be one of the speed bumps along the way.

Docker has had checkpointing as an experimental feature for some time now (but still only experimental) and others have been using tools like CRIU to do checkpointing of docker for longer than that.
