CRIU @Plumbers

CRIU @Plumbers

[Pavel Emelyanov]

Hi,

There's a call for micro-conferences now open at the upcoming Plumbers
conference [1]. Before this one, CRIU was typically included into the 
containers MC [2], but this year we can try to organize a separate [3]
track if there's enough topics and attendees.

Suggestions and thoughts are welcome.

Thanks,
Pavel

I think it might be worthwhile - my main concern is that it not conflict
timewise with the containers summit.

I'm very interested, hopefully I can (I should) get back some time to
work on CRIU to have something to present.

Given the wide spectrum of CRIU use cases, I am also in favor of organizing
a separate track for it.

To that end, I can present and do a live demo of how CRIU was used to
provide native Docker container checkpoint and restore.  This can be a full
presentation by itself or combined with another presentation.

A minor nit: for consistency, can we call it checkpoint/restore instead of
checkpoint/restart?

You mean ContainerCon?  That's running concurrently with LinuxCon, so it
shouldn't conflict with either of the two plumbers days.

That's great :) I'll start filling the page with data soon then. Feel free to
join and add the stuff you want.

Google gives ~600k results for "checkpoint/restart" vs ~900k for "checkpoint/restore"
so I don't mind :)

Sorry didn't mean "summit".  I just mean the containers track at plumbers.

Yes, Plumbers can take care of the scheduling.  Since we have a Seattle
local team, we'll help running containers, which should make sure
there's no overlap ...

I prefer "restore" (perhaps a more migration focused term) myself, but I think
there is some history behind "restart" (perhaps a more fault tolerance focused
term) from at least the Berkeley Lab's Checkpoint/Restart project, which has
software releases from 2005 and papers from 2002.

Since everyone is in agreement, let's call it checkpoint/restore then.
Restart often implies stop + start and, in fact, Docker already has a
restart command which does exactly that.
