kata-irc-bot<christophe> There is a proposal for a CRUST API https://github.com/kubernetes/enhancements/pull/2893 for runtime-assisted volume mounts. I don't see anyone from the Kata team in the discussion. I suggest we take a look.10:30
kata-irc-bot<christophe> There is an overview slide deck here https://docs.google.com/presentation/d/1NRnHPLAn5nu2PshjblQ_w-i0VMPyeN1Cv23p5UdmQoI/edit#slide=id.ge45784da5a_0_4210:31
kata-irc-bot<fidencio> @christophe, @feng.wang and @ddebroy themselves are part of the community.  Deep works directly with @eric.ernst and @samuel.ortiz, I think we're covered on that front.11:45
kata-irc-bot<fidencio> Thanks for bringing this up.11:45
kata-irc-bot<christophe> Thanks. That looks like an interesting proposal, but I'm a bit concerned about the non-filesystem cases (I don't understand yet how that would really work given the proposed APIs).14:07
kata-irc-bot<eric.ernst> This is just about storage.15:08
kata-irc-bot<eric.ernst> Currently there isn’t any communication “downward” with respect to mounts, as its handled only be kubelet and CSI — this is seeking to fix this so we can do things like direct mount, etc.15:09
kata-irc-bot<ddebroy> one quick update (from the discussions in k/k sig-node meeting yesterday) - the CRUST API will need to find a home somewhere in CRI (potentially as a new service) as runtimeclass awareness in Kubelet is not recommended from sig-node. So I will be updating the sections around CRUST in the KEP above to weave it back through CRI and runtimes.16:34
kata-irc-bot<eric.ernst> makes sense, I wonder how painful the change in CRI API will be.16:51
kata-irc-bot<eric.ernst> Deep - really appreciate your help here.16:51
kata-irc-bot<ddebroy> sure thing!17:10
