kata-irc-bot<david532> So good news is the virtio-fs NEMU solves my FUSE issues!06:39
kata-irc-bot<david532> The next step is to figure out how to integrate Traefik with my Kaya Containers. Has anyone done work with reverse proxying and Kata?06:40

kata-irc-bot<david532> For what it's worth, I believe I might be able to dump all of these to bridge since we can't network connect them together in a traditional sense. Then use Traefik with a key value store and update the corresponding IPs with a backend and front it that way. Just a thought if anyone else had ideas.09:13
kata-irc-bot<graham.whaley> @archana.m.shinde @manohar.r.castelino for any input on ^^ wrt Traefik, proxying etc.09:15
kata-irc-bot<david532> Might try jwilder nginx proxy as it'll be a little less upfront configuration. Just PoC'd it, so need to dive more into it again since it's been nearly 4 months.09:37

kata-irc-bot<dpopa> Hi! This is Diana from firecracker team. Your Firecracker CI pipeline is failing.20:39
kata-irc-bot<dpopa> Though I d let you know about this20:39
kata-irc-bot<eric.ernst> @manohar.r.castelino good news ^^ :S20:40
kata-irc-bot<eric.ernst> https://github.com/firecracker-microvm/firecracker/pull/105020:40
kata-irc-bot<eric.ernst> @salvador.fuentes -- I'm guessing this has to do with the issue @bergwolf introduced?20:41
kata-irc-bot<manohar.r.castelino> @eric.ernst stranange.. not reason it should fail20:41
kata-irc-bot<manohar.r.castelino> it may be our CI20:41
kata-irc-bot<eric.ernst> I think it is.20:41
kata-irc-bot<eric.ernst> @bergwolf introduced a new test.20:41
kata-irc-bot<eric.ernst> I'm *guessing* that's what this is about...20:42
kata-irc-bot<manohar.r.castelino> what test20:42
kata-irc-bot<dpopa> http://jenkins.katacontainers.io/job/kata-containers-firecracker-PR/131/20:42
kata-irc-bot<gabriela.cervantes.te> @dpopa yes this PR broke the firecracker CI (https://github.com/kata-containers/tests/pull/1839) and now @bergwolf is trying to fix that with https://github.com/kata-containers/tests/pull/184720:42
kata-irc-bot<salvador.fuentes> @eric.ernst yeah, it is20:42
kata-irc-bot<dpopa> How can one spot the test that is failing from that list?20:42
kata-irc-bot<eric.ernst> Searching through the logs (it is painful, something we're working on improving)20:43
kata-irc-bot<salvador.fuentes> should we revert the change until it is fixed by Peng?20:43
kata-irc-bot<gabriela.cervantes.te> at the logs you will find something like `13:12:02 cd integration/stability && ./hypervisor_stability_kill_test.sh 13:12:03 Starting hypervisor stability test 13:12:04 d823266db5f00905757ce1a796435bf18e14fec4224440178c5ee459fae10a56 13:12:06 ERROR: hypervisor count:0 expected:1`20:43
kata-irc-bot<gabriela.cervantes.te> @salvador.fuentes maybe we can skip the test for FC at the makefile until this gets fixed20:44
kata-irc-bot<eric.ernst> Seems reasonable to me, @gabriela.cervantes.te20:45
kata-irc-botAction: eric.ernst wonders if we can sort stderr and stdout in our logs?20:46
kata-irc-bot<eric.ernst> for tests?20:46
kata-irc-bot<eric.ernst> ie, have two options for console output.  @krsna1729 - you do this in your repo, right?20:47
kata-irc-bot<salvador.fuentes> I think we dont use stderr on our error messages20:47
kata-irc-bot<eric.ernst> ah.20:47
kata-irc-bot<salvador.fuentes> but we should xD20:47
kata-irc-bot<salvador.fuentes> yeah, lets skip the test until it is fixed20:47
kata-irc-bot<salvador.fuentes> @gabriela.cervantes.te can you help us with the change?20:48
kata-irc-bot<krsna1729> Yes we do20:49
*** pcaruana has quit IRC20:50
kata-irc-bot<eric.ernst> do we only test Firecracker w/ Docker atm @salvador.fuentes?20:53
kata-irc-bot<eric.ernst> I was checking to see if we have the devicemapper bits for containerd as part of our install today.20:53
kata-irc-bot<salvador.fuentes> @eric.ernst we only run docker, does it work with k8s and containerd?20:55
kata-irc-bot<gabriela.cervantes.te> @salvador.fuentes yes let me do that20:56
kata-irc-bot<salvador.fuentes> thanks @gabriela.cervantes.te20:56
kata-irc-bot<eric.ernst> Yes, with some extra configrurations.20:56
kata-irc-bot<eric.ernst> Let me dig up the docs...20:56
kata-irc-bot<salvador.fuentes> cool, so that we can add that to the FC CI20:57
kata-irc-bot<eric.ernst> @gmmaharaj did you have BKM for this?20:57
kata-irc-bot<eric.ernst> I'm not easily finding it in our repos/docs20:59
kata-irc-bot<gmmaharaj> @eric.ernst not today. it seems containerd has not yet relesaed their devmapper snapshotter.20:59
kata-irc-bot<gmmaharaj> their latest (1.2.7) does not have it yet. I am waiting for one to land with it after which we can switch over to test FC + containerd.21:00
kata-irc-bot<eric.ernst> ok, but i thought we had tested it before,r ight?21:00
kata-irc-bot<eric.ernst> ie, BKM shuold just be registering the plugin, etc. ?21:00
kata-irc-bot<gmmaharaj> ohh that is by running contianerd from master (build form source)21:00
kata-irc-bot<gmmaharaj> right.21:00
kata-irc-bot<eric.ernst> because there's more to it than just that -- there's also thinpool mgmt, etc?21:01
kata-irc-bot<gmmaharaj> https://github.com/clearlinux/cloud-native-setup/blob/master/clr-k8s-examples/containerd_devmapper_setup.sh#L49-L5221:01
kata-irc-bot<gmmaharaj> that bit.21:01
kata-irc-bot<gmmaharaj> https://github.com/clearlinux/cloud-native-setup/blob/master/clr-k8s-examples/containerd_devmapper_setup.sh21:01
kata-irc-bot<gmmaharaj> that file will create a loopback device, setup a device mapper thin pool on that device and then plug that info into your config.toml for containerd.21:01
kata-irc-bot<eric.ernst> great, thx21:02

kata-irc-bot<gmmaharaj> @eric.ernst you mean have that pushed to `/opt/kata` along with the other files?21:59
*** altlogbot_0 has quit IRC22:01
kata-irc-bot<eric.ernst> or something.22:01
kata-irc-bot<gmmaharaj> is there are use-case which we are trying to address.. only reason i am asking is that, in most cases we would have containerd installed on the host prior to installing kata using kata-deploy. In the case of docker, docker-ce pulls containerd as a dependency.. for k8s that would be a runtime handler that folks would have installed prior to calling kubeadm.22:03
kata-irc-bot<eric.ernst> i'm trying to make it easy to use firecracker+containerd.22:04
kata-irc-bot<eric.ernst> i don't think that'll happen via containerd itself for another month or two22:04
kata-irc-bot<gmmaharaj> aaah.. gotcha.22:04
kata-irc-bot<gmmaharaj> yeah, we really need the device mapper plugin to land.22:05
kata-irc-bot<gmmaharaj> or we can use the lvm snapshotter as an out-of-tree entity while we wait for devmapper.22:05
kata-irc-bot<gmmaharaj> it is updated to match v1.2.7 release.22:05
kata-irc-bot<eric.ernst> in tree probably makes more sense for now?22:07
kata-irc-bot<gmmaharaj> in-tree is always better than out of tree22:07
kata-irc-bot<eric.ernst> either way -- built from source I stilll see FC pods failing to come up22:07
kata-irc-bot<gmmaharaj> does kata work with it?22:10
kata-irc-bot<eric.ernst> switching to latest .. testing it now22:13
kata-irc-bot<gmmaharaj> same here. let me get my machine setup22:15
kata-irc-bot<eric.ernst> i'm not seeing it work22:18
*** altlogbot_0 has joined #kata-dev22:21
*** altlogbot_0 has quit IRC22:27
kata-irc-bot<eric.ernst> Failure seems to be path assumption22:30
kata-irc-bot<eric.ernst> We see rootfs @ `/run/kata-containers/shared/sandboxes` whereas containerd expects `/run/kata-containers/shared/containers`22:30
kata-irc-bot<eric.ernst> this familiar at alL?22:31
kata-irc-bot<gmmaharaj> no.. did not see this when was fiddling with it.22:31
kata-irc-bot<eric.ernst> this only happens w/ FC, not with QEMU22:33
kata-irc-bot<eric.ernst> everything else same.22:33
kata-irc-bot<gmmaharaj> ok..22:33
kata-irc-bot<gmmaharaj> qemu works on my end.22:33
kata-irc-bot<gmmaharaj> testing fc now.22:34
