pabelangerOh, hmm...02:21
pabelangerI _think_ if you define a role in a trusted project, say openstack-zuul-jobs, then in a child job also add a role for openstack-zuul-jobs, the child jobs version of openstack-role-jobs is from the trusted playbook, not untrusted02:22
pabelangerI don't think I've every tested that before, but would have expected the child job role path to include the untrusted version02:23
pabelangersince the child job is also untrusted02:23

rcarrillocruzfolks, in the zuul tenant file there's no way to have a pattern glob or regex for untrusted projects?13:33
rcarrillocruzlike, any new project thta needs to be put under zuul management it seems it's required to be put under the untrusted projectrs list, i wonder if there's a way to say 'all under the org' or all following blah regex13:33
pabelangerdon't believe we support regex in main.yaml today13:35
pabelangerbut agree should be pushing all projects to be untrusted when possible13:35

pabelangerokay, ignore everything I say last night about rdo-job example, I was way too tired to be working on zuul14:46
pabelangerlooking to bounce an idea of people, if anybody is up for job design. Today in tripleo, there is the legacy hardware called te-broker, it is basically a server that does node provisioning via heat stacks.  Not wanting to add heat into nodepool, I've been toying with 2 ideas: A) use the static node driver to just SSH into te-broker and run commands via ansible, this could work if maybe use semaphore. B) use14:49
pabelangeransible OS module to run heat stacks directly from executor, I think this model is more like how we are going to do k8s?14:49
pabelangerand I guess C is drop heat, and try to move things into nodepool-builder / nodepool-launcher + zuul job to provision node14:50
*** acozine1 has joined #zuul14:53
mordredpabelanger: I'd vote for C14:56
mordredB might be a bit harder because you'd have to eitherhave that bit be trusted or you'd have to whitelist the os modules - and you'dneed to make sure sdk was installed on the executor such that it could be accessible14:57
mordredhowever - we're gonna need to instlal openstacksdk in infra anyway for the logs-in-swift, so that's not super terrible14:58
mordredpabelanger: for A - you shouldn't need a semaphore, since nodepool will only hand access to the node to one job at a time14:58
mordredyou could also do an add_host with the te-broker machine - but then you WOULD need a semaphore14:58
pabelangeryah, in fact, B1?, is testing ansible and os_heat from a nodepool node. But, I'm pretty reluctant of doing that since a job would have access to a openstack tenant where heat runs.  Fear of password leak would be high to me14:59
pabelangermordred: ah, right14:59
mordredpabelanger: but honestly- are the stacks being used from heat complicated? or are they just some multi-node sets of things?15:00
pabelangerI _think_ the issue for C, is need to figure out provider network bits that heat might be doing. I think there is a case where overlay network isn't going to work, due to the way they are testing ironic and virtual-bmc things15:01
mordredlike - if they were "make 4 machines, 2 neutorn networks, 5 cinder volumes and a magnum cluster" - I'd say "yup, that's heat's job" - but if it's just "I need 3 machines" ... nodepool is already good at that and multi-node base job is already good at settingup networking15:01
pabelangermordred: not sure, that is what I am looking into today15:01
mordrednod15:01
mordredso - I think that should still be possible to solve with a base job - maybe an alternate implementation of what we're doing upstream in multinode15:01
mordredbut stiching in provider networks instead or something15:01
pabelangerI've already port one heat stack with simple multinode job: https://review.rdoproject.org/r/14768/ hard parts now is hooking up to the provider network that te-broker created. Having meeting today to talk more about the network15:02

clarkbpabelanger: fwiw we totally do ironic mulitnode jobs upstream with virtual baremetal and overlays15:54
clarkbthere should really be only two problems with using overlays like we do, Low mtus and if you add enough nodes throughput will likely fall off as its all in cpu15:55
clarkbotherwise its just like any other network interface15:55
pabelangerclarkb: I'd be interested in show that, I'd be happy to do all the leg work too.15:55
clarkb(also if you look under the hood its basically what the cloud isdoing for you too)15:56
pabelangerin tripleo, there is some legacy reason for this te-broker I don't really understand, but happy to discuss more with you15:56
clarkbpabelanger: the history around that was we needed a way for jenkins to talk to baremetal test environments in 2012/2013 ish time frame and lifeless threw that idea out and it worked and people went with it15:57
clarkbthis was before ironic existed iirc15:57
pabelangeryah15:58
clarkbbut then no real hardware envs with switches were ever used anyway15:59
clarkband everything was virtual baremetal15:59

*** sshnaidm|off has joined #zuul16:38
pandamordred: reading at the eavesdrop log, one of the main challenges of replicating the OVB stack for tripleo is that one node acts as dhcp/bootp server to the other, so they would need to be in the same broadcast domain. SO it's not just creating n nodes and connecting them together16:39
clarkbmordred: does pbrx-build-container-images publish them somewhere too? (maybe that is what the pbrx prefix is for?)16:39
clarkbpanda: yes, that is what our overlay network role is for16:39
clarkbpanda: puts everything on the same l2 so that neutron can have similar behavior16:39
clarkb(actually it was nova net that really needed it, but we (openstack) do it for neutron too)16:40
clarkbmordred: why do you need libffi on alpine but not rpm/deb?16:41
clarkbmordred: I'm guessing the rpm/deb list is/was incomplete?16:41
pabelangerclarkb: panda: Is there an example today how to create the overlay network in openstack-infra? I'm struggling a little to see how it would work, if we kept using the ipxe image from https://git.ipxe.org/ipxe.git today16:43
clarkbpabelanger: its a role in zuul-jobs iirc16:43
clarkbroles/multi-node-bridge16:44
pabelangerthat would mean the ipxe node needs to suppot vxlan, is that right?16:46
clarkbpabelanger: it depends on where ipxe is running, are you nova booting a pxe image?16:47
clarkbor is this running on top of qemu/kvm on a "proper" instance?16:48
pabelangerclarkb: yah, I would imagine that nodepool would boot the ipxe image, so that in was part of the ansible inventory16:48
pabelangerthat is the general idea now16:48
clarkbgotcha so thats the disconnect you are directly managing a nova instance as if it weren't managed by nova16:48
clarkbI was assuming you were running on top of that16:49
pabelangerright, in this case, te-broker uploads the ipxe image into nodepool tenant, then runs heat to boot it, with a provider network16:49
clarkb(this is how the ironic tests work with the virtual baremetal stuff, nodepool provides "proper" instance, then we networking those together and run "baremetal" on qemu/kvm16:49
pabelangeryah, I think in the case of tripleo, they would likely need nested-virt for how much they are doing with the baremetal node16:51
pandapabelanger: the ipxeboot image is currently in the tenant we create the stack on16:52
*** myoung is now known as myoung|lunch16:52
*** myoung|lunch is now known as myoung16:53
pabelangerright, getting the ipxboot image into nodepool and update I don't think is an issue, having it attach to the vxlan is what I think is. And I think this is the main reason provider networks are used16:53
clarkbare they provider networks or dynamically created neutron networks?16:54
pabelangerlet me find code again, I might be using wrong name16:54
clarkb(it doesn't matter a whole lot, except that if they are preprovisioned hard coded provider networks then nodepool can probably hack around that and have a pool per network)16:55
pabelangerhttp://git.openstack.org/cgit/openstack-infra/tripleo-ci/tree/scripts/prepare-ovb-cloud.sh is how they tenant is bootstrapped16:55
pabelangerhttp://git.openstack.org/cgit/openstack-infra/tripleo-ci/tree/scripts/te-broker/create-env is how the nodes come online16:56
*** myoung is now known as myoung|lunch16:58
pandapabelanger: that is probably how rh1 was created, it's quite old16:58
pabelangerack16:58
pabelangercould you link the newer way for provision network being created today16:59
pabelangerclarkb: like the idea of per-pool, could be a first step. Was trying to think of a way a nodeset could express the network isolation from tenant17:00
pandapabelanger: it's a set of heat templates17:00
clarkbpabelanger: I think it would likely be very hacky, you'd have to always request a nodeset that could only fit into a single pool and you'd hvae to hardcode networks per pool17:01
clarkbnot likely to be a good long term option17:01
mordredclarkb: yeah - the rpm/deb list is incomplete - we should maybe just put the libff-dev/libffi-devel lines back how they were efore that patch17:02
openstackgerritMonty Taylor proposed openstack-infra/nodepool master: Build container images using pbrx  https://review.openstack.org/58273217:03
mordredclarkb: like that ^^17:03
pabelangerclarkb: agree, but could be a good POC to start with until we figured out how to better make the creating of networks more dynamic in nodepool17:04
clarkbmordred: do you need python3 dev on alpine too? I'm assuming that its available on the python alpine image already but not necessarily on every alpine image? also linux headres surprises me17:06
mordredclarkb: yeah - linux headers is definitely needed17:06
pandapabelanger: it's a set of heat templates combined together, from these https://github.com/cybertron/openstack-virtual-baremetal/tree/master/environments17:06
clarkbmordred: huh17:06
mordredclarkb: you do need python3-dev on alpine but not on python:alpine - installing it in python:alpine doesn't seem to explicitly hurt - but it does install headers that don't match th epython that'll be in the resulting image17:07
mordredclarkb: I think I'm currently imagining that the only likely users of the alpine profile in the zuul/nodepool bindep files is python:alpine container images17:07
clarkboh because python is building their own python on top of alpine, hrm17:08
mordredyah17:08
mordredclarkb: you know though ... I *could* put in a filter in pbrx17:08
mordredclarkb: to remove any mention of python3-dev or python-dev from the bindep list17:08
mordredsince pbrx knows what it's doing there17:08
mordredand you're right- we do technically want python3-dev in there for alpine in general17:08
clarkbthat might be a good compromise17:09
pabelangerpanda: thanks, I'll see what that would like using shade17:09
clarkbpabelanger: panda fwiw I think a big reason we haven't already added support for similar in nodepool is that many clouds don't support managed networking so we've had to deal with them in another manner anyway and quota limits on those resources when you do have access to them tend to be very low17:10
clarkbobviously if you control the cloud that is of less concern17:11
pabelangerYah, I'd be keen to solve it outside of nodepool, but think in this case, means zuul job access to tenant password to create them.17:12

pabelangerwith launch-retries for nodepool: https://zuul-ci.org/docs/nodepool/configuration.html#openstack-driver could we allow for that to be disabled, say launch-retires: -1 to have nodepool keep trying forever to bring a node online? To me, this would be kinda how nodepoolv2 works if a cloud was having issues17:36
*** myoung is now known as myoung|bbl17:39
Shrewspabelanger: that seems like a bad way to handle cloud issues. a node request could sit forever, never getting fulfilled, even if another cloud could fulfill it if it were resubmitted17:42
Shrewsbut maybe for a user of a single cloud, you'd want that? dunno17:43
pabelangerright, I'm personally okay with that, since that is how it worked before17:44
pabelangertoday, we are finding with rdo-cloud, NODE_FAILURE reported by zuul, have increased recheck commands17:44
pabelangerI guess this is the man different of launch-retries, I think old nodepool did that across all provider, nodepoolv3 will pin to single for lifetime of value17:46
pabelangerwhich, in this case, nodepool only has once cloud :(17:46

mordredpabelanger, Shrews: we definitely haven't optimized things for the single-cloud case19:24
pabelangeryah, I'd really love to say adding a 2nd cloud is the right solution, but there is a financial cost to first deal with19:25
tobiashpabelanger: I just came across a shortcoming of the hdd governor19:26
tobiashit checks the state_dir if it has enough disk space19:27
tobiashhowever we have more options than the statedir like git_dir and job_dir where the last one might be the one we want to check19:27
pabelangerAh, right. I assumed everything was in the state_dir19:28
pabelangergit_dir can be outside of that19:29
tobiash(like me ;) )19:29
pabelangertobiash: what is your directory setup?19:29
tobiashstatedir=/var/lib/zuul, git_dir=/var/cache/zuul-executor/git, job_dir=/var/cache/zuul-executor/jobs19:30
tobiashwhere I have a persistent volume mounted at /var/cache/zuul-executor19:30
pabelangeryah, I guess we'd need to some how update the sensor to check all three sizes19:31
tobiashI don't have the state_dir on that volume because I didn't want to persist the ansible modules zuul is preparing at startup (just as a precaution)19:31
tobiashprobably (and also send stats of them)19:31
pabelangeryah19:31
tobiashI came across that because I wanted to add the avail_hdd_pct to my monitoring and asked myself what this would be checking in my env19:32
pabelangeryah, in the case of rdoproject and openstack, everything is under state_dir, as seen at http://grafana.openstack.org/d/T6vSHcSik/zuul-status?orgId=119:33
pabelanger(openstack)19:33
pabelangerbut I do agree, we should maybe consider all 3 dirs19:34
pabelangerclarkb: ^ grafana percentages are nice!19:34
tobiashpabelanger: that grafana tells me that you might need more executors19:34
tobiashqueued executor jobs are wasted build nodes because the jobs queued there already have a locked fulfulled nodeset19:35
pabelangermaybe, I haven't really looked19:37
pabelangerour RAM and HDD sensors look okay19:37
pabelangermaybe loadavg19:37
tobiashprobably19:38
pabelangertobiash: okay, I now understand what you said about wasted19:42
tobiash:)19:43
pabelangeryah, would be interesting to try another executor and see what happened19:43
pabelangeryah, 20 would be the limit of load_multiplier19:45
pabelangerso agree!19:45
corvuspabelanger: well, that's a change19:45
pabelangercorvus: bump it up you mean?19:46
corvuslook further back in the history and you'll see we geverally haven't had many jobs waiting.  things seem to have changed starting a few days ago.19:46
corvuspabelanger: it may be worth considering that the hdd check is causing us to run fewer jobs19:46
pabelangeryah, I can look19:47
corvus(or maybe something else)19:47
pabelangerwe also got 100 more nodes from packet on 2018-07-1719:48
corvusbut yes, all other things being equal, queued jobs mean more executors needed19:48
corvuspabelanger: ah, that could be a contributing factor :)19:48
tobiashlooks like it started 7 weeks ago and is worse since a few days: http://grafana.openstack.org/d/T6vSHcSik/zuul-status?orgId=1&panelId=24&fullscreen&from=now-90d&to=now19:49
pabelangeralso looking to see when we switched to ansible 2.5, maybe something there too19:49
corvusi guess we probably started using the hdd governor around the same time we got more nodes.  yay multi-variables :)19:49
pabelangerI think hdd governor default to 5%, so looking at graphs, I'd expect we still have a lot of disk space19:50
corvuspabelanger: then the really recent spike is probably mostly added quota19:51
pabelangeryah, think so too19:51
pabelangerI'll move this to openstack-infra and see if we want to launch another19:52
corvustobiash: it turns out one of our "swifts" is a ceph-radosgw.  i'm writing the swift upload role to work with both that and real-swift.  looks like they both should work (with some minor tweaks, hopefully temporary).  we should both be able to use the same role.  :)19:54
tobiashcorvus: cool19:54
tobiashcorvus: will it create a bucket for every job or will this be configurable?19:55
corvustobiash: i expect it to be configurable.  each container can hold "a lot" of files, so we'd probably just shard by change id (maybe 100 containers total)19:57
tobiashI think in our case we'd need a bucket per tenant19:57
corvusshouldn't be a problem19:57
tobiashwe need to put authenticated apache's in front as a reverse proxy, hopefully that works with swift as a backend19:59
*** myoung|bbl is now known as myoung20:01
corvusthat i can't answer :)20:04
tobiashwe will just try that :)20:05
tobiashand if it works fine, if not we have to go with a file server for now20:05
tobiashbut I think it will work20:05
corvusit seems like it should20:25
Shrewsmordred: corvus: i think we should plan to merge remaining nodepool changes and restart in OS infra next week so we can keep an eye on the shade-to-sdk changes. Next week is the last week I will be around for quite a while (at least a week) so can't help after that.20:52
Shrewsa few outstanding reviews just need a second +220:52
