Qimingelynn, will do02:15
stevebakerelynn: done02:16
elynnthanks Qiming :) This issue blocking internal fvt.02:16
elynnthanks stevebaker02:16
elynnIf I want this patch backport to kilo, I need to push it for branch proposal/kilo?02:17
stevebakerQiming: is there a Senlin talk in the main summit schedule?02:19
Qimingstevebaker, sadly, no, the talk proposal was not accepted02:20
*** achanda has joined #heat02:21
stevebakerQiming: in that case I wonder if some (all) of a design summit slot should be devoted to it?02:21
Qimingyes, that would be cool02:21
QimingI have no idea how to apply for one02:22
stevebakerQiming: propose it here, and the PTL will consult & decide https://etherpad.openstack.org/p/liberty-heat-sessions02:23
Qimingokay02:24
stevebakerwhich might be me, but I have no idea when nominations close ;)02:24
Qimingno doubts from me, ;)02:24
Qiminglooks like the etherpad is experiencing some problem02:26
elynnTry firefox02:26
Qimingelynn, the same error02:26
QimingAn error occured while loading the pad02:27

Qimingcleaning cache now02:27
*** dims_ has quit IRC02:28
Qimingnow it works02:28
elynnok, maybe I need to clean my chrome cache.02:31
Qimingstevebaker, just added one into the pad02:31
elynnstevebaker, Qiming , need to approve again for proposed/kilo https://review.openstack.org/#/c/173152/02:31
stevebakerQiming: OK, I'm thinking maybe one fishbowl session to cover all the autoscaling things, with dedicated time for senlin02:32

ramishrastevebaker: Hi, have a minute?04:03
stevebakerramishra: sure04:04
*** sdake has quit IRC04:04
ramishrastevebaker: reg https://review.openstack.org/#/c/164572/, there seems to be conflict for 'requests' dependency for os-collect-config(yum) and docker-compose(pip)04:05
ramishrastevebaker: anyway, there would be docker-compose fedora package sometime soon, they have an earlier 'fig' package atm04:06
stevebakerramishra: looks like they're pinning to exact versions https://github.com/docker/compose/blob/master/requirements.txt04:07
ramishrastevebaker: yeah!04:07
ramishrastevebaker: It does not work for requests>=2.5.3, works for less than 2.504:08
stevebakerramishra: can you pip install --no-deps? (and pip install any required deps manually)04:09
ramishrastevebaker: yeah, I think I tried that, it does not work.. docker-compose breaks with 2.5.304:10
stevebakerugh, they should fix that04:10
ramishra I think its because of docker-py https://github.com/docker/compose/issues/91804:11
*** nkhare has joined #heat04:12
*** nkhare_ has joined #heat04:12
stevebakerramishra: you could always pip install all the things. It might be easier to get os-collect-config working with older requests heat-templates/hot/software-config/boot-config/templates/fragments/install_config_agent_pip.sh04:12
ramishrastevebaker: that's what we did earlier before moving to fedora packages, we moved to yum to reduce the size of image:)04:13
stevebakerlol, oh yeah04:14
stevebakerwell, working and big beats broken and small04:14
ramishrabut, we can use the binary install of docker-compose, we'll move pip install later, when it's fixed. should be ok right?04:15
stevebakercouldn't we try pip install with pip install of os-collect-config etc?04:16
ramishrayeah, it requires gcc and other xml/xlst stuff, we can do that, but my guess it would increase the size..04:17
stevebakerah, thats where my cleanup stuff would come in handy https://github.com/steveb/docker-heat-templates/blob/master/docker/heat-base-standalone/install-heat.sh#L3404:18
ramishraIMO, we may have to look for something like busybox or some light os for container-agent . the size should be minimal like weave or socketplane < 20MB, >500 MB is still too big.04:20
stevebakeryeah agreed04:20
stevebakersurely someone at redhat is working on tiny container base images04:21
ramishrahopefully;) the size of atomic with all kubernetes, docker and flannel is > 400 MB :)04:22
stevebakerlets stop optimising image size for now, and work on that later. I won't object if you install binary docker-compose04:22
ramishrabtw, I've added the logic to pull the image from http server..04:23
stevebakeroh, sweet04:23

Qimingstevebaker, I am trying to inject a script into a VM and have it executed just like a backgroup service05:42
Qimingto avoid building custom images as required by users, I'm not using softwareconfig or any os-*-config packages05:43
Qimingany suggestions how I can 1) pass stack user id/password into the vm, 2) daemonize the script so that it will get executed periodically?05:44

zanebinc0: o/16:26
inc0o/ I've read through your mail about upgrades of overcloud16:27
inc0probably I'll be able to help you with this in L - I'm kinda involved in openstack upgrades thing16:27
zanebok, cool16:27
inc0I'm concerned if this isn't a bit too simplistic approach16:28
zanebbtw we've decided not to try to drive through the ResourceGroup -> AutoscalingGroup change right now16:28
inc0just softwareconfig?16:28
inc0well...making ASG as core for upgrades seems...counterintuitive16:29
zanebso maybe we need to distinguish between updates & upgrades here16:29
zanebthe thread was only about (package) updates16:29
zanebnot about e.g. Juno->Kilo or Kilo->Liberty upgrades16:29
inc0yeah, but whole release upgrade will use it16:29
inc0yeah, I'm concerned about releases16:29
zanebyeah, that will be a much more complex process16:30
inc0yeah, (just to keep kombo going) release upgrade will be harder, but might consist this package upgrade16:31
inc0if we consider kolla container as a package...of sort16:31
zaneba full release upgrade will probably involve replacing disk images16:32
inc0that might not be possible16:32
inc0if we'll want rolling upgrade to happen16:32
zanebas well as db migrations and all sorts of other fun stuff16:32
*** ashishjain has joined #heat16:32
inc0yup16:32
*** ashishjain has quit IRC16:33
inc0removing stuff from compute which we want to work on, shut down controller services we want to upgrade and so on16:33
zanebthere's no particular reason I'm aware of that we couldn't do an image replacement in a rolling fashion16:34
*** Tross has joined #heat16:34
zanebthough there may be one16:34
inc0when for some reason we can't turn off compute16:34
zanebit's not a subject I have looked into deeply yet16:34
inc0for example because stuff on it is too important to turn off, and we can't perform live migrate for some reason16:35
zanebwe can evacuate compute hosts16:35
inc0not without vm downtime16:35
inc0I'm thinking pets here - something we can't freely kill16:35
zanebis there no way to live migrate?16:36
inc0there can be16:36
inc0no shared storage, heavy memory usage16:36
inc0not enough network bandwith16:36
inc0LM is kinda expensive to maintain16:37
inc0can be at least16:37
*** Tross has quit IRC16:37
inc0also I don't think cinder allows you to live migrate your volume16:38
*** pm90_ has quit IRC16:39
inc0so for example if you're public cloud vendor and you can't just disconnect someones volume...you're kinda screwed16:39
inc0(not as screwed as if your host accidently blow up, but screwed nonetheless)16:39
zanebzero-downtime, avoiding live migration and applying updates are mutually incompatible. you can have at most 2 out of 316:42
*** derekh has quit IRC16:43
inc0well, true, but still having just image replace scenerio isn't very convenient16:44
inc0good approach to upgrade would be for example per-service upgrade16:44
inc0first nova, then keystone and so on16:45
inc0image replace wouldn't allow that approach16:45
*** Marga_ has joined #heat16:46
*** Marga_ has quit IRC16:46

inc0I'll try to bring few people from ops side to the table as well - upgrading stuff isn't new16:48

sirushtiHi zaneb, if you've got some time, could you take a look at https://review.openstack.org/#/c/159774/, https://review.openstack.org/#/c/159444/, https://review.openstack.org/#/c/167324/17:05

sirushtizaneb, sure. Also, I have a question related to check-workflow. Shouldn't we check if the stack is complete in a delete traversal in convergence-check-workflow? The POC code suggests that we only do it for the forward traversal17:08

zanebsirushti: sorry, lots of context to reload here ;) can you point at the part of the code you're referring to?17:11
*** serg_melikyan has quit IRC17:12
sirushtizaneb, heh :) here you go -> https://github.com/zaneb/heat-convergence-prototype/blob/master/converge/converger.py#L112-L11417:12
zanebah, gotcha :)17:12
zanebin the simulator I made the decision to move the state to COMPLETE as soon as all of the new stuff is operable, and not wait for the clean-up17:13
zanebI still have mixed feelings about this17:13
zanebbecause it's a change in existing behaviour17:14
*** sdake_ has joined #heat17:14
sirushtizaneb, hmmm, so we really need a way of setting DELETE_COMPLETE17:15
zanebhttps://github.com/zaneb/heat-convergence-prototype/commit/d2be14d2f711ece927cbf0f9382d744a3e881d4c17:16
zanebsirushti: yes, you're right. so at a minimum we need to add something similar to indicate when the clean-up is complete17:16
zaneband arguably that should be the only thing we have. that part is probably worth a mailing list discussion & a possible follow-up at Summit17:17
*** sdake has quit IRC17:18
sirushtizaneb, yeah, I was just wondering if we should've just done check_stack_complete for both traversals. This explains a lot.17:19
*** SaD has joined #heat17:19
*** SaD has quit IRC17:19
zanebsirushti: iirc my original plan was not to implement any state-changing stuff at all in the simulator, but then I had to to test some other features but I only did the minimum to get that to work, hence the stuff for the cleanup phase is missing17:22
sirushtizaneb, sure no problem, I'll take a look into figuring out the implications of ^setting-state-early more. Thanks a lot.17:28

*** dyasny has joined #heat19:35
dyasnymorning all. Can anyone please provide an estimate on how hard it would be to use standalone heat as an orchestration engine for a non-openstack platform? I'm especially troubled by the ceilometer connection, how hardwired are those?19:36

*** alexheneveld has joined #heat19:57
zanebdyasny: moderately hard, but the ceilometer connection is actually the easiest bit20:01
*** achanda has quit IRC20:01
dyasnyzaneb, I'm just starting out, getting a VM set up for an initial heat standalone setup20:04
*** sdake_ has joined #heat20:05
dyasnyzaneb, if you have clues/ideas/links/whatever, that'll be a great help20:05
zanebdyasny: you'll need custom resource types that talk to whatever your infra platform is (what is it) and a way to authenticate other than keystone20:06
*** serg_melikyan has quit IRC20:06
zanebbut the ceilometer autoscaling input is just a simple webhook20:07
dyasnyzaneb, hmm, I wonder whether it'll be easier to just write my own parser to those stack yaml files20:07
*** sdake has quit IRC20:07
dyasnyzaneb, it kinda makes sense to use a ready engine, like heat, but I prefer not to generate extra work for myself, this shouldn't be too complex20:08
dyasnythe platform id oVirt20:08
dyasnys/id/is/20:08
zanebdyasny: then you're definitely going down the wrong path imho20:08
dyasnyzaneb, what do you mean?20:08
zanebdyasny: if you want something that is not too complex and doesn't generate extra work for yourself, using Heat as a front-end for oVirt is not it20:09
dyasnyzaneb, not front end20:09
dyasnyzaneb, a side engine that monitors ovirt via api and scales stacks as needed20:10
dyasnyzaneb, I can script this using the ovirt SDK pretty easily, but heat is already there and it already has a nice template format and a parser. daemons are already done too. problem is, I don't know it deeply enough to figure out whether getting standalone heat to work with ovirt is worth the effort saved on not developing a template engine and stack load monitoring daemon20:13
