SlowerOK, what's the M1 goal then?23:01
Slowermmmm, pizza23:01
Slowerya my phone never adjusted the meeting for the TZ.. I guess I put the time in in PDT so that makes sense23:01
adrian_ottomine too, and I know better23:02
sdakeadrian_otto are you oepning the thread on the ml re milestone #1?23:03
achanda_do we know when do we want M1 to end? the scope should depend on the time we have..23:03
sdakelikely need 3 weeks for that level of work23:04
Slowerpersonally the time should just be a guideline.. if we go over it's not a big deal imo23:04
adrian_ottodguryanov, abhishek-i, dims, Slower, please DM me your email addresses23:04
sdakedec 8th23:04
Sloweradrian_otto: PM?23:04
dimsadrian_otto: you have mine23:04
achanda_sdake: ok23:05
adrian_ottodims: got it, tx!23:06
sdakei'm still a bit fuzzy on bays23:07
Slowersdake: what do you need to know?23:07
sdakeassume i have a 10k physical node count cluster23:08
sdakewhat software is running on each node to provide the bay on bay create23:08
sdakesome type of agent?23:08
SlowerI think basically we are planning to use nova-docker to spin up a docker image containing our service23:08
Slowernova23:08
sdakenova-docker is single node tho?23:08
Slowernova-docker is a driver for nova that creates docker containers23:08
adrian_ottoall new cores have been added to: https://review.openstack.org/#/admin/groups/473,members23:09
sdakeone issue with nova-docker that iwll be incredibly challenging is implementing pod networks23:09
sdakeslower so not using nova-docker would be better ;)23:09
Slowersdake: can we talk that through?23:09
Slowersdake: you are probably right, I'm just not sure yet23:09
sdakea pod shares a network23:09
SlowerI'm not sure how networking will work with containers-within-containers23:10
sdakepods dont have to be contaiuner in container23:10
sdakepods can be bare metal container beside container23:10
Slowerbasically we will be starting a container with our service + docker or k8s23:10
sdakethat is how k8s implements it23:10
Slowersdake: they can yes23:10
Slowersdake: I think it depends on where and how we want to integrate with openstack23:11
Slowersdake: if we want to provide a new openstack service that runs along side nova then we can do that23:11
Slowerif we make use of nova-docker then the new service can be an image23:11
Slowerand admins don't need to install anything new (if they already have nova-docker)23:11
Sloweror they can use vms23:12
sdakei am pretty sure we wont ever be able to get  the networking to work with that model :)23:12
Slowersdake: do you know how container in container works?23:12
Slowernetworking23:12
sdakeno23:12
SlowerI mean23:12
Slowerme neither :)23:12
sdakedaneyon can sort it out I think23:12
sdakebut what makes more sense is container BESDIES container23:12
sdakenot in container23:12
sdakenesting sucks :)23:12
Sloweryou should tell erw that :)23:13
* Slower envisions a matter/anti-matter collision23:13
daneyonI would think container in container is simply layered linux bridges.23:13
sdakeso container in container is easy daneyon?23:13
sdakeI am certain k8s does not use nesting23:14
SlowerI doubt they would23:14
sdakethey somehow set up the networking on the pod on the bare metal23:14
daneyonAt the surface it seems straight forward. Of course, we'll know better when we dig deeper.23:14
Slowerwe are just using it because it makes it easy to integrate into openstack23:14
Slowersdake: there's no question you can do it without23:15
Slowerthis just lets us make a nice tidy docker image that does what we want and offers our service23:15
adrian_ottoin a pod, there is a single network namespace, and multiple containers within the pod use that same one23:15
sdakeright23:15
Slowerbay != pod23:15
Slowerwe are not nesting for pods sake23:15
Slowerit's just how we are integrating with openstack23:15
Slowerand if that doesn't work we can figure out how to do it without that23:16
Slowerbut I think if it does work it will be slick23:16
Yuanying_bay = container (provided nova-docker) or vm (provided kvm) or bare metal (ironic) ?23:17
SlowerYuanying_: correct23:17
sdakeironic can schedule like that?23:17
sdakeeg, you can put ironic on every machine and ask for a bay from ironic, and it will find one?23:17
Slowerfyi it's all a silly ocean analogy.. bay (ocean bay) -> pod (of whales) -> containers (on whales backs)23:18
sdakeya i get its a higher level abstraction23:18
sdakejust wondering how its implemented :)23:18
sdakespecifically the comes from ironic case23:18
sdakeI dont know much about ironic at all23:18
Slowersdake: hmm, that might be trickier.. I don't know how you define the image running in ironic instances23:18
Slowerbut if we included our service in the ironic image then it would work23:19
sdakeright you need to run something there23:19
sdakethis is the agent I spoke of earlier :)23:19
sdakeagent on every machine, no need for nova-docker or ironic23:19
Sloweryeah23:19
Slowerso that would be a service parallel to nova23:19
Slowerwe can explore that too23:20
SlowerI don't think it will be hard to change it later if we want23:20
sdakeyou say paraplell to nova, what else would there be?23:20
Slowersdake: if we make a docker image containing the service, the admin doesn't need to manage it as an openstack component directly23:20
Sloweryou start it via nova-docker23:21
*** harlowja_away is now known as harlowja23:21
*** zul has quit IRC23:21
sdakeso nova-docker is on each node?23:21
Slowerit's part of nova (or will be)23:21
Slower(or will have to be installed by the admin if it doesn't get included as core nova)23:22
sdakelet that melt my brain for a minute23:22
sdakebbiaf23:22
Slowerok :)23:22
Slowersdake: it took me a month or more to absorb it :)23:22
Yuanying_If I have a vm image containing the service, I can use it ? or any limitation now?23:22
sdakeok got it, so agent runs in each nova-docker container23:22
sdakeand that handles the rest api23:23
sdakethat means no installing the service in bare metal23:23
Slowersdake: correct23:23
SlowerYuanying_: correct.  This is just all ideas right now23:23
sdakefor that model to work we need a server to communicate with the rest api23:24
Yuanying_thx23:24
sdakeand the server needs to run in each nova driver23:24
sdakeerr each image that hte nova driver launches23:24
Slowersdake: can we find endpoints via keystone?23:24
sdakethe server then provides pod and container scheduling23:24
sdakeseems like neeedless complication but I like complex thing s:)23:25
*** Yuanying_ has quit IRC23:25
Slowerhaha23:25
Sloweryou may be right23:25
sdakeI can tell you it will not scale well23:25
sdakeeg 10k nodes forget about  that23:25
erwsdake: nesting vs pseudo-nesting is technically an implementation detail23:26
sdakeerw yup you may be right23:26
erwsdake: more importantly, imho, is that nesting makes sense as a logical model23:26
sdakewell i haven't said bays aren't a good idea - i like that idea in fact23:27
sdakebut the nesting part of it seems concerning23:27
erwsdake: that said, a multi-tenant system with a single docker daemon is far more vulnerable than a multi-tenant system with nested docker23:27
sdakei'm not sure how to put my fingero n it23:27
erw(then again, both are fairly fragile security-wise)23:27
sdakei guess I need to read the ironic api23:28
erwsdake: their api is the nova api, isn’t it?23:28
erwbbl- again.23:28
sdakeno clue at all23:29
Slowerironic is a nova driver23:29
Slowerjust like nova-docker23:29
Slowerthe only thing different I think would be the image format23:29
sdakeand it boots an image on bare metal?23:29
Sloweryeah23:29
Slowerpxe boot I think23:29
sdakehow does it maintain contact?23:29
sdakeafter it b oots23:29
Slowerdunno :)23:29
Slowercloud-init? :)23:29
sdakei would think its image would be gone23:29
SlowerI'm guessing23:29
Slowerafaik it's only really used for triple-o23:30
