| SpamapS | mordred: right, and I'm with lifeless.. I want "something that resolves and is meaningless to what the server does" | 00:00 |
|---|---|---|
| mordred | sure. that's a great goal | 00:00 |
| mordred | but since nova isn't plubmed to dns, I'd like it to not subvert my attempts to set it to meaningful things | 00:00 |
| SpamapS | Because otherwise you need DNS as a service and something to guarantee unique hostnames globally.. allow reservations.. etc. etc.. | 00:00 |
| SpamapS | I seem to recall there is a non-default setting one can do to have it apply a pattern and ignore the 'name' nova boot was given | 00:01 |
| *** rsachary- has joined #tripleo | 00:01 | |
| mordred | so, actually, doesn't cloud-init set the hostname from the metadata? | 00:02 |
| lifeless | it does | 00:02 |
| mordred | one would think, then, that both of us could be satisfied based on some sort of selectable choice | 00:02 |
| SpamapS | right so I am digging into this right now because my review brain is jet lagged.. but I think there's a setting to make it not do that. | 00:02 |
| SpamapS | err | 00:03 |
| SpamapS | to make nova not set the hostname in metadata to "name" | 00:03 |
| mordred | SpamapS: it's certainly not a consumer-visible option that I am aware of - I believe there might be a deployer option | 00:03 |
| mordred | SpamapS: honest to god though, I'm not trolling, when you're not jet lagged and when lifeless is not busy, I REALLY honestly want to understand the thinking | 00:04 |
| *** ftcjeff has quit IRC | 00:04 | |
| mordred | becase, as a consumer of cloud resources quite regularly, it's exactly the opposite of what I want | 00:04 |
| mordred | so I want to understand what I might be missing | 00:04 |
| SpamapS | mordred: right, I"m thinking deployer option | 00:05 |
| lifeless | mordred: so as a DC operator, we want things like 'hostname maps to physical location' | 00:05 |
| *** CaptTofu has joined #tripleo | 00:05 | |
| lifeless | mordred: or to 'CMDB record' | 00:05 |
| mordred | because it's possible that if I reframed my thinking on my problem space, perhasp something will become easier for me | 00:05 |
| lifeless | mordred: for troubletickets communications etc. | 00:05 |
| SpamapS | mordred: and the deployer option dhcp_domain is already a little bit WTF.. | 00:05 |
| mordred | lifeless: yah - but couldn't you set that as the name you pass to nova boot? | 00:05 |
| mordred | (asking for real, trying to understand space) | 00:05 |
| lifeless | mordred: logical service -> host that something is running on is a separate layer in DNS etc for /this reason/ | 00:05 |
| lifeless | mordred: no, you can't, because you don't know the node the thing will deploy to. | 00:06 |
| lifeless | mordred: nova knows. | 00:06 |
| mordred | ok. I think we're talking about two different things, and I'm sorry for that | 00:06 |
| lifeless | mordred: likewise, when you ring rackspace, and you've got 40 nodes called 'jenkins.o.o', which one will they try to fix? Ah - the UUID will tell them. | 00:06 |
| * mordred was going to disengage before SpamapS kept talking :) | 00:06 | |
| lifeless | SRV vs CNAME vs A. | 00:07 |
| lifeless | I'm all for switching DNS around to rotate boxes in and out, but thats got nothing to do with what the identity of the box is. | 00:07 |
| lifeless | physical or virtual | 00:07 |
| lifeless | mordred: I know, I blame SpamapS too | 00:07 |
| mordred | if you set the fqdn of the host as it sees itself to something related to random or uuid or something other than its logical name | 00:07 |
| mordred | puppet will break completely | 00:08 |
| mordred | as in, it's 100% not possible to use it | 00:08 |
| lifeless | mordred: puppet supports an override for this (for this reason) | 00:08 |
| lifeless | mordred: which for your use case as described, I would feed in in the nova metadata | 00:08 |
| mordred | but I did. I said "nova boot foo.bar.com" | 00:08 |
| lifeless | mordred: and then you said 'and that affects hostname' and lost | 00:09 |
| mordred | ok. look | 00:09 |
| lifeless | I would pass that name in - yes, and use it for puppet - yes, have it set hostname - no. | 00:09 |
| mordred | I'm saying "hi, I run a large cloud based application, and the behavior causes me pain" | 00:09 |
| lifeless | I don't get what I want, but thats what I want. | 00:09 |
| mordred | and, just like the hp pulic cloud people, you're telling me that I'm just flat wrong | 00:09 |
| mordred | I'm saying that there should be a way for me to ask nova to pretty please set the damned hostname | 00:10 |
| mordred | because I might have a different worldview | 00:10 |
| lifeless | ok, sorry. I'm trying to tell you that a) I've seen that pain and b) I've seen the pain the middle house everyone other than AWS does and c) I solved that pain in a way that scales, doesn't introduce support problems | 00:10 |
| lifeless | and that I like | 00:10 |
| lifeless | mordred: you can of course to whatever-you-want to hostname in your instance | 00:10 |
| mordred | great. I'm honestly thrilled there is a better way to scale the information system | 00:11 |
| mordred | what I'm saying is that I'd like to be able to ask nova to set the hostname to what I requested, rather than what I requested + novalocal - and I'd like to not then just have to follow up the boot with "ssh host ; hostname $hostname" because that's lame | 00:11 |
| mordred | but, we shodl have disengaged from this a while ago | 00:11 |
| mordred | :) | 00:11 |
| lifeless | SpamapS: the setting you're looking for is #dhcp_domain=novalocal | 00:11 |
| lifeless | which is a deployer setting, one off, affects every node using that API server | 00:12 |
| lifeless | so essentially its per-region | 00:12 |
| lifeless | mordred: user metadata scripts can do that setting for you during first boot | 00:13 |
| lifeless | mordred: I think my point is that wearing my ops hat, the *very last* thing I ever want is two shells to look like the same machine | 00:14 |
| lifeless | mordred: because sudo poweroff on the wrong box is bad | 00:14 |
| lifeless | mordred: so I have a visceral OMG WHY WOULD YOU DO THAT reaction | 00:15 |
| lifeless | quite apart from anything else | 00:15 |
| *** NearlyFunctional has quit IRC | 00:16 | |
| mordred | I hear that - I really do | 00:19 |
| mordred | I guess the thing that irks me is that there are a bunch of simple cases that this behavior makes much harder than they need to be | 00:20 |
| mordred | sure, if you have 100 nodes that share a role, awesome | 00:20 |
| mordred | a lot of the time, I'm spinning up one server for one thing, and the fact that I have to then shell in and set the hostname even though I knew what I wanted it to be first | 00:21 |
| mordred | is irksome | 00:21 |
| mordred | if I wanted to do more complex hostname management, I'd do that myself at deployment time | 00:21 |
| mordred | and user metadata scripts are not helpful, because there is almost nothing I've been able to use them for anyway | 00:21 |
| mordred | again - if the problem was more complex, I'm sure they'd be a great answer | 00:22 |

| mikal | Hmmm | 02:26 |
| lifeless | mikal: there are patterns for doing fancy things, but they fail the simpleness test. | 02:26 |
| mikal | I started with just hiding the bits I had in a module | 02:26 |
| ccrouch1 | (2:51:09 PM) lifeless: -> storage_config: {'swift': 100, 'cinder': 50} - 2/3 swift, 1/3 cinder | 02:26 |
| ccrouch1 | from our conversation earlier | 02:26 |
| ccrouch1 | i see how this support the case of swift and cinder being colocated, but how would you indicate you wanted cinder to use all available disks when its deployed on its own node and swift to use all available partitions when it is deployed on its own node? | 02:26 |
| mikal | But decided that a singleton would be less ugly | 02:26 |
| mikal | I think you're saying plan A is more pythonic | 02:27 |
| lifeless | mikal: I think an object is fine | 02:27 |
| lifeless | mikal: for instance | 02:27 |
| lifeless | class Bar: .... | 02:27 |
| lifeless | the_one_true_bar = Bar() | 02:27 |
| mikal | Oh I see | 02:27 |
| mikal | Yeah, that would work | 02:27 |
| lifeless | mikal: then, if youneed to test the behaviour of the thing, you can make a new what etc | 02:27 |
| lifeless | mikal: but its not super fancy | 02:28 |

| ccrouch1 | thats why i was confused about moving this "higher" up in the template | 02:30 |

| lifeless | at which point the libvirt call is meant to return and we should be active | 03:30 |
| StevenK | lifeless: And nova is supposed to kill the source instance and then forget about it? | 03:32 |
| lifeless | the default flags are | 03:32 |
| lifeless | #block_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE, VIR_MIGRATE_PEER2PEER, VIR_MIGRATE_NON_SHARED_INC | 03:33 |
| lifeless | StevenK: no, libvirt kills it | 03:33 |
| lifeless | nova is mean to undefine it | 03:33 |
| lifeless | the flags I used are block_migration_flag=VIR_MIGRATE_LIVE,VIR_MIGRATE_TUNNELLED,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_NON_SHARED_INC | 03:33 |
| lifeless | note the _LIVE which is what tells libvirt to do the right thing | 03:33 |
| StevenK | lifeless: I note there is a VIR_MIGRATE_UNDEFINE_SOURCE missing | 03:34 |
| lifeless | yeah | 03:34 |
| lifeless | I'm not sure why | 03:34 |
| lifeless | this is why I've been reading libvirt sources today | 03:34 |
| lifeless | but, its C time now | 03:34 |
| StevenK | So maybe that's why it is hanging around | 03:34 |
| lifeless | StevenK: the thing is why *nova* hasn't realised | 03:35 |
| lifeless | that concerns me | 03:35 |
| StevenK | lifeless: My point is perhaps nova is expecting libvirt to do so, and it hasn't done so due to no VIR_MIGRATE_UNDEFINE_SOURCE flag | 03:35 |
| lifeless | StevenK: I agree that that is a good point :) | 03:36 |
| lifeless | StevenK: as for more patches for you, I had something. Oh right, I think pushing on xtradb cluster is probably back top of the list - or joining me on this live migration arc | 03:37 |

| lifeless | there it is | 05:35 |
| jog0 | clarkb: https://wiki.ubuntu.com/Testing/EnableProposed | 05:35 |
| StevenK | I was guessing based on obversed behaviour | 05:35 |
| jog0 | lifeless: is that a live migrate working? | 05:35 |
| lifeless | jog0: yes | 05:35 |
| jog0 | lifeless: most impressive | 05:36 |
| lifeless | StevenK: I know, strength of many eyes | 05:36 |
| lifeless | now to propose a fix to nova to fix the defaults | 05:36 |
| jog0 | lifeless: ++ | 05:36 |
| lifeless | wait for 12 years for some old supported platform to go out of support | 05:36 |
| lifeless | and then fix it | 05:36 |
| * jog0 looks at the time and signs off | 05:36 | |
| lifeless | the live migrate default also doesn't specify live migration | 05:37 |
| lifeless | which is bong, but a thing for another day | 05:38 |
| * SpamapS awakens | 05:38 | |
| lifeless | StevenK: if you're interested - | 05:43 |
| lifeless | https://review.openstack.org/74600 | 05:43 |
| clarkb | I will try proposing devstack change tomorrow. I really want new libvirt | 05:46 |
| SpamapS | in soviet russia, new libvirt really want YOU | 05:49 |
| clarkb | we can kill nova site packages venvs with it | 05:49 |
| lifeless | clarkb: oh, its pip installable? | 05:55 |
| lifeless | clarkb: why don't you just try that? | 05:55 |
| clarkb | the python bindings are with newer C libvirt | 05:56 |
| clarkb | you need the distro package first though | 05:56 |
| StevenK | lifeless: So, something about nodes: [] in the JSON. | 05:57 |
| StevenK | lifeless: What am I missing that we don't need defaults in the JSON? | 05:58 |
| lifeless | StevenK: where do we use the defaults | 05:58 |
| SpamapS | clarkb: the cloud archive beckons? ;) | 05:58 |
| clarkb | SpamapS after we convince ubuntu to backport the fix from proposed | 05:59 |
| lifeless | apply | 05:59 |
| lifeless | not backport ;) | 05:59 |
| *** coolsvap1 has joined #tripleo | 05:59 | |
| StevenK | lifeless: _seed for setup-baremetal ; _testenv uses creates-nodes to get MAC address ; _undercloud also uses setup-baremetal | 05:59 |
| SpamapS | clarkb: ah, in that case, -proposed beckons! | 05:59 |
| lifeless | StevenK: testenv /makes/ the JSON | 06:00 |
| SpamapS | clarkb: is there a bug attached? Test it and post on the bug, that is usually all it takes to enable the copy to -updates | 06:00 |
| openstackgerrit | Richard Su proposed a change to openstack/tripleo-incubator: Enable horizon on overcloud control node https://review.openstack.org/74603 | 06:00 |
| lifeless | setup-baremetal needs the node data, not defaults. | 06:00 |
| SpamapS | Technically I still have powers to do that. | 06:00 |
| SpamapS | though I'm inactive in ubuntu-sru and should probably self-remove | 06:00 |
| lifeless | the seed architecture baked into the config should be pulled from the testenv | 06:00 |
| clarkb | SpamapS see sb :) | 06:00 |
| StevenK | lifeless: Right. Now I get it. testenv happens before seed | 06:01 |
| StevenK | lifeless: So, _testenv needs defaults, then? | 06:01 |
| lifeless | StevenK: yes | 06:01 |
| clarkb | SpamapS there is and I eill write a devstack change to test it | 06:01 |
| StevenK | But they don't hit the JSON, only nodes: [] gets populated? | 06:01 |
| lifeless | StevenK: uhm, so I think you'll find corners, but we should work through them as you do | 06:02 |
| *** e0ne has joined #tripleo | 06:02 | |
| lifeless | StevenK: in general think about it this way | 06:02 |
| lifeless | StevenK: I have 50 machines, possibly heterogeneous | 06:03 |
| lifeless | StevenK: but (for now anyhow) same arch | 06:03 |
| *** coolsvap has quit IRC | 06:03 | |
| lifeless | StevenK: I want to capture all that data in a sane machine readable form | 06:03 |
| lifeless | [ipmi power mac memory disk etc] | 06:03 |
| lifeless | StevenK: and the run devtest and make a seed vm, use it to deploy an undercloud on one real machine and a virt cloud on the reset | 06:03 |
| lifeless | s/reset/rest/ | 06:04 |
| StevenK | lifeless: Right. | 06:04 |
| StevenK | lifeless: I think this will require toci changes | 06:04 |
| lifeless | StevenK: so - specifically - flavor creation probably needs to become introspective and be based on the sizes in the json and perhaps make multiple flavors | 06:04 |
| StevenK | And probably a revert of the node-cpu stuff | 06:04 |
| lifeless | StevenK: sure, but lets start with incubator | 06:04 |
| lifeless | StevenK: in the sense of defining it | 06:04 |
| lifeless | StevenK: with the variables as backwards compat | 06:05 |
| lifeless | StevenK: changing toci is straight forward [in fact, toci needs to start calling testenv to make its environments] | 06:05 |
| lifeless | [in the host, not in the test job] | 06:05 |
| StevenK | Right, which depends on the -incubator changes | 06:06 |
| lifeless | zigactly | 06:06 |
| StevenK | lifeless: So I think I'm clear enough to make a start on this tomorrow morning | 06:06 |
| lifeless | thus doing it in incubator first :) | 06:06 |
| lifeless | StevenK: wseet | 06:06 |
| StevenK | I may write a handler to write out the jSON | 06:07 |
| StevenK | *JSON | 06:07 |
| lifeless | StevenK: cool | 06:07 |
| lifeless | StevenK: there is a python script already; it could be nicer:) | 06:07 |
| SpamapS | lifeless: FYI, I think I understand the push toward a json file vs. env vars now btw. | 06:07 |
| lifeless | SpamapS: cool | 06:08 |
| SpamapS | It makes me want bash to have built in json | 06:08 |

| SpamapS | oh.. hosts entries for all others.. interesting... | 06:12 |
| lifeless | SpamapS: yes, this is why I've been against env variables in the broad sense, but without good answers, for a while | 06:13 |

| lifeless | SpamapS: we'd have yet another yak. | 06:21 |
| lifeless | SpamapS: one that talks back | 06:21 |
| SpamapS | lifeless: so having a hosts file with all nova nodes seems like a harder thing than having DNS updated... | 06:22 |
| lifeless | SpamapS: I mean I'm not against deploying designate in the undercloud | 06:22 |
| lifeless | SpamapS: but | 06:22 |
| SpamapS | lifeless: having a hosts file with _most_ nodes... that is more doable. | 06:22 |
| lifeless | SpamapS: whats the diff ? | 06:22 |
| lifeless | SpamapS: I just need a couple of str joins across the defined compute nodes | 06:22 |
| SpamapS | lifeless: we'd have to have wait conditions that wait for boxes to update hosts files before we can do any live migration. | 06:23 |
| lifeless | SpamapS: when a box checks in to say its ready, that would be included | 06:23 |
| lifeless | SpamapS: no special machinery is needed | 06:23 |
| SpamapS | lifeless: I'm thinking at scale this breaks down... I'm not sure we can ever assume all compute nodes are in the same stack. | 06:23 |
| lifeless | SpamapS: ok, so I'm thinking of doing no-downtime deploys today :) | 06:24 |
| SpamapS | another option is to just scrape all of nova into a hosts file for everybody. | 06:24 |
| lifeless | SpamapS: I don't care if its global | 06:24 |
| SpamapS | but yeah, we can just join up all the names and addresses | 06:26 |
| lifeless | SpamapS: here is what we need | 06:26 |
| SpamapS | and then when we have multiple stacks, accept a similar string to append.. | 06:26 |
| SpamapS | and produce one as an output.. | 06:26 |
| lifeless | 10.10.16.147 overcloud-novacompute0-pvxacl6m7vvt.novalocal overcloud-novacompute0-pvxacl6m7vvt | 06:26 |
| lifeless | note the two entries | 06:26 |
| SpamapS | Yeah I think that is pretty doable | 06:26 |
| *** cadenzajon has quit IRC | 06:26 | |
| lifeless | SpamapS: can you do it ? | 06:26 |
| SpamapS | lifeless: yeah, do we already have the hosts file append thing worked out? | 06:27 |
| lifeless | then we can close this ticket and I can move onto the control plane with jprovzn and greg | 06:27 |
| lifeless | SpamapS: yes | 06:27 |
| SpamapS | ok I thought so.. | 06:27 |

| lifeless | SpamapS: any reference to stuff that scales outside of the context of a scaling thing will also scale | 06:34 |
| lifeless | SpamapS: so a independent top level dict | 06:34 |
| lifeless | SpamapS: should get that list of names trivially | 06:34 |
| *** matsuhashi has quit IRC | 06:35 | |
| SpamapS | So an Fn::Select: [ 0 , {Fn::Select: [ Fn::GetAtt: [ NovaCompute0, networks ] ] } ] will be duplicated? | 06:35 |
| lifeless | In that situation | 06:36 |
| lifeless | NovaCompute0 will be replicated | 06:36 |
| lifeless | I was assuming you'd define the list of things to lookup in one place | 06:36 |
| lifeless | like | 06:36 |
| lifeless | compute=[NovaCompute0] | 06:37 |
| lifeless | which will expand to compute=[NovaCompute0,NovaCompute1, ...] | 06:37 |
| *** matsuhashi has joined #tripleo | 06:37 | |
| SpamapS | I don't think the functions can do that | 06:37 |
| SpamapS | lifeless: this has been my frustration with cfn language as a whole.. it does not have a notion of arrays | 06:37 |
| lifeless | there's no map ? | 06:37 |
| SpamapS | not that I can find | 06:38 |
| SpamapS | I've wanted such a thing for a while though | 06:38 |
| SpamapS | so it might be worth adding. :p | 06:38 |
| lifeless | theres Fn::FindInMap | 06:38 |
| SpamapS | Those are for finding one in a map of many | 06:38 |
| SpamapS | we need one for each part of a list | 06:39 |
| SpamapS | the mappings are for making things portable | 06:39 |
| SpamapS | AFAICT | 06:39 |
| lifeless | ah yes | 06:40 |
| lifeless | but | 06:40 |
| lifeless | we want to strjoin | 06:40 |
| lifeless | starts ove | 06:40 |
| lifeless | we want to | 06:40 |
| lifeless | strjoin | 06:40 |
| lifeless | a bunch of one line hosts definitions | 06:40 |
| lifeless | each of which looks identical | 06:40 |
| lifeless | but refers to a different novacomputeN | 06:40 |
| lifeless | merge.py will do this if there is a containing dict that matches NovaCompute0 | 06:41 |
| SpamapS | also I believe the mappings part of CFN is pre-parsed.. so it can't refer to attributes | 06:41 |
| SpamapS | as I tried to do that early on with something similar | 06:42 |
| SpamapS | lifeless: it might not be that hard to have a map function really | 06:42 |
| lifeless | so really, I think a map is going to be the right way | 06:43 |
| lifeless | refs or not, anything I come up with wants to map | 06:43 |
| SpamapS | yep | 06:43 |
| SpamapS | we can do it with this and then later have resourcegroup/instancegroup/autoscalegroup produce lists of members and that will allow the bits that use our map function to stay stable as we move to groups instead of merge.py scaling. | 06:43 |
| lifeless | so Join is a map of sorts | 06:44 |
| SpamapS | and if we can't land map in heat immediately we can fake it in merge.py.. but I will try really hard not do do that. ;) | 06:44 |
| lifeless | ok | 06:44 |
| lifeless | I'll leave it with you | 06:44 |
| lifeless | and turn my baleful eye on the control plane | 06:44 |
| SpamapS | Ok.. I'm going to do a bit of waking up and breaking fast.. | 06:44 |

| SpamapS | jprovazn: you can only get their addresses | 13:59 |

| SpamapS | jprovazn: https://git.openstack.org/cgit/openstack/tripleo-heat-templates/tree/undercloud-source.yaml#n134 | 13:59 |
| SpamapS | jprovazn: I know.. I told you to use the hostnames. ;) | 13:59 |
| SpamapS | jprovazn: but you _CAN_ get their _nova_ names | 14:00 |
| SpamapS | jprovazn: which should be their hostnames.. | 14:00 |
| jprovazn | SpamapS: yep, istance_name works | 14:00 |
| jprovazn | but it's not their hostname | 14:00 |
| SpamapS | jprovazn: for that, just Fn::GetAtt: [ resource_name, name ] | 14:00 |
| jprovazn | it's "instance-xxxx" | 14:00 |
| SpamapS | no it should be the name that is used to make the hostname | 14:00 |

| jprovazn | SpamapS: when you are back... because instance_name != hostname, I think it makes sense to set NODENAME for rabbitmq server - then any name can be used and it's up to heat template if it uses instance_name, user-defined name or anything else. What do you think? | 14:20 |

| wendar | lifeless: got a second for fact-checking before I send some first drafts off to David Graves? | 19:49 |
| lifeless | of course | 19:49 |
| wendar | Generic statements about TripleO components. | 19:50 |
| wendar | Is it (at least abstractly) accurate to say that the Tuskar UI and APIs in the undercloud substitute for Horizon and related APIs in the overcloud? | 19:50 |
| wendar | or "serve the same functional purpose" | 19:51 |
| lifeless | tuskar UI *is* horizon | 19:52 |
| wendar | I know. | 19:52 |
| lifeless | but it doesn't substitute in any way, it complements | 19:52 |
| wendar | I'm trying to explain what Tuskar is. | 19:52 |
| wendar | i.e. Tuskar UI is an expanded version of Horizon | 19:52 |
| tzumainn | wendar, Tuskar exists to help create an overcloud deployment | 19:53 |
| lifeless | Tuskar (API) replaces the shell scripts we're using from the cnosole | 19:53 |
| lifeless | in principle anyhow | 19:53 |
| tzumainn | (sorry to jump in) | 19:53 |
| lifeless | it's an API for deploying a cloud using Heat. | 19:53 |
| lifeless | in the coarsest possible description | 19:53 |
| lifeless | tzumainn: jumping in is fine :) | 19:54 |
| openstackgerrit | A change was merged to openstack/tripleo-image-elements: Install syslinux also in nova-baremetal https://review.openstack.org/73623 | 19:54 |
| wendar | Perhaps it would be helpful to see the abstract diagram I modified. | 19:54 |
| tzumainn | lifeless, lol, okay | 19:54 |
| lifeless | wendar: diagrams would help; is it on the internal wiki somewhere? | 19:54 |
| wendar | tzumainn: always welcome to jump in :) | 19:54 |

| wendar | lifeless: would you put Tuskar as a separate component? | 20:02 |
| lifeless | no | 20:02 |
| wendar | i.e. integrated with Horizon in the undercloud? | 20:02 |

| Ng | derm | 20:03 |
| Ng | wow, I even mistyped derp | 20:03 |
| wendar | lifeless: hmmm... call Tuskar a "Horizon plugin for the undercloud"? | 20:04 |
| wendar | or simply an incubated addition to Horizon, planned to ultimately be integrated into the main Horizon? | 20:05 |

| hewbrocca | wendar: it's definitely a Horizon plugin | 20:19 |
| hewbrocca | Specifically, it provides a specialized user experience | 20:19 |
| wendar | lifeless: or, Tuskar is actually the deployment APIs, and the project is developing a plugin for Horizon to interface with the Tuskar APIs | 20:19 |
| hewbrocca | that is tailored to the creation and management of the Overcloud app | 20:19 |
| hewbrocca | this is Tuskar UI, specifically | 20:19 |
| hewbrocca | The main API the Tuskar UI calls is actually the Heat API | 20:20 |
| hewbrocca | Tuskar API itself is in flux as we determine how much of it we actually need | 20:20 |
| hewbrocca | jdob: ^^^ correct me if I'm wrong here... | 20:20 |
| wendar | I can also say that Tuskar effectively doesn't exist as a distinct component. | 20:20 |
| wendar | It is a UI plugin to Horizon, that interfaces with Heat APIs. | 20:20 |
| hewbrocca | That's probably the most accurate thing you can say | 20:21 |
| hewbrocca | We think there will be a place for Tuskar-specific API, but I don't think we're entirely sure yet | 20:21 |
| hewbrocca | certainly we will need a CLI that lets operators script overcloud management actions | 20:22 |
| dprince | pleia2: I think this should fix the Fedora ssh issue: https://review.openstack.org/#/c/74825/ | 20:23 |
| dprince | pleia2: I dev tested it locally and that covered the case where sshd was up... but the user had not yet been created | 20:23 |
| *** cadenzajon has quit IRC | 20:26 | |
| lifeless | sorry, ELOCAL | 20:26 |
| lifeless | cynthia now @ kindy :) | 20:26 |
| lifeless | wendar: ok so | 20:27 |
| lifeless | wendar: there are two bits to tuskar; a horizon plugin that extends horion in much the same way the nova console extends horizon - it lets you do 'tuskar' things with horizon | 20:28 |
| lifeless | wendar: but 'tuskar things' are 90% heat stack operations | 20:28 |
| lifeless | wendar: so ui is a plugin is the sum of it, adds calls to tuskar-api and some screens | 20:28 |
| lifeless | (and obviously calls to nova etc etc for the bits of tripleo that are using nova, neutron, whatnot. | 20:29 |
| wendar | lifeless: I guess the key distinction for my arch view is whether there is a running service somewhere in the system serving up tuskar-api responses that is distinct from Heat | 20:30 |
| lifeless | wendar: tuskar-api itself is a thin business layer that accentuates nova/neutron/heat/keystone | 20:30 |
| wendar | i.e. what kind of moving parts are we dealing with... | 20:30 |
| lifeless | wendar: there is today, its not clear that there needs to be | 20:30 |
| lifeless | wendar: which is what hewbrocca means by | 20:30 |
| lifeless | 09:20 < hewbrocca> Tuskar API itself is in flux as we determine how much of it we actually need | 20:30 |
| lifeless | wendar: so the second change I'd make in your diagram is to break out the 'BM's box | 20:31 |
| lifeless | because unlike VM's they aren't 'contained within' nova | 20:31 |
| wendar | lifeless: so currently (not necessarily in the future), in the undercloud, Horizon talks to a thin Tuskar API, as well as directly with nova, neutron, heat, etc? | 20:31 |
| lifeless | as you have Ironic there (which makes sense) I would create a stacked box, label it BM's, and an ownership arrow from Ironic to it. | 20:32 |
| lifeless | wendar: yes, and also to the APIs of the overcloud(s) | 20:32 |
| lifeless | wendar: well, i say that but really | 20:32 |
| lifeless | what we do is give the user a link to the horizon running in the overcloud | 20:32 |
| wendar | lifeless: yeah, it's a bit odd, since in overcloud it's really the KVM driver that "owns" the VMs, and Ironic is the bare metal equivalent to the KVM driver | 20:32 |
| lifeless | tuskar-API may end up doing some calls to the overcloud API during bringup | 20:33 |
| lifeless | the overcloud machines - all of them- also have an ongoing functional relationship with undercloud services: | 20:33 |
| lifeless | - neutron for DHCP | 20:33 |
| lifeless | - heat for configuration metadata | 20:33 |
| lifeless | - nova-api for bootstrap configuration | 20:33 |
| lifeless | I think that needs to be represented somehow | 20:34 |
| lifeless | perhaps the dotted line you have is sufficient | 20:34 |
| wendar | so, the overcloud and undercloud aren't running separate instances of those services? | 20:34 |
| lifeless | but maybe annotate it? | 20:34 |
| lifeless | they are separate | 20:34 |
| lifeless | but to boot a given overcloud service - say the overcloud horizon | 20:34 |
| lifeless | the machine it's own is powered on over IPMI by Ironic | 20:34 |
| lifeless | s/own/on/ | 20:34 |
| *** dprince has quit IRC | 20:35 | |
| lifeless | it DHCPs (served by undercloud neutron) | 20:35 |
| wendar | we'll have a much more heavily annotated digram later, with explicit relationships between each components | 20:35 |
| wendar | this is just a generic "overview" | 20:35 |
| lifeless | it makes EC2 metadata requests (served by undercloud nova API) | 20:35 |
| lifeless | it makes heat requests (served by undercloud heat API) | 20:35 |
| wendar | Ok, so the BM makes use of the undercloud versions of neutron, heat, and nova-api. | 20:35 |
| wendar | But, the VM in the overcloud doesn't? | 20:36 |
| lifeless | a VM deployed in the overcloud makes use of the matching services delivered by the overcloud | 20:36 |
| lifeless | e.g. it DHCPs off of Neutron | 20:36 |
| lifeless | (overcloud Neutron) | 20:36 |
| lifeless | what else | 20:37 |
| wendar | makes sense | 20:37 |
| lifeless | the uses-lines from from 'tuskar and apis' don't connect to ironic or swift, but this is probably incorrect | 20:37 |
| wendar | so, I think the abstraction is good enough for this diagram, but I'll make it more explicit in the full diagram | 20:37 |
| lifeless | Ironic is talked to to register machines | 20:37 |
| lifeless | swift would be talked to to check storage capacity (for images, but still) | 20:37 |
| wendar | oh, swift was a mistake | 20:37 |
| wendar | I was unsure about ironic | 20:38 |
| lifeless | how so ? | 20:38 |

| lifeless | oh, not linking it ? | 20:38 |
| wendar | I mean, I meant to connect swift. | 20:38 |
| lifeless | righto | 20:38 |
| wendar | but I wasn't sure about ironic | 20:38 |
| wendar | does horizon talk to it directly? | 20:38 |
| lifeless | reading the text now | 20:38 |
| wendar | or, only through Nova and Heat? | 20:38 |
| lifeless | I believe horizon has a swift module | 20:38 |
| wendar | yeah | 20:39 |
| lifeless | oh thats a potential source of confusion in your prose | 20:39 |
| wendar | I mean does horizon talk directly to ironic? | 20:39 |
| lifeless | there is no such thing as a Horizon API | 20:39 |
| lifeless | it will | 20:39 |
| wendar | ok | 20:39 |
| *** jcooley_ has joined #tripleo | 20:39 | |
| wendar | yes, I already edited out Horizon APIs from the new text | 20:39 |
| lifeless | ok | 20:39 |
| wendar | maybe I should just drop those boxes down to "Horizon"? | 20:39 |
| wendar | Aren't all the APIs provide by other components already in the diagram? | 20:40 |
| wendar | *provided | 20:40 |
| lifeless | right, all the components have APIs | 20:41 |
| lifeless | they also often have agents/engines separated out | 20:41 |
| lifeless | wendar: actually, I was referring to the text in your email in my 'source of confusion' reference - where you say 'though the APIs for Horizon vs Tuskar are different.' | 20:42 |
| wendar | lifeless: yeah deleted. | 20:42 |
| wendar | lifeless: is it more accurate to say "Horizon interfaces with different APIs in the overcloud and undercloud"? | 20:43 |
| wendar | well, some of the same apis, but some different | 20:43 |
| wendar | actually, the only thing different is the addition of Ironic APIs, and (for now) Tuskar APIs | 20:43 |
| lifeless | Yeah. Perhaps, for the avoidance of doubt, Each Horizon provides a GUI to use the APIs available in the matching cloud. | 20:43 |
| lifeless | wendar: and cinder | 20:43 |
| lifeless | wendar: possibly ceilometer etc; point is that all horizon is is a GUI - it doesn't add or delete capabilities or functionality, and it doesn't have privileged keys to access the APIs (AIUI) | 20:44 |
| lifeless | hewbrocca: ^ since you're around - sanity check me ? | 20:44 |
