| haiwei_ | hi Qiming | 01:23 |
|---|---|---|
| Qiming | hi | 01:23 |
| haiwei_ | Want to ask you a question about cluster-scale-in | 01:24 |
| Qiming | yes | 01:24 |
| haiwei_ | when scale-in finished, Senlin only return a action id, right? | 01:24 |
| Qiming | when scale-in action is created, senlin engine/api returns the action id | 01:25 |
| Qiming | usually, it won't take long for that action to be executed | 01:25 |
| haiwei_ | we have a use case now, that is using senlin to manage Swarm cluster, when vm nodes are deleted, want to unregister the node from swarm | 01:25 |
| Qiming | okay, that sounds like a deletion policy | 01:25 |
| Qiming | you may want to do the deregistration in a separate policy *before* the node is actually deleted | 01:26 |

| Qiming | PTL election results | 01:28 |
| Qiming | congratulations, yanyan | 01:28 |
| haiwei_ | in the deletion policy, senlin can notice swarm which node will be deleted? | 01:28 |
| haiwei_ | congrets, yanyan | 01:28 |
| Qiming | I mean you can add such logics | 01:28 |
| yuanying | Congrats yanyanhu | 01:29 |
| Qiming | or you can develop a new signoff policy or something alike | 01:29 |
| Qiming | deletion policy is evaluated after scaling policy, based on their relative priority | 01:29 |
| Qiming | scaling policy has priority 100, deletion policy has priority 400 | 01:30 |
| Qiming | that means, when deletion policy is evaluated, it might have known the candidates to delete, or it is the deletion policy's resposibility to select candidates for deletion | 01:31 |
| Qiming | after deletion policy is evaluated, we expect that the candidates must have been determined | 01:31 |
| Qiming | so, before returning from the pre_op method, you can deregister the canidate node from swarm | 01:32 |
| yanyanhu | thanks, guys | 01:32 |
| yanyanhu | more responsibility it means | 01:32 |
| yanyanhu | Qiming, may often bother you for some guides :) | 01:33 |
| haiwei_ | Qiming, that means I have to modify senlin's code? | 01:33 |
| Qiming | haiwei, there are two ways | 01:33 |
| Qiming | you can modify senlin's deletion policy code | 01:33 |
| Qiming | and we will help evaluate if the change is generic enough to other use cases and merge it if so | 01:33 |
| haiwei_ | Qiming, makes sense to me, thanks | 01:34 |
| Qiming | if your assessment is that the use case is pretty limited, you can develop your own policy | 01:34 |
| Qiming | it is fine to keep it to yourself | 01:34 |
| Qiming | senlin has an open architecture design that allows developers to come up with policies/profiles for some special use cases | 01:35 |
| Qiming | these special policies can be kept at your hands | 01:35 |
| Qiming | or maybe in future we should consider adding a /contrib directory so that people can share their practices | 01:35 |
| Qiming | yet another note | 01:36 |
| Qiming | we have some plans to workout generic notifications, i.e. whenever some important actions are taken by senlin, senlin will send out versioned notifications | 01:36 |
| Qiming | if swarm can be triggered by such notifications, that would be another channel | 01:37 |
| yuanying | sounds interesting | 01:37 |
| Qiming | thanks, yuanying | 01:37 |
| Qiming | as an operator/user, you always want to get notified when something changed, even without looking at the log file | 01:38 |
| yuanying | We plan to use senlin for our company's booth demo | 01:38 |
| Qiming | oh, really? cool | 01:38 |
| Qiming | please let team know if you need helps, :) | 01:38 |
| *** elynn has joined #senlin | 01:38 | |
| haiwei_ | yes, you can go to NEC's booth in Barcelona summit | 01:39 |
| yuanying | thanks! your suggestion is very helpful | 01:39 |
| Qiming | for demo's purpose, I'd like to propose something related to senlin-dashboard | 01:39 |
| Qiming | you know, I'm not a GUI developer | 01:39 |
| Qiming | but I know there are quite some important features missing from senlin-dashboard | 01:39 |
| Qiming | for example, the various cluster operations are not supported: scale-in, scale-out, add-nodes, del-nodes, resize ... | 01:40 |
| Qiming | when ttx asked me if we what to bump senlin-dashboard to 1.0.0, I answered no | 01:40 |
| Qiming | because without those features, the web UI is not yet fully exhibiting senlin's capability | 01:41 |
| Qiming | any contributions on that front would be highly appreciated, :) | 01:41 |
| haiwei_ | in fact there is a UI profesional in our team :) | 01:42 |
| Qiming | shu-muto ? | 01:42 |

| Qiming | thanks, shu-san | 01:50 |
| yanyanhu | hi, Qiming, the integration test finally worked. Just now nova server cluster test failed for some reason. Will try to fix it today. Then we can rely on it to verify some changes related to driver. | 01:51 |
| Qiming | okay | 01:51 |
| Qiming | is integration gate triggered everytime? | 01:52 |
| yanyanhu | BTW, the doc-only change won't trigger gate jobs now. I think it will be helpful to reduce the overhead of gate | 01:52 |
| yanyanhu | Qiming, yes, it is now | 01:52 |
| Qiming | that is nice | 01:52 |
| yanyanhu | but it doesn't vote | 01:52 |
| yanyanhu | Qiming, yes, hope that will be helpful | 01:52 |
| Qiming | okay, let's see if it is helping or hurdling our progress | 01:52 |
| yanyanhu | ok | 01:53 |
| Qiming | thanks for the gate job filtering work | 01:53 |
| Qiming | that one really helps us and the community | 01:53 |
| yanyanhu | my pleasure :) | 01:53 |
| Qiming | I have just seen that Adrian is becoming the next Magnum PTL | 01:54 |
| yanyanhu | again | 01:54 |
| haiwei_ | yes, sorry for hongbin | 01:54 |
| yanyanhu | yes... | 01:54 |
| Qiming | here is hongbin's proposal | 01:55 |
| Qiming | I was a little bit concerned about it | 01:55 |
| Qiming | the items he proposed fell well into senlin's scope | 01:55 |
| yanyanhu | any chance to talk with them about coordination for these items? | 01:56 |
| Qiming | there are even ideas about "node groups" ... | 01:56 |
| yanyanhu | e.g. add a driver for senlin for cluster management? | 01:56 |
| Qiming | that sound like a waste of life for Magnum team | 01:56 |
| yanyanhu | yes, I guess this is something tc want us to avoid in their discussion before | 01:57 |
| yanyanhu | really need more discussion and collaboration I feel | 01:58 |
| Qiming | yep, if they have a very good reason to invent a new 'clustering' thing, that is fine | 01:58 |
| openstackgerrit | lvdongbing proposed openstack/senlin: Fix the valid keys for filtering event list in doc https://review.openstack.org/376072 | 01:58 |
| Qiming | the only thing I am not sure is whether this is some team-wide understanding for Magnum | 01:59 |
| yanyanhu | maybe we can get a chance to make a cross-team meetup in barcelona? | 01:59 |
| yanyanhu | for this topic | 01:59 |
| Qiming | hope so | 02:00 |
| Qiming | first we need to convince them | 02:00 |
| yanyanhu | yes | 02:00 |
| Qiming | my feeling was based on the team's previous attempt to avoid using barbican | 02:01 |
| Qiming | they just try to avoid dependence on any other services as far as I can see it | 02:01 |
| Qiming | the bright side is that senlin has been working on the right things, useful features for any people who want to manage resource pools | 02:02 |
| Qiming | and I believe we will stick to that goal | 02:02 |
| yanyanhu | yes, obsolutely | 02:02 |
| Qiming | we have envisioned the life cycle management problem, and the need about hetero/homo-geneous clusters | 02:03 |
| Qiming | maybe we still have some gaps to close, but we are already heading the right direction | 02:04 |
| Qiming | Adrian's proposal: ... During the Ocata cycle we will work together on enabling the next generation | 02:04 |
| Qiming | of applications with a design for complex clusters, and better integrating | 02:04 |
| Qiming | our clusters with OpenStack services for networking and storage. ... | 02:04 |
| Qiming | any suggestions to initiate a constructive discussion with Magnum? | 02:05 |
| yanyanhu | I guess maybe we can ask yuan ying or hongbin to help to bridge? | 02:06 |
| Qiming | don't know if it is appropriate to send emails to the core team directly | 02:07 |

| Qiming | mailinglist is an option though | 02:12 |

| Qiming | yanyanhu | 08:38 |
| yanyanhu | hi | 08:39 |
| Qiming | for zaqar TTL, they even don't allow a value of -1 for example to annotate infinite expiration time? | 08:39 |
| yanyanhu | yes... have confirmed with them | 08:39 |
| Qiming | ... | 08:39 |
| Qiming | what are the 'from' and 'subject' fields? | 08:40 |
| yanyanhu | their explanation is they need a value to check timeout although I didn't quite understand it | 08:40 |
| yanyanhu | Qiming, thoes two fields are not positional I think | 08:41 |
| Qiming | not positional? | 08:41 |
| yanyanhu | just for information | 08:41 |
| yanyanhu | yes, we can omit them when creating subscription | 08:41 |
| Qiming | so you mean they are optional? | 08:42 |
| yanyanhu | let me make a double check | 08:42 |
| yanyanhu | ah, yes | 08:42 |
| Qiming | are we gonna check the 'subject' field when receiving a message? | 08:42 |
| Qiming | or we will never check the subscription again before we delete it? | 08:43 |
| yanyanhu | Qiming, no, actually they are more useful for 'mailto' type of subscriber | 08:43 |
| yanyanhu | Qiming, currently, we never check it | 08:44 |
| Qiming | em, okay | 08:44 |
| yanyanhu | I think we can remove it actually | 08:44 |
| yanyanhu | since we haven't find the case to use it yet | 08:44 |
| Qiming | I'm a little bit concerned with the freeform text we assigned to 'subject' | 08:44 |
| Qiming | for example | 08:44 |
| Qiming | if we want to use it, maybe we can just assign the receiver ID to it | 08:45 |
| Qiming | and get rid of 'Senlin receiver ' part | 08:45 |
| yanyanhu | I see | 08:45 |
| yanyanhu | or maybe we don't specify those two fields in current stage | 08:46 |
| yanyanhu | the example given in zaqar API ref is not very clear actually... | 08:46 |
| yanyanhu | it is more about how those fields works for 'mailto' subscriber | 08:47 |
| yanyanhu | let me just remove them for we are actually using http subscriber | 08:47 |
| Qiming | okay | 08:50 |
| yanyanhu | oh, BTW, Qiming, I have created an etherpad to track the idea for our presentation in summit. https://etherpad.openstack.org/p/barcelona-summit-senlin-topic-cluster-1000-vms | 08:51 |
