vikasc | irenab, ping | 05:10 |
irenab | vikasc: hi | 05:10 |
vikasc | irenab, your point makes sense to me. | 05:11 |
irenab | vikasc: regarding REST vs RPC? | 05:11 |
vikasc | irenab, yes | 05:11 |
vikasc | irenab, having it configurable | 05:11 |
*** shashank_hegde has joined #openstack-kuryr | 05:12 | |
vikasc | irenab, i am thinking of keeping original controllers.py with rest calls as it is | 05:12 |
vikasc | irenab, and renaming rpc controller.py to something like cotroller_rpc.py | 05:12 |
irenab | vikasc: alternatively, you can have driver layer for the Controller | 05:12 |
irenab | since most of the code would be generic, and only the way to call neutron will differ | 05:13 |
vikasc | irenab, do you mean like having fucntions like 'create_neutron_network' etc in kuryr/lib | 05:14 |
vikasc | irenab, and then based on configuration framing the rpc call or neutron call | 05:15 |
vikasc | irenab, in the function definition? | 05:15 |
vikasc | adding these wrapper functions in kuryr/lib/utils | 05:16 |
vikasc | irenab, kuryr/lib/utils.py i mean | 05:16 |
irenab | the analogy would be the neutron services plugins that have drivers that you specify in config file | 05:16 |
irenab | driver has base API implemented acccordingly (REST calls/ RPC calls) | 05:17 |
vikasc | irenab, means all these methods like "create_neutron_network" will be defined in each driver file | 05:18 |
*** limao_ has joined #openstack-kuryr | 05:19 | |
vikasc | irenab, and from controllers.py will be invoked as app.driver.create_neutron_network | 05:19 |
irenab | yes | 05:19 |
irenab | you basically has base driver that defines methods and specific one that implement them | 05:20 |
vikasc | irenab, thanks , will go through neutron service plugins also for reference. | 05:20 |
vikasc | irenab, understood | 05:20 |
vikasc | irenab, importing the base driver | 05:20 |
irenab | vikasc: check this one: https://github.com/openstack/neutron/blob/master/neutron/services/qos/qos_plugin.py | 05:21 |
vikasc | irenab, i think i understood your idea | 05:21 |
vikasc | irenab, thanks a lot for guidance | 05:22 |
*** limao has quit IRC | 05:22 | |
vikasc | irenab, one more doubt | 05:22 |
vikasc | irenab, to be honest i could not understand absoulte clearly why in case of vms we want rpc | 05:23 |
vikasc | irenab, when i asked in meeting i got impression that everybody is certain that rpc is needed but due to lack of time i could not ask in detail. | 05:24 |
vikasc | irenab, i decided to understand in future real pros of having rpc with vms | 05:24 |
irenab | vikasc: I need to revisit the nested spec to make sure I remember the details. Lets try to chat about it here a bit later once apuimedo is online. I think its was about security and credentials distribution and related to Magnum being deploying the cluster | 05:25 |
vikasc | irenab, sure. will keep looking for apuimedo | 05:26 |
irenab | for Bare Metal I would love to hear banix, I think RPC is not required | 05:26 |
vikasc | irenab, i am not able to clearly understand why rpc is needed even in vms case :D | 05:27 |
vikasc | irenab, credentials anyways we have to store at vms to create rpc context | 05:28 |
irenab | vikasc: but I think its not keystone | 05:28 |
vikasc | irenab, keystone admin endpoint we will be able to skip with implementing rpc | 05:29 |
vikasc | irenab, i just want to confirm is this the only purpose of rpc | 05:29 |
irenab | vikasc: exactly, I agree | 05:29 |
vikasc | irenab, otherwise we can move all neutron calling functionality to common kuryr/lib/utils.py | 05:30 |
vikasc | irenab, with a little bit refactoring | 05:30 |
vikasc | irenab, and then all k8s or any other coe can reuse it | 05:30 |
*** limao_ has quit IRC | 05:32 | |
irenab | vikasc: this can be great, and I think we can do it anyway regardless split to drivers | 05:32 |
*** limao has joined #openstack-kuryr | 05:32 | |
irenab | to avoid code duplication | 05:33 |
vikasc | irenab, will be doing it this way only even with drivers | 05:33 |
vikasc | irenab, i mean agree.. will be doing it in any case | 05:33 |
vikasc | irenab, but if rpc is used functionality of these methods will be there in handlers on kuryr rpc server | 05:34 |
*** obondarev has joined #openstack-kuryr | 05:35 | |
vikasc | irenab, if we do rpc and decide to call neutron rest apis in case of baremetal as you suggested, then in that case methods from kuryr/lib/utils.py will be used | 05:36 |
vikasc | irenab, ahh.. sorry rpc_handlers can also use the same util methods | 05:37 |
vikasc | irenab, in all cases, its making sense to keep these at kuryr/lib/utils | 05:38 |
irenab | vikasc: or maybe kuryr/lib/drivers | 05:40 |
vikasc | irenab, even if we decide not to use rpc? | 05:41 |
irenab | but in general I like the direction. There is nothing COE specific, so makes sense to keep in in kuryr/lib | 05:41 |
irenab | vikasc: utils makes more sense to have more auxiliry methods. ‘drivers’ maybe named better :-) | 05:42 |
vikasc | irenab, i mean introducing "drivers" term, even in case if decide not tu use rpc | 05:42 |
vikasc | irenab, ? | 05:43 |
vikasc | irenab, i think are almost on the same page now | 05:44 |
vikasc | irenab, :) | 05:44 |
irenab | vikasc: named not drivers, but something like ‘neutron’ … Not sure | 05:44 |
*** obondarev has quit IRC | 05:44 | |
vikasc | irenab, next is to discuss pros of rpc | 05:44 |
irenab | vikasc: great. Maybe worth to have it on email thread | 05:45 |
vikasc | irenab, lets discuss with apuimedo atleat first | 05:46 |
irenab | vikasc: sounds like a plan | 05:46 |
vikasc | irenab, plan? sorry i did not get you :) | 05:47 |
vikasc | irenab, it takes a lot of time to get reply on ml :P | 05:48 |
irenab | I mean, sounds great. Lets do it | 05:48 |
vikasc | irenab, thanks | 05:48 |
irenab | first discuss with apuimedo and then see if need to communicate more over email | 05:48 |
irenab | or just follow up with the patch | 05:49 |
vikasc | irenab, exactly .. bye till we have apuimedo on irc | 05:49 |
irenab | vikasc: have a great day | 05:49 |

apuimedo | ping neiljerram | 10:28 |
apuimedo | vikasc: hey | 10:28 |
apuimedo | Sorry I didn't see it untiil a bit late :/ | 10:28 |
vikasc | apuimedo, hi | 10:28 |
vikasc | apuimedo, np | 10:28 |
apuimedo | glad you are still around! | 10:28 |
vikasc | :) | 10:29 |
apuimedo | I thought I may have missed you | 10:29 |
vikasc | apuimedo, lets see if irenab is also around | 10:29 |
neiljerram | apuimedo, hi | 10:29 |
vikasc | apuimedo, on my rpc support patch she raised a concern that why we need rpc | 10:30 |
irenab | vikasc: it was more about replacment of the REST API versus have two drivers to choose based on deployment option | 10:30 |
vikasc | apuimedo, only pros which i could share to her was that keystone and neutron endpoints can be avoided on vms | 10:31 |
apuimedo | from where I stand | 10:31 |
apuimedo | I would only use RPC in the nested case | 10:32 |
vikasc | apuimedo, can you please share reasons for your preference | 10:32 |
apuimedo | vikasc: I think on non-nested case adding another level of indirection would introduce too much latency | 10:34 |
vikasc | apuimedo, skipping service endpoints is the one | 10:34 |
vikasc | apuimedo, agree | 10:34 |
vikasc | apuimedo, on that part i agree that introducing a driver layer makes sense | 10:35 |
vikasc | irenab, ping | 10:35 |
apuimedo | so, for me, I'd have kuryr-common to have an optional rpc server | 10:36 |
vikasc | apuimedo, was wondering about pros of using rpc instead of calling neutron rest api directly | 10:36 |
apuimedo | that's a good question | 10:37 |
apuimedo | I would make the RPC probably use a different auth | 10:37 |
vikasc | apuimedo, means other than keystone | 10:38 |
vikasc | apuimedo, ? | 10:38 |
apuimedo | yes, I was thinking that it could just be an ssl connection between VM and kuryr server | 10:39 |
irenab | vikasc: sorry in the meeting. Will check the log in 40 mins | 10:40 |
vikasc | irenab, sure | 10:40 |
vikasc | apuimedo, and how certificates will be exchanged? | 10:41 |
vikasc | and stored? | 10:41 |
vikasc | apuimedo, can you please give some reference example? | 10:42 |
vikasc | apuimedo, is it like using barbican | 10:43 |
vikasc | apuimedo, do you mean like this, https://github.com/openstack/magnum/blob/master/specs/tls-support-magnum.rst | 10:44 |
vikasc | apuimedo, tls support | 10:45 |
apuimedo | I would need to talk with Magnum people about that :P | 10:45 |
apuimedo | I haven't really gone into detail | 10:45 |
apuimedo | but I guess that hongbin would be able to tell us | 10:45 |
vikasc | apuimedo, okay on high level its all about security | 10:45 |
vikasc | apuimedo, right? | 10:46 |
vikasc | apuimedo, aim is to try to avoid user credentials and endpoints on vms | 10:46 |
apuimedo | right | 10:48 |
vikasc | apuimedo, rpc support is working at the moment and has been pushed for review on both repos | 10:49 |
apuimedo | vikasc: I'll take a look this week | 10:50 |
apuimedo | I still don't know exactly when | 10:50 |
vikasc | apuimedo, what is your opinion on introducing a driver layer as Irena and I discussed? | 10:50 |
apuimedo | where can I read more about it? | 10:50 |
vikasc | apuimedo, and what is the plan to accept patches in kuryr repo | 10:50 |
vikasc | apuimedo, at the moment requirements is being met from my github repo | 10:51 |
apuimedo | vikasc: I'd like to be able to make a kuryr release by the end of next week | 10:51 |
vikasc | apuimedo, i have to sync the patches in kuryr repo with my account each time i make a change | 10:51 |
apuimedo | which should unblock us in kuryr-libnetwork | 10:52 |
apuimedo | sorry about that :( | 10:52 |
vikasc | apuimedo, no problem. Request you to just review kuryr repo patches | 10:53 |
apuimedo | vikasc: will do! | 10:53 |
apuimedo | thanks! | 10:53 |
vikasc | apuimedo, thanks !! | 10:53 |
