| *** yamamoto has joined #openstack-kuryr | 09:12 | |
| apuimedo | dulek: I do now | 09:47 |
| apuimedo | sorry for the delay | 09:47 |
| dulek | apuimedo: No problem. I'll briefly explain what I've did yesterday, so we can discuss that at the call. | 09:48 |
| apuimedo | ok | 09:48 |
| dulek | apuimedo: I've switched the daemon to cotyledon and flask (first choice, I can switch that if we have anyone who has preference). | 09:48 |
| *** yamamoto has quit IRC | 09:49 | |
| apuimedo | how does it behave? | 09:49 |
| dulek | apuimedo: At least it works. :D | 09:49 |
| dulek | apuimedo: Fun part with pooled watcher is that I've started to get WATCH events *before* I've got CNI requests. | 09:49 |
| apuimedo | :-) | 09:49 |
| dulek | apuimedo: So I've rewritten the watcher to put (pod, vif) pairs into a registry. | 09:50 |
| dulek | apuimedo: And CNI daemon looks into the registry, waits a bit if pod isn't yet there, but once it is - all connecting is performed. | 09:50 |
| dulek | apuimedo: So currently it looks like that: I have 2 cotyledon services, one for watcher and one for HTTP server. | 09:51 |
| dulek | apuimedo: (cotyledon.service = process) | 09:51 |
| apuimedo | right | 09:51 |
| dulek | apuimedo: Those are connected through multiprocessing.Queue, so watcher can send (pod, vif) to the registry on the server side. | 09:51 |
| dulek | apuimedo: And server does what I've already explained - looks into the registry, waits a bit if pod isn't there yet. | 09:52 |
| dulek | How does it sound to you from the design perspective? | 09:52 |
| apuimedo | so the watcher is watching on the host selector already? | 09:52 |
| dulek | apuimedo: Yup! | 09:52 |
| apuimedo | that's awesome | 09:53 |
| apuimedo | and on terminating we don't need to wait because we already have it in the registry | 09:53 |
| apuimedo | correct? | 09:53 |
| dulek | apuimedo: I think I can imagine corner cases. | 09:53 |
| dulek | apuimedo: But 99.99% of the time pod should be there. | 09:54 |
| dulek | apuimedo: To fight the problem of pods being deleted before kuryr wires them, I think I can watch on_delete as well and update registry with some sentinel. | 09:55 |
| apuimedo | well, the corner case | 09:55 |
| apuimedo | is only that we terminate before we bind | 09:56 |
| apuimedo | and in that case, I think that what we should so is just cancel the "wait for a bit when adding to network" | 09:56 |
| apuimedo | right | 09:56 |
| apuimedo | the http server works in threads I suppose | 09:57 |
| apuimedo | right? | 09:57 |
| dulek | Watcher is a child process, HTTP server is another child process with threads for: 1. reading from multiprocessing.Queue; 2. serving requests. | 09:58 |
| dulek | apuimedo: Another corner case - I can imagine HTTP process dying (e.g. OOM), so in-memory registry is lost. Then it's being restarted by cotyledon, but has no registry. | 09:58 |
| dulek | apuimedo: We should probably make watcher reissue whole GET from time to time. | 09:59 |
| apuimedo | dulek: should we mmap that maybe? | 09:59 |
| apuimedo | or just somehow request a refresh? | 09:59 |
| dulek | apuimedo: mmap sounds like a hammer solution. Not that I don't like it. ;) | 10:00 |
| apuimedo | :-) | 10:00 |
| *** yboaron_ has joined #openstack-kuryr | 10:00 | |
| dulek | apuimedo: If we could hare parent process memory with children, that would be best probably. | 10:01 |

| apuimedo | bluejeans is loading ultra slow for me | 10:01 |
| dulek | apuimedo: As watcher only writes, http server only reads, we should be safe. | 10:01 |
| apuimedo | right | 10:02 |
| dulek | apuimedo: Works for me. | 10:02 |
| apuimedo | I'll kill -9 it | 10:02 |
| apuimedo | and try again | 10:02 |
