Hui Wang 4e3242b02d lib/promscrape/discovery/kubernetes: fix watcher start order for roles endpoints and endpointslice (#5557) ... * lib/promscrape/discovery/kubernetes: fix watcher start order for roles endpoints and endpointslice Previously the groupWatcher could be mistakenly stopped when requests for pod or services resources take too long. * remove mislead comment * docs/sd_configs.md: mention -promscrape.kubernetes.attachNodeMetadataAll flag in the description for attach_metadata section Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4640 * wip * lib/promscrape/kubernetes: prevent from stopping groupWatcher when there are in-flight apiWatcher.mustStart() calls groupWatcher is stopped if it has zero registered apiWatchers during 14 seconds. But such a groupWatcher can be still in use if apiWatcher for `role: endpoints` or `role: endpointslice` is being registered and the discovery of the associated `pod` and/or `service` objects takes longer than 14 seconds - see the beginning of groupWatcher.startWatchersForRole() function for details. Track the number of in-flight calls to apiWatcher.mustStart() and prevent from stopping the associated groupWatcher if the number of in-flight calls is non-zero. P.S. postponing the discovery of `pod` and/or `service` objects associated with `endpoints` or `endpointslice` roles isn't the best solution, since it slows down initial discovery of `endpoints` and `endpointslice` targets. * typo fix --------- Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>		2024-01-21 23:13:15 +02:00
