Mickael Carl	2f35619710	discovery/kubernetes: attach node labels when the endpoints TargetRef's kind are Node Signed-off-by: Mickael Carl <mcarl@apple.com>	2 years ago
beorn7	c3c7d44d84	lint: Adjust to the lint warnings raised by current versions of golint-ci We haven't updated golint-ci in our CI yet, but this commit prepares for that. There are a lot of new warnings, and it is mostly because the "revive" linter got updated. I agree with most of the new warnings, mostly around not naming unused function parameters (although it is justified in some cases for documentation purposes – while things like mocks are a good example where not naming the parameter is clearer). I'm pretty upset about the "empty block" warning to include `for` loops. It's such a common pattern to do something in the head of the `for` loop and then have an empty block. There is still an open issue about this: https://github.com/mgechev/revive/issues/810 I have disabled "revive" altogether in files where empty blocks are used excessively, and I have made the effort to add individual `// nolint:revive` where empty blocks are used just once or twice. It's borderline noisy, though, but let's go with it for now. I should mention that none of the "empty block" warnings for `for` loop bodies were legitimate.

Julien Pivotto	3677d61a4b	Update kubernetes dependencies A new API is available for AddEventHandlers, to get errors but also be able to cancel handlers. Doing the easy thing for the release, which is just to log errors. We could see how to improve this in the future to handle the errors properly and cancel the handlers.

Robert Fratto	823d24d1e9	discovery/kubernetes: add container image as metadata This commits adds a __meta_kubernetes_pod_container_image as a new metadata label. This can be used to alert on mismatched versions of targets who don't have a build_info metric, as well as injecting it into log lines for other consumers of discovery/kubernetes (e.g., Promtail).

Filip Petkovski	05da373dcb	kubernetes_sd: Allow attaching node labels for endpoint role The Kubernetes service discovery can only add node labels to targets from the pod role. This commit extends this functionality to the endpoints and endpointslices roles. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	2 years ago

Yecheng Fu	8ceb8f2ae8	Refactor Kubernetes Discovery Part 2: Refactoring - Do initial listing and syncing to scrape manager, then register event handlers may lost events happening in listing and syncing (if it lasted a long time). We should register event handlers at the very begining, before processing just wait until informers synced (sync in informer will list all objects and call OnUpdate event handler). - Use a queue then we don't block event callbacks and an object will be processed only once if added multiple times before it being processed. - Fix bug in `serviceUpdate` in endpoints.go, we should build endpoints when `exists && err == nil`. Add `^TestEndpointsDiscoveryWithService` tests to test this feature. Testing: - Use `k8s.io/client-go` testing framework and fake implementations which are more robust and reliable for testing. - `Test\w+DiscoveryBeforeRun` are used to test objects created before discoverer runs - `Test\w+DiscoveryAdd\w+` are used to test adding objects - `Test\w+DiscoveryDelete\w+` are used to test deleting objects - `Test\w+DiscoveryUpdate\w+` are used to test updating objects - `TestEndpointsDiscoveryWithService\w+` are used to test endpoints events triggered by services - `cache.DeletedFinalStateUnknown` related stuffs are removed, because we don't care deleted objects in store, we only need its name to send a specical `targetgroup.Group` to scrape manager Signed-off-by: Yecheng Fu <cofyc.jackson@gmail.com>	7 years ago

pasquier-s	bde64cf5a6	Fix Kubernetes endpoints SD for empty subsets (#3660 ) * Fix Kubernetes endpoints SD for empty subsets When an endpoints object has no associated pods (replica scaled to zero for instance), the endpoints SD should return a target group with no targets so that the SD manager propagates this information to the scrape manager.
