The test ``` [PositiveFlow] Deployer execution with a running cluster without any components when deployed with resource-topology-exporter as the updater [It] should verify a test pod scheduled with the topology aware scheduler goes running ``` started to flake lately with the symptoms matching a timeout due to slow CI. Relax the timeout and add more logs to (try to) deflake the issue. Signed-off-by: Francesco Romani <[email protected]>
Add support to gather and set cache fine-tuning parameters: ForeignPodsDetectMode and CacheResyncMethod, both exposed in the `cache` subfield of the plugin parameters (at least cacheResyncPeriodSeconds also belong there, but this is another story for another day). Also add validation support for the parameters. Signed-off-by: Francesco Romani <[email protected]>
The scheduler plugin gained support for the external informer, necessary to overcome mismatch between the scheduler and the ode views wrt the pods on nodes. Expose support in the deployer libraries to change this setting. Signed-off-by: Francesco Romani <[email protected]>
