5.17. Kubernetes Scheduler Operator
Purpose

The Kubernetes Scheduler Operator contains the following components:
- Operator
- Bootstrap manifest renderer
- Installer based on static pods
- Configuration observer
By default, the Operator exposes Prometheus metrics through the metrics service.

Configuration
The configuration for the Kubernetes Scheduler is the result of merging:
- a default configuration.
-
an observed configuration from the spec
schedulers.config.openshift.io.
All of these are sparse configurations, invalidated JSON snippets which are merged in order to form a valid configuration at the end.
