KubeSchedulerConfiguration configures a scheduler apiVersionstringkubescheduler.config.k8s.io/v1 kindstringKubeSchedulerConfiguration parallelism [Required] int32 Parallelism defines the amount of parallelism in algorithms for scheduling a Pods. Must be greater than 0. Defaults to 16 leaderElection [Required] LeaderElectionConfiguration LeaderElection defines the configuration of leader election client. clientConnection [Required] ClientConnectionConfiguration ClientConnection specifies the kubeconfig file and client connection settings for the proxy server to use when communicating with the apiserver. DebuggingConfiguration [Required] DebuggingConfiguration (Members of DebuggingConfiguration are embedded into this type.) DebuggingConfiguration holds configuration for Debugging related features TODO: We might wanna make this a substruct like Debugging componentbaseconfigv1alpha1.DebuggingConfiguration percentageOfNodesToScore [Required] int32 PercentageOfNodesToScore is the percentage of all nodes that once found feasible for running a pod, the scheduler stops its search for more feasible nodes in the cluster. This helps improve scheduler's performance. Scheduler always tries to find at least "minFeasibleNodesToFind" feasible nodes no matter what the value of this flag is. Example: if the cluster size is 500 nodes and the value of this flag is 30, then scheduler stops finding further feasible nodes once it finds 150 feasible ones. When the value is 0, default percentage (5%--50% based on the size of the cluster) of the nodes will be scored. It is overridden by profile level PercentageOfNodesToScore. podInitialBackoffSeconds [Required] int64 PodInitialBackoffSeconds is the initial backoff for unschedulable pods. If specified, it must be greater than 0. If this value is null, the default value (1s) will be used. podMaxBackoffSeconds [Required] int64 PodMaxBackoffSeconds is the max backoff for unschedulable pods. If specified, it must be greater than podInitialBackoffSeconds. If this value is null, the default value (10s) will be used. profiles [Required] []KubeSchedulerProfile Profiles are scheduling profiles that kube-scheduler supports. Pods can choose to be scheduled under a particular profile by setting its associated scheduler name. … Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
