Types

type KubeSchedulerConfiguration

type KubeSchedulerConfiguration struct {
	metav1.TypeMeta

	// SchedulerName is name of the scheduler, used to select which pods
	// will be processed by this scheduler, based on pod's "spec.SchedulerName".
	SchedulerName string
	// AlgorithmSource specifies the scheduler algorithm source.
	AlgorithmSource SchedulerAlgorithmSource
	// RequiredDuringScheduling affinity is not symmetric, but there is an implicit PreferredDuringScheduling affinity rule
	// corresponding to every RequiredDuringScheduling affinity rule.
	// HardPodAffinitySymmetricWeight represents the weight of implicit PreferredDuringScheduling affinity rule, in the range 0-100.
	HardPodAffinitySymmetricWeight int32

	// LeaderElection defines the configuration of leader election client.
	LeaderElection KubeSchedulerLeaderElectionConfiguration

	// ClientConnection specifies the kubeconfig file and client connection
	// settings for the proxy server to use when communicating with the apiserver.
	ClientConnection apimachineryconfig.ClientConnectionConfiguration
	// HealthzBindAddress is the IP address and port for the health check server to serve on,
	// defaulting to 0.0.0.0:10251
	HealthzBindAddress string
	// MetricsBindAddress is the IP address and port for the metrics server to
	// serve on, defaulting to 0.0.0.0:10251.
	MetricsBindAddress string

	// DebuggingConfiguration holds configuration for Debugging related features
	// TODO: We might wanna make this a substruct like Debugging apiserverconfig.DebuggingConfiguration
	apiserverconfig.DebuggingConfiguration

	// DisablePreemption disables the pod preemption feature.
	DisablePreemption bool

	// PercentageOfNodeToScore 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 (50%) of the nodes will be scored.
	PercentageOfNodesToScore int32

	// DEPRECATED.
	// Indicate the "all topologies" set for empty topologyKey when it's used for PreferredDuringScheduling pod anti-affinity.
	FailureDomains string

	// Duration to wait for a binding operation to complete before timing out
	// Value must be non-negative integer. The value zero indicates no waiting.
	// If this value is nil, the default value will be used.
	BindTimeoutSeconds *int64
