Enable lock contention profiling, if profiling is enabled


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


A set of key=value pairs that describe feature gates for alpha/experimental features. Options are: Accelerators=true|false (ALPHA - default=false) AffinityInAnnotations=true|false (ALPHA - default=false) AllAlpha=true|false (ALPHA - default=false) AllowExtTrafficLocalEndpoints=true|false (BETA - default=true) AppArmor=true|false (BETA - default=true) DynamicKubeletConfig=true|false (ALPHA - default=false) DynamicVolumeProvisioning=true|false (ALPHA - default=true) ExperimentalCriticalPodAnnotation=true|false (ALPHA - default=false) ExperimentalHostUserNamespaceDefaulting=true|false (BETA - default=false) StreamingProxyRedirects=true|false (BETA - default=true) TaintBasedEvictions=true|false (ALPHA - default=false)


RequiredDuringScheduling affinity is not symmetric, but there is an implicit PreferredDuringScheduling affinity rule corresponding to every RequiredDuringScheduling affinity rule. --hard-pod-affinity-symmetric-weight represents the weight of implicit PreferredDuringScheduling affinity rule.


Burst to use while talking with kubernetes apiserver


Content type of requests sent to apiserver.


QPS to use while talking with kubernetes apiserver


Path to kubeconfig file with authorization and master location information.


Start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability.


The duration that non-leader candidates will wait after observing a leadership renewal until attempting to acquire leadership of a led but unrenewed leader slot. This is effectively the maximum duration that a leader can be stopped before it is replaced by another candidate. This is only applicable if leader election is enabled.


The interval between attempts by the acting master to renew a leadership slot before it stops leading. This must be less than or equal to the lease duration. This is only applicable if leader election is enabled.


The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled.


The address of the Kubernetes API server (overrides any value in kubeconfig)


File with scheduler policy configuration


The port that the scheduler's http service runs on


Enable profiling via web interface host:port/debug/pprof/


Name of the scheduler, used to select which pods will be processed by this scheduler, based on pod's "spec.SchedulerName".
