## kube-scheduler
|
|
|
|
|
|
|
|
### Synopsis
|
|
|
|
|
|
The Kubernetes scheduler is a policy-rich, topology-aware,
|
|
workload-specific function that significantly impacts availability, performance,
|
|
and capacity. The scheduler needs to take into account individual and collective
|
|
resource requirements, quality of service requirements, hardware/software/policy
|
|
constraints, affinity and anti-affinity specifications, data locality, inter-workload
|
|
interference, deadlines, and so on. Workload-specific requirements will be exposed
|
|
through the API as necessary.
|
|

|
--google-json-key string The Google Cloud Platform Service Account JSON Key to use for authentication.
|
|
--kube-api-burst int32 Burst to use while talking with kubernetes apiserver (default 100)
|
|
--kube-api-content-type string Content type of requests sent to apiserver. (default "application/vnd.kubernetes.protobuf")
|
|
--kube-api-qps float32 QPS to use while talking with kubernetes apiserver (default 50)
|
|
--kubeconfig string Path to kubeconfig file with authorization and master location information.
|
|
--leader-elect Start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability.
|
|
--leader-elect-lease-duration duration 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. (default 15s)
|
|
--leader-elect-renew-deadline duration 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. (default 10s)

|
--leader-elect-resource-lock endpoints The type of resource object that is used for locking during leader election. Supported options are endpoints (default) and `configmaps`. (default "endpoints")
|
|
--leader-elect-retry-period duration The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled. (default 2s)
|
|
--lock-object-name string Define the name of the lock object. (default "kube-scheduler")
|
|
--lock-object-namespace string Define the namespace of the lock object. (default "kube-system")
|
|
--master string The address of the Kubernetes API server (overrides any value in kubeconfig)
|
|
--policy-config-file string File with scheduler policy configuration. This file is used if policy ConfigMap is not provided or --use-legacy-policy-config==true
|
|
--policy-configmap string Name of the ConfigMap object that contains scheduler's policy configuration. It must exist in the system namespace before scheduler initialization if --use-legacy-policy-config==false. The config must be provided as the value of an element in 'Data' map with the key='policy.cfg'
|
|
--policy-configmap-namespace string The namespace where policy ConfigMap is located. The system namespace will be used if this is not provided or is empty.
|
|
--port int32 The port that the scheduler's http service runs on (default 10251)
|
|
--profiling Enable profiling via web interface host:port/debug/pprof/
|
|
--scheduler-name string Name of the scheduler, used to select which pods will be processed by this scheduler, based on pod's "spec.SchedulerName". (default "default-scheduler")
|
|
--use-legacy-policy-config When set to true, scheduler will ignore policy ConfigMap and uses policy config file
|
|
--version version[=true] Print version information and quit
