kube-scheduler — Schedules containers on hosts.


kube-scheduler [Options]


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.

 -h, --help                                     help for kube-scheduler
     --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. (default true)
     --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")
     --log-flush-frequency duration             Maximum number of seconds between log flushes (default 5s)
     --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
  --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
