kube-scheduler — Schedules containers on hosts.

Synopsis

kube-scheduler [Options]

Description

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.

kube-scheduler

Options

--address string                           The IP address to serve on (set to 0.0.0.0 for all interfaces) (default "0.0.0.0")
--algorithm-provider string The scheduling algorithm provider to use, one of
ClusterAutoscalerProvider | DefaultProvider (default "DefaultProvider")
--azure-container-registry-config string   Path to the file container Azure container registry configuration information.
--failure-domains string                   Indicate the "all topologies" set for an empty topologyKey when it's used for PreferredDuringScheduling pod anti-affinity. (default "kubernetes.io/hostname,failure-domain.beta.kubernetes.io/zone,failure-domain.beta.kubernetes.io/region")
--feature-gates mapStringBool A set of key=value pairs that describe feature gates for alpha/experimental features. Options are
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) ExperimentalHostUserNamespaceDefaulting=true|false (ALPHA - default=false) StreamingProxyRedirects=true|false (ALPHA - default=false)
--google-json-key string The Google Cloud Platform Service Account JSON Key to use for authentication.
--hard-pod-affinity-symmetric-weight int 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. (default 1)
--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-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)
--master string The address of the Kubernetes API server (overrides any value in kubeconfig)
--policy-config-file string File with scheduler policy configuration
--port int32 The port that the scheduler's http service runs on (default 10251) --profiling Enable profiling via web interface host
port/debug/pprof/ (default true)
--scheduler-name string                    Name of the scheduler, used to select which pods will be processed by this scheduler, based on pod's annotation with key 'scheduler.alpha.kubernetes.io/name' (default "default-scheduler")
