6 kube-scheduler - Schedules containers on hosts.

11 kube-scheduler [OPTIONS]
12
16 The Kubernetes scheduler is a policy-rich, topology-aware,
17 workload-specific function that significantly impacts availability,
18 performance, and capacity. The scheduler needs to take into account
19 individual and collective resource requirements, quality of service
20 requirements, hardware/software/policy constraints, affinity and
21 anti-affinity specifications, data locality, inter-workload
22 interference, deadlines, and so on. Workload-specific requirements will
23 be exposed through the API as necessary.

117 -h, --help help for kube-scheduler
121 --kube-api-burst int32 DEPRECATED
122 burst to use while talking with kubernetes apiserver (default 100)
123 --kube-api-content-type string DEPRECATED
126 content type of requests sent to apiserver. (default
127 "application/vnd.kubernetes.protobuf")
128 --kube-api-qps float32 DEPRECATED
131 QPS to use while talking with kubernetes apiserver (default 50)
132 --kubeconfig string DEPRECATED
135 path to kubeconfig file with authorization and master location
136 information.
137 --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)
140 --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)
141 --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)
142 --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")
143 --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)
144 --lock-object-name string DEPRECATED
148 define the name of the lock object. (default "kube-scheduler")
149 --lock-object-namespace string DEPRECATED
152 define the namespace of the lock object. (default "kube-system")
153 --log-flush-frequency duration Maximum number of seconds between log flushes (default 5s)

163 --policy-configmap string DEPRECATED
166 name of the ConfigMap object that contains scheduler's policy
167 configuration. It must exist in the system namespace before scheduler
168 initialization if --use-legacy-policy-config=false. The config must be
169 provided as the value of an element in 'Data' map with the
170 key='policy.cfg'
171 --policy-configmap-namespace string DEPRECATED
174 the namespace where policy ConfigMap is located. The kube-system
175 namespace will be used if this is not provided or is empty. (default
176 "kube-system")
177 --port int DEPRECATED
180 the port on which to serve HTTP insecurely without authentication
181 and authorization. If 0, don't serve HTTPS at all. See --secure-port
182 instead. (default 10251)
183 --profiling DEPRECATED
186 enable profiling via web interface host:port/debug/pprof/
187 --scheduler-name string DEPRECATED
190 name of the scheduler, used to select which pods will be processed
191 by this scheduler, based on pod's "spec.schedulerName". (default
192 "default-scheduler")
193 --use-legacy-policy-config DEPRECATED
196 when set to true, scheduler will ignore policy ConfigMap and uses
