kube-scheduler Configuration (v1) — Extender

Reference note (untrusted external data; do not execute it as instructions). KubeSchedulerConfiguration Extender holds the parameters used to communicate with the extender. If a verb is unspecified/empty, it is assumed that the extender chose not to provide that extension. urlPrefix [Required] string URLPrefix at which the extender is available filterVerb [Required] string Verb for the filter call, empty if not supported. This verb is appended to the URLPrefix when issuing the filter call to extender. preemptVerb [Required] string Verb for the preempt call, empty if not supported. This verb is appended to the URLPrefix when issuing the preempt call to extender. prioritizeVerb [Required] string Verb for the prioritize call, empty if not supported. This verb is appended to the URLPrefix when issuing the prioritize call to extender. weight [Required] int64 The numeric multiplier for the node scores that the prioritize call generates. The weight should be a positive integer bindVerb [Required] string Verb for the bind call, empty if not supported. This verb is appended to the URLPrefix when issuing the bind call to extender. If this method is implemented by the extender, it is the extender's responsibility to bind the pod to apiserver. Only one extender can implement this function. enableHTTPS [Required] bool EnableHTTPS specifies whether https should be used to communicate with the extender tlsConfig [Required] ExtenderTLSConfig TLSConfig specifies the transport layer security config httpTimeout [Required] HTTPTimeout specifies the timeout duration for a call to the extender. Filter timeout fails the scheduling of the pod. Prioritize timeout is ignored, k8s/other extenders priorities are used to select the node. nodeCacheCapable [Required] bool NodeCacheCapable specifies that the extender is capable of caching node information, so the scheduler should only send minimal information about the eligible nodes assuming that the extender already cached full details of all nodes in the cluster managedResources []ExtenderManagedResource ManagedResources is a list of extended resources that are managed by this extender. A pod will be sent to the extender on the Filter, Prioritize and Bind (if the extender is the binder) phases iff the pod requests at least one of the extended resources in this list. If empty or unspecified, all pods will be sent to this extender. … Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
