Types

type InsufficientResource

type InsufficientResource struct {
	ResourceName v1.ResourceName
	// We explicitly have a parameter for reason to avoid formatting a message on the fly
	// for common resources, which is expensive for cluster autoscaler simulations.
	Reason    string
	Requested int64
	Used      int64
	Capacity  int64
}

InsufficientResource describes what kind of resource limit is hit and caused the pod to not fit the node.

func Fits

func Fits(pod *v1.Pod, nodeInfo *schedulernodeinfo.NodeInfo, ignoredExtendedResources sets.String) []InsufficientResource

Fits checks if node have enough resources to host the pod.

type InsufficientResourceError

type InsufficientResourceError struct {
	ResourceName v1.ResourceName
	Requested    int64
	Used         int64
	Capacity     int64
}

InsufficientResourceError is an error type that indicates what kind of resource limit is hit and caused the unfitting failure.

func (*InsufficientResourceError) Error
