Functions

func IsNodeUnschedulable

func IsNodeUnschedulable(node *v1.Node) bool

IsNodeUnschedulable checks if the node is unschedulable. This is a helper function to check only in case of underutilized node so that they won't be accounted for.

func IsReady

func IsReady(node *v1.Node) bool

IsReady checks if the descheduler could run against given node.

func PodFitsAnyNode

func PodFitsAnyNode(pod *v1.Pod, nodes []*v1.Node) bool

PodFitsAnyNode checks if the given pod fits any of the given nodes, based on multiple criteria, like, pod node selector matching the node label, node being schedulable or not.

func PodFitsAnyOtherNode

func PodFitsAnyOtherNode(pod *v1.Pod, nodes []*v1.Node) bool

PodFitsAnyOtherNode checks if the given pod fits any of the given nodes, besides the node the pod is already running on. The node fit is based on multiple criteria, like, pod node selector matching the node label (including affinity), the taints on the node, and the node being schedulable or not.

func PodFitsCurrentNode

func PodFitsCurrentNode(pod *v1.Pod, node *v1.Node) bool

PodFitsCurrentNode checks if the given pod fits on the given node if the pod node selector matches the node label.

func ReadyNodes

func ReadyNodes(ctx context.Context, client clientset.Interface, nodeInformer coreinformers.NodeInformer, nodeSelector string) ([]*v1.Node, error)

ReadyNodes returns ready nodes irrespective of whether they are schedulable or not.
