Functions ¶

func Fits ¶ added in v1.18.0

func Fits(pod *v1.Pod, nodeInfo fwk.NodeInfo) bool

Fits checks if the pod has any ports conflicting with nodeInfo's ports. It returns true if there are no conflicts (which means that pod fits the node), otherwise false.

func New ¶

func New(_ context.Context, _ runtime.Object, _ fwk.Handle, fts feature.Features) (fwk.Plugin, error)

New initializes a new plugin and returns it.

Types ¶

type NodePorts ¶

type NodePorts struct {
	// contains filtered or unexported fields
}

NodePorts is a plugin that checks if a node has free ports for the requested pod ports.

func (*NodePorts) EventsToRegister ¶ added in v1.22.0

func (pl *NodePorts) EventsToRegister(_ context.Context) ([]fwk.ClusterEventWithHint, error)

EventsToRegister returns the possible events that may make a Pod failed by this plugin schedulable.

func (*NodePorts) Filter ¶

func (pl *NodePorts) Filter(ctx context.Context, cycleState fwk.CycleState, pod *v1.Pod, nodeInfo fwk.NodeInfo) *fwk.Status

Filter invoked at the filter extension point.

func (*NodePorts) Name ¶

func (pl *NodePorts) Name() string

Name returns name of the plugin. It is used in logs, etc.

func (*NodePorts) PreFilter ¶ added in v1.18.0

func (pl *NodePorts) PreFilter(ctx context.Context, cycleState fwk.CycleState, pod *v1.Pod, nodes []fwk.NodeInfo) (*fwk.PreFilterResult, *fwk.Status)

PreFilter invoked at the prefilter extension point.

func (*NodePorts) PreFilterExtensions ¶ added in v1.18.0

func (pl *NodePorts) PreFilterExtensions() fwk.PreFilterExtensions

PreFilterExtensions do not exist for this plugin.

func (*NodePorts) SignPod ¶

func (pl *NodePorts) SignPod(ctx context.Context, pod *v1.Pod) ([]fwk.SignFragment, *fwk.Status)
