    Functions

    func New

    func New(plArgs runtime.Object, handle framework.Handle) (framework.Plugin, error)

      New initializes a new plugin and returns it.

      Types

      type NodeLabel

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

        NodeLabel checks whether a pod can fit based on the node labels which match a filter that it requests.

        func (*NodeLabel) Filter

        func (pl *NodeLabel) Filter(ctx context.Context, _ *framework.CycleState, pod *v1.Pod, nodeInfo *framework.NodeInfo) *framework.Status

          Filter invoked at the filter extension point. It checks whether all of the specified labels exists on a node or not, regardless of their value

          Consider the cases where the nodes are placed in regions/zones/racks and these are identified by labels In some cases, it is required that only nodes that are part of ANY of the defined regions/zones/racks be selected

          Alternately, eliminating nodes that have a certain label, regardless of value, is also useful A node may have a label with "retiring" as key and the date as the value and it may be desirable to avoid scheduling new pods on this node.

          func (*NodeLabel) Name

          func (pl *NodeLabel) Name() string

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

            func (*NodeLabel) Score

            func (pl *NodeLabel) Score(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string) (int64, *framework.Status)

              Score invoked at the score extension point.

              func (*NodeLabel) ScoreExtensions

              func (pl *NodeLabel) ScoreExtensions() framework.ScoreExtensions

                ScoreExtensions of the Score plugin.
