Constants ¶

const Name = "multipoint-plugin-example"

Name is the name of the plug used in Registry and configurations.

Functions ¶

func New ¶

func New(ctx context.Context, config *runtime.Unknown, _ framework.Handle) (framework.Plugin, error)

New initializes a new plugin and returns it.

Types ¶

type MultipointExample ¶

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

MultipointExample is an example plugin that is executed at multiple extension points. This plugin is stateful. It receives arguments at initialization (NewMultipointPlugin) and changes its state when it is executed.

func (*MultipointExample) Name ¶

func (mp *MultipointExample) Name() string

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

func (*MultipointExample) PreBind ¶

func (mp *MultipointExample) PreBind(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string) *framework.Status

PreBind is the function invoked by the framework at "prebind" extension point.

func (*MultipointExample) Reserve ¶

func (mp *MultipointExample) Reserve(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string) *framework.Status

Reserve is the function invoked by the framework at "reserve" extension point. In this trivial example, the Reserve method allocates an array of strings.

func (*MultipointExample) Unreserve ¶

func (mp *MultipointExample) Unreserve(ctx context.Context, state *framework.CycleState, pod *v1.Pod, nodeName string)

Unreserve is the function invoked by the framework when any error happens during "reserve" extension point or later. In this example, the Unreserve method loses its reference to the string slice, allowing it to be garbage collected, and thereby "unallocating" the reserved resources.
