Functions

func NewHighNodeUtilization

func NewHighNodeUtilization(args runtime.Object, handle frameworktypes.Handle) (frameworktypes.Plugin, error)

NewHighNodeUtilization builds plugin from its arguments while passing a handle

func NewLowNodeUtilization

func NewLowNodeUtilization(args runtime.Object, handle frameworktypes.Handle) (frameworktypes.Plugin, error)

NewLowNodeUtilization builds plugin from its arguments while passing a handle

func RegisterDefaults

func RegisterDefaults(scheme *runtime.Scheme) error

RegisterDefaults adds defaulters functions to the given scheme. Public to allow building arbitrary schemes. All generated defaulters are covering - they call all nested defaulters.

func SetDefaults_HighNodeUtilizationArgs

func SetDefaults_HighNodeUtilizationArgs(obj runtime.Object)

SetDefaults_HighNodeUtilizationArgs TODO: the final default values would be discussed in community

func SetDefaults_LowNodeUtilizationArgs

func SetDefaults_LowNodeUtilizationArgs(obj runtime.Object)

SetDefaults_LowNodeUtilizationArgs TODO: the final default values would be discussed in community

func ValidateHighNodeUtilizationArgs

func ValidateHighNodeUtilizationArgs(obj runtime.Object) error

func ValidateLowNodeUtilizationArgs

func ValidateLowNodeUtilizationArgs(obj runtime.Object) error

Types
