Types

type AdmissionPluginArg

type AdmissionPluginArg string

AdmissionPluginArg represents a command line argument to the VPA's recommender that may be combined with a value or numerical range.

func (AdmissionPluginArg) String

func (a AdmissionPluginArg) String() string

String returns the argument as a plain string.

func (AdmissionPluginArg) Value

func (a AdmissionPluginArg) Value(v interface{}) string

Value returns the argument with the given value set.

type Config

type Config struct {
	// The release version assigned to the operator config.
	ReleaseVersion string
	// The name of the singleton VerticalPodAutoscalerController resource.
	Name string
	// The namespace for vertical-pod-autoscaler deployments.
	Namespace string
	// The vertical-pod-autoscaler image to use in deployments.
	Image string
	// The log verbosity level for the vertical-pod-autoscaler.
	Verbosity int
	// Additional arguments passed to the vertical-pod-autoscaler.
	ExtraArgs string
}

Config represents the configuration for a reconciler instance.

type RecommenderArg

type RecommenderArg string

RecommenderArg represents a command line argument to the VPA's recommender that may be combined with a value or numerical range.

const (
	LogToStderrArg          RecommenderArg = "--logtostderr"
	VerbosityArg            RecommenderArg = "--v"
	SafetyMarginFractionArg RecommenderArg = "--recommendation-margin-fraction"
	PodMinCPUMillicoresArg  RecommenderArg = "--pod-recommendation-min-cpu-millicores"
	PodMinMemoryMbArg       RecommenderArg = "--pod-recommendation-min-memory-mb"
)

These constants represent the vertical-pod-autoscaler arguments used by the operator when processing VerticalPodAutoscalerController resources.

func (RecommenderArg) String

func (a RecommenderArg) String() string

String returns the argument as a plain string.

func (RecommenderArg) Value

func (a RecommenderArg) Value(v interface{}) string

Value returns the argument with the given value set.

type Reconciler

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

Reconciler reconciles a VerticalPodAutoscalerController object
