func ScaleDownArgs(sd *v1alpha1.ScaleDownConfig) []string

ScaleDownArgs returns a slice of strings representing command line arguments to the cluster-autoscaler corresponding to the values in the given ScaleDownConfig object.

Types

type AutoscalerArg

type AutoscalerArg string

AutoscalerArg represents a command line argument to the cluster-autoscaler that may be combined with a value or numerical range.

const (
	LogToStderrArg                  AutoscalerArg = "--logtostderr"
	NamespaceArg                    AutoscalerArg = "--namespace"
	CloudProviderArg                AutoscalerArg = "--cloud-provider"
	MaxGracefulTerminationSecArg    AutoscalerArg = "--max-graceful-termination-sec"

	GPUTotalArg                     AutoscalerArg = "--gpu-total"
)

These constants represent the cluster-autoscaler arguments used by the operator when processing ClusterAutoscaler resources.

func (AutoscalerArg) Range

func (a AutoscalerArg) Range(min, max int) string

Range returns the argument with the given numerical range set.

func (AutoscalerArg) String

func (a AutoscalerArg) String() string

String returns the argument as a plain string.

func (AutoscalerArg) TypeRange

func (a AutoscalerArg) TypeRange(t string, min, max int) string

TypeRange returns the argument with the given type and numerical range set.

func (AutoscalerArg) Value

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

Value returns the argument with the given value set.

type Config

type Config struct {
	// The name of the singleton ClusterAutoscaler resource.
	Name string
	// The namespace for cluster-autoscaler deployments.
	Namespace string
	// The cluster-autoscaler image to use in deployments.
	Image string
	// The number of replicas in cluster-autoscaler deployments.
	Replicas int32
}

Config represents the configuration for a reconciler instance.

type Reconciler

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

Reconciler reconciles a ClusterAutoscaler object

func NewReconciler

func NewReconciler(mgr manager.Manager, cfg *Config) *Reconciler

NewReconciler returns a new Reconciler.

func (*Reconciler) AddToManager

func (r *Reconciler) AddToManager(mgr manager.Manager) error

AddToManager adds a new Controller to mgr with r as the reconcile.Reconciler

func (*Reconciler) AutoscalerDeployment

func (r *Reconciler) AutoscalerDeployment(ca *autoscalingv1alpha1.ClusterAutoscaler) *appsv1.Deployment

AutoscalerDeployment returns the expected deployment belonging to the given ClusterAutoscaler.

func (*Reconciler) AutoscalerName
