Types ¶

type Config ¶

type Config struct {
	// WatchNamespace is the namespace the operator will watch for
	// ClusterAutoscaler and MachineAutoscaler instances.
	WatchNamespace string

	// ClusterAutoscalerNamespace is the namespace in which
	// cluster-autoscaler deployments will be created.
	ClusterAutoscalerNamespace string

	// ClusterAutoscalerName is the name of the ClusterAutoscaler
	// resource that will be watched by the operator.
	ClusterAutoscalerName string

	// ClusterAutoscalerImage is the image to be used in
	// ClusterAutoscaler deployments.
	ClusterAutoscalerImage string

	// ClusterAutoscalerReplicas is the number of replicas to be
	// configured in ClusterAutoscaler deployments.
