Overview ¶
Package v1alpha1 is the v1alpha1 version of the API. +k8s:deepcopy-gen=package,register +k8s:openapi-gen=true +groupName=autoscaling.karmada.io
Index ¶
Constants ¶
const GroupName = "autoscaling.karmada.io"
GroupName specifies the group name used to register the objects.
Variables ¶
var ( // localSchemeBuilder and AddToScheme will stay in k8s.io/kubernetes. SchemeBuilder runtime.SchemeBuilder // Depreciated: use Install instead AddToScheme = localSchemeBuilder.AddToScheme Install = localSchemeBuilder.AddToScheme )
var GroupVersion = v1.GroupVersion{Group: GroupName, Version: "v1alpha1"}
GroupVersion specifies the group and the version used to register the objects.
var SchemeGroupVersion = schema.GroupVersion{Group: GroupName, Version: "v1alpha1"}
SchemeGroupVersion is group version used to register these objects Deprecated: use GroupVersion instead.
Functions ¶
func Resource ¶
func Resource(resource string) schema.GroupResource
Resource takes an unqualified resource and returns a Group qualified GroupResource
Types ¶
type FederatedHPA ¶
type FederatedHPA struct {
metav1.TypeMeta `json:",inline"`
metav1.ObjectMeta `json:"metadata,omitempty"`
// Spec is the specification of the FederatedHPASpec.
// +required
Spec FederatedHPASpec `json:"spec"`
// Status is the current status of the FederatedHPA.
// +optional
Status autoscalingv2.HorizontalPodAutoscalerStatus `json:"status"`
}
FederatedHPA is centralized HPA that can aggregate the metrics in multiple clusters. When the system load increases, it will query the metrics from multiple clusters and scales up the replicas. When the system load decreases, it will query the metrics from multiple clusters and scales down the replicas. After the replicas are scaled up/down, karmada-scheduler will schedule the replicas based on the policy.
func (*FederatedHPA) DeepCopy ¶
func (in *FederatedHPA) DeepCopy() *FederatedHPA
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new FederatedHPA.
func (*FederatedHPA) DeepCopyInto ¶
func (in *FederatedHPA) DeepCopyInto(out *FederatedHPA)
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
func (*FederatedHPA) DeepCopyObject ¶
func (in *FederatedHPA) DeepCopyObject() runtime.Object
DeepCopyObject is an autogenerated deepcopy function, copying the receiver, creating a new runtime.Object.
type FederatedHPAList ¶
type FederatedHPAList struct {
metav1.TypeMeta `json:",inline"`
metav1.ListMeta `json:"metadata,omitempty"`
Items []FederatedHPA `json:"items"`
}
FederatedHPAList contains a list of FederatedHPA.
func (*FederatedHPAList) DeepCopy ¶
func (in *FederatedHPAList) DeepCopy() *FederatedHPAList
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new FederatedHPAList.
func (*FederatedHPAList) DeepCopyInto ¶
func (in *FederatedHPAList) DeepCopyInto(out *FederatedHPAList)
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
func (*FederatedHPAList) DeepCopyObject ¶
func (in *FederatedHPAList) DeepCopyObject() runtime.Object
DeepCopyObject is an autogenerated deepcopy function, copying the receiver, creating a new runtime.Object.
type FederatedHPASpec ¶
type FederatedHPASpec struct {
// ScaleTargetRef points to the target resource to scale, and is used to
// the pods for which metrics should be collected, as well as to actually
// change the replica count.
// +required
ScaleTargetRef autoscalingv2.CrossVersionObjectReference `json:"scaleTargetRef"`
// minReplicas is the lower limit for the number of replicas to which the autoscaler
// can scale down. It defaults to 1 pod. minReplicas is allowed to be 0 if the
// alpha feature gate HPAScaleToZero is enabled and at least one Object or External
// metric is configured. Scaling is active as long as at least one metric value is
// available.
// +optional
MinReplicas *int32 `json:"minReplicas,omitempty" protobuf:"varint,2,opt,name=minReplicas"`
// maxReplicas is the upper limit for the number of replicas to which the autoscaler can scale up.
// It cannot be less that minReplicas.
MaxReplicas int32 `json:"maxReplicas" protobuf:"varint,3,opt,name=maxReplicas"`
// Metrics contains the specifications for which to use to calculate the
// desired replica count (the maximum replica count across all metrics will
// be used). The desired replica count is calculated multiplying the
// ratio between the target value and the current value by the current
// number of pods. Ergo, metrics used must decrease as the pod count is
// increased, and vice-versa. See the individual metric source types for
// more information about how each type of metric must respond.
// If not set, the default metric will be set to 80% average CPU utilization.
// +optional
Metrics []autoscalingv2.MetricSpec `json:"metrics,omitempty"`
// Behavior configures the scaling behavior of the target
// in both Up and Down directions (scaleUp and scaleDown fields respectively).
// If not set, the default HPAScalingRules for scale up and scale down are used.
// +optional
Behavior *autoscalingv2.HorizontalPodAutoscalerBehavior `json:"behavior,omitempty"`
}
FederatedHPASpec describes the desired functionality of the FederatedHPA.
