Constructor Details

V2HorizontalPodAutoscalerSpec

public V2HorizontalPodAutoscalerSpec()

Method Details

behavior

public V2HorizontalPodAutoscalerSpec behavior(V2HorizontalPodAutoscalerBehavior behavior)

getBehavior

@Nullable
public V2HorizontalPodAutoscalerBehavior getBehavior()

Get behavior

Returns:

behavior

setBehavior

public void setBehavior(V2HorizontalPodAutoscalerBehavior behavior)

maxReplicas

public V2HorizontalPodAutoscalerSpec maxReplicas(Integer maxReplicas)

getMaxReplicas

public Integer getMaxReplicas()

maxReplicas is the upper limit for the number of replicas to which the autoscaler can scale up. It cannot be less that minReplicas.

Returns:

maxReplicas

setMaxReplicas

public void setMaxReplicas(Integer maxReplicas)

metrics

public V2HorizontalPodAutoscalerSpec metrics(List<V2MetricSpec> metrics)

addMetricsItem

public V2HorizontalPodAutoscalerSpec addMetricsItem(V2MetricSpec metricsItem)

getMetrics

@Nullable
public List<V2MetricSpec> getMetrics()

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.

Returns:

metrics

setMetrics

public void setMetrics(List<V2MetricSpec> metrics)

minReplicas

public V2HorizontalPodAutoscalerSpec minReplicas(Integer minReplicas)

getMinReplicas

@Nullable
public Integer getMinReplicas()

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.

Returns:

minReplicas

setMinReplicas

public void setMinReplicas(Integer minReplicas)

scaleTargetRef

public V2HorizontalPodAutoscalerSpec scaleTargetRef(V2CrossVersionObjectReference scaleTargetRef)

getScaleTargetRef

public V2CrossVersionObjectReference getScaleTargetRef()

Get scaleTargetRef

Returns:

scaleTargetRef

setScaleTargetRef

public void setScaleTargetRef(V2CrossVersionObjectReference scaleTargetRef)
