Method Detail

create

@Stability(Stable)
public static HorizontalPodAutoscaler.Builder create(software.constructs.Construct scope,
                                                     String id)

Parameters:

scope - This parameter is required.

id - This parameter is required.

Returns:

a new instance of HorizontalPodAutoscaler.Builder.

metadata

@Stability(Stable)
public HorizontalPodAutoscaler.Builder metadata(org.cdk8s.ApiObjectMetadata metadata)

Metadata that all persisted resources must have, which includes all objects users must create.

Parameters:

metadata - Metadata that all persisted resources must have, which includes all objects users must create. This parameter is required.

Returns:

this

maxReplicas

@Stability(Stable)
public HorizontalPodAutoscaler.Builder maxReplicas(Number maxReplicas)

The maximum number of replicas that can be scaled up to.

Parameters:

maxReplicas - The maximum number of replicas that can be scaled up to. This parameter is required.

Returns:

this

target

@Stability(Stable)
public HorizontalPodAutoscaler.Builder target(IScalable target)

The workload to scale up or down.

Scalable workload types:

• Deployment
• StatefulSet

Parameters:

target - The workload to scale up or down. This parameter is required.

Returns:

this

metrics

@Stability(Stable)
public HorizontalPodAutoscaler.Builder metrics(List<? extends Metric> metrics)

The metric conditions that trigger a scale up or scale down.

Default: - If metrics are not provided, then the target resource constraints (e.g. cpu limit) will be used as scaling metrics.

Parameters:

metrics - The metric conditions that trigger a scale up or scale down. This parameter is required.

Returns:

this

minReplicas

@Stability(Stable)
public HorizontalPodAutoscaler.Builder minReplicas(Number minReplicas)

The minimum number of replicas that can be scaled down to.

Can be set to 0 if the alpha feature gate HPAScaleToZero is enabled and at least one Object or External metric is configured.

Default: 1

Parameters:

minReplicas - The minimum number of replicas that can be scaled down to. This parameter is required.

Returns:

this

scaleDown

@Stability(Stable)
public HorizontalPodAutoscaler.Builder scaleDown(ScalingRules scaleDown)

The scaling behavior when scaling down.

Default: - Scale down to minReplica count with a 5 minute stabilization window.

Parameters:

scaleDown - The scaling behavior when scaling down. This parameter is required.

Returns:

this

scaleUp

@Stability(Stable)
public HorizontalPodAutoscaler.Builder scaleUp(ScalingRules scaleUp)

The scaling behavior when scaling up.

Default: - Is the higher of: * Increase no more than 4 pods per 60 seconds * Double the number of pods per 60 seconds

Parameters:

scaleUp - The scaling behavior when scaling up. This parameter is required.

Returns:

this

build

@Stability(Stable)
public HorizontalPodAutoscaler build()

Specified by:

build in interface software.amazon.jsii.Builder<HorizontalPodAutoscaler>

Returns:

a newly built instance of HorizontalPodAutoscaler.
