|===
| Property | Type | Description

| `apiVersion`
| `string`
| APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

| `kind`
| `string`
| Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

|===
| Property | Type | Description

| `behavior`
| `object`
| HorizontalPodAutoscalerBehavior configures the scaling behavior of the target in both Up and Down directions (scaleUp and scaleDown fields respectively).

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

| `metrics`
| `array`
| 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.

| `metrics[]`
| `object`
| MetricSpec specifies how to scale based on a single metric (only `type` and one other matching field should be set at once).

| `minReplicas`
| `integer`
| 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.

| `scaleTargetRef`
| `object`
| CrossVersionObjectReference contains enough information to let you identify the referred resource.

|===
| Property | Type | Description

| `scaleDown`
| `object`
| HPAScalingRules configures the scaling behavior for one direction via scaling Policy Rules and a configurable metric tolerance.

Scaling Policy Rules are applied after calculating DesiredReplicas from metrics for the HPA. They can limit the scaling velocity by specifying scaling policies. They can prevent flapping by specifying the stabilization window, so that the number of replicas is not set instantly, instead, the safest value from the stabilization window is chosen.

The tolerance is applied to the metric values and prevents scaling too eagerly for small metric variations. (Note that setting a tolerance requires the beta HPAConfigurableTolerance feature gate to be enabled.)

| `scaleUp`

| HPAScalingRules configures the scaling behavior for one direction via scaling Policy Rules and a configurable metric tolerance.

Scaling Policy Rules are applied after calculating DesiredReplicas from metrics for the HPA. They can limit the scaling velocity by specifying scaling policies.

| Property | Type | Description

| `policies`
| `array`
| policies is a list of potential scaling polices which can be used during scaling. If not set, use the default values: - For scale up: allow doubling the number of pods, or an absolute change of 4 pods in a 15s window. - For scale down: allow all pods to be removed in a 15s window.

| `policies[]`
| `object`
| HPAScalingPolicy is a single policy which must hold true for a specified past interval.

| `selectPolicy`
| `string`
| selectPolicy is used to specify which policy should be used. If not set, the default value Max is used.

| `stabilizationWindowSeconds`
| `integer`
| stabilizationWindowSeconds is the number of seconds for which past recommendations should be considered while scaling up or scaling down. StabilizationWindowSeconds must be greater than or equal to zero and less than or equal to 3600 (one hour). If not set, use the default values: - For scale up: 0 (i.e. no stabilization is done). - For scale down: 300 (i.e. the stabilization window is 300 seconds long).

| `tolerance`
| xref:../objects/index.adoc#io-k8s-apimachinery-pkg-api-resource-Quantity[`Quantity`]
| tolerance is the tolerance on the ratio between the current and desired metric value under which no updates are made to the desired number of replicas (e.g. 0.01 for 1%). Must be greater than or equal to zero. If not set, the default cluster-wide tolerance is applied (by default 10%).

For example, if autoscaling is configured with a memory consumption target of 100Mi, and scale-down and scale-up tolerances of 5% and 1% respectively, scaling will be triggered when the actual consumption falls below 95Mi or exceeds 101Mi.

This is an beta field and requires the HPAConfigurableTolerance feature gate to be enabled.

| `containerResource`
| `object`
| ContainerResourceMetricStatus indicates the current value of a resource metric known to Kubernetes, as specified in requests and limits, describing a single container in each pod in the current scale target (e.g. CPU or memory).

.Query parameters
[cols="1,1,2",options="header"]
|===
| Parameter | Type | Description
| `dryRun`
| `string`
| When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
| `fieldValidation`
| `string`
| fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
