Field	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
metadata ObjectMeta	metadata is the standard object metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
spec * HorizontalPodAutoscalerSpec	spec is the specification for the behaviour of the autoscaler. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status.
status HorizontalPodAutoscalerStatus	status is the current information about the autoscaler.

HorizontalPodAutoscalerSpec

HorizontalPodAutoscalerSpec describes the desired functionality of the HorizontalPodAutoscaler.

---

Field	Description
behavior HorizontalPodAutoscalerBehavior	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.
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 MetricSpec 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.
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 * CrossVersionObjectReference	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.

---

Field	Description
conditions HorizontalPodAutoscalerCondition array patch strategy: merge on key type	conditions is the set of conditions required for this autoscaler to scale its target, and indicates whether or not those conditions are met.
currentMetrics MetricStatus array	currentMetrics is the last read state of the metrics used by this autoscaler.
currentReplicas integer	currentReplicas is current number of replicas of pods managed by this autoscaler, as last seen by the autoscaler.
desiredReplicas * integer	desiredReplicas is the desired number of replicas of pods managed by this autoscaler, as last calculated by the autoscaler.
lastScaleTime Time	lastScaleTime is the last time the HorizontalPodAutoscaler scaled the number of pods, used by the autoscaler to control how often the number of pods is changed.
observedGeneration integer	observedGeneration is the most recent generation observed by this autoscaler.

ContainerResourceMetricSource

ContainerResourceMetricSource indicates how to scale on a resource metric known to Kubernetes, as specified in requests and limits, describing each pod in the current scale target (e.g. CPU or memory). The values will be averaged together before being compared to the target.

---

Field	Description
container * string	container is the name of the container in the pods of the scaling target
name * string	name is the name of the resource in question.
target * MetricTarget	target specifies the target value for the given metric

ContainerResourceMetricStatus

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). Such metrics are built in to Kubernetes, and have special scaling options on top of those available to normal per-pod metrics using the "pods" source.

---

Field	Description
container * string	container is the name of the container in the pods of the scaling target
current * MetricValueStatus	current contains the current value for the given metric
name * string	name is the name of the resource in question.

Field	Description
apiVersion string	apiVersion is the API version of the referent
kind * string	kind is the kind of the referent; More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
name * string	name is the name of the referent; More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names

ExternalMetricSource

ExternalMetricSource indicates how to scale on a metric not associated with any Kubernetes object (for example length of queue in cloud messaging service, or QPS from loadbalancer running outside of cluster).

---

Field	Description

ExternalMetricStatus

ExternalMetricStatus indicates the current value of a global metric not associated with any Kubernetes object.

---

Field	Description
current * MetricValueStatus	current contains the current value for the given metric
metric * MetricIdentifier	metric identifies the target metric by name and selector

HPAScalingPolicy

HPAScalingPolicy is a single policy which must hold true for a specified past interval.

---

Field	Description
periodSeconds * integer	periodSeconds specifies the window of time for which the policy should hold true. PeriodSeconds must be greater than zero and less than or equal to 1800 (30 min).
type * string	type is used to specify the scaling policy.
value * integer	value contains the amount of change which is permitted by the policy. It must be greater than zero

HPAScalingRules

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.)

---

Field	Description
policies HPAScalingPolicy 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.
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 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.

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

---

Field	Description
scaleDown HPAScalingRules	scaleDown is scaling policy for scaling Down. If not set, the default value is to allow to scale down to minReplicas pods, with a 300 second stabilization window (i.e., the highest recommendation for the last 300sec is used).
scaleUp HPAScalingRules	scaleUp is scaling policy for scaling Up. If not set, the default value is the higher of: * increase no more than 4 pods per 60 seconds * double the number of pods per 60 seconds No stabilization is used.

Path Parameters

Name	Type	Description
name	string	name of the HorizontalPodAutoscaler
namespace	string	object name and auth scope, such as for teams and projects

Query Parameters

Name	Type	Description
pretty	string	If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
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
gracePeriodSeconds	integer	The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential	boolean	if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage.

The default value is false, and the user must opt in to enable it
orphanDependents	boolean	Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy	string	Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

HTTP Request

DELETE /apis/autoscaling/v2/namespaces/{namespace}/horizontalpodautoscalers

Path Parameters

Name	Type	Description
namespace	string	object name and auth scope, such as for teams and projects

Query Parameters

Name	Type	Description
pretty	string	If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue	string	The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
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
fieldSelector	string	A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds	integer	The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential	boolean	if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector	string	A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit	integer	limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents	boolean	Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy	string	Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion	string	resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch	string	resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents	boolean	`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector	string	shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Query Parameters

Name	Type	Description
pretty	string	If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks	boolean	allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue	string	The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector	string	A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector	string	A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit	integer	limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion	string	resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch	string	resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents	boolean	`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned.

shardSelector	string	shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds	integer	Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch	boolean	Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

get Watch List All Namespaces

HTTP Request

GET /apis/autoscaling/v2/watch/horizontalpodautoscalers

Query Parameters

Name	Type	Description
allowWatchBookmarks	boolean	allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue	string	The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector	string	A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector	string	A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit	integer	limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty	string	If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion	string	resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch	string	resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents	boolean	`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector	string	shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space.

Path Parameters

Name	Type	Description
name	string	name of the HorizontalPodAutoscaler
namespace	string	object name and auth scope, such as for teams and projects

Query Parameters

Name	Type	Description
pretty	string	If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
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
fieldManager	string	fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
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.
