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. 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 |
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. |

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. |

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.

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. 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. |

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.

2 - PriorityLevelConfiguration
PriorityLevelConfiguration represents the configuration of a priority level.
apiVersion: flowcontrol.apiserver.k8s.io/v1
import "k8s.io/api/flowcontrol/v1"
PriorityLevelConfiguration
PriorityLevelConfiguration represents the configuration of a priority level.
| Field | Description |
|---|---|
apiVersionstring |
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 |
kindstring |
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 |
metadataObjectMeta |
`metadata` is the standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata |
specPriorityLevelConfigurationSpec |
`spec` is the specification of the desired behavior of a "request-priority". More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status |
statusPriorityLevelConfigurationStatus |
`status` is the current status of a "request-priority". More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status |
PriorityLevelConfigurationSpec
PriorityLevelConfigurationSpec specifies the configuration of a priority level.
| Field | Description |
|---|---|
exemptExemptPriorityLevelConfiguration |
`exempt` specifies how requests are handled for an exempt priority level. This field MUST be empty if `type` is `"Limited"`. This field MAY be non-empty if `type` is `"Exempt"`. If empty and `type` is `"Exempt"` then the default values for `ExemptPriorityLevelConfiguration` apply. |
limitedLimitedPriorityLevelConfiguration |
`limited` specifies how requests are handled for a Limited priority level. This field must be non-empty if and only if `type` is `"Limited"`. |
type *string |
`type` indicates whether this priority level is subject to limitation on request execution. A value of `"Exempt"` means that requests of this priority level are not subject to a limit (and thus are never queued) and do not detract from the capacity made available to other priority levels. A value of `"Limited"` means that (a) requests of this priority level _are_ subject to limits and (b) some of the server's limited capacity is made available exclusively to this priority level. Required. |
PriorityLevelConfigurationStatus
PriorityLevelConfigurationStatus represents the current state of a "request-priority".
| Field | Description |
|---|---|
conditionsPriorityLevelConfigurationCondition array patch strategy: merge on key type |
`conditions` is the current state of "request-priority". |
PriorityLevelConfigurationList
PriorityLevelConfigurationList is a list of PriorityLevelConfiguration objects.
| Field | Description |
|---|---|
apiVersionstring |
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 |
items *PriorityLevelConfiguration array |
`items` is a list of request-priorities. |
kindstring |
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 |
metadataListMeta |
`metadata` is the standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata |
ExemptPriorityLevelConfiguration
ExemptPriorityLevelConfiguration describes the configurable aspects of the handling of exempt requests. In the mandatory exempt configuration object the values in the fields here can be modified by authorized users, unlike the rest of the spec.
| Field | Description |
|---|---|
lendablePercentinteger |
`lendablePercent` prescribes the fraction of the level's NominalCL that can be borrowed by other priority levels. This value of this field must be between 0 and 100, inclusive, and it defaults to 0. The number of seats that other levels can borrow from this level, known as this level's LendableConcurrencyLimit (LendableCL), is defined as follows. LendableCL(i) = round( NominalCL(i) * lendablePercent(i)/100.0 ) |
nominalConcurrencySharesinteger |
`nominalConcurrencyShares` (NCS) contributes to the computation of the NominalConcurrencyLimit (NominalCL) of this level. This is the number of execution seats nominally reserved for this priority level. This DOES NOT limit the dispatching from this priority level but affects the other priority levels through the borrowing mechanism. The server's concurrency limit (ServerCL) is divided among all the priority levels in proportion to their NCS values: NominalCL(i) = ceil( ServerCL * NCS(i) / sum_ncs ) sum_ncs = sum[priority level k] NCS(k) Bigger numbers mean a larger nominal concurrency limit, at the expense of every other priority level. This field has a default value of zero. |
LimitResponse
LimitResponse defines how to handle requests that can not be executed right now.
| Field | Description |
|---|---|
queuingQueuingConfiguration |
`queuing` holds the configuration parameters for queuing. This field may be non-empty only if `type` is `"Queue"`. |
type *string |
`type` is "Queue" or "Reject". "Queue" means that requests that can not be executed upon arrival are held in a queue until they can be executed or a queuing limit is reached. "Reject" means that requests that can not be executed upon arrival are rejected. Required. |
LimitedPriorityLevelConfiguration
LimitedPriorityLevelConfiguration specifies how to handle requests that are subject to limits. It addresses two issues:
- How are requests for this priority level limited?
- What should be done with requests that exceed the limit?
| Field | Description |
|---|---|
borrowingLimitPercentinteger |
`borrowingLimitPercent`, if present, configures a limit on how many seats this priority level can borrow from other priority levels. The limit is known as this level's BorrowingConcurrencyLimit (BorrowingCL) and is a limit on the total number of seats that this level may borrow at any one time. This field holds the ratio of that limit to the level's nominal concurrency limit. When this field is non-nil, it must hold a non-negative integer and the limit is calculated as follows. BorrowingCL(i) = round( NominalCL(i) * borrowingLimitPercent(i)/100.0 ) The value of this field can be more than 100, implying that this priority level can borrow a number of seats that is greater than its own nominal concurrency limit (NominalCL). When this field is left `nil`, the limit is effectively infinite. |
lendablePercentinteger |
`lendablePercent` prescribes the fraction of the level's NominalCL that can be borrowed by other priority levels. The value of this field must be between 0 and 100, inclusive, and it defaults to 0. The number of seats that other levels can borrow from this level, known as this level's LendableConcurrencyLimit (LendableCL), is defined as follows. LendableCL(i) = round( NominalCL(i) * lendablePercent(i)/100.0 ) |
limitResponseLimitResponse |
`limitResponse` indicates what to do with requests that can not be executed right now |
nominalConcurrencySharesinteger |
`nominalConcurrencyShares` (NCS) contributes to the computation of the NominalConcurrencyLimit (NominalCL) of this level. This is the number of execution seats available at this priority level. This is used both for requests dispatched from this priority level as well as requests dispatched from other priority levels borrowing seats from this level. The server's concurrency limit (ServerCL) is divided among the Limited priority levels in proportion to their NCS values: NominalCL(i) = ceil( ServerCL * NCS(i) / sum_ncs ) sum_ncs = sum[priority level k] NCS(k) Bigger numbers mean a larger nominal concurrency limit, at the expense of every other priority level. If not specified, this field defaults to a value of 30. Setting this field to zero supports the construction of a "jail" for this priority level that is used to hold some request(s) |
PriorityLevelConfigurationCondition
PriorityLevelConfigurationCondition defines the condition of priority level.
| Field | Description |
|---|---|
lastTransitionTimeTime |
`lastTransitionTime` is the last time the condition transitioned from one status to another. |
messagestring |
`message` is a human-readable message indicating details about last transition. |
reasonstring |
`reason` is a unique, one-word, CamelCase reason for the condition's last transition. |
statusstring |
`status` is the status of the condition. Can be True, False, Unknown. Required. |
typestring |
`type` is the type of the condition. Required. |
QueuingConfiguration
QueuingConfiguration holds the configuration parameters for queuing
| Field | Description |
|---|---|
handSizeinteger |
`handSize` is a small positive number that configures the shuffle sharding of requests into queues. When enqueuing a request at this priority level the request's flow identifier (a string pair) is hashed and the hash value is used to shuffle the list of queues and deal a hand of the size specified here. The request is put into one of the shortest queues in that hand. `handSize` must be no larger than `queues`, and should be significantly smaller (so that a few heavy flows do not saturate most of the queues). See the user-facing documentation for more extensive guidance on setting this field. This field has a default value of 8. |
queueLengthLimitinteger |
`queueLengthLimit` is the maximum number of requests allowed to be waiting in a given queue of this priority level at a time; excess requests are rejected. This value must be positive. If not specified, it will be defaulted to 50. |
queuesinteger |
`queues` is the number of queues for this priority level. The queues exist independently at each apiserver. The value must be positive. Setting it to 1 effectively precludes shufflesharding and thus makes the distinguisher method of associated flow schemas irrelevant. This field has a default value of 64. |

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 |
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. |

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.

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. |

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. 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. |

integer | Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. |

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.

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. |
