Abstract

This document describes the OpenShift Container Platform schedule and quota API objects and their detailed specifications.

Chapter 1. Schedule and quota APIs

1.1. AppliedClusterResourceQuota [quota.openshift.io/v1]

Description

AppliedClusterResourceQuota mirrors ClusterResourceQuota at a project scope, for projection into a project. It allows a project-admin to know which ClusterResourceQuotas are applied to his project and their associated usage.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

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.

Required
  • verbs
  • apiGroups
  • resources
PropertyTypeDescription

apiGroups

array (string)

apiGroups is a list of matching API groups and may not be empty. "*" matches all API groups and, if present, must be the only entry. Required.

clusterScope

namespaces is a list of target namespaces that restricts matches. A request that specifies a target namespace matches only if either (a) this list contains that target namespace or (b) this list contains "". Note that "" matches any specified namespace but does not match a request that does not specify a namespace (see the clusterScope field for that). This list may be empty, but only if clusterScope is true.

resources

array (string)

resources is a list of matching resources (i.e., lowercase and plural) with, if desired, subresource. For example, [ "services", "nodes/status" ]. This list may not be empty. "*" matches all resources and, if present, must be the only entry. Required.

verbs

array (string)

verbs is a list of matching verbs and may not be empty. "*" matches all verbs and, if present, must be the only entry. Required.

Chapter 7. PriorityLevelConfiguration [flowcontrol.apiserver.k8s.io/v1]

Description
PriorityLevelConfiguration represents the configuration of a priority level.
Type
object

7.1. Specification

PropertyTypeDescription

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’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

spec

object

PriorityLevelConfigurationSpec specifies the configuration of a priority level.

status

object

PriorityLevelConfigurationStatus represents the current state of a "request-priority".

7.1.1. .spec

Description
PriorityLevelConfigurationSpec specifies the configuration of a priority level.
Type
object
Required
  • type
PropertyTypeDescription

exempt

object

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.

limited

object

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?

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.

7.1.2. .spec.exempt

Description
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.
Type
object
PropertyTypeDescription

lendablePercent

integer

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 )

nominalConcurrencyShares

integer

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.

7.1.3. .spec.limited

Description
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?
Type
object
PropertyTypeDescription

borrowingLimitPercent

integer

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.

lendablePercent

integer

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 )

limitResponse

object

LimitResponse defines how to handle requests that can not be executed right now.

nominalConcurrencyShares

integer

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)

7.1.4. .spec.limited.limitResponse

Description
LimitResponse defines how to handle requests that can not be executed right now.
Type
object
Required
  • type
PropertyTypeDescription

queuing

object

QueuingConfiguration holds the configuration parameters for queuing

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.

7.1.5. .spec.limited.limitResponse.queuing

Description
QueuingConfiguration holds the configuration parameters for queuing
Type
object
PropertyTypeDescription

handSize

integer

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.

queueLengthLimit

integer

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.

queues

integer

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.

7.1.6. .status

Description
PriorityLevelConfigurationStatus represents the current state of a "request-priority".
Type
object
PropertyTypeDescription

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.
