参数

参数类型

描述

aggregationRule

io.k8s.api.rbac.v1.AggregationRule object

AggregationRule is an optional field that describes how to build the Rules for this ClusterRole. If AggregationRule is set, then the Rules are controller managed and direct changes to Rules will be stomped by the controller.

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

io.k8s.apimachinery.pkg.apis.meta.v1.ObjectMeta object

Standard object's metadata.

rules

Array of io.k8s.api.rbac.v1.PolicyRule objects

Rules holds all the PolicyRules for this ClusterRole

表5 io.k8s.api.rbac.v1.AggregationRule

参数

参数类型

描述

clusterRoleSelectors

Array of io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelector objects

ClusterRoleSelectors holds a list of selectors which will be used to find ClusterRoles and create the rules. If any of the selectors match, then the ClusterRole's permissions will be added

表6 io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelector

参数

参数类型

描述

matchExpressions

Array of io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelectorRequirement objects

matchExpressions is a list of label selector requirements. The requirements are ANDed.

matchLabels

Map<String,String>

matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.

表7 io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelectorRequirement

参数

参数类型

描述

key

String

key is the label key that the selector applies to.

operator

String

operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

values

Array of strings

values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.

表8 io.k8s.apimachinery.pkg.apis.meta.v1.ObjectMeta

参数

参数类型

描述

annotations

Map<String,String>

Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: http://kubernetes.io/docs/user-guide/annotations

clusterName

String

The name of the cluster which the object belongs to. This is used to distinguish resources with same name and namespace in different clusters. This field is not set anywhere right now and apiserver is going to ignore it if set in create or update request.

creationTimestamp

String

CreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.

Populated by the system. Read-only. Null for lists. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

deletionGracePeriodSeconds

Long

Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened. Read-only.

deletionTimestamp

String

DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.

Populated by the system when a graceful deletion is requested. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

finalizers

Array of strings

Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list.

generateName

String

GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.

If this field is specified and the generated name exists, the server will NOT return a 409 - instead, it will either return 201 Created or 500 with Reason ServerTimeout indicating a unique name could not be found in the time allotted, and the client should retry (optionally after the time indicated in the Retry-After header).

Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency

generation

Long

A sequence number representing a specific generation of the desired state. Populated by the system. Read-only.

labels

Map<String,String>

Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: http://kubernetes.io/docs/user-guide/labels

managedFields

Array of io.k8s.apimachinery.pkg.apis.meta.v1.ManagedFieldsEntry objects

ManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn't need to set or understand this field. A workflow can be the user's name, a controller's name, or the name of a specific apply path like "ci-cd". The set of fields is always in the version that the workflow used when modifying the object.

name

String

Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/identifiers#names

namespace

String

Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.

Must be a DNS_LABEL. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/namespaces

ownerReferences

Array of io.k8s.apimachinery.pkg.apis.meta.v1.OwnerReference objects

List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.

resourceVersion

String

An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed. May be used for optimistic concurrency, change detection, and the watch operation on a resource or set of resources. Clients must treat these values as opaque and passed unmodified back to the server. They may only be valid for a particular resource or set of resources.

Populated by the system. Read-only. Value must be treated as opaque by clients and . More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency

selfLink

String

SelfLink is a URL representing this object. Populated by the system. Read-only.

DEPRECATED Kubernetes will stop propagating this field in 1.20 release and the field is planned to be removed in 1.21 release.

uid

String

UID is the unique in time and space value for this object. It is typically generated by the server on successful creation of a resource and is not allowed to change on PUT operations.

Populated by the system. Read-only. More info: http://kubernetes.io/docs/user-guide/identifiers#uids

表9 io.k8s.apimachinery.pkg.apis.meta.v1.ManagedFieldsEntry

参数

参数类型

描述

apiVersion

String

APIVersion defines the version of this resource that this field set applies to. The format is "group/version" just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.

fieldsType

String

FieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"

fieldsV1

Object

FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.

manager

String

Manager is an identifier of the workflow managing these fields.

operation

String

Operation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.

time

String

Time is timestamp of when these fields were set. It should always be empty if Operation is 'Apply'

参数

参数类型

描述

apiVersion

String

API version of the referent.

blockOwnerDeletion

Boolean

If true, AND if the owner has the "foregroundDeletion" finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.

controller

Boolean

If true, this reference points to the managing controller.

kind

String

Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

name

String

Name of the referent. More info: http://kubernetes.io/docs/user-guide/identifiers#names

表11 io.k8s.api.rbac.v1.PolicyRule

参数

参数类型

描述

apiGroups

Array of strings

APIGroups is the name of the APIGroup that contains the resources. If multiple API groups are specified, any action requested against one of the enumerated resources in any API group will be allowed.

nonResourceURLs

Array of strings

NonResourceURLs is a set of partial urls that a user should have access to. *s are allowed, but only as the full, final step in the path Since non-resource URLs are not namespaced, this field is only applicable for ClusterRoles referenced from a ClusterRoleBinding. Rules can either apply to API resources (such as "pods" or "secrets") or non-resource URL paths (such as "/api"), but not both.

resourceNames

Array of strings

ResourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.

resources

Array of strings

Resources is a list of resources this rule applies to. ResourceAll represents all resources.

verbs

Array of strings

Verbs is a list of Verbs that apply to ALL the ResourceKinds and AttributeRestrictions contained in this rule. VerbAll represents all kinds.
