表11 metadata字段数据结构说明

参数

是否必选

参数类型

描述

name

Yes

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.

0 characters < name length ≤ 253 characters.

The name must be a regular expression [a-z0-9]([-a-z0-9]*[a-z0-9])?.

clusterName

No

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.

initializers

No

initializers object

An initializer is a controller which enforces some system invariant at object creation time. This field is a list of initializers that have not yet acted on this object. If nil or empty, this object has been completely initialized. Otherwise, the object is considered uninitialized and is hidden (in list/watch and get calls) from clients that haven't explicitly asked to observe uninitialized objects. When an object is created, the system will populate this list with the current set of initializers. Only privileged users may set or modify this list. Once it is empty, it may not be modified further by any user.

enable

No

Boolean

Enable identify whether the resource is available.

generateName

No

String

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.

0 characters < generated name length ≤ 253 characters.

The generated name must be a regular expression [a-z0-9]([-a-z0-9]*[a-z0-9])?.

namespace

No

String

Namespace defines the space within 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.

0 characters < namespace length ≤ 63 characters.

The namespace must be a regular expression [a-z0-9]([-a-z0-9]*[a-z0-9])?.

说明:

This field is automatically generated. Do not assign any value to this field. Otherwise, API calls would fail.

resourceVersion

No

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.

说明:

This field is automatically generated. Do not assign any value to this field. Otherwise, API calls would fail.

generation

No

Integer

String

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.

说明:

This field is automatically generated. Do not assign any value to this field. Otherwise, API calls would fail.

deletionTimestamp

No

String

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 will be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field. Once 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. Once the resource is deleted in the API, the Kubelet will send a hard termination signal to the container. If not set, graceful deletion of the object has not been requested. Populated by the system when a graceful deletion is requested. Read-only.

deletionGracePeriodSeconds

No

Integer

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.

ownerReferences

No

ownerReferences object

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.

finalizers

No

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.

stdinOnce

No

Boolean

A flag indicating whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true, the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container process that reads from stdin will never receive an EOF. Default is false.

tty

No

Boolean

A flag indicating whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false.
