Reading a Specified Secret

Function

This API is used to read the details about a specified Secret object.

URI

GET /api/v1/namespaces/{namespace}/secrets/{name}

Table 1 describes the parameters of this API.

Table 1 Parameter description

Parameter

Mandatory

Description

pretty

No

If 'true', then the output is pretty printed.

namespace

Yes

Object name and auth scope, such as for teams and projects.

name

Yes

Name of the Secret.

exact

No

Should the export be exact. Exact export maintains cluster-specific fields like 'Namespace'.

export

No

Should this value be exported. Export strips fields that a user cannot specify.

Request

N/A

Response

Response parameters:

Table 2 describes the response parameters.

Table 2 Parameter description

Parameter

Type

Description

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.

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.

metadata

Table 3

-

data

object

Data contains the secret data. Each key must be a valid DNS_SUBDOMAIN or leading dot followed by valid DNS_SUBDOMAIN. The serialized form of the secret data is a base64 encoded string, representing the arbitrary (possibly non-string) data value here.

type

String

Used to facilitate programmatic handling of secret data.

Table 3 Data structure of the metadata field

Parameter

Type

Description

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.

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.

namespace

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.

selfLink

String

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

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.

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.

generation

Integer

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

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.

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 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

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.

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.

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.

ownerReferences

Table 4

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

String array

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.

Table 4 Data structure of the ownerReferences field

Parameter

Type

Description

apiVersion

String

API version of the referent.

kind

String

Kind of the referent.

name

String

Name of the referent.

uid

String

UID of the referent.

controller

Boolean

If true, this reference points to the managing controller.
