8.2.1. Specification
Property | Type | Description |
---|---|---|
|
| 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 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 |
| Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata | |
|
| TokenRequestSpec contains client provided parameters of a token request. |
|
| TokenRequestStatus is the result of a token request. |
8.2.1.1. .spec
- Description
- TokenRequestSpec contains client provided parameters of a token request.
- Type
-
object
- Required
-
audiences
-
Property | Type | Description |
---|---|---|
|
| Audiences are the intendend audiences of the token. A recipient of a token must identify themself with an identifier in the list of audiences of the token, and otherwise should reject the token. A token issued for multiple audiences may be used to authenticate against any of the audiences listed but implies a high degree of trust between the target audiences. |
|
| BoundObjectReference is a reference to an object that a token is bound to. |
|
| ExpirationSeconds is the requested duration of validity of the request. The token issuer may return a token with a different validity duration so a client needs to check the 'expiration' field in a response. |
8.2.1.2. .spec.boundObjectRef
- Description
- BoundObjectReference is a reference to an object that a token is bound to.
- Type
-
object
Property | Type | Description |
---|---|---|
|
| API version of the referent. |
|
| Kind of the referent. Valid kinds are 'Pod' and 'Secret'. |
|
| Name of the referent. |
|
| UID of the referent. |
8.2.1.3. .status
- Description
- TokenRequestStatus is the result of a token request.
- Type
-
object
- Required
-
token
-
expirationTimestamp
-
Property | Type | Description |
---|---|---|
| ExpirationTimestamp is the time of expiration of the returned token. | |
|
| Token is the opaque bearer token. |
8.2.2. API endpoints
The following API endpoints are available:
/api/v1/namespaces/{namespace}/serviceaccounts/{name}/token
-
POST
: create token of a ServiceAccount
-
8.2.2.1. /api/v1/namespaces/{namespace}/serviceaccounts/{name}/token
Parameter | Type | Description |
---|---|---|
|
| name of the TokenRequest |
|
| object name and auth scope, such as for teams and projects |
Parameter | Type | Description |
---|---|---|
|
| 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 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 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. |
|
| If 'true', then the output is pretty printed. |

|
| TokenReviewSpec is a description of the token authentication request. |
|
| TokenReviewStatus is the result of the token authentication request. |
8.3.1.1. .spec
- Description
- TokenReviewSpec is a description of the token authentication request.
- Type
-
object
Property | Type | Description |
---|---|---|
|
| Audiences is a list of the identifiers that the resource server presented with the token identifies as. Audience-aware token authenticators will verify that the token was intended for at least one of the audiences in this list. If no audiences are provided, the audience will default to the audience of the Kubernetes apiserver. |
|
| Token is the opaque bearer token. |
8.3.1.2. .status
- Description
- TokenReviewStatus is the result of the token authentication request.
- Type
-
object
Property | Type | Description |
---|---|---|
|
| Audiences are audience identifiers chosen by the authenticator that are compatible with both the TokenReview and token. An identifier is any identifier in the intersection of the TokenReviewSpec audiences and the token’s audiences. A client of the TokenReview API that sets the spec.audiences field should validate that a compatible audience identifier is returned in the status.audiences field to ensure that the TokenReview server is audience aware. If a TokenReview returns an empty status.audience field where status.authenticated is "true", the token is valid against the audience of the Kubernetes API server. |
|
| Authenticated indicates that the token was associated with a known user. |
|
| Error indicates that the token couldn’t be checked |
|
| UserInfo holds the information about the user needed to implement the user.Info interface. |
8.3.1.3. .status.user
- Description
- UserInfo holds the information about the user needed to implement the user.Info interface.

|
| The names of groups this user is a part of. |
|
| A unique value that identifies this user across time. If this user is deleted and another user by the same name is added, they will have different UIDs. |
|
| The name that uniquely identifies this user among all active users. |
8.3.1.4. .status.user.extra
