Authentication [config.openshift.io/v1]

oauthMetadata

object

oauthMetadata contains the discovery endpoint data for OAuth 2.0 Authorization Server Metadata for an external OAuth server. This discovery document can be viewed from its served location: oc get --raw '/.well-known/oauth-authorization-server' For further details, see the IETF Draft: https://tools.ietf.org/html/draft-ietf-oauth-discovery-04#section-2 If oauthMetadata.name is non-empty, this value has precedence over any metadata reference stored in status. The key "oauthMetadata" is used to locate the data. If specified and the config map or expected key is not found, no metadata is served. If the specified metadata is not valid, no metadata is served. The namespace for this config map is openshift-config.

oidcProviders

array

oidcProviders are OIDC identity providers that can issue tokens for this cluster Can only be set if "Type" is set to "OIDC".

At most one provider can be configured.

oidcProviders[]

object

serviceAccountIssuer

string

serviceAccountIssuer is the identifier of the bound service account token issuer. The default is https://kubernetes.default.svc WARNING: Updating this field will not result in immediate invalidation of all bound tokens with the previous issuer value. Instead, the tokens issued by previous service account issuer will continue to be trusted for a time period chosen by the platform (currently set to 24h). This time period is subject to change over time. This allows internal components to transition to use new service account issuer without service distruption.

type

string

type identifies the cluster managed, user facing authentication mode in use. Specifically, it manages the component that responds to login attempts. The default is IntegratedOAuth.

webhookTokenAuthenticator

object

webhookTokenAuthenticator configures a remote token reviewer. These remote authentication webhooks can be used to verify bearer tokens via the tokenreviews.authentication.k8s.io REST API. This is required to honor bearer tokens that are provisioned by an external authentication service.

Can only be set if "Type" is set to "None".

webhookTokenAuthenticators

array

webhookTokenAuthenticators is DEPRECATED, setting it has no effect.

webhookTokenAuthenticators[]

object

deprecatedWebhookTokenAuthenticator holds the necessary configuration options for a remote token authenticator. It’s the same as WebhookTokenAuthenticator but it’s missing the 'required' validation on KubeConfig field.

When set to 'NoPrefix', no prefix will be prepended to the value of the JWT claim.

When omitted, this means no opinion and the platform is left to choose any prefixes that are applied which is subject to change over time. Currently, the platform prepends {issuerURL}# to the value of the JWT claim when the claim is not 'email'. As an example, consider the following scenario: prefix is unset, issuerURL is set to https://myoidc.tld, the JWT claims include "username":"userA" and "email":"userA@myoidc.tld", and claim is set to: - "username": the mapped value will be "https://myoidc.tld#userA" - "email": the mapped value will be "userA@myoidc.tld"

dryRun

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.
