func Claims Uses

func Claims(sa core.ServiceAccount, pod *core.Pod, secret *core.Secret, expirationSeconds, warnafter int64, audience []string) (*jwt.Claims, interface{})

func JWTTokenAuthenticator Uses

func JWTTokenAuthenticator(iss string, keys []interface{}, implicitAuds authenticator.Audiences, validator Validator) authenticator.Token

JWTTokenAuthenticator authenticates tokens as JWT tokens produced by JWTTokenGenerator Token signatures are verified using each of the given public keys until one works (allowing key rotation) If lookup is true, the service account and secret referenced as claims inside the token are retrieved and verified with the provided ServiceAccountTokenGetter

func LegacyClaims Uses

func LegacyClaims(serviceAccount v1.ServiceAccount, secret v1.Secret) (*jwt.Claims, interface{})

func RegisterMetrics Uses

func RegisterMetrics()

type OpenIDMetadata Uses

type OpenIDMetadata struct {
    ConfigJSON       []byte
    PublicKeysetJSON []byte

OpenIDMetadata contains the pre-rendered responses for OIDC discovery endpoints.

func NewOpenIDMetadata Uses

func NewOpenIDMetadata(issuerURL, jwksURI, defaultExternalAddress string, pubKeys []interface{}) (*OpenIDMetadata, error)

NewOpenIDMetadata returns the pre-rendered JSON responses for the OIDC discovery endpoints, or an error if they could not be constructed. Callers should note that this function may perform additional validation on inputs that is not backwards-compatible with all command-line validation. The recommendation is to log the error and skip installing the OIDC discovery endpoints.

type ServiceAccountTokenGetter Uses

type ServiceAccountTokenGetter interface {
    GetServiceAccount(namespace, name string) (*v1.ServiceAccount, error)
    GetPod(namespace, name string) (*v1.Pod, error)
    GetSecret(namespace, name string) (*v1.Secret, error)

ServiceAccountTokenGetter defines functions to retrieve a named service account and secret

type TokenGenerator Uses

type TokenGenerator interface {
    // GenerateToken generates a token which will identify the given
    // ServiceAccount. privateClaims is an interface that will be
    // serialized into the JWT payload JSON encoding at the root level of
    // the payload object. Public claims take precedent over private
    // claims i.e. if both claims and privateClaims have an "exp" field,
    // the value in claims will be used.
    GenerateToken(claims *jwt.Claims, privateClaims interface{}) (string, error)

func JWTTokenGenerator Uses

func JWTTokenGenerator(iss string, privateKey interface{}) (TokenGenerator, error)

JWTTokenGenerator returns a TokenGenerator that generates signed JWT tokens, using the given privateKey. privateKey is a PEM-encoded byte array of a private RSA key.

type Validator Uses

type Validator interface {
    // Validate validates a token and returns user information or an error.
    // Validator can assume that the issuer and signature of a token are already
    // verified when this function is called.
    Validate(ctx context.Context, tokenData string, public *jwt.Claims, private interface{}) (*apiserverserviceaccount.ServiceAccountInfo, error)
    // NewPrivateClaims returns a struct that the authenticator should
    // deserialize the JWT payload into. The authenticator may then pass this
    // struct back to the Validator as the 'private' argument to a Validate()
    // call. This struct should contain fields for any private claims that the
    // Validator requires to validate the JWT.
    NewPrivateClaims() interface{}

Validator is called by the JWT token authenticator to apply domain specific validation to a token and extract user information.

func NewLegacyValidator Uses

func NewLegacyValidator(lookup bool, getter ServiceAccountTokenGetter) Validator

func NewValidator Uses

func NewValidator(getter ServiceAccountTokenGetter) Validator
