Functions

func InternalIsServiceAccountToken

func InternalIsServiceAccountToken(secret *api.Secret, sa *api.ServiceAccount) bool

TODO: remove the duplicate code InternalIsServiceAccountToken returns true if the secret is a valid api token for the service account

func IsServiceAccountToken

func IsServiceAccountToken(secret *v1.Secret, sa *v1.ServiceAccount) bool

IsServiceAccountToken returns true if the secret is a valid api token for the service account

func JWTTokenAuthenticator

func JWTTokenAuthenticator(keys []interface{}, lookup bool, getter ServiceAccountTokenGetter) 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 ReadPrivateKey

func ReadPrivateKey(file string) (interface{}, error)

ReadPrivateKey is a helper function for reading a private key from a PEM-encoded file

func ReadPublicKeys

func ReadPublicKeys(file string) ([]interface{}, error)

ReadPublicKeys is a helper function for reading an array of rsa.PublicKey or ecdsa.PublicKey from a PEM-encoded file. Reads public keys from both public and private key files.

func ReadPublicKeysFromPEM

func ReadPublicKeysFromPEM(data []byte) ([]interface{}, error)

ReadPublicKeysFromPEM is a helper function for reading an array of rsa.PublicKey or ecdsa.PublicKey from a PEM-encoded byte array. Reads public keys from both public and private key files.

func UserInfo

func UserInfo(namespace, name, uid string) user.Info

UserInfo returns a user.Info interface for the given namespace, service account name and UID

Types

type ServiceAccountTokenGetter

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

ServiceAccountTokenGetter defines functions to retrieve a named service account and secret

type TokenGenerator

type TokenGenerator interface {
	// GenerateToken generates a token which will identify the given ServiceAccount.
	// The returned token will be stored in the given (and yet-unpersisted) Secret.
	GenerateToken(serviceAccount v1.ServiceAccount, secret v1.Secret) (string, error)
}

func JWTTokenGenerator

func JWTTokenGenerator(privateKey interface{}) TokenGenerator

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. JWTTokenAuthenticator()
