func IsServiceAccountToken

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

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

func JWTTokenAuthenticator

func JWTTokenAuthenticator(keys []*rsa.PublicKey, 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 MakeGroupNames

func MakeGroupNames(namespace, name string) []string

MakeGroupNames generates service account group names for the given namespace and ServiceAccount name

func MakeNamespaceGroupName

func MakeNamespaceGroupName(namespace string) string

MakeNamespaceGroupName returns the name of the group all service accounts in the namespace are included in

func MakeUsername

func MakeUsername(namespace, name string) string

MakeUsername generates a username from the given namespace and ServiceAccount name. The resulting username can be passed to SplitUsername to extract the original namespace and ServiceAccount name.

func ReadPrivateKey

func ReadPrivateKey(file string) (*rsa.PrivateKey, error)

ReadPrivateKey is a helper function for reading an rsa.PrivateKey from a PEM-encoded file

func ReadPublicKey

func ReadPublicKey(file string) (*rsa.PublicKey, error)

ReadPublicKey is a helper function for reading an rsa.PublicKey from a PEM-encoded file Reads public keys from both public and private key files

func SplitUsername

func SplitUsername(username string) (string, string, error)

SplitUsername returns the namespace and ServiceAccount name embedded in the given username, or an error if the username is not a valid name produced by MakeUsername

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) (*api.ServiceAccount, error)
	GetSecret(namespace, name string) (*api.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 api.ServiceAccount, secret api.Secret) (string, error)
}

func JWTTokenGenerator

func JWTTokenGenerator(key *rsa.PrivateKey) 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()
