Types

type TokenGetter

type TokenGetter struct {
	// contains filtered or unexported fields
}

func NewTokenGetter

func NewTokenGetter(client corev1.ServiceAccountsGetter, options ...TokenGetterOption) *TokenGetter

func (*TokenGetter) Delete

func (*TokenGetter) Get

func (t *TokenGetter) Get(ctx context.Context, key types.NamespacedName) (string, error)

Get returns a token from the cache if available and not expiring, otherwise creates a new token

type TokenGetterOption

type TokenGetterOption func(*TokenGetter)

func WithExpirationDuration

func WithExpirationDuration(expirationDuration time.Duration) TokenGetterOption

type TokenInjectingRoundTripper

type TokenInjectingRoundTripper struct {
	Tripper     http.RoundTripper
	TokenGetter *TokenGetter
	Key         types.NamespacedName
}

func (*TokenInjectingRoundTripper) RoundTrip

func (tt *TokenInjectingRoundTripper) RoundTrip(req *http.Request) (*http.Response, error)
