示例1: waitForToken
// waitForToken uses `cmd.Until` to wait for the service account controller to fulfill the token request
func waitForToken(token *api.Secret, serviceAccount *api.ServiceAccount, timeout time.Duration, client unversioned.SecretsInterface) (*api.Secret, error) {
// there is no provided rounding function, so we use Round(x) === Floor(x + 0.5)
timeoutSeconds := int64(math.Floor(timeout.Seconds() + 0.5))
options := api.ListOptions{
FieldSelector: fields.SelectorFromSet(fields.Set(map[string]string{"metadata.name": token.Name})),
Watch: true,
ResourceVersion: token.ResourceVersion,
TimeoutSeconds: &timeoutSeconds,
}
watcher, err := client.Watch(options)
if err != nil {
return nil, fmt.Errorf("could not begin watch for token: %v", err)
