Node SDK v2 Gateway не может подключиться к одноранговому узлу

0 голосов
/ 06 августа 2020

У меня есть работающий тест tnet с externalTLS в кластере Kubernetes. Настройка работает, так как я могу безупречно использовать интерфейс командной строки для вызова и запроса цепного кода.

Однако в Node я могу зарегистрировать личность, но не могу успешно выполнить gateway.connect(...). Сообщения об ошибках от клиента и однорангового узла мне ничего не говорят.

Итак, что-то достигает однорангового узла. Я просто не понимаю, почему соединение не может быть установлено.

Контрольный список:

  • Приведено tlscacert org1 в соединении. json? проверить
  • Зарегистрирован идентификатор TLS для клиента? проверить
  • Предоставлял ли шлюз идентификатор TLS? проверить
  • Пробовали httpOptions.verify = false в соединении. json для однорангового узла? проверить
  • Пробовали оба, user и ${user}-tls в качестве идентификатора шлюза? проверить

Есть идеи?

Проблема была в сертификате TLS моих сверстников. С помощью export GRPC_VERBOSITY=DEBUG и export GRPC_TRACE=all я получил от моего клиента следующее:

2020-08-10T16:13:52.283Z | subchannel | x.x.x.x:30151 connection closed with error Hostname/IP does not match certificate's altnames: Host: worker2.example.com. is not in the cert's altnames: DNS:org1-peer1
