Описание

• Инициализирует MongoDB репликацию в новом развертывании.
• Проверяет имя репликации для существующих развертываний.
• Возможно продвинутое (пере)конфигурирование членов репликации (см. примеры).
• Инициализируйте репликацию перед добавлением пользователей в соответствии с лучшими практиками (https://www.mongodb.com/docs/manual/tutorial/deploy-replica-set-with-keyfile-access-control/).
