Связь между микросервисами с помощью docker -compose

/ 19 июня 2020

У меня есть три микросервиса с базами данных MongoDB. Я пытаюсь связать контейнер микросервиса оценки с другими контейнерами, такими как player и game. Потому что для запроса REST API мой метод POST в контроллере очков репозиторием игрока и репозиторием игры проверяет, существуют ли игрок и игра, а затем публикует новый счет для существующего проигрывателя и игры. Я знаю, что Docker использует сеть по умолчанию для моих контейнеров и связывает их вместе, но когда я использую Postman для службы оценки по URL-адресу 192.168.99.100:8080/score POST-запроса, он не работает и показывает мне ошибку 500. в docker shell У меня нет ошибок и он хорошо работает для других сервисов, но когда я использую POST-запрос в Postman после этого В оболочке Docker у меня есть:

Я пробовал работать в сети docker -compose Но это не работает. Я проверил эти сайты: https://docs.docker.com/compose/networking/ и так далее, любые ссылки на эту и Docker документацию, но я не смог найти никакого решения. для уровня приложения микросервисов у меня нет никаких проблем, и все микросервисы работают хорошо, но на уровне Docker у меня есть проблемы, и служба оценки не работает.

внутри контейнера оценки, когда я это сделаю ping к контейнеру игрока и контейнеру игры, все в порядке. Не знаю, в чем моя ошибка.
