Невозможно подключить хром

Question

Я занимаюсь разработкой, которая требует некоторого взаимодействия с Google Chrome.Я запускаю свое приложение внутри док-контейнера.Пока он находится вне докера, я могу подключиться к браузеру Chrome, но когда он находится внутри докера, я получаю сообщение об ошибке типа

Answer 1

Вы можете использовать флаг --add-host с командой docker run при запуске контейнера приложения:

docker run --add-host="chrome:127.0.0.1" <the rest of the command>

Затем вы можете получить доступ к локально запущенному экземпляру Chrome с помощью chromeИмя хоста.Конечно, все это требует, чтобы используемый вами порт был фактически открыт (я полагаю, это так, поскольку приложение работает вне контейнера).
