Образ Docker Nginx запускается, но завершается с ошибкой «порт уже используется»

Question

У меня есть докер-контейнер с alphine-nginx изображением. Я помещаю 5 файлов конфигурации Nginx в этот контейнер, но он не работает и завершается ошибкой с «портом, который уже используется» внутри контейнера. Каждый файл конфигурации содержит свой порт, но он не запускается при запуске.

error.log имеет:

Как я вижу, что-то запускает Nginx, но как проверить, что это?

Docker ps:

Answer 1

У вас есть процесс id (PID) процесса, который занял порт. Вы можете использовать ps -p 9 -o comm=, чтобы получить командную строку для этого процесса.

Я думаю, что это докер. В этом случае попробуйте docker ps, чтобы получить список запущенных Docker-контейнеров.

И вы можете просто убить этот процесс с помощью kill -9 9.

Обновлено: У меня естьпопытался запустить контейнер по docker run nginx:1.17.4-alpine и не имеет проблем. Если вы создаете собственный образ или используете дополнительные настройки или конфигурации, которые отличаются от настроек по умолчанию - вам необходимо описать их.
