docker

в моем docker -компонентном файле: 

version: "3"

services:
  server:
    image: asubscriber/eshop:1.0.1
    build: .
    ports:
      - 8090:8090

  1. Запустите мое приложение (Spring boot) из консоли следующим образом:

    java -jar build / libs / eshop-1.0.1.jar eshop-1.0.1.jar

Выполнить успешно. И успех на http запрос. Вот лог:

Ницца. Это нормально работает. Успешно отправьте запрос POST http.

Теперь я запускаю ЖЕ МОЕ приложение от docker compose

docker - составить

Успешно запустить приложение , Но если я хочу создать http-запрос, я получаю сообщение об ошибке:

добавьте это к вашей службе в docker -компонентном файле (только сетевая часть) 

version: "3"

services:
  server:
    image: asubscriber/eshop:1.0.1
    build:
      context: .

    network_mode: "host"

    expose:
        - 9080

Это ответ, чтобы просто заставить его работать, лучше прочитать это , как отметил Сергей Петунин в комментариях выше.
