可以从其他容器从本地主机访问泊坞窗容器但不

Question

我有一个使用MySQL的应用程序，Nest.js的角度为DB，背部和前。我已经成功地得到巢传达给MySQL的容器NAD（我想）角与鸟巢，但是当我尝试从浏览器访问前端，它说，该网站不能被达到，或服务器没有回答如果我做邮差从到后端的请求。我已经暴露和分配端口的端口，但它无法正常工作。

我跑docker-compose up --build，浏览localhost:4200或发送到localhost:3000要求什么，我从浏览器得到的是localhost didn’t send any data. ERR_EMPTY_RESPONSE在Chrome。

这是MI泊坞窗，compose.yml文件：

version: '3'

services:

# MySQL
  db:
    image: mysql:5.7
    command: --default-authentication-plugin=mysql_native_password
    ports:
      - "3306:3306"
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
      MYSQL_DATABASE: ${MYSQL_DATABASE}
      MYSQL_USER: ${MYSQL_USER}
      MYSQL_PASSWORD: ${MYSQL_PASSWORD}

# Nest.js Backend
  server:
    build: ./backend
    expose:
      - 3000
    ports:
      - "3000:3000"
    depends_on:
      - db
    links:
      - db
    volumes:
      - ./backend/src:/srv/app/bk-god/src

# Angular 6 Frontend
  client:
    build: ./frontend
    expose:
      - 4200
    ports:
      - "4200:4200"
    volumes:
      - ./frontend/src:/srv/app/fr-god/src
      - ./frontend/public:/srv/app/fr-god/public
    links:
      - server

这是我Dockerfile每个文件夹[唯一的区别是后端运行的丝线行进开始了：dev]：

FROM node:8.15.0-alpine

RUN mkdir -p /srv/app/fr-god
WORKDIR /srv/app/fr-god

COPY package.json /srv/app/fr-god
COPY yarn.lock /srv/app/fr-god

RUN yarn

COPY . /srv/app/fr-god
CMD ["yarn", "start"]

PS：MySQL是通过控制台和GUI访问，指向localhost:3306。

这是docker ps输出：

阅读this文件让我觉得，你的“暴露”的声明可能会重挫你的“端口”的声明。尝试删除“暴露”的声明并重装容器。这应该可以解决您的问题。
