在您将此问题标记为重复之前,请注意我确实阅读了其他答案,但这并没有解决我的问题.

我有一个Docker撰写文件,包含两个服务:

version: "3"
services:
  mysql:
    image: mysql:5.7
    environment:
      MYSQL_HOST: localhost
      MYSQL_DATABASE: mydb
      MYSQL_USER: mysql
      MYSQL_PASSWORD: 1234
      MYSQL_ROOT_PASSWORD: root
    ports:
      - "3307:3306"
    expose:
      - 3307
    volumes:
      - /var/lib/mysql
      - ./mysql/migrations:/docker-entrypoint-initdb.d
    restart: unless-stopped
  web:
    build:
      context: .
      dockerfile: web/Dockerfile
    volumes:
      - ./:/web
    ports:
      - "3000:3000"
    environment:
      NODE_ENV: development
      PORT: 3000
    links:
      - mysql:mysql
    depends_on:
      - mysql
    expose:
      - 3000
    command: ["./wait-for-it.sh", "mysql:3307"]

/网络/ Dockerfile:

FROM node:6.11.1

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

COPY package.json /usr/src/app/
RUN npm install

COPY . /usr/src/app …

使用sequelize作为orm后端对节点postgres数据库进行docker化时出现以下错误

未处理的拒绝 SequelizeConnectionRefusedError：连接 ECONNREFUSED 127.0.0.1:5432 app_1 | 在connection.connect.err（/home/app/node_modules/sequelize/lib/dialects/postgres/connection-manager.js:170:24）

这些代码行似乎是罪魁祸首，docker 不应该连接这些凭据，因为这是我本地的。

if (process.env.NODE_ENV === "production") {
  var sequelize = new Sequelize(process.env.DATABASE_URL);
} else {
  // docker is looking at these credentials..... when it should not
  var sequelize = new Sequelize("elifullstack", "eli", "", {
    host: "127.0.0.1",
    dialect: "postgres",
    pool: {
      max: 100,
      min: 0,
      idle: 200000,
      // @note https://github.com/sequelize/sequelize/issues/8133#issuecomment-359993057
      acquire: 1000000,
    },
  });
}

docker-compose.yml

# docker-compose.yml
version: "3"
services:
  app:
    build: ./server
    depends_on:
      - database
    ports:
      - 5000:5000
    environment:
      # database …
