运行sequelize迁移时出现错误getaddrinfo ENOTFOUND db

Question

yarn sequelize db:migrate我正在使用 docker-compose，当我尝试在控制台中运行时出现以下错误：

“已加载配置文件“src/config/database.js”。错误：getaddrinfo ENOTFOUND db”

一切正常，但我无法运行我的迁移。

Dockerfile

FROM node:alpine

WORKDIR /usr/app
COPY package.json yarn.lock ./

RUN yarn

COPY . .

EXPOSE 3000
CMD ["yarn", "dev"]

Docker-compose.yml

version: '3'

services:
  api:
    container_name: api
    build: .
    ports:
      - '3000:3000'
    command: yarn dev
    volumes:
      - .:/usr/app
    links:
      - db

  db:
    container_name: db
    image: mysql:5.7
    volumes:
      - ./data:/mysql/db
    ports:
      - '3306:3306'
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: be_db
      MYSQL_USER: root
      MYSQL_PASSWORD: password

.env

# Database Variables
DB_HOST=db
DB_USER=root
DB_PASS=password
DB_NAME=be_db
DB_PORT:3306

/src/config/database.js

require('dotenv').config();

module.exports = {
  dialect: 'mysql',
  host: process.env.DB_HOST,
  username: process.env.DB_USER,
  password: process.env.DB_PASS,
  database: process.env.DB_NAME,
  define: {
    timestamps: false,
    underscored: true,
    underscoredAll: true,
  },
};

OBS：如果我切换DB_HOST=db到DB_HOST=localhost我可以运行我的迁移，但是我的容器会弹出此错误：

code: 'ECONNREFUSED',
api    |     syscall: 'connect',
api    |     address: '127.0.0.1',
api    |     port: 3306,
api    |     fatal: true

好的，我只需将端口和主机分成单独的字段：

\n

"development": {\n    "username": "postgres",\n    "password": "postgres",\n    "database": "postgres",\n    "host": "localhost",\n    "port": "5434",\n    "dialect": "postgres"\n  },\n

\n\n

docker-compose我也有同样的问题sequelize-cli

\n

  node:\n    build:\n      context: ./node\n      target: dev\n    volumes:\n      - ./node/src:/app/src\n      - ./node/private:/app/private\n    ports:\n      - 3111:3000\n    command: npm run dev\n    environment:\n      - NODE_ENV=development\n    env_file:\n      - ./node/.env\n    depends_on:\n      - db\n\n  db:\n    image: postgres:12-alpine\n    ports:\n      - 5434:5432\n    environment:\n      - POSTGRES_HOST_AUTH_METHOD=trust\n      - POSTGRES_USER=postgres\n      - POSTGRES_PASSWORD=postgres\n      - POSTGRES_DB=postgres\n

\n

  "development": {\n    "username": "postgres",\n    "password": "postgres",\n    "database": "postgres",\n    "host": "localhost:5434",\n    "dialect": "postgres"\n  }\n

当我跑步时\xe2\x9d\xaf npx sequelize-cli db:migrate

\n

我收到以下错误\n：

\n

Sequelize CLI [Node: 15.2.1, CLI: 6.2.0, ORM: 6.3.5]\n\nLoaded configuration file "config/config.json".\nUsing environment "development".\n\nERROR: getaddrinfo ENOTFOUND localhost:5434\n

\n

它适用于以下命令，这更多的是一种解决方法

\n

\xe2\x9d\xaf npx sequelize-cli db:migrate --url \'postgres://postgres:postgres@localhost:5434/postgres\'\n\nSequelize CLI [Node: 15.2.1, CLI: 6.2.0, ORM: 6.3.5]\n\nParsed url postgres://postgres:*****@localhost:5434/postgres\nNo migrations were executed, database schema was already up to date.\n
