mysql - NodeJS和Sequelize在docker compose中无法连接到MySQL

Question

我有一个非常相似的问题出现在这里:
Node.js connect to MySQL Docker container ECONNREFUSED

但不幸的是，提议的解决方案不起作用。
我有一个带有 Typescript(可能不相关)、Sequelize 和 MySQL 数据库的 NodeJS 项目。
我已经设置了一个带有脚本的 docker-compose 文件，这些脚本基于 github 的脚本来设置它们并启动它们来统治它们。
script/setup 只是为数据库创建卷并启动它:

...
docker-compose down
docker volume create --name=tournaments-data
docker-compose up -d tournaments-db

完成后，我运行 script/start ，它正在启动 Web 应用程序:

...
docker-compose up web

version: '3'

volumes:
  tournaments-data:

services:
  base: &app_base
    build:
      context: .
      dockerfile: Dockerfile
    depends_on:
      - tournaments-db

  web:
    <<: *app_base
    command: npm run watch-debug
    volumes:
      - ./dist:/usr/src/app/dist
    ports:
      - 3000:3000
      - 5858:5858

  tournaments-db:
    image: mysql:5.6.45
    command: --default-authentication-plugin=mysql_native_password
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: 'whatever'
      MYSQL_DATABASE: tournaments
    expose:
      - '3307'
    ports:
      - '3307:3306'
    volumes:
      - tournaments-data:/var/lib/mysql

我的 Sequelize 配置如下所示:

...
development: {
    username: 'root',
    password: 'whatever',
    database: 'tournaments',
    host: 'tournaments-db',
    port: '3307',
    dialect: 'mysql',
    operatorsAliases: false,
  }
...

所有容器都正确启动，我能够使用以下命令从命令行成功地将 连接到 MySQL 容器:mysql -uroot -p -h 127.0.0.1 -P 3307 --protocol=tcp 和 JetBrains Datagrip。

看起来 NodeJS 应用程序似乎无法正确连接到 mysql 数据库，因为我收到以下错误:

Unable to connect to the database: ConnectionRefusedError [SequelizeConnectionRefusedError]: connect ECONNREFUSED 127.0.0.1:3306

我尝试从所有 IP(而不仅仅是 localhost)授予 root 访问权限，但这也不起作用。
还认为这是 docker-compose 的网络问题，所以我确认它们在同一个网络上(它们是)，还尝试通过 docker-compose 为它们创建不同的网络，但这也不起作用。

有没有人有任何想法可能会丢失？由于我可以从外部连接到 mysql 实例，因此我认为我缺少一些配置或类似的配置，但是在查看了很多建议的解决方案后，没有用。

P.S 由于业务限制，MySQL 版本被锁定，所以我无法升级/使用其他版本

Answer 1

所以，我终于弄清楚出了什么问题。
我解决了一个问题，但导致了另一个问题。基本上我创建的 Sequelize 实例没有通过主机 + 端口配置，所以它使用了默认的 127.0.0.1:3306
本质上是这样的:

export const sequelize = new Sequelize({
  database: config.database,
  username: config.username,
  password: config.password,
  models: [path.join(__dirname, '/models')],
  dialect: config.dialect,
});

取而代之的是:

export const sequelize = new Sequelize({
  host: config.host,
  port: config.port,
  database: config.database,
  username: config.username,
  password: config.password,
  models: [path.join(__dirname, '/models')],
  dialect: config.dialect,
});


So config was correct, but I was just not using it properly in my code.
