如何修复 docker-compose.yml 中的续集“npx Sequelize-cli db:migrate”？

Question

我面对

Sequelize CLI [节点：21.7.1，CLI：6.6.2，ORM：6.37.1] | |已加载配置文件“database/config/config.json”。 |使用环境“生产”。 |错误：用户“root”@“172.21.0.3”的访问被拒绝（使用密码：YES）

设置

.env.production

并应用命令

sudo docker compose --env-file ./.env.production up --build

。

这是我的

docker-compose.yml

：

version: '3.8'

networks:
  common:
    driver: bridge

services:
  db:
    networks: 
      - common
    container_name: database
    volumes:
      - mysql_data:/var/lib/mysql
    restart: on-failure
    ports:
      - 3306:3306
    build:
      context: .
      dockerfile: Dockerfile.mysql
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-p$MYSQL_ROOT_PASSWORD"]
      interval: 1s
      retries: 120
      
  adminer:
    image: adminer
    restart: always
    container_name: adminer-g-database
    links:
      - db:db
    ports:
      - 8080:8080
    
  app:
    networks:
      - common
    build:
      context: .
      dockerfile: Dockerfile.app
    container_name: g-app
    restart: always
    links:
      - db:db
    ports:
      - 3000:3000
    depends_on:
      db: 
        condition: service_healthy

    command: sh -c "npx sequelize-cli db:migrate && npm install && npm run build && npm start"
    volumes:
      - .:/usr/src/app
      - /usr/src/app/node_modules

volumes:
  mysql_data:
    driver: local

这是我的

Dockerfile

的

Docker.mysql

：

#Create MySQL
FROM mysql

LABEL name=gel

EXPOSE 3306

这是 nextJS 应用程序，尝试通过运行 mysql 容器并应用sequelize 迁移命令来构建应用程序。预先感谢

这是一个可以帮助您入门的最小工作设置。

migrations

文件夹对我来说是空的。

🗎

config.json

（我已将其设置为开发环境，但一旦您可以使用它，您就可以更改为生产环境。）

{
    "development": {
      "username": "root",
      "password": "password",
      "database": "mysql",
      "host": "db",

    }
  }

🗎

docker-compose.yml

version: '3.8'

services:
  db:
    image: mysql
    restart: on-failure
    environment:
      MYSQL_ROOT_PASSWORD: password
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-p$MYSQL_ROOT_PASSWORD"]

🗎

Dockerfile.app

FROM node:16

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install

COPY . .

RUN npm run build

CMD ["sh", "-c", "npx sequelize-cli db:migrate && npm start"]

🗎

package.json

（

start

脚本只是一个占位符。）
