docker-compose文件的简介及使用

一、docker-compose 文件整合多个项目配置

version: '3.8'

services:
  # MySQL 数据库服务
  mysql:
    image: mysql:5.7  # 使用官方的 MySQL 镜像，版本为 5.7
    container_name: my_mysql
    environment:
      TZ: Asia/Shanghai
      MYSQL_ROOT_PASSWORD: root_password  # 设置 root 用户的密码
      MYSQL_DATABASE: mydb  # 创建一个名为 mydb 的数据库
      MYSQL_USER: myuser  # 创建一个名为 myuser 的用户
      MYSQL_PASSWORD: mypassword  # 设置 myuser 用户的密码
    volumes:
      - "./mysql/data:/var/lib/mysql"
      - "./mysql/conf:/etc/mysql/confi.d"
      - "./mysql/init:/docker-entrypoint-initdb.d"
    ports:
      - "3306:3306"  # 将宿主机的 3306 端口映射到容器的 3306 端口
    networks:
      - my_net
aipro:
  build:			# 根据Dockerfile文件构建镜像
    context: .
    dockerfile: Dockerfile
  container_name: aipro
  ports:
      - "8080:8080" # 将宿主机的 8080 端口映射到容器的 8080 端口（根据你的后端应用配置调整）
  networks:
      - my_net
  depends_on:
      - my_mysql  # 确保 MySQL 服务先启动
  # Nginx 服务，用于反向代理前端和后端
nginx:
    image: nginx:latest  # 使用官方的 Nginx 镜像，版本为 latest
    container_name: my_nginx
    volumes:
      - "./nginx/nginx.conf:/etc/nginx/nginx.conf"  # 使用自定义的 Nginx 配置文件
      - "./nginx/frontend/dist:/usr/share/nginx/html"  # 将前端应用的静态文件映射到 Nginx 的默认根目录
    ports:
      - "80:80"  # 将宿主机的 80 端口映射到容器的 80 端口
    depends_on:
      - aipro  # 确保后端服务先启动（如果 Nginx 需要代理到后端）
    networks:
      - my_net
networks:
  my_net:
    name: aipro
