官网示例：
安装wordpress
version: "2" #这里写3会报错 services: db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: wordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress wordpress: depends_on: - db image: wordpress:latest ports: - "8001:80" restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress volumes: db_data:
运行 docker-compose up -d Compose 就会拉取镜像再创建我们所需要的镜像，然后启动 wordpress 和数据库容器。 接着浏览器访问 127.0.0.1:8000 端口就能看到 WordPress 安装界面了。
其他示例
示例一，安装haproxy+nginx
