官网示例：

安装wordpress

version: "2"　　　　　　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: wordpressvolumes:    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。

示例一，安装haproxy+nginx

docker-compose.yml

haproxy目录执行docker-compose up -d ,完成后通过docker ps -a 查看
