mysql - Wordpress 不适用于 docker compose

Question

这是我的 docker-compose.yml

version: '2'

services:

 wordpress:
    image: wordpress:4.6.1-php5.6-apache
    container_name: wordpress
    volumes:
         - ./projects/:/home/docker/
    working_dir: /home/docker/
    ports:
         - "8000:80"
    environment:
        WORDPRESS_DB_PASSWORD: secret
    links:
        - database-mysql

 database-mysql:
   image: mysql:5.7
   container_name: mysqldb
   ports:
     - "3306:3306"
   volumes:
     - ./backups/mysqldb/:/var/lib/mysql/
   environment:
     MYSQL_ROOT_PASSWORD: secret
     MYSQL_DATABASE: wordpress

 phpmyadmin:
   image: phpmyadmin/phpmyadmin:latest
   container_name: phpmyadmin
   ports:
     - "8080:80"
   environment:
     PMA_USER: root
     PMA_PASSWORD: secret
     PMA_HOST: database-mysql
   links:
     - database-mysql

当我运行:docker-compose up时，日志错误显示:

MySQL 连接错误:(2002) php_network_getaddresses:getaddrinfo 失败:名称或服务未知

警告:mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed: Name or service not known in - on line 19

警告:mysqli::mysqli(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known in - on line 19

2016-11-11 04:14:33,648 INFO 成功:nginx 进入 RUNNING 状态，进程已停留 > 超过 1 秒 (startsecs)

我做错了什么？

评论太长了，所以我创建了另一个答案
尝试这个并等待 2 分钟，然后访问 localhost:8000

version: '2'

services:
   db:
     image: mysql:5.7
     volumes:

     environment:
       MYSQL_ROOT_PASSWORD: wordpress
       MYSQL_DATABASE: wordpress

       WORDPRESS_DB_PASSWORD: wordpress

   phpmyadmin:
