应用程序需要预先运行db。为 WordPress 服务添加 depends_on 值，这将确保数据库容器在 WordPress 容器之前启动。容器内的 MySQL 服务应该很快启动。

version: '3.1'

services:

  wordpress:
    image: wordpress
    restart: always
    depends_on:
      - db
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: exampleuser
      WORDPRESS_DB_PASSWORD: examplepass
      WORDPRESS_DB_NAME: exampledb

  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_DATABASE: exampledb
      MYSQL_USER: exampleuser
      MYSQL_PASSWORD: examplepass
      MYSQL_RANDOM_ROOT_PASSWORD: '1'
