Answer 1

services:

  wordpress:
    image: wordpress
    ports:
      - "80"
    environment:
      WORDPRESS_DB_HOST: mysql
      WORDPRESS_DB_PASSWORD: root
    networks:
      - my-bridge
    
  mysql:
    image: mysql
    environment:
      MYSQL_ROOT_PASSWD: root
      MYSQL_DATABASE: wordpress
    volumes:
      - mysql-data:/var/bib/mysql
    networks: 
      - my-bridge
  
#  volumes:这个应该放到 wordpress或是mysql下
#    mysql-data:

# 网络和services同级别
networks: 
  my-bridge:
    drive: bridge
