Question

我正在尝试使用docker-compose.yml设置一个用于WordPress开发的docker容器，如下所示：

version: '3'
services:
  db:
    image: mysql:5.7
    volumes:
      - data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: wordpress
      MYSQL_USER: root
  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - 8080:80
      - 443:443
    volumes:
      - ./data:/data # Required if importing an existing database
      - ./:/var/www/html # Theme development
    environment:
      WORDPRESS_DB_NAME: wordpress
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: root
      WORDPRESS_DB_PASSWORD: root
  phpmyadmin:
    depends_on:
      - db
    image: phpmyadmin/phpmyadmin
    environment:
      MYSQL_ROOT_PASSWORD: root
    ports:
      - 3306:80
volumes:
  data: {}

我得到这样的错误：

wordpress_1   | Warning: mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed: Name or service not known in - on line 22
wordpress_1   | 
wordpress_1   | Warning: mysqli::mysqli(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known in - on line 22
wordpress_1   | 
wordpress_1   | MySQL Connection Error: (2002) php_network_getaddresses: getaddrinfo failed: Name or service not known

我尝试清理我的图像和容器，但没有运气。知道为什么会这样吗？

Answer 1

尝试为wordpress和phpmyadmin提供链接选项。

links:
  - db:mysql

修改：检查this问题。将mysql添加到db。我不知道如果这个解决了，我必须在我以后回家时尝试一下。

WordPress docker compose不会启动mysql
