mysql - Docker 中的 phpMyAdmin 错误 "No address associated with hostname"？

Question

我正在尝试将我的 Laravel 项目容器化。我的 docker-compose.yml 中有以下服务

1. laravel_app
2. 数据库
3. nginx
4. phpmyadmin

除 PHPMyAdmin 外，所有这些都运行良好。它已构建并确实为 phpMyAdmin 登录页面提供服务，但在输入凭据时出现以下错误。

Cannot log in to the MySQL server

mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: No address associated with hostname

mysqli::real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No address associated with hostname

这是我的 docker-compose.yml 片段，其中包括我的数据库服务和 phpmyadmin 服务

#The Database

  database:
    container_name: mysql_database
    image: mysql:5.7
    volumes:
      - dbdata:/var/lib/mysql
    environment:
      - "MYSQL_DATABASE=dev-db"
      - "MYSQL_USER=phpmyadmin"
      - "MYSQL_PASSWORD=phpmyadmin"
      - "MYSQL_ROOT_PASSWORD=123456"
    ports:
      - 8991:3306


#PHPMyAdmin Service
  phpmyadmin:
    container_name: phpmyadmin
    image: phpmyadmin/phpmyadmin
    ports:
    - "8992:80"
    depends_on: 
      - database
    environment:
      - "PMA_HOST:database"
      - "MYSQL_USER:phpmyadmin"
      - "MYSQL_PASSWORD:phpmyadmin"
      - "MYSQL_ROOT_PASSWORD:123456"
      - "UPLOAD_LIMIT:3000000000"


# redis

  cache:
    image: redis:3.0-alpine

为此，您至少需要创建一个桥接网络并将 phpmyadmin 和您的数据库连接到它。

像这样的东西应该可以工作:

version: "3"
volumes:
  dbdata:
networks:
  backend:
    driver: bridge
services:
  database:
    container_name: mysql_database
    image: mysql:5.7
    volumes:
      - dbdata:/var/lib/mysql
    environment:
      - "MYSQL_DATABASE=dev-db"
      - "MYSQL_USER=phpmyadmin"
      - "MYSQL_PASSWORD=phpmyadmin"
      - "MYSQL_ROOT_PASSWORD=123456"
    ports:
      - 8991:3306
    networks:
      - backend

  phpmyadmin:
    container_name: phpmyadmin
    image: phpmyadmin/phpmyadmin
    ports:
      - "8992:80"
    depends_on:
      - database
    environment:
      - "PMA_HOST=database"
      - "MYSQL_USER=phpmyadmin"
      - "MYSQL_PASSWORD=phpmyadmin"
      - "MYSQL_ROOT_PASSWORD=123456"
      - "UPLOAD_LIMIT=3000000000"
    networks:
      - backend
  

另外我不建议暴露数据库端口
