是否可以使用 docker 在 phpMyAdmin 中拥有多个默认的 mysql 服务器

Question

我正在尝试使用带有两台 MySQL 服务器和一台 phpMyAdmin 服务器的 Docker 构建环境，以便在开发过程中轻松分析数据。 我的 docker-compose.yml 看起来像这样。

version: "3.9"
  services:
    database1:
      container_name: Database1
      image: mysql:8.0.28
      command: --default-authentication-plugin=mysql_native_password
      restart: always
      environment:
        MYSQL_DATABASE: database1
        MYSQL_ROOT_PASSWORD: somepassword
        MYSQL_USER: databaseuser1
        MYSQL_PASSWORD: databaseuser1
      ports:
        - "3306:3306"
      volumes:
        - database-volume:/var/lib/mysql
      networks: 
        - my_network
      database2:
      container_name: Database2
      image: mysql:8.0.28
      command: --default-authentication-plugin=mysql_native_password
      restart: always
      environment:
        MYSQL_DATABASE: database2
        MYSQL_ROOT_PASSWORD: somepassword
        MYSQL_USER: databaseuser2
        MYSQL_PASSWORD: databaseuser2
      ports:
        - "3307:3306"
      volumes:
        - second-database-volume:/var/lib/mysql
      networks: 
        - my_network      
    phpmyadmin:
      container_name: PhpMyAdmin
      image: phpmyadmin/phpmyadmin:5.1.3
      restart: always
      depends_on:
        - database1
        - database2
      environment:
        PMA_HOST: database1, database2
        PMA_PORT: 3306, 3307
        PMA_USER: databaseuser1, databaseuser2
        PMA_PASSWORD: databaseuser1, databaseuser2
      ports:
        - "8080:80"
      networks: 
        - my_network
volumes:
  database-volume:
  second-database-volume:

networks:
  my_network:
    driver: bridge

我想知道是否有任何构建方式来存档它。

只需将环境变量PMA_HOST 更改为PMA_HOSTS。

phpMyAdmin select server
