我是新的docker和容器世界。有麻烦设置mysql客户端在我的本地机器上。我指的是this教程。
我的docker-compose.yml文件看起来像

version: "3.7"
services: 
  db:
    image: mysql
    container_name: "mySql-wordpress"
    restart: always   
    environment: 
      MYSQL_ROOT_PASSWORD: p@55w0rD@1234
    ports: 
      - "3306:3306"
    command: --default-authentication-plugin=mysql_native_password
    networks: 
      - back
  adminer:
    image: adminer
    restart: always
    ports:
      - 8282:8080
networks: 
  back:
volumes: 
  db_data:

没有问题，我能够成功执行docker-compose up -d命令。以下是docker ps命令的输出

CONTAINER ID        IMAGE                   COMMAND                  CREATED             STATUS              PORTS

                                    wordpressdemo_phpmyadmin_1

现在，当我尝试登录到Adminer portal时，我收到错误消息
SQLSTATE[HY000] [2002] No such file or directory

我也尝试安装phpmyadmin/phpmyadmin图像，但得到以下错误：
mysqli_real_connect(): The server requested authentication method unknown to the client [caching_sha2_password]
mysqli_real_connect(): (HY000/2054): The server requested authentication method unknown to the client

我的SQL Server似乎没有正确设置。有任何指针吗？

通过图片mysql:5.7，我可以在phpMyAdmin上看到以下两条错误消息
mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known
mysqli_real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known个
