非常令人沮丧的错误。我希望你能给我一些建议。
我删除了所有映像，所有容器，并使用docker对系统进行了修剪。
然后，我运行以下命令。我知道我没有指定mysql主机和密码，但是谁在乎，这仍然可以正常工作或向我显示phpmyadmin的主页，我可以在其中登录，并且应该说mysql无法连接。
sudo docker run --name adminphp1 -d -p 8000:80 phpmyadmin/phpmyadmin。
运行此命令后，看到容器列表，向我显示以下内容：
389268e87d4b phpmyadmin/phpmyadmin "/run.sh supervisord…" 2 minutes ago Up 2 minutes 9000/tcp, 0.0.0.0:8000->80/tcp adminphp1
9000 / tcp来自哪里？
运行docker logs adminphp1后，它显示以下内容：
Complete! phpMyAdmin has been successfully copied to /var/www/html

然后我尝试使用website.com:8000进行访问，浏览器显示我经过了一段时间后无法访问该网站。
只要您能提出建议，我们将不胜感激。
