在运行 Docker Desktop 的 Ubuntu 主机上，我通过 创建了一个新卷docker volume create pgadmin4。但是，我没有在主机上找到该卷。此外，预期的目录/var/lib/docker/不存在；请参阅下面的屏幕截图了解更多信息。
我尝试/var/lib/docker/以 root 用户身份列出目录，但结果仍然不存在，所以这似乎不是权限问题。
我也检查了ps -elf | grep -i "docker"，似乎正在运行的二进制文件在/opt/docker-desktop/目录中；它可能与服务器略有不同docker。
我将非常感谢任何提示或建议，如果您需要更多详细信息，请告诉我。

答案1
Docker Desktop 与 Docker Engine 不同，并且它运行在KVM虚拟机中，而不是直接在主机上运行。
因此，我遵循了官方在线文档检查卷并通过图形用户界面找到该卷的内容。
数据选项卡显示卷中的文件和文件夹以及文件大小。要保存文件或文件夹，请将鼠标悬停在文件或文件夹上，然后单击更多选项菜单。选择另存为，然后指定下载文件的位置。
