macos - docker 镜像在 macos 上物理存储在哪里？

Question

下面显示几个位置。 https://forums.docker.com/t/where-are-images-stored-on-mac-os-x/17165/4

但我看不到哪个文件对应于哪个图像。谁能告诉我如何找出每张图片的物理位置？谢谢。

$ docker ps  -a

Docker 不能在 Mac 上运行，因为 macOS 内核不兼容（即 BSD 与 Linux）。Docker 实际上是在使用 HyperKit 的虚拟机中运行的。

而Docker.raw你上面列出的就是这个虚拟机的虚拟磁盘。

所有 docker 镜像都存储在虚拟机内部（在 Docker.raw 文件中），因此您无法在 Mac 文件系统上看到它们。
