macos - docker 镜像在 macos 上物理存储在哪里？

Question

以下显示了几个位置。 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 上原生运行，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。

而你上面列出的Docker.raw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。
