WSL2 的 %USERPROFILE%\AppData\Local\Docker\wsl\distro\ext4.vhdx 文件中存储了什么？

Question

I am using Docker with WSL2 integration on Windows 10 Home.

While following this question to change the location of the docker images I came across this file:

%USERPROFILE%\AppData\Local\Docker\wsl\distro\ext4.vhdx

and couldn't find any explanation online regarding the function of this file.

Answer 1

When you run Docker Desktop WSL2 it'll create 2 vm's, one contains volumes, images, etc., and the other is related to the actual Docker Desktop itself, which is the one you're asking about. It's much smaller.

You can see both of them with: wsl -l -v

The one you're asking about is for the docker-desktop vm.
