Docker wsl2 linux like path for mapped folders are missing

Docker Desktop for Windows
1

this is repost of my SO post that no one could answer yet, since I’m new user I couldn’t paste pictures, see the full thread in SO

I’m searching for more than two days and unfortunately, none of the solutions worked so far.

I am running my docker under WSL 2 and I want to know where the mapped folder is.

let say

$host> docker run -ti -v /home:/home2 continuumio/anaconda3 bin/bash

$root@9fce1cb15cae> cd /home2
$root@9fce1cb15cae: /home2# ls
$root@9fce1cb15cae: /home2# touch test.txt
$root@9fce1cb15cae: /home2# ls
test.txt

now if I come out of the container, and search for test.txt I can’t find it anywhere

if I look into the wsl folder I have these two distro

and if I run the wsl -l I get this

└ $ wsl -l
Windows Subsystem for Linux Distributions:
docker-desktop (Default)
docker-desktop-data

so I’m assuming the mapping should be available inside the docker-desktop as it’s the default

if I run wsl ls /home I get empty result

the docker-desktop-data doesn’t have a home folder to begin with

if inside my windows I query for /home there isn’t such folder

if I look for the docker volume, there isn’t any volume available

and if I inspect the mounted volume, there isn’t any.

so in summary

  • there is no local folder in my windows named home
  • the docker-desktop home folder is empty
  • the docker-desktop-data doesn’t have any home folder
  • in drive C: I don’t have any home folder

so my big question is where is the mapped folder?

interestingly if I write a windows path as the mapping, the mapping works quite well

$host> docker run -ti -v c:\users\me\repo\testing-docker:/home2 continuumio/anaconda3 bin/bash

$root@9fce1cb15cae> cd /home2
$root@9fce1cb15cae: /home2# ls
$root@9fce1cb15cae: /home2# touch test.txt
$root@9fce1cb15cae: /home2# ls
test.txt

if I go to the testing-docker I can see test.txt

so magically if I write a windows path, it works well, but as long as it’s a linux path it map it to somewhere that I don’t know and I can’t find it. it doesn’t throw any errors. if I remap the /home to another container, I can see the test.txt is there. so I’m sure the file is somewhere, but I don’t know where. so the question is where it is get mapped, where it could be that isn’t inside the wsl? I tried all the folder that mentioned in other SO answers, but none of them worked for me

I’m using Docker version 20.10.20, build 9fdeb9c
