Absolute paths change with git bash on windows

[kriku]

docker run -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1; done"

using from git bash on win10 cause

C:\Program Files\Docker\Docker\Resources\bin\docker.exe: 
Error response from daemon: 
oci runtime error: 
exec: "C:/Program Files/Git/usr/bin/sh": 
stat C:/Program Files/Git/usr/bin/sh: no such file or directory.

and docker ps -a returns

CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS               NAMES
82be3202167b        ubuntu              "C:/Program Files/Git"   About a minute ago   Created                                 jovial_engelbart

seems like git bash change all dirs from root to local one, related to git bash installation

exec this command from power shell works well

[kriku]

also it change dir when adding a data volume

docker run -d -P --name web -v /webapp training/webapp python app.py

"Mounts": [
    {
        "Name": "945c5b0f0e3b140dad75b0de9850f504c37ef8472c94bd69550bc89af4210914",
        "Source": "/var/lib/docker/volumes/945c5b0f0e3b140dad75b0de9850f504c37ef8472c94bd69550bc89af4210914/_data",
        "Destination": "C:/Program Files/Git/webapp",
        "Driver": "local",
        "Mode": "",
        "RW": true,
        "Propagation": ""
    }
],

running this command in power shell works fine

find similar issue on stack overflow

shell is mangling the file name according to these rules

Works fine when using the normal Windows command prompt, just not with Git-Bash

Yes, that's mingw trying to be smart, and converting paths. It's not a bug in Docker, but the way mingw handles these paths. Here is some more information about that "feature"; http://www.mingw.org/wiki/Posix_path_conversion. Prefixing the path with a double slash (//bin/bash) should prevent this, or you can set MSYS_NO_PATHCONV=1, see http://stackoverflow.com/questions/7250130/how-to-stop-mingw-and-msys-from-mangling-path-names-given-at-the-command-line#34386471

(but I'm not on Windows myself, so cannot check).
