Error in absolute path when using Docker 1.6 on Windows 7

[joao-parana]

I'm trying to execute de command

docker run -v "$(pwd)":/app -v /var/run/docker.sock:/var/run/docker.sock -ti dduportal/docker-compose:latest --help 

but I'm getting the Error:

invalid value "c:\\Users\\user\\docker\\myFirstService;C:\\Program Files (x86)\\Git\\app" for flag -v: \Users\user\docker\myFirstService;C:\Program Files (x86)\Git\app is not an absolute path
See 'c:\Program Files\Boot2Docker for Windows\docker.exe run --help'.

I´m runnig inside the MINGW32 shell open by Boot2Docker start.lnk instaled in my Desktop

What is going wrong ?

Hi @joao-parana !

It seems related to Windows/MinGW32 path conversion at the call. Maybe an updated documentation will be needed seems docker is know officially supported on Windows.

Just to help me (and others future concerned users), could you show me what you have for those commands, in the same context (same folder, same docker, same host, etc. ) :

• pwd
• echo "$(pwd)"

?

Hi @dduportal,

I have the same problem on Windows 8.1, so I will answer your question with my values:

• /c/ (when I am in my C:\ folder)
• /c/newFolder/ (when I am in C:\newFolder)

Same values for echo "$(pwd)" :-(

This is related to issue moby/moby#12590. In Windows, the host path has to be prepended with an extra slash, otherwise msysgit will convert the path to a wrong value. So the actual docker command has to look like this:

docker run -v /$(pwd):/app ...

I guess this has to be modified in the way Docker Compose generates the volume path.

Hi all !

Thanks for you feedback.

As of @joostfarla comment, i've updated the documentation to help that.

Don't hesitate to re-open the issue if it does not work for you.
