Docker toolbox and windows paths

(Nabil Redmann) #1

So I need help to get this clarified:

Docker toolbox (docker.exe) has issues to with windows paths in the --volume param.


  • colon “:” do not work -> no other drive then C possible
  • spaces “” do not work -> no default windows folders are possible (Program Files, …)
  • backslashes “\” do not work -> no shell/env-variables for paths are possible
  • no relative path gets resolved “./..” -> absolute path wanted

-> Kitematic dies the same death on those Paths.


D:\Github Projects\Testproject 1\>docker.exe -p 8000:80 -v "%cd%\www":/app --name "Test Project1" bananaacid/docker-php7.2-kitematic

resulting in, but not accepted:

docker.exe -p 8000:80 -v "D:\Github Projects\Testproject 1\www":/app --name "Test Project1" bananaacid/docker-php7.2-kitematic

Same issue on cmd.exe as well as powershell.exe.

So --volume is actually not usable on windows? Or is there any workaround vor all these problems?

edit (partial solution: for drive and backslashes, not spaces):
since docker is using cygwin internally, all paths have to be converted to cygwin paths (cygpath). $(pwd) is powershell inserting the current path, executing $(& ...cygpath "..currentpath..") for docker to get a unix path:
tried powershell>docker run -p 8000:80 -p 8443:443 --volume "$(& "C:\Program Files\Git\usr\bin\cygpath.exe" "$(pwd)\www")":/app --name TestProject1 bananaacid/docker-php7.2-kitematic

which does in fact substitute correctly, but the space is still not accepted. A path without a space would work. Result so far: /d/Github Projects/Testproject 1/www/
Manually escaping the space with a backspace, does not work either:
--volume "/d/Github Projects/Testproject 1/www/":/app
--volume "/d/Github\ Projects/Testproject\ 1/www/":/app
--volume /d/Github\ Projects/Testproject\ 1/www/:/app
--volume "/d/Github Projects/Testproject 1/www/:/app"

docker-compose does do resolve

  - ./..:/app


docker inspect shows the mounts with correct path, but VOLUMES is still not being set.

-> no solution yet.

Hi! check this out!
see if this works and let me know.
this just worked for me!
here is the link for my reply on another post here.

Since I also have it on drive D, this does not work. As I said: spaces.

compose up does not work as well.

Kitematic’s select folder dialog does not work with this as well.

Somewhat of a solution: install the windows wsl feature, run the wsl’s bash.exe (not cygwin’s) -> then docker.exe .... --volume "/d/Github Projects/Testproject 1/www/" ... will work (as on OSX)
