volume mount pb when using docker for win

[looztra]

• Docker for windows : 17.12.0-ce-win45 (15017)

$ docker run --rm -v //d/tmp/Formation--Modele-cfk/Gruntfile.js:/data/Gruntfile.js -v //d/tmp/Formation--Modele-cfk/Slides/:/data/Slides/ -v //d/tmp/Formation--Modele-cfk/package.json:/data/package.json -v //d/tmp/Formation--Modele-cfk/CahierExercices:/data/CahierExercices -v //d/tmp/Formation--Modele-cfk/PDF:/data/PDF zenika/formation-framework:v3 grunt pdf
Loading "Gruntfile.js" tasks...ERROR
>> Error: Cannot find module '/data/Gruntfile.js'
Warning: Task "pdf" not found. Use --force to continue.

Aborted due to warnings.

When I go inside the container thx to a bash shell:

$ winpty docker run -ti --rm -v //d/tmp/Formation--Modele-cfk/Gruntfile.js:/data/Gruntfile.js -v //d/tmp/Formation--Modele-cfk/Slides/:/data/Slides/ -v //d/tmp/Formation--Modele-cfk/package.json:/data/package.json -v //d/tmp/Formation--Modele-cfk/CahierExercices:/data/CahierExercices -v //d/tmp/Formation--Modele-cfk/PDF:/data/PDF zenika/formation-framework:v3 bash

looks like mounting files as volumes under docker for windows does not work (anymore?) because /data/Gruntfile.js is a directory and not a file like expected

Your volume option might not be correct because of path transformations applied by msys (which is part of git bash). Could you try removing the leading slash from the host path and prepending the whole command by MSYS_NO_PATHCONV=1?

If that still gives a folder then it must be some kind of docker for windows bug, right?

[looztra]

works fine like this:

christopher@looz8 MINGW64 ~/workspace/Formation--Modele-cfk (docker_win10_exp)
$ MSYS_NO_PATHCONV=1 docker run --rm -v /c/Users/christopher/workspace/Formation--Modele-cfk/Gruntfile.js:/data/Gruntfile.js -v /c/Users/christopher/workspace/Formation--Modele-cfk/Slides/:/data/Slides/ -v /c/Users/christopher/workspace/Formation--Modele-cfk/package.json:/data/package.json -v /c/Users/christopher/workspace/Formation--Modele-cfk/CahierExercices:/data/CahierExercices -v /c/Users/christopher/workspace/Formation--Modele-cfk/PDF:/data/PDF zenika/formation-framework:v3 grunt pdf
