Cannot provide paths to docker run in windows

[atrauzzi]

When I try to run this: winpty docker run --volume="./laravel:/app" composer/composer "$@", I get the following error:

invalid value "`.\\laravel:\\app`" for flag --volume: \app` is not an absolute path
See 'docker run --help'.

Running: Docker version 1.9.1, build a34a1d5

Hm, sounds like the windows shell converting slashes to backslashes, I think there are some other issues about that, and iirc, there was as workaround to prevent it being "smart".

I do see, however, that you're trying to use a relative path (.\\laravel) for the host path, that's not supported, and should be an absolute path (e.g. C:\Users.....)

[thaJeztah]

I think this discussion describes it; #13741, and this link http://www.mingw.org/wiki/Posix_path_conversion

[atrauzzi]

Requiring an absolute path is not practical though. This is in the context of a shared project. Not everyone will put it in the same location on their machines.

Also, I'm using docker toolbox, not cmd or power shell.

Requiring an absolute path is not practical though. This is in the context of a shared project. Not everyone will put it in the same location on their machines.

You could consider using docker-compose; docker-compose allows you to define bind-mounted volumes relative to the location of the docker-compose.yml file. Using a docker-compose file allows you to specify all options needed to run your containers in a single file, which makes it ideal for sharing between team members (ie, just run docker-compose up -d will start all containers for the project with the right options).

On Linux, using --volume $(pwd)/laravel:/app/ is usually the way to convert the current directory to an absolute path (but not sure if there's an alternative to that on Windows 😊)

Also, I'm using docker toolbox, not cmd or power shell.

IIRC, toolbox basically starts a cmd or powershell session, with the environment set up to connect to your virtual machine but I don't have access to a Windows box currently, so I'm not able to test a.t.m.

/cc @JeffDM for Docker Toolbox, because this is more an issue with docker-toolbox than docked

[atrauzzi]

I'm already using compose to simulate an environment. This is just a one off command.

Thanks @thaJeztah.

@atrauzzi I'll investigate the path conversion in docker/toolbox on Windows

[jmorganca]

See docker-archive/toolbox#282

Thanks!

[thaJeztah]

Thanks @JeffDM

@atrauzzi let's continue the discussion in docker-archive/toolbox#282. I'll close the issue here

This hack seems to work like a charm if you have downgraded to 1.9 from the AUFS issues in 1.9.1

docker create -v //c/Users/myuser:/myuser --name data hello-world
winpty docker run -it --rm --volumes-from data ubuntu
