Can't mount a volume on Windows 7

[denisvmedia]

I'm getting this error when I run docker-composer up:

ERROR: for php  Cannot create container for service php: Invalid bind mount spec "D:\\Work\\docker\\project\\sites\\admin:/project_admin:rw": Invalid volume specification: 'D:\Work\docker\project\sites\admin:/project_admin:rw' ←[31mERROR←[0m: Encountered errors while bringing up the project.

Here is what I have in my docker-compose.yml:

        volumes:
            - ../sites/project:/project_admin

This works like charm in native Docker for Windows 10, but with Docker Toolbox on Windows 7 there is a problem. Is it a bug? Or what am I doing wrong?

I have the same problem with Docker Toolbox on Windows 10.

ERROR: for volumes_source  Cannot create container for service volumes_source: Invalid bind mount spec "C:\\Users\\Lars\\Documents\\Projecten\\smaakgemak:/var/www/laravel:rw": Invalid volume specification: 'C:\Users\Lars\Documents\Projecten\smaakgemak:/var/www/laravel:rw'
�[31mERROR�[0m: Encountered errors while bringing up the project.

docker-compose.yml (part that fails):

 volumes_source:
        image: tianon/true
        volumes:
            - ./:/var/www/laravel

EDIT: Downgrading to Docker Toolbox 1.2.0 is a workaround.

I have the same problem on Windows 7 too with the 1.12.5 release.

ERROR: for mysql  Cannot create container for service mysql: 
Invalid bind mount spec "C:\\www\\docker\\mysql:/var/lib/mysql:rw":
Invalid volume specification: 'C:\www\docker\mysql:/var/lib/mysql:rw'
ERROR: Encountered errors while bringing up the project.

Here the line fails in my docker-compose.yml:

 volumes:
        - ./mysql:/var/lib/mysql

I tried 1.12.4 release, it's the same problem.
I downgraded to 1.12.3 to resolve it.

Same problem on Windows 10 with Docker Toolbox 1.12.5.

Fixed by downgrading to Docker Toolbox 1.12.3 (did not attempt 1.12.4).

👍
Win 7
Toolbox 1.12.5

Have any one tried v1.13.0-rc4?

EDIT
v1.13.0-rc4 hasn't fixed it either. Had to downgrade to 1.12.3 (1.12.4 also fails).

This bug from docker-compose 1.9.0 (Include in Docker Toolbox 1.12.4+)

Docker Toolbox 1.12.3 include docker-compose 1.8.1. It work!.

[aimakun]

It's from breaking changes in Docker Compose 1.9.0 that need to set additional env variable for Docker Toolbox. https://github.com/docker/compose/releases/tag/1.9.0

[leocavalcante]

Thanks @aimakun! Setting COMPOSE_CONVERT_WINDOWS_PATHS=1 works.

[t0ngt0n9]

@aimakun thank you! It works now! =)

[jaroslavzivny]

@leocavalcante Where have you gotten the 1.12.3 version? I cannot find it. Thanks!

[leocavalcante]

@jaroslavzivny Setting COMPOSE_CONVERT_WINDOWS_PATHS=1 solves this issue, but if you want to downgrade anyway, you can download old builds navigating through this repo releases: https://github.com/docker/toolbox/releases/tag/v1.12.3

I downgraded to 1.12.3 and 1.8.1 for docker-compose, but i still run into issues : i now have "Invalid bind mount spec "local_path:/var/www/html': invalid mode: /var/www/html. I am on Windows 7, and my volume is set like that:

volumes: - /C:/users/jct/code/03-docker/:/var/www/html

I tried several things, for the path : with '/', with '//', with only '.:/var/www/html', and more...
I tried with or without COMPOSE_CONVERT_WINDOWS_PATHS=1 or 0.

Any other ideas that could help ?

[leocavalcante]

@dargoan You need to "translate" your Win path to a Unix-like:
/c/users/jct/code/03-docker

What is happening is that you are using two ":" then Docker guesses as:
First part /C is the host
Second part /user/jtc... is the container
And the optional thirdy part was given as /var/ww/html

But this third part should be the mode, so Docker errors with: invalid mode: /var/www/html

If you are using Git Bash or Docker Quickstart Terminal, then /$PWD should work fine. If you are using Composer then relative path should work just fine as well:

volumes:
  - ./:/var/www/html

[johanchouquet]

Thanks for the quick answer @leocavalcante (amazing!) ! This is true, i read that but forgot. I tried, but now, it tells me 'Cannot create container for service app: The working directory 'C:/Program Files/Git/var/www/html' is invalid. It needs to be an absolute path.

I already had this error message, but I don't see why Docker talks about my Git directory...

[leocavalcante]

You need to put a slash before $PWD, I often run into this issue too 😆

docker run -v /$PWD:/var/www/html -p 8000:80 php:apache

[johanchouquet]

Thanks again! Well, for now docker run is OK. I managed to do so. But the problem remains when trying to do : docker-compose run --rm -d -w /var/www/html app composer install with the definitions of volumes such as :
//C/users/jct/code/03-docker/:/var/www/html

Now, I'm getting this error message : Cannot create container for service app: The working directory 'C:/Program Files/Git/var/www/html' is invalid. It needs to be an absolute path.
