Docker: Sharing a volume on Windows with Docker Toolbox

Question

I'm trying to setup a developer environment through a Docker container on my Windows 7 computer.

I've installed Docker toolbox for Windows.

I have an image with Apache and PHP 5.6 within, and here it is:

FROM php:5.6.15-apache

RUN apt-get update && apt-get install -y \
apt-utils vim git php5-mysql php5-memcache php5-memcached php5-intl \
wget
RUN apt-get install libapache2-mod-php5 -y -o Dpkg::Options::="--force-confdef"
RUN docker-php-ext-install mbstring
RUN docker-php-ext-install pdo pdo_mysql
RUN apt-get install libcurl4-gnutls-dev -y
RUN docker-php-ext-install curl
RUN a2enmod rewrite

ENV APACHE_RUN_USER myname
ENV APACHE_RUN_GROUP www-data
ENV APACHE_LOG_DIR /var/log/apache2
ENV APACHE_LOCK_DIR /var/lock/apache2
ENV APACHE_PID_FILE /var/run/apache2.pid

EXPOSE 80

COPY php.ini /usr/local/etc/php/php.ini
COPY apache-config.conf /etc/apache2/sites-enabled/000-default.conf
RUN echo "ServerName 127.0.1.1" >> /etc/apache2/apache2.conf

This image is created, and I can see it when I run "docker images" in the Docker quickstart terminal.

In my apache-config.conf, I just have a tiny virtual host to access a test website with just an index.php file.

Then I try to create the container in the Docker quickstart terminal:

docker run --name=php5.6_container --rm -v "//c/sites:/var/www/html" -p 80:80 -p 8080:8080 php5.6

I get the following error:

AH00112: Warning: DocumentRoot [/var/www/html/test] does not exist
AH00112: Warning: DocumentRoot [/var/www/html/test] does not exist
[Tue Dec 08 16:36:37.703143 2015] [mpm_prefork:notice] [pid 1] AH00163: Apache/2.4.10 (Debian) configured -- resuming normal operations
[Tue Dec 08 16:36:37.703733 2015] [core:notice] [pid 1] AH00094: Command line: '
apache2 -D FOREGROUND'

It seems like my volume option is not taken into account. And the container is not created.

What could I be doing wrong?

Answer 1

See the note for Windows and Mac at https://docs.docker.com/engine/userguide/dockervolumes/#mount-a-host-directory-as-a-data-volume. Particularly:

If you are using Docker Machine on Mac or Windows, your Docker daemon has only limited access to your OS X or Windows filesystem. Docker Machine tries to auto-share your /Users (OS X) or C:\Users (Windows) directory.

Basically, you will need to move your site files to somewhere such as c:\Users\sites and then mount using something like suggested in documentation:

docker run --name=php5.6_container --rm -v "/c/Users/sites:/var/www/html" -p 80:80 -p 8080:8080 php5.6

Answer 2

• Open "Oracle VM VirtualBox"
• Once "default is selected" click on "configuration"
• Go to "Sheared Folders" Add the desired Folder

• Then restart default by typing in your console

  docker-machine restart default

Answer 3

Step 1: C:/Program Files/Oracle/VirtualBox/VBoxManage sharedfolder add default -name $shared_folder -hostpath d:/data

To show shared folders:

VBoxManage showvminfo default | less

Step 2(a): mount -t vboxsf -o uid=1000,gid=50 $shared_folder /data

Step 2(b): Adding an automount to boot2docker

While logged into the machine, edit/create (as root) /mnt/sda1/var/lib/boot2docker/bootlocal.sh by adding below block to the file, sda1 may be different for you...

mkdir -p /data mount -t vboxsf -o uid=1000,gid=50 $shared_folder /data

Then, docker-machine restart default

Step 3: Adding volume when running the container(gogs as example) docker run --name=gogs -rm --net=host -d -v /fuple:/data gogs/gogs
