This creates a docker image based on ubuntu:16.04 that runs apache and php7.1.
The following command will create the image and tag it apache. Of course, you can tag it whatever you want just remember the tag for the next command.
docker build -t apache .
The build file accepts a documentroot argument to set the APACHE_DOCUMENTROOT environment variable. By default the document root is set to /var/www/app but if you wish to build with a different document root, you can set the build argument to which ever directory you want like so:
docker build -t apache --build-arg documentroot=/var/www/app/public .
This projects contains an apache.conf file. This file will get moved to /etc/apache2/sites-available/000-default.conf and will become the default apache configuration. Feel free to edit this file in anyway to add the settings you may need apache to have. Right now its configured for applications that require followsymlinks such as laravel, wordpress or drupal.
In this file I am utilizing the apache environment variable APACHE_DOCUMENTROOT to have the virtualhost automatically follow the document root to which ever directory we set it to be in the build command. See "Building the image" above.
This image is configured by default to run apache with the document root set to /var/www/app. When mounting a volume, mount your directory to this directory. example:
## using mount
docker run --name apache --mount type=bind,source="$(pwd -P)",target=/var/www/app apache
## using v
docker run --name apache -v $(pwd -P):/var/www/app apache
This command runs a container with your current working directory mounted to /var/www/app. It also names the container apache. I find using names useful for when I need to remove the container or stop it. Totally up to you if you want to use it.
