Docker image with fairly minimal requirements for running Symfony 2.
Based on/provides:
- Debian Jessie
- Apache 2.4
- PHP 5.6 (mod_php and cli)
- php5-intl
- php5-curl
I needed an image based on Debian, and I believe the image should include as few additional components as possible (you can base an image off this with your additional requirements).
You can build and run a Symfony 2 demo application from scratch with the following steps.
Create a Symfony project on the host system:
mkdir ~/hello && cd ~/hello
docker run --rm -v $(pwd):/app composer/composer create-project symfony/framework-standard-edition --no-interaction .
Create the Dockerfile:
echo "FROM fazy/apache-symfony" > Dockerfile
echo "ADD . /var/www/main" >> Dockerfile
Build and run the Docker image:
docker build -t symfony/hello .
docker run -d -p 8000:80 --name hello symfony/hello
Visit your new website:
curl -sS http://localhost:8000/app/example
To build a container including an existing Symfony app:
Create a Dockerfile in the root of your application (e.g. /var/www/my-app):
FROM fazy/apache-symfony
ADD . /var/www/main
You might want to replace the above ADD line with something more specific:
ADD vendor /var/www/main/vendor/
ADD app /var/www/main/app/
ADD src /var/www/main/src/
ADD web /var/www/main/web/
Adding vendor first might help a little with caching, assuming vendor changes less frequently than the others.
Build your container and commit:
cd /var/www/my-app
docker build -t myname/myapp .
docker commit
You can then pull and run your Docker image anywhere.
To install more packages, add this to your Dockerfile:
RUN apt-get update \
&& apt-get -yq install \
<package-1> \
<package-2> \
&& rm -rf /var/lib/apt/lists/*
Replace <package-1>, <package-2> with a list of packages to install.
To use your own Apache config, you can create your own version of the vhost.conf in this project, then
ADD it in your Dockerfile:
ADD vhost.conf /etc/apache2/sites-available/000-default.conf
