Better way to build a PHP5/Apache server.
Once you've built this Dockerfile as docker build -t octohost/php5-apache . - your next Dockerfile should look like this:
FROM octohost/php5-apache
ADD . /var/www
EXPOSE 80
CMD ["/bin/bash", "/start.sh"]
Simple and quick way to push PHP code up. Thanks to jbfink/docker-wordpress for the Apache start.sh script.
