Blogging On Docker: Piecrust To The Rescue

I love blogging. I hate blogging systems. I hate content management systems. I just want to blog. That’s what PieCrust is all about - it lets you blog.

It is powerful static website generator perfect for my needs (and for yours as well?). Blogging with PieCrust is really a piece of cake:

  1. prepare post
  2. serve site
  3. bake site
  4. send it off to the public

I love having clean OS. That’s what Docker is all about - for me. Running PieCrust on Docker is really easy, it does not clutter your PC and it just works.

If you ever want to use PieCrust on Docker, why don’t you start with this code? FROM centos:centos6

RUN rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
RUN rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
RUN rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

RUN yum --enablerepo=remi,remi-php55 install -y php php-mbstring php-opcache php-cli php-pear php-common && yum clean all
RUN php -r "readfile('https://getcomposer.org/installer');" | php
RUN echo "date.timezone = Europe/Prague" >> /etc/php.ini
RUN mv composer.phar /usr/bin/composer
RUN php -r "eval('?>'.file_get_contents('http://backend.bolt80.com/piecrust/install'));"
RUN mv piecrust.phar /usr/bin/chef

CMD ["/bin/bash"]

Running sudo docker build --tag=piecrust . will result in having docker container ready to run. Just run sudo docker run -it -p 8080:8080 -v /host_piecrust_path/:/container_path piecrust /bin/bash in terminal. While in container terminal, run chef serve -n -p 8080 -a and visit http://localhost:8080. You should see your PieCrust site up and running.

The last command tells chef to serve your site on port 8080 (which should be free unless you’re running Tomcat or something like that) and make it listen on every available network interface. If you used instead, you would never reach your site from outside the container.

See? Easy.
