17. “A SERVER SHOULD BE LIKE A PHOENIX, REGULARLY RISING FROM THE ASHES.” Martin Fowler
20. Isolation Portability Compatibility Automation Speed “Ship anything... anywhere”
21. • LXC Containers • “Chroot on steroids” • AUFS • layered view on merged directories • copy-on-write What and how?
23. git clone https://github.com/ndemoor/phpbnl-demo
24. # Dockerfile: memcached FROM ubuntu # make sure the package repository is up to date RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list RUN apt-get update # install memcached RUN apt-get install -y memcached # run as user daemon (memcached doesn't allow to run as root) USER daemon # expose memcached port EXPOSE 11211 # Launch memcached when launching the container # CMD [ "memcached" ] ENTRYPOINT ["memcached"]
25. # Dockerfile: nginx and php FROM ubuntu # make sure the package repository is up to date RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list RUN apt-get update # install php and nginx RUN apt-get install php5-common php5-cli php5-fpm php5-memcache php5-mcrypt nginx RUN echo "cgi.fix_pathinfo = 0;" >> /etc/php5/fpm/php.ini RUN echo "daemon off;" >> /etc/nginx/nginx.conf EXPOSE 80
26. 0.1 App
27. # Pseudo-Dockerfile: app FROM mynamespace/nginx-php MAINTAINER myself ADD . /var/www RUN cd /var/www && install WORKDIR /var/www EXPOSE 80 CMD [ "./start.sh" ]
