1. DOCKER FOR MORE THOROUGH AWESOMENESS
3. WHAT • Docker is a lightweight virtualization platform. • It simplifies deploying applications and services to any platform that supports Docker. • Think of it as a cargo container for your service. • Pack, ship and run your service in a completely isolated environment easily.
4. WHAT • Docker service written in Golang. • Uses LXC and AUFS (a copy-on-write filesystem) for Linux to virtualize process(es). • Virtualization overhead is very low; effectively zero memory/CPU cost above native service. • Completely isolated environment.
5. HOW 1. Create a Dockerfile in your source code root
9. HOW 1. After installing docker and its base image, 2. git clone https://github.com/mrallen1/dice-service 3. docker build -t dice-service .! 4. docker run -t dice-service! 5. curl -X POST -d'roll=3d6' localhost:<assigned-port>
10. WHY • Think of it as git for filesystems (push and pull primitives) • Makes deploying services to {your own | cloud | PaaS } servers easy and repeatable • Completely isolates your application environment • Faithfully replicates your environment for dev and testing • It's fun!
11. WHERE • http://docker.io • https://index.docker.io 
 (The CPAN of docker images) • https://github.com/dotcloud/docker • https://github.com/mrallen1/dice-service
