Docker comes to Raspberry PI

If you’re not already familiar with Docker, it’s a method of packaging software to include not only your code, but also other components such as a full file system, system tools, services, and libraries. You can then run the software on multiple machines without a lot of setup. Docker calls these packages containers. Think of it like a shipping container and you’ve got some idea of how it works. Shipping containers are a standard size so that they can be moved around at ports, and shipped via sea or land. They can also contain almost anything. Docker containers can hold your software’s code and its dependencies, so that it can easily run on many different machines. Developers often use them to create a web application server that runs on their own machine for development, and is then pushed to the cloud for the public to use.”
