Installing Docker on Ubuntu This post is essentially my notes on getting started quickily with Docker. I set this up in my lab machines running Ubuntu 16.04.1 LTS, the steps are based on the excellent instructions written on the Docker getting started guide Add the Docker project repository to APT sources sudo apt-get install apt-transport-https ca-certificates sudo apt-key adv \ --keyserver hkp://ha.pool.sks-keyservers.net:80 \ --recv-keys 58118E89F3A912897C070ADBF76221572C52609D echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" | sudo tee /etc/apt/sources.

When developing a package(any piece of reusable code, like a class library to be loaded or a web service that’s accessible through HTTP) that has a published API it is necessary to have a clear separation between the API version and the codebase version of the package. The API is what is exposed from the package for the users to consume, this should be documented clearly and the module should have thorough tests included that tests the entire published API to assert it conforms to the documented.
