The Anatomy of a Docker Image
Over the past few years, container technologies (like Docker) have become essential to many a developer's workflow -- be it for local development, testing, CI or production rollouts. In this talk, I will shed light on one of the underlying principles of Docker: the OCI image and distribution specifications. These describe the file format of a Docker image and the API of a Docker registry. Understanding these will help you understand what's actually going on when you run commands like "docker build" or "docker pull". I will also present a case study of a project in which we used these specifications to build a container image solution that implemented features that would have been impossible to implement using the regular tools.
