Docker is a system for the creation and deployment of applications within containers; it was covered here in October. The 0.7 release is now available, with a long list of new features, including the ability to run on standard Linux kernels, a fancy storage driver subsystem, better control over networking and communications between containers, and more. "It took us a while to find our bearings and adapt to the new, crazy pace of Docker’s development. But we are finally figuring it out. Starting with 0.7, we are placing Quality in all its forms – user interface, test coverage, robustness, ease of deployment, documentation, consistency of APIs – at the center our development process."
