    Develop a Docker Authorization Plugin in Python

    30 Jul 2016
    Docker Engine has a great plugin framework that allows you to write code that integrates cleanly with the Docker daemon. There are 3 different kinds of plugins you can create: authorization (authz), network, or volume. This post shows you how to develop a Docker authorization plugin in Python. An authorization plugin can control access to access to the Docker daemon based on both the current authentication context and the command context in order to approve or deny requests.

    Top 3 Sessions at DockerCon 2016

Naturally, the best place to start is Getting started on Carina. 😀

    State of the OpenStack API Working Group: Liberty Edition

    14 May 2015
    The API is the foundation of all user interaction with OpenStack. It’s fundamental to the usability of OpenStack as a platform. A well designed and consistent API across all OpenStack projects is necessary, otherwise all of the layers above the API (SDKs, CLIs, Web Apps, Mobile Apps) suffer. As such, the OpenStack API Working Group (WG) has a clear mission.
