  • Deploy containers with Atomic Host, Ansible, and Cockpit

    In the course of my job at Red Hat, I work with Docker containers on Fedora Atomic host every day. The Atomic Host from Project Atomic is a lightweight container OS that can run Linux containers in Docker format. It’s been modified for efficiency, making it optimal to use as a Docker run-time system for cloud environments.

    Fortunately I’ve found a great way to manage containers running on the host: Cockpit. Cockpit is a remote manager for GNU/Linux servers with a nice Web UI. It lets me manage servers and containers running on the host. You can read more about Cockpit in this overview article previously published here. However, I also wanted to automate running containers on the host, which I’ve done using Ansible.

    Note that we cannot use the dnf command on the Atomic Host. The host is designed not as a general purpose OS, but to be more fit for containers and other purposes. But it’s still very easy to set up applications and services on the Atomic Host. This post shows you how to automate and simplify this process.

  • Docker: Making the Internet Programmable
    Docker, and containers in general, are hot technologies that have been getting quite a bit of attention over the past few years. Even Solomon Hykes, Founder, CTO, and Chief Product Officer at Docker started his keynote with the assumption that people attending LinuxCon Europe know that Docker does containers, so instead of focusing on what Docker does, Hykes used his time to talk about Docker’s purpose saying, “It really boils down to one small sentence. We're trying to make the Internet programmable.” Hykes described this idea of making the Internet programmable with three key points. First, they are focused on building “tools of mass innovation” designed to allow people to create and innovate on a very large scale. Second, applications and cloud services are allowing the idea of the Internet as a programmable platform to be realized, and they want to make this accessible to more people. Third, they are accomplishing all of this by building the Docker stack with open standards, open infrastructure, and a development platform with commercial products on top of the stack.
  • How to benchmark your Linux system
    The Software Center list will also include individual tests. These can be fine to use, but they can be tedious to open and configure manually. Keep your eye out for an entry called Phoronix Test Suite, or PTS for short. The Phoronix Test Suite is a powerful program that can run a single test, or an entire battery. PTS offers some built-in suites (collection of tests), or you can design your own suite. When tests are completed, you can choose to upload the test results to, where other users can see your results and even run the exact same tests on their PC.
  • Wunderlist Electron App for Linux
    Missing Wunderlist on Linux? You don’t need to thanks to Wunderlistux, an Electron-based desktop app. It doesn’t claim to be anything more than a wrapper around the official Wunderlist web app (which, yes, you could just open in a new browser tab).
