The devel tree of CentOS Atomic Host, which features a trimmed-down system image that leaves out kubernetes and related system components, is a great place to experiment with alternative methods of running these components, and swapping between them. http://www.projectatomic.io/blog/2016/09/running-kubernetes-in-containers-on-atomic/

This week, the Fedora Project released updated images for its Fedora 24-based Atomic Host. Fedora Atomic Host is a leading edge operating system designed around Kubernetes and Docker containers. Fedora Atomic Host images are updated roughly every two weeks, rather than on the main six-month Fedora cadence. Because development is moving quickly, only the latest […]

A single Atomic Host is a fine place to run your containers, but these hosts are much more fun when bunched into clusters, a task that we can manage with the help of Kubernetes. There are a lot of great guides for setting up a kubernetes cluster, but my favorite involves ansible and vagrant, and […]

Fedora 22’s Atomic Host dropped most of packages for the web-based server UI, cockpit, from its system tree in favor of a containerized deployment approach. Matt Micene blogged about running cockpit-in-a-container with systemd, but people have expressed interest in learning how to start this container automatically, with cloud-init. via Running a Containerized Cockpit UI from […]

Kubernetes, the open source orchestration system for Docker containers, is a fast-moving project that can be somewhat complicated to install and configure, especially if you’re just getting started with it. Fortunately, the project maintains some really well-done getting started guides, the simplest of which steps you through running Kubernetes, in Docker containers, on a single […]

Recently, I blogged about docker-on-loopback-storage woes and workarounds – a topic that came up during several conversations I had at last month’s Dockercon. Another frequently-discussed item from the conference involved Docker on CentOS 6, and whether and for how long users can count on running this combination. via Docker, CentOS 6, and You — Project […]

I’ve heard negative things about the Fedora|CentOS Docker storage configuration in the past, and while manning the Red Hat booth in San Francisco at DockerCon last week, I spoke to a number of people who’ve experienced these storage issues themselves. Much of the trouble, I think, boils down to how Docker in Fedora and CentOS […]

Just over a week ago, I headed to the outskirts of San Francisco’s Financial District to attend Container Camp, a one-day, single-track conference focused primarily on the Docker ecosystem. The Container Camp lineup included a nice mix of project talks and real user stories that left me looking forward to attending the next time the […]
