Download and Get Involved with Fedora Atomic 24
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…

fedora and docker storage
While (pretty much) everyone who’s using docker is running it on Linux, and while lots of people run docker on their laptops and desktops, most aren’t running it directly on Linux desktops and laptops. Instead, most individual docker users are relying on some sort of purpose-built Linux distribution running as a virtual machine on their…

HTTPS Everywhere: Encryption for All WordPress.com Sites
Originally posted on WordPress.com News: Today we are excited to announce free HTTPS for all custom domains hosted on WordPress.com. This brings the security and performance of modern encryption to every blog and website we host. Best of all, the changes are automatic — you won’t need to do a thing. As the EFF points…

blogging, control and open source
I’ve been sort of trying to get blogging again on WordPress lately, and as part of that, I’ve been paying more attention to the blogs I’m following using the WordPress Reader function. Recently, on Om Malik’s blog, I saw this item, pointing to the blog of photographer Eric Kim: I clicked because I’ve been thinking…

testing flannel
I noticed today (maybe I’ve noticed before, but forgotten) that the version of flannel in Fedora 23 is older than what’s available in CentOS. It looks like this is because no one tested the more-recent version of flannel in Fedora’s Bodhi, a pretty awesome application for testing packages. Why not? Maybe because it isn’t always…

You don’t want a custom tree, you want atomic-pkglayer
Atomic system updates are at least half of how “Atomic Hosts” earn their Fallout-flavored appellation. Where a standard Fedora, RHEL or CentOS host gets its updates from a sack of RPMs downloaded from various repositories and exploded out where appropriate, the Atomic editions of these distros consume this same software in pre-exploded-and-composed-into-an-image form. One tricky…

New Atomic Host verb: rpm-ostree deploy
Originally posted on Colin Walters: TL;DR: We’ve improved the host version management in Fedora Atomic Host, and you can now use atomic host deploy $version to atomically switch to a well-known version. Longer version: The awesome Cockpit project has been working on a UI for managing Atomic Host/OSTree updates. See this page for some background…

Cutting out the Middleman, with WordPress
For the past few years, the only posts I’ve written in this blog have been about this blog, and this post is no different. I make up for it in lack of volume: I’m averaging about one post a year. Two years ago, I wrote about how I’d finally (almost) gotten my static blog all…

Clustering Atomic Hosts with Kubernetes, Ansible, & Vagrant
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…

Running a Containerized Cockpit UI from Cloud-init
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…
