![]() ![]() I have to say, after just one page, I’m not inclined to read the rest. They involve the kernel, but they are user-space tools in the end. While HAL is not core kernel innovation, neither are things like PAM or NIS. Lastly there is the fact that Linux has seen innovation: the best example of which is HAL, but which also includes things like Reiser (version 3 of which is in the kernel). I've been poking lately at Kolla, a project aimed at deploying and running OpenStack within a series of docker containers, all orchestrated by Kubernetes.So I’ve skipped ahead to the second page, and he’s going on an on about how rubbish Linux is because it’s not a micro-kernel, and therefore conservative, and therefore behind the times.Īnd then he goes on to talk about all Sun’s inventiveness, while failing to omit that Solaris is also monolithic.Īnd then he goes on about how much faster BSD development is, despite the fact that it started before Linux (albeit with a mid-stream re-write just as Linux was started in 1994), and omits the fact that in terms of performance and hardware support BSD is inferior to Linux. Once you get your hands on the Atomic hammer, every problem starts looking like an opportunity for containerization. Check out the new CentOS Atomic image article on the Project Atomic blog to learn more about the latest test release. I'm usually in that channel as jbrooks, so say hi if you drop in!įinally, if you're more into CentOS, there's an Atomic option for you as well. ![]() If you're into IRC, you can find Atomic fellows in #atomic on Freenode. If you're using virt-manager or another cloud-init-less option, check out the article Running Cloud Images Locally to learn how to roll your own ISO image-based cloud-init provider.įrom there, check out the Getting Started page over at Project Atomic as well as the Q&A site for the project. The Fedora Atomic image ships without a default password, relying instead on cloud-init to facilitate logging in. If you're using virt-manager or OpenStack, you'll want to download the qcow image. Head over to the Fedora download site and grab one of the For Containers images. I wrote a howto on the Project Atomic site for getting started with Kubernetes on Atomic. Kubernetes is a fairly young project, and as such, is somewhat rough around the edges and fairly fast-moving. Orchestration: Fedora Atomic includes Kubernetes for orchestration and management of its containerized applications. ![]() Management: Fedora Atomic also ships with a slick new web-based server management UI, called Cockpit, which exposes a range of basic services, storage, networking, and performance configuration options, as well as some really interesting controls over containers running on your host. ![]() If you're playing with Fedora Atomic and want to extend or otherwise modify its package set, I wrote a howto on the topic over at the Project Atomic site. System Updates: Like every other Fedora distribution, Fedora Atomic is built from RPMs, but thanks to a project called rpm-ostree, system updates are atomic either the whole set of updates applies, or none of them do, and Fedora Atomic automatically keeps the previous version of the OS available for rollback in case something doesn't work out as expected. If you're looking for examples of containerized applications to run, both the Fedora and CentOS projects maintain repositories of popular open source applications in containerized form. Fedora is now organized into three separate flavors: Workstation, Server, and Cloud.įedora's Cloud flavor is further divided into a "traditional" base image for deploying the distribution on your cloud of choice, and an Atomic Host image into which Fedora's team of cloud wranglers has herded a whole series of futuristic operating system technologies.Īpplications: Fedora Atomic is built to host applications in docker containers, which provide a simple-to-use means of getting at all the workload-hosting goodness that's built into Linux, but that tends to require some assembly. This week, Fedora 21 (a.k.a., the release that must not be named) hit FTPs mirrors everywhere, with a feature list led by a new organizational structure for the distribution. ![]()
