A Random Walk Down Tech Street

Converting Butane to Ignition on Boot We’ve received anecdotal evidence over the years that the transpilation step where you must convert a Butane YAML configuration into Ignition JSON before staring your CoreOS instance is a pain for users to understand…

Problem Sometimes you just don’t have a stable (or even functioning network) to leverage when dealing with a piece of hardware.

History It’s a new year and it has been 5 years since the last time I updated this blog post series.

Recently I looked into enabling and testing multipath on top of iSCSI for Fedora and Red Hat CoreOS.

Recently we switched our 9p filesystem usage in CoreOS Assembler to use virtiofs.

Earlier this summer I spoke at the Fedora 38 release party about Fedora CoreOS.

Someone recently asked me about locking down a bond to specific NIC devices within the machine.

Note: A more permanent version of this tutorial exists in the Fedora CoreOS documentation.

A couple of us recently gave an update to our Customer Experience team at Red Hat on the improvements that were made in Red Hat CoreOS for OpenShift 4.6.

Introduction I recently did a blog post series. showing how to get started with OpenShift OKD on Fedora CoreOS for DigitalOcean.

NOTE: The fourth post of this series is available here.

Introduction NOTE: The third post of this series is available here.

Introduction NOTE: The second post of this series is available here.

Introduction NOTE: The first post of this series is available here.

Introduction This blog post is the first in a series that will illustrate how to set up an OpenShift OKD cluster on DigitalOcean using the bare metal install documentation (user provisioned infrastructure).

If you’ve ever had a chance to “nerd out” with me much I’ve probably told you about at least one TUI that I use to make my daily work life easier.

Introduction With Fedora CoreOS we currently have two ways to do a bare metal install and get our disk image onto the spinning rust of a “non-cloud” server.

Introduction NetworkManager allows connections to be defined in a configuration file known as a keyfile , which is a simple .ini-style formatted file with different key=value pairs.

Introduction For some time now with virt-install (developed under virt-manager) you have been able to specify a kernel and initial ramdisk to start a VM with.

Setting Up For The Lab This lab uses a Fedora CoreOS image and several utilities (fcct, ignition-validate) to introduce a user to provisioning and exploring a Fedora CoreOS system.

History It’s almost 2020.

cross posted with this Project Atomic blog post TL;DR Fedora 29 will be End Of Life soon.

Introduction With Fedora CoreOS Ignition is being used to configure nodes on first boot.

Introduction This is an update to my previous post about easily testing PXE booting by using libvirt + iPXE.

History It’s 2019 and I’m just getting around to converting my desktop system to Fedora 29.

Update: A future post explains how to do this even easier without PXELINUX.

cross posted with this Project Atomic blog post Introduction This week we put out the first release of Fedora 29 Atomic Host.

Introduction Last time I talked about using rpm-ostree-bisect, a tool that I wrote to automatically bisect the history of an OSTree remote in order to find the exact commit when a problem was introduced.

Introduction Occasionally in OS land we’ll come across a bug that snuck its way into a build and has been in the wild for a while before anyone notices it.

cross posted with this Project Atomic blog post Introduction RPM-OSTree/OSTree conveniently allows you to rollback if you upgrade and don’t like the upgraded software.

Introduction Earlier this month I was lucky enough to attend the 2018 Fedora Infrastructure Hackfest.

Introduction In Fedora we are moving to a unified OSTree repo structure where there is a single OSTree repository that is the remote for all branches of Fedora (rawhide, branched, stable, etc).

cross posted with this Project Atomic blog post TL;DR Fedora Atomic Host (and derivatives) will now include the firewalld package in the base OSTree that is tested, delivered, and released every two weeks.

History I’m back again with the Fedora 27 edition of my Fedora BTRFS+Snapper series.

cross posted with this Project Atomic blog post Introduction This week we put out the first release of Fedora 27 Atomic Host.

Introduction Hosting your own Atomic Host OSTree can be useful from time to time.

Introduction In Part 4 of this series we learned about package layering and experimental features of atomic host OSTree mutations.

Introduction In Part 3 of this series we learned about rebasing, upgrading, and performing rollbacks on Atomic Host.

Introduction In Part 2 of this series we learned about configuring container storage on Atomic Host.

Introduction In Part 1 of this series we learned a little about the technology behind Atomic Host and how to interact with a deployed system.

Introduction In Part 0 of this series we helped get a Fedora 26 Atomic Host system set up for the rest of this lab.

Introduction While Atomic Host has been around since 2014 there are still a lot of people that aren’t as familiar with the technology.

cross posted with this Project Atomic blog post A new Fedora Atomic Host update is available via an OSTree commit: Commit: f6331bcd14577e0ee43db3ba5a44e0f63f74a86e3955604c20542df0b7ad8ad6 Version: 26.101 In this release we have fixed an issue with our qc…

cross posted with this Project Atomic blog post and this Fedora Magazine post Introduction In July we put out the first and second releases of Fedora 26 Atomic Host.

cross posted from this_ fedora magazine post Now that the Fedora Beta has been officially released the Fedora Atomic Working Group and Fedora Cloud SIG would like to get the community together next week to find and squash some bugs.

Cross posted with this_ Project Atomic Blog post TL;DR: The default Fedora cadence for updates in the RPM streams is once a day.

History I'm back again with the Fedora 25 edition of my Fedora BTRFS+Snapper series.

Cross posted with this_ Project Atomic Blog post Introduction In part 1 of this series we used the OpenShift Ansible Installer to install Openshift Origin on three servers that were running Fedora 25 Atomic Host.
