Just a guy doing stuff. Mostly #FLOSS like #Linux, #Ansible, #Podman, #k8s, #Python, #Nextcloud or whatever comes next. You can also find me on Mastodon (https://fosstodon.org/@dschier).
Bash
The customization of a prompt is very often just some "optical enhancements". Some colors here and maybe some behavior there. If you want to have additional functionality, you may want to have a look at Starship. A blazing fast prompt with lots of cool features.
Cloud-Init
If you read my blog carefully, you may know that I really like Ansible. You can manage and configure machines and APIs very easily with Ansible automation. But what if the machine is offline or needs a configuration to boot up? This is where Cloud-Init can help.
Ansible
In the previous part of this article, we had a look at Ansible Roles and how you can use them. Now, let's develop a role on our own. It's really a piece of cake.
Fedora
In the previous article, we introduced virtualization to our home server. This allows us to start virtual machines with different operating systems. The combination of libvirt, KVM and Cockpit also allows us to create virtual machines with a graphical frontend.
Fedora
Virtualization opens a wide variety of possibilities. If you want to test a new OS release or set up some special workload, a Virtual Machine can be used easily.
Fedora
On Tuesday 03.05.2022, Fedora Linux 36 will be released, and I really want to give a brief overview of what's new and what changed. Since I haven't done a GNOME 42 release article, I will cover some included changes here, too.
Container
Building your own containers is very easy and fast to learn. But very soon, you may end up with large container images and no idea how to reduce the footprint. Since you need to download and store each image, it can be useful to minimize the images, and this article will address exactly this.
Ansible
Let's do Ansible, they said. Writing simple playbooks is easy, they said. But, should one really write playbooks over and over again? Repeat yourself? Not at all, for sure. Automation is about avoiding repetition, and Ansible has some concepts to address this.
Podman
Over the last weekend, I was hanging around in the Podman Matrix chat and was seeing lots of conversation regarding Podman and Docker Compose. So, let's dig into Podman Compose and why you don't need a Kubernetes Cluster/Instance for Container orchestration.
Linux
Concept done, Hardware done, started with automation and now? Sure, we want to make the new home server manageable. I want to see errors, updates, performance data at a glance and configure some minor things ad-hoc. This article is exactly about this addition to our home server.
Fedora
Fedora is constantly evolving and changing how the GNU/Linux world is looking like. One of the more recent approaches is Fedora Silverblue. The immutable Desktop Linux has the potential to become the new Fedora Workstation Linux. Shall we have a look?
Linux
In some previous articles, we covered the GNU/Bash and adjusted it to our liking. But you can do even more. Powerline-Go is an awesome way to make your GNU/Bash prompt more useful and beautiful.
Kickstart
Everybody who wanted to deploy a bunch of GNU/Linux machines at the same time was facing the same problem. Do I really want to click through the initial installer? Isn't there a better way? This article will demonstrate how Kickstart can be used.
Home
In the Fedora - Home Server series, we are looking into setting up and automating our Home Server deployment. The last two articles introduced you to the concept, hardware and operating system. This time, we will set up our automation and do the first tasks.
Kubernetes
In the last article, we were starting with Kubernetes and talked about the basic concepts, namespaces and pods. For this article, we will have a look at deployments, ingress and service objects.
Kubernetes
Kubernetes, the software that is often referred to as the operating system for application development. It's true, Kubernetes changed a lot in the application development world. But what are Deployments, Ingress, Service or Namespaces?
