Open Source is more than just some cost-free software, where you can read the code. This category is about Open Source in general, tools, software, news, movements and Open Source projects.
Podman
When it comes to development of applications and container deployments, Docker is still considered the standard. VSCode provides several extensions to make your life with containers easier. But, the Docker and Dev Container extensions can be tuned to work with Podman, too.
Fedora
Fedora has just released Fedora Linux 37 after some delays. This release marks some very awesome improvements like Kernel 6.0.0 and GNOME 43. Let's have a look. This release also marks my "back to Silverblue" release and I will update you in one of the next articles.
Fedora
Now that Fedora 37 is in reach, I want to introduce a very special variant to you. Fedora Kinoite is KDE on Fedora, but in an immutable, container centric way. Let's shed some light on "Fedora Silverblue, but with KDE".
Development
Using Git is very common among developers nowadays. But, how do you work together on Git? What is the best strategy when it comes to discussions about trunks, mono-repos and what-not? Well, let's dig into this.
Linux
Last month, I have given a class about Raspberry Pi programming. It was awesome, and I really like to help others understanding new things. To my surprise, some attendees weren't having any idea about Linux commands at all. We often forget, that some of us are just starting their journey.
Home
Phew, that took a while to get right. I don't want to waste any more of your valuable time. So, let's dig into the deployment of a time, DHCP and DNS server on our home server. Shall we?
Fedora
Running Fedora comes with a new release every 6 months. Furthermore, you are having a somewhat short maintenance time of ~13 months, only. This means, that you need to upgrade your Fedora installation occasionally. Let's see how you can do this.
Ansible
Let's assume you have a playbook, but you want to use different values for your variables for each time you run it. For example, you want to create a new user on your machines or change the playbook behavior. This can be done, and it is very easy with Ansible Prompts.
KVM
In some past articles, we tackled KVM and libvirt as a virtualization option on Linux. But I never introduced the basics for the same. Therefore, let's have a look at KVM and libvirt on Fedora and see how you can get started.
Podman
If you want to use containers, you need to pull images from a container registry. This is the place where container images live. But, how do you run your own registry? For your local network or development purposes, this is really useful!
Gaming
When it comes to gaming, Linux is somewhat behind other platforms. This does not mean, that you cannot play a game on Linux, but there are limitations. This changed a lot with the introduction of Steam Deck. I got mine 2 weeks ago and want to share my first experiences with you.
Fedora
In the last articles we tackled virtualization, which is perfectly fine, if you want to run full-fledged virtual machines. On the other hand, you can use containers to deploy workloads very easily. So, let's have a look how we can integrate this in our home server.
Podman
It may be a surprise to you, but I am a huge fan of Podman. Recently, there is lots of development for Desktop integration, but there are also graphical tools for the browser or Command Line. If you want to manage your images and containers with in a graphical way, this article may be for you.
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.
