Podman is the daemonless, rootless drop-in replacement for Docker. Furthermore, you can manage containers on a remote machine without connecting to it first. With Podman's remote capabilities, this is just a matter of configuration files.
Ansible is easy, simple, and powerful, right? Sure, and it is a pain to get it right. There are various tools that are meant to help you with Ansible. Let's take a look at Steampunk Spotter, a quality assurance tool, that makes it easy to improve your Ansible playbooks, roles, and collections.
Are 6 months already over? It feels like yesterday that Fedora Linux 38 was released. Well, the new release looks really promising. We are finally having an option to boot without GRUB, Modularity is ceased, Linux Kernel 6.5 and much more.
Working in a DevOps world means, that everything is automated, fully tested, made in one team, …, right? Well, no. It means that we are having a culture, that supports DevOps approaches. But it also means, that we are having a couple of conflicts, that need to be solved.
It's finally time for my very first programming article. In the past, you have seen articles about Ansible, Podman and Linux, mostly. But what about making your own program? In this article, we will get started with Go.
Right after the release of the Raspberry Pi 5, we are getting a new Raspberry Pi OS, based on Debian Bookworm. It features some pretty interesting changes on the Desktop, but also got nice features for the Lite variant.
Ansible is a simple, yet proven way to automate your server configuration, cloud deployments and many other things. Yet, most people know Ansible on the command line, which is perfectly fine for CI/CD or if you like to work with text.
About a year ago, I received my Steam Deck and wrote an article about the first impressions. The Valve Steam Deck is a nifty gaming console, running on Steam OS (based on Arch Linux). It comes in a portable gaming console format and should make it easy to carry your steam library around.
Podman is the rootless drop-in replacement for Docker, but how do you administer Podman containers, images and more with the browser? Let's check out Cockpit and Podman application for it.
Two days ago (28th September 2023), the Raspberry Pi foundation announced the new Raspberry Pi 5. The device should feature double the speed with the new RP1 chip and will be available in for pre-order right now.
When it comes to DevOps, most people think of cloud, containers, CI/CD and automation. Well, this is true to some degree, but these are only tools. One of the underlying fundamentals is a proper lifecycle.
Yesterday was the Ansible Community Day in Berlin. I have to say, it was a blast. Meeting the community, talking about all kind of tech-thingies (technical term) and connecting with experts is something I really enjoy.
Ansible can trigger tasks based on the execution of other tasks. This feature is known as handlers or notifies. Many examples use this feature in the most minimal way possible, and therefore the power of handlers is pretty much unknown.
With the latest changes at Red Hat another wave pushed through the world of Open Source. Finally, the dust has settled a bit. In this article, I want to take a look at these changes, discuss if Red Hat is evil and how we might continue from here.
In the last part of "Ansible - Collection", I talked the reason and usage of collections. Now, let's see how you can create your own collection. Believe me or not, this is easier than creating a bunch of roles and playbooks like it was done in the past.
There is this myth of the 10x engineer/worker. It's somebody who can deliver as much as 10 others. This engineer gathered knowledge and developed skills to outperform everybody. Well, the 10x engineer might be a myth, but there are -10x engineers for sure!
Ansible
In the past, and especially on the Chemnitz Linux Days, I was asked about Ansible Collections, a lot. It seems like this topic is somewhat complicated and still unknown. Let's take a look at collections, build one, and showcase how it can make your development easier than ever.
Development
Git is ruling the development world like no other. At some point, you may find photos, diagrams or other documents in your code, to keep track of them. But, is it really ok to store large files or even binaries in your code?
Podman
The world of containers consists of images, which are made out of layers. Normally, everybody with access to the image can investigate it, check out what's in there and how it works. Encrypting your images can prevent others to see the content of your images, even if they get access to it.
DevOps
My last DevOps article was published 3 months ago, so I assume it is time for another one. The last time, we had a look at ideals – things you will never reach, but always aim for. Now, let's have a look at principles – things you can apply to work towards ideals.
Linux
Over the weekend, I discovered something for my theming demands. I was eagerly looking for a pastel/cozy look for my desktop. Catppuccin ticks so many boxes for me that I really want to share with you.
Security
In the last part of this article, we installed GPG and created our first keys. For this part, let's have a look at sub-keys and renews. Afterward, you should be set up to use GPG for upcoming tasks like container image encryption, Git commit signing or E-Mail signatures.
Release
I am back to writing. And my first article should be about the brand new Fedora 38 release. What's new? What's hot? Let's have a look why this release is boring, but way too impressive to not write about it.
IoT
When it comes to IoT/Edge computing, you have to consider one very special paradigm: "Everything is pull-only". Ansible and Podman can make this work, and we can build a device, that is configured via a Git repository.
Security
After setting up the framework for our security series, we will finally have a look at the first security improvements. What can we do, to avoid that somebody physically compromises our hardware? And what does this even mean?
Security
The world is full of signing and encryption methods. There is one, that is especially useful in Open Source software. GPG can be used to sign mails, Git commits, container image encryption and much more. Let's set it up!
DevOps
If you say "DevOps", people will understand "Kubernetes", "Ansible" or "Cloud", most likely. But, the true nature of DevOps is a cultural change, based on 5 major ideals. Let's dig into these and explain, how they can change your way of working, more than JIRA or Scrum ever did.
Kubernetes
In some past articles, I talked about Kubernetes and how to get started. Minikube is awesome for local development, but what about Kubernetes on small environments? k3s is one of the easiest ways to deploy and run a Kubernetes instance, which can also be used to create high available clusters.
Security
I did some polls and surveys recently, which indicated that security and hardening might be important issues for some of you. This article marks the start of a series about these topics.
Spotlight
There was a time when the internet was young, full of enthusiastic people that wanted to connect others. We became the product. Our data is used to sell ad-placements. Are there alternatives?
Fedora
Our home server can host a couple of applications now. But, remembering the different addresses, ports, and services seems somewhat wrong. In this article, we will solve this situation by deploying a dashboard, that provides links to all our applications.
DevOps
The last DevOps article was in September. So, it might be time for more DevOps stuff. Don't you think so? Let's have a look at different work types, that one needs to understand establishing a DevOps culture, either for your own work or your company.
