Guides will help you to understand things and getting things done, you haven't done before. This section will provide a collection of our guide articles.
Podman
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.
DevOps
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.
Golang
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.
Ansible
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.
Podman
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.
Ansible
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.
Ansible
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.
DevOps
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.
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.
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!
