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).
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.
DIY
This year, I started a very special project for me. During the last couple of years, I tried many keyboards and there was always something. It was too big, too loud, the keyboard layout was odd or whatever. So, I decided to build my own keyboard.
Fedora
In the last article, we created a Git server, running in Podman. The deployment was done with Ansible. The article before was about some central infrastructure. This time, let's see how we can have our own File, Calendar, and Contact sync. Yes, we will deploy Nextcloud!
Fedora
Our Home Server is doing some nice stuff already. With the last articles, I want to demonstrate how you can deploy some useful applications on it. Running your own Git server has some advantages, when it comes to private work or testing.
Fedora
With the release of Fedora Linux 37, I switched back to Fedora Silverblue. I took this opportunity to revamp my Fedora Workstation repository and therefore my Ansible playbook for the same.
Fedora
In the last article of our Home Server series, we tackled the deployment of a timeserver. This also provided us with some useful tooling to set up more container deployments. Let's continue on this approach and tackle DNS and DHCP.
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.
