If you want to name a single technology, every IT enthusiast should know, it will be containers. If you are into containers and want to learn about container technologies, you may love this section.
Linux
For me, running containers is somewhat bound to the command line. Yet, having a graphical environment allows discovering of dependencies and errors in a more intuitive way. Fortunately, we can check our Kubernetes, Distrobox and Podman containers with these nifty GTK applications, too.
Podman
Portainer is an application, providing a web UI for management of Docker and Kubernetes. It is simple, yet powerful, and easy to use. But, what about Portainer on Podman? In this article, I will give a quick guide, how you can get it running and start your first containers.
Podman
Have you built a container image on your workstation, just to find out that it doesn't work on your Raspberry Pi? Maybe your project considers publishing a software for arm64 and amd64, so your users can run it on different platforms? No worries, Podman got you covered!
Podman
Podman is the daemonless drop-in Docker replacement and has exceptional systemd support. With Quadlets, this support became even better and the hassle to work with systemd unit files is gone. It was never this easy to define your containers as systemd services.
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.
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.
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.
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.
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.
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.
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.
