I love containers, it's really cool technology to preserve and distribute environments. To manage containers I prefer podman and its friends buildah and skopeo. podman 4 introduced many cool features but it's unavailable in Ubuntu 22.04 which is my primary OS, the latest version there is 3.4.4. Thus, I decided to backport podman from Debian Testing where it's already packaged by mighty Debian maintainers.

Recently I started my video blog on YouTube. To shoot videos I use DJI Action 2 camcorder. It can record videos up to 4K@60 FPS. Obviously, resulting video files are heavy for editing and rendering. Are there solutions on Linux that help you to work with modern high definition video? The answer is yes and here is my approach.

I faced with broken add-apt-repository on my KDE Neon after upgrading to Ubuntu 22.04

After installing some Flatpak package on my KDE Neon the application icon was not displaying neither in the window header nor in the panel. I wanted to fix it and discovered that is related to zsh package. Here is my troubleshooting path.

I work with Linux containers and container images everyday. I often create new images using podman or buildah. One day I needed to build a custom image of a virtual machine and in this post you'll read how I did it.

Containers are de facto a standard way to distribute services and software. It's convenient to have preconfigured environment that can be activated on any machine that has a container engine such as docker or podman. UI testing with Selenium requires certain environment including browsers, X server and a window manager. It would be nice to have all of these packed into a one container image.

Gitlab CI doesn't have built-in support of Openstack but provides the API to add such support via Drivers. In this post I'll demonstrate how to create such drivers.

Using Gitlab CI, Openshift and S2I technologies you can create a pipeline for building and deploying static websites.

Managing user services by systemd in Github Actions runners is not so obvious as in your local machine. Here is what I found when I was trying to start rootless podman as a service.

In unit testing we often mock various objects, libraries and side effects. For example it can be a response from some web service. But what should we do in integration and functional tests?
