Red Hat Certified Specialist in Containers

 January 20, 2026

Yesterday, I passed the Red Hat EX188 exam, which allowed me to renew my Red Hat Certified Specialist in Containers certification.

I had a very good memory of this exam from the last time I took it, so I was happy to go through it again. Different from last time, I did encounter some difficulties with the last exercise, which was a little surprising to me, since the last time I found it testing the same capabilities as a walk in the park, but maybe this time I simply started with the wrong foot. This obviously had no major impact on my exam, allowing me to easily achieve and exceed the required score to pass.

Upcoming Events: CEC, Flock, and DevConf.cz

 May 31, 2025

In the coming couple of weeks I’ll be heading to the Common Europe Congress (CEC2025), Flock 2025, and DevConf.cz 2025, some of the best community-driven events in the ecosystem. If you’re around, let’s catch up and share stories over coffee!

Common Europe Congress 2025 (Gothenburg, June 2–4)

The Common Europe Congress is the largest educational convention for IBM Power users in Europe. This year it’s taking place at the Gothia Towers in Gothenburg, Sweden. I’ll be there from June 2nd through the 4th, and I have two sessions lined up:

Route traffic across Podman networks with Traefik

 April 30, 2025

If you’ve followed my posts over the years, you know I prefer clean solutions to less clean ones for my home lab (more to come on this!). Over the past year, I settled on a pattern that gives me the isolation of Kubernetes Namespaces without any of its weight: one private Podman network per application, plus Traefik in a shared “DMZ” network that terminates TLS and forwards traffic where it needs to go.

Fedora on Scaleway Dedibox with bootc

 March 31, 2025

For a while now, I’ve been looking into optimizing and reorganizing some of the infrastructure that powers my self-hosting services. After evaluating a few alternatives, Scaleway’s Dedibox lineup caught my attention: it is a European company with good hardware and decent pricing.

However, as with every good solution, it is not perfect. Scaleway does not provide Fedora as an OS option for their Dedibox machines. They offer a decent selection, including Rocky Linux, Debian, and Ubuntu — but no Fedora. Now, if you know me, you know that Fedora is not just my distro of choice — it’s the one I trust for both personal and professional projects.

Upcoming Events: CentOS Connect, FOSDEM, and CfgMgmtCamp

 January 31, 2025

The next few days are shaping up to be packed with open-source goodness! I’ll be heading to CentOS Connect, FOSDEM, and CfgMgmtCamp, three of the best events in the ecosystem. These conferences always include a great mix of technical talks, hallway conversations, and spontaneous meetups with friends—both old and new.

If you’re around, let’s catch up!

• CentOS Connect (Brussels, January 31)
  Although the event run yesterday and today, I’ll only be able to attend today. CentOS Connect is a small but incredibly valuable event where the wider CentOS community (Fedora, CentOS, and all the Enterprise Linux distros) meets to discuss the space’s present and future. It’s a great opportunity to meet contributors, learn about upcoming changes, and exchange ideas with people who shape the CentOS ecosystem. I really like this event because its atmosphere is similar to Flock: very casual and more like a friends’ gathering than a conference.

Share volumes between Podman Systemd services

 December 31, 2023

Since the merge of Quadlet in Podman, I’ve been moving multiple services to Podman Systemd services. I find them to be easy to create, manage, and automate.

I recently migrated a complex system to Podman Systemd, where multiple processes write in a folder, and one process reads the folder’s content. Before the migration, everything worked properly since all the processes were running natively on the machine with the same user. After the migration, there were some permissions issues. This issue allowed me to dive a little more deeply into the whole implementation of SELinux for containers and realize a few interesting things.

Manage Podman containers with Systemd and Quadlet

 May 17, 2023

Until a few months ago, the only option to start containers from Systemd was to create a Systemd unit which called podman (or docker) with the run sub-command. Podman was also providing podman generate systemd to easily create such Systemd file.

This has now changed. From version 4.4 of Podman, in addition to the mentioned method, it is possible to use Quadlet to simplify the execution of containers from Systemd.

Quadlet allows you to create additional kinds of Systemd units to manage your container needs:
