I am Nicolas Massé, you will find me on social networks under the nickname “nmasse-itix”. Initially developer, I now work as pre-sales consultant in the fields of API Management, Single Sign On and Containers.
I mainly work with Open Source technologies such as Keycloak, 3scale or OpenShift. I share my expertise and interests on this site, as a guest on other websites and I occasionally give conferences.
Please read my blog or learn more about me.
After revealing the behind-the-scenes design of the Leaderboard for the “Open Code Quest” workshop during the Red Hat Summit Connect France 2024 , it’s time to delve deeper into its practical implementation! In this article, I’m going to take you through the configuration of Red Hat Advanced Cluster Management as well as the various adaptations needed to connect the Leaderboard created earlier with the Open Code Quest infrastructure. Come on board with me for this new stage, which is more technical than the previous one, as I had to get creative to wire up a very “conceptual” Grafana dashboard with the reality of OpenShift clusters!

At the Red Hat Summit Connect France 2024 , I led a workshop for developers entitled “Open Code Quest”. In this workshop, developers had to code microservices using Quarkus, OpenShift and an Artificial Intelligence service: IBM’s Granite model. The workshop was designed as a speed competition: the first to complete all three exercises received a reward. I designed and developed the Leaderboard which displays the progress of the participants and ranks them according to their speed. Was it easy? Well, not really, because I imposed a certain style on myself: using Prometheus and Grafana. Follow me behind the scenes of Open Code Quest: how I designed the Leaderboard! Continue reading
In March of this year, I decided to find a new server to host the family’s data (Jellyfin, Nextcloud, etc.), control the house with Home Assistant and run the VMs I need for my work. In this article, I detail my constraints and the construction of this server, based on an Ampere Altra CPU (ARM64 architecture). Continue reading
In 2022, I wrote an article on this subject named Build multi-architecture container images with Kubernetes, Buildah, Tekton and Qemu . The article described the configuration I had set up for my personal projects. It even went beyond its initial purpose as it has also been used by several colleagues at Red Hat who had the same need. While the configuration described in this previous article is still relevant, the approach is somewhat dated. With the increasing availability of ARM servers in the Cloud, I revisited the topic of building multi-architecture container images using the AWS cloud. Continue reading
ARM servers are becoming mainstream (Ampere Altra server, Raspberry Pi SoC, etc.) and people start using them with containers and Kubernetes. While official Docker Hub images are built for all major architectures, the situation is less clear for other Open Source projects. It is possible to acquire an ARM server and use it to build container images, but it puts an additional constraint on the Continuous Integration chain. This article explores another option: build ARM container images on a regular x86 server, using Kubernetes, Buildah, Tekton and Qemu. Continue reading
