Mon cheminement pour autoscaler un cluster OVH déployé via la Cluster API, en utilisant Karpenter et son provider cluster-api, avec MKS comme cluster de management.

Tu as un homelab Proxmox, tu as entendu parler de Talos Linux et de Cilium, tu as même développé ton propre module Terraform pour automatiser tout ça. Mais entre le moment où tu te dis “je vais créer un petit cluster K8s” et le moment où tu as un cluster fonctionnel avec kubectl get nodes, il y a tout un chemin de commandes à taper, de fichiers à éditer, de tokens à générer.

I created and maintain Luxury Yacht, a desktop app for managing Kubernetes clusters. Think Headlamp, Lens, and k9s. It's that kind of app. Luxury Yacht is a ...

Recently, a friend of mine asked me what resources I'd recommend to start learning about Kubernetes. He was a victim of the layoffs that seem to be so prevalent right now and has experience as a classic SysOps / SysAdmin engineer but no expose to Kubernetes yet and wanted to learn to help improve his job-hunting prospects.
I wasn't sure what to recommend at first, it's been a long time since I was learning Kubernetes for the first time and wasn't sure what was still useful and relevant but what follows is what I ended up sharing with him, and now with all of you.

So I've been job hunting lately. Reading job postings, doing interviews, talking to engineering teams at like a dozen companies. And I noticed...

I've used Kubernetes for years, and it was time to make the TUI suitable for me. Inspired by k9s and lens.

L’infographie qui m’a trigger Depuis quelques jours, les infographies se suivent (et se ressemblent) sur Linkedin. Kubernetes 1.36 est sorti et une des features qui fait le plus parler, c’est la sortie en GA des UserNamespaces.\nC’est un sujet que je suis depuis 2018 (talk The Route to rootless container à la kubecon EU de 2018) donc je peux dire que je suis content de voir l’aboutissement de ce long chemin. Cependant, je suis “profondément choqué” de voir la façon dont c’est présenté sur LinkedIn, visiblement par des gens qui n’ont aucune idée de comment ça fonctionne (et qui probablement, s’en fichent).\n

XO 6.4 is out: RBAC/ACL v2 arrives in the REST API, better MCP support, XO 6 gains more XO 5 features, plus Kubernetes CSI v0.2.0 and new DevOps updates.

I recently ran into a claim: Docker Compose is outdated and K3s is the king for my 1Gb VPS. At the same time, docker-compose.py is effectively deprecated, with Compose now shipped as a built-in docker compose command. That alone is not a problem, but it raised a reasonable question: has the role of Docker Compose actually changed, or is this just noise from the Kubernetes church?

✳️ IntroductionWith the release of VMware Cloud Foundation 9 (VCF 9), VMware has introduced a major architectural evolution—consolidating Day-2 operations, automation, and lifecycle tasks into VCF Operations (VCF OPS).One of the most notable changes is how Workload Domains (WLDs) are created. Previously, administrators used the SDDC Manager GUI to provision a new WLD. In VCF 9, this process now happens exclusively through VCF OPS, offering more flexibility, automation, and integration with moder

Introduction K8s is already a crucial part in the VMware ecosystem for many years and the level of integration in other products like NSX and AVI changed a lot in the past. That is also true for the naming like “vSphere with Tanzu”, “vSphere IaaS” and “VKS” and perhaps more changes in the future. For this blog post we will bring some spotlight to the integration for VKS with NSX VPCs, which is from my point of view a great enhancement from tenancy point of view.
