What is zeropod? A little less than a year ago, I published a first article , reviewing a tool called zeropod. Zeropod is a Kubernetes runtime (more specifically a containerd shim) that automatically checkpoints containers to disk after a certain amount of time of the last TCP connection. While in scaled down state, it will listen on the same port the application inside the container was listening…
TL;DR This is a bit old now, but I still wanted to share a quick write-up on the topic. Back in January, a cybersecurity researcher reported a Kubernetes flaw that generated quite a buzz. It had been a while since we had a Kube vulnerability that got people talking this much, at least from Denis’s memory (yes, I talk about myself in the third person). Honestly, it’s pretty wild: the…
The infographic that triggered me Note: I stumbled upon this GenAI infographic and it was so bad I wrote a post about it. I didn’t generate this thing. Over the past few days, LinkedIn has been flooded with the same kind of infographic. Kubernetes 1.36 is out, and one of the most talked-about features is the GA release of UserNamespaces . It’s a topic I’ve been following since…
Previously, on “GenAI and dev” In my previous article , I talked about my experience with PodSweeper, a project developed with OpenCode and Claude Opus. The outcome was mixed: impressive raw speed, but race conditions, lax error handling, and a constant need for human supervision (among other disappointments). Today, I’m talking about a second project, much simpler, born from a…
Flannel, flannel, flannel… Flannel is a simple and popular CNI 😢. It’s the default CNI in k3s, the one half the kubeadm tutorials use, and you’ll find it in quite a few managed offerings too. OK, it’s simple, it routes packets between pods, it supports VXLAN and WireGuard, it takes 2 minutes to set up. What more could you ask for? Well, exactly. There’s one thing…
GenAI, is it fantastic? Quite a few people have shared their takes on GenAI for development in a very short time, so I realize it’s more than time I post this draft I started over two weeks ago 🙃. For work, I use AI assistants more and more to help me with my daily tasks. In 2024, it was mainly for automating tedious tasks (scripting stuff, making a painful list of repetitive tasks without…
