We are stress testing @slack.dev at work by starting a thread where we discuss the weather in the UK. 🫠

Tinkerer extraordinaire 👨🔧 mainly eBPF 🐝, Kubernetes, Cilium and kube-vip.io
Join Nico Vibert and Dan Finneran this Friday for a for a sneak peek at a lab demonstrating how #Tetragon can protect against an #OpenClaw agent trying to access or share private data. #eBPF & #Cilium Office Hours 📆 Friday, May 8, 9am ET / 3pm CEST 📺️ Join live: www.youtube.com/watch?v=G2R3...
So initially I started writing a service mesh (for fun), then everyone started talking about AI workloads. So here we are, a transparent gateway that can be applied to running workloads (no restart) that allows control between agents/workloads and an LLM. kube-gateway.io
When Heptio was acquired by VMware we had to give up our downtown Seattle office. We had just gotten a new light up sign for the reception and no one wanted it so it has been sitting in my garage for the past 8 years. I have space now so just hung it up and it is magnificent.
I love it when a plan comes together. Some years ago I sketched on how I would automatically join bare metal nodes to my k8s cluster with PXE and auto issued certificates. Today I wanted to add a node and I just had to update versions and it went well. #kubernetes #homelab youtu.be/Jr4AWyzDJPg

Docker can now run workloads inside a VM, we have now gone completely full circle at this point. 🫠

I am two people. - One, doesn't like to implement too much logging in my applications to make things clearer. - Two, the one who has no idea why my application behaves that way.. because the logs don't report anything.
This Friday, join Nicolas Vibert and Daniel Finneran as they talk through the key trends 2026 will bring in #Kubernetes networking, security, and #eBPF! eBPF & Cilium Office Hours 📆 Friday, January 23, 3pm CET 📺 Join live: www.youtube.com/watch?v=xBex...
Existing AI workloads? A few annotations and I can now transparently change their behaviour, swap out models in their API calls and more. (Thanks to #eBPF)

Re-found the virtual machine manager project for Kubernetes from last year, this example has BeOS inside a kubernetes cluster ssh-ing out to the control plane to manage itself 😂. No CNI needed either thanks to eBPF.
Regardless of what the AI client is (GO, Python etc...) we can now ensure we jump in to the "existing" data path and manipulate any of the data in either direction 😀
Using eBPF 🐝 and some proxy magic 🪄 to change the model on the fly transparently to the AI workload. We can see the first responses from llama and subsequent ones from gemma (more emojis).
Two pods with their traffic being proxied (thx eBPF 🐝) through a gateway, one using kTLS and the other user-land TLS. 🔐

Had a few bits of @kube-vip.bsky.social clothing made 🐙. All of it make me look like I work for a fish mongers. 🫠
Make egress traffic look like ingress allowed Loophole Labs leverage XDP to 12x the throughput of iptables, and all without kernel patches 📈 eBPF is freedom to rethink how the kernel works.
Using XDP for Egress Traffic
XDP only works for ingress. We found a loophole that lets it work for egress. Here's how we did the impossible.

An eBPF Loophole: Using XDP for Egress Traffic XDP is Linux's fastest packet processor but only handles incoming traffic. We found a loophole in how the kernel determines packet direction to make it work for outgoing traffic too! Blog post with details 👇 loopholelabs.io/blog/xdp-for...

Managed 25 minutes in this thing before I was starting to overheat 🥵
