eBPF Verifier: Why the Kernel Can Safely Run eBPF Programs
In this tutorial, you’ll learn why it is safe to run eBPF code in the kernel, some of its advantages compared to kernel modules, and why the verifier is the most crucial component of eBPF.
Building an eBPF/XDP NAT-Based Layer 4 Load Balancer from Scratch
Learn how an eBPF/XDP-based NAT Layer 4 load balancer works by building one from scratch. We implement simple connection tracking, deterministic hashing, and IP/MAC rewriting with a small, easy-to-follow example.
How (and Why) to Use containerd from the Command Line
Explore containerd with ctr, its default command-line client, try nerdctl as a potential Docker alternative, and learn how to debug Kubernetes Pods with crictl.
