WSL2 Custom Kernel Build Guide for Cilium with Rancher Desktop

Overview

This guide documents the complete process of building a custom WSL2 kernel with Cilium support and integrating it with Rancher Desktop's K3s distribution. The custom kernel enables full Cilium functionality including L7 proxy features, eBPF acceleration, and advanced networking capabilities.

Prerequisites

• Windows 11 22H2 or later
• WSL2 installed and updated to latest version
