Instructions to hack up WSL2 on Windows 10 Build 18917 to run k3s (Kubernetes) and rio

Install WSL2

https://docs.microsoft.com/en-us/windows/wsl/wsl2-install

I already had Ubuntu-18.04 installed in wsl 1. So I just did wsl --set-version Ubuntu-18.04 2

Compile Kernel

Using Ubuntu 18.04 (I'm sure any distro will work), inside WSL2 download https://thirdpartysource.microsoft.com/download/Windows%20Subsystem%20for%20Linux%20v2/May%202019/WSLv2-Linux-Kernel-master.zip and extract to a folder. The latest version of the kernel source is available at (https://github.com/microsoft/WSL2-Linux-Kernel)

RKE2 commands

Updated on May 29 to accommodate etcd container not having /bin/sh available anymore.

Install

curl -sL https://get.rke2.io | sh
systemctl daemon-reload
systemctl start rke2-server

On the host

Ensure these modules are loaded

cat /proc/sys/net/bridge/bridge-nf-call-iptables

Disable swap

sysctl vm.swappiness=0
swapoff -a

Introduction

Installing kubeflow on localmachine is not a simple task. Documentation on the official website might be outdated. At the time of writing, the solutions suggested include miniKF and microk8s. The later sets up GPU passthrough effortlessly.

Install microk8s
Enable microk8s features

`k3s`/`RKE2` with external CRI/`containerd` support

While k3s and RKE2 ship with their own statically-compiled containerd binary, sometimes you need to be able to utilize a more standard container socket. Especially if your container-scanner expects a more traditional installation path (i.e. Twistlock/PrismaCloud). This quick guide will show you how to get up and running with an external CRI.

Install containerd

There are better ways to do this, but the most common way of installing containerd is via the docker-ce yum repository.

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
