K3S and Rio on WSL2

README.md

Install Rio on K3S running in WSL2 on Windows

Info

• K3S is a certified kubernetes distro for edge and other scenarios
• Rio simplifies application development on kubernetes
• WSL2 run linux on windows, nicer and more integrated than a traditional vm on hyper-v

Prerequisites

• Windows 10 with WSL2 set as default

  wsl --set-default-version 2

• Docker for Windows installed. Used to create the WSL2 image.

Steps

• Open powershell
• Ensure you can run the next script by running:

  Set-ExecutionPolicy RemoteSigned -scope CurrentUser

• Run:

  iex (new-object net.webclient).downloadstring('https://gist.github.com/juliostanley/622486d82cb8ed334d270ead5f684e89/raw/445d8b336b68c98064d79603034ecd0ede38fbfe/install-k3s-rio-wsl2.ps1')

NOTE: If you are on a machine with 8GB of RAM or less. You should prob use a config similar to this. Set it at ~/.wslconfig, WSL2 will return RAM only on some scenarios so for now its better to restrict it until it can do better.

Why are you using not latest k3s (FROM rancher/k3s:v1.17.0-k3s.2-alpha1-amd64 in liifi-wsl-k3s.ps1)?

I think latest tag was using to the old v1.0.1, v1.17.0-k3s.2-alpha1-amd64 is the latest, higher than v1.17.0-k3s.1 release. Using specific versions to keep things a little more reproducible.
