Obsolete notice

This document was created back in 2020 and might not be actual nowadays. It is not supported anymore, so use thise information at your own risk.
Upgrading to WSL 2


Download WSL2 Kernel
run wsl --set-default-version 2 in windows command line, so that all future WSL machine will use WSL2.

Installing Arch Linux

Basic installation


Download ArchWSL installer zip, pick a folder (for example, c:\archlinux) for Arch Linux and run installer .exe in that folder.

Initialize package manager


Add custom pacman repository with additional packages: nano /etc/pacman.conf Then add following to the bottom:

[archlinuxfr]
SigLevel = Never
Server = http://repo.archlinux.fr/$arch


Refresh Pacman GPG keys:

pacman-key --init
pacman-key --populate
pacman-key --refresh-keys
pacman -Sy archlinux-keyring


Run pacman -Syyu to update all packages to the latest versions

Install zsh, optional


Install zsh: pacman -S zsh

Create a user


Add a sudo group: groupadd sudo
Enable sudoers: nano /etc/sudoers and uncomment lines %wheel ALL=(ALL) NOPASSWD: ALL and %sudo   ALL=(ALL) ALL
Add new admin user: useradd -m -G wheel,sudo -s /bin/zsh <username>, use -s /bin/bash if you want bash instead of zsh.
Set password for the new user: passwd <username>
Run Windows command shell, go to the directory with Arch Linux, run Arch.exe config --default-user <username>. Now you have basic ArchLinux with user.

Install AUR helper


Just follow How to Install Yay AUR Helper in Arch Linux and Manjaro guide:
sudo pacman -S git openssh
sudo pacman -S base-devel - when asked question on fakeroot and fakeroot-tcp choose to leave fakeroot-tcp and not install fakeroot
git clone https://aur.archlinux.org/yay-git.git
cd yay-git
makepkg -si
Run yay -Syu to update all AUR packages and reinstall fakeroot-tcp (will install the latest version)
Remove the leftovers: rm -rf ~/yay-git

Goodies


Install useful console tools: sudo pacman -S mc wget htop pv ccze

Preserving config files from previous WSL installation

Copy .ssh, .kube, .aws from original installation home directory to the Arch WSL2 one.
Fix file permissions for SSH keys, run from the home directory:
chmod 0644 .ssh/id_rsa.pub
chmod 0600 .ssh/id_rsa

Installing additional software

Install Kubernetes

sudo pacman -S kubectl kubectx
Install Docker

Uninstall Windows docker to prevent potential naming conflicts.
sudo pacman -S docker docker-compose
Use wsl2-docker-start scripts to run docker exposed to Windows:
git clone git@github.com:imjonos/wsl2-docker-start.git
cd wsl2-docker-start
chmod +x docker-start prepare-hosts
sudo cp docker-start prepare-hosts /usr/local/bin

In Windows you should make sure C:\Windows\System32\drivers\etc\hosts file has write access for your user.
Always run docker in a dedicated terminal tab using docker-start
ld100 dotfiles & zsh config

git clone https://github.com/ld100/dotfiles.git ~/.dotfiles
zsh ~/.dotfiles/install.sh

Install programming languages

sudo pacman -S ruby nodejs python go crystal php jre-openjdk-headless
Installing protocol buffers

Main binaries/libraries: sudo pacman -S protobuf protobuf grpc grpc-cli
gRPC for Python and PHP: sudo pacman -S python-grpcio php-grpc
gRPC & Protobuf for Go: yay -S protobuf-go protoc-gen-go-grpc
gRPC & Protobuf for Ruby: gem install google-protobuf grpc grpc-tools
Setting ArchLinux as default WSL

Just run wsl --set-default Arch in windows command shell.
Accessing WSL from Windows

All WSL machines are available in Windows Explorer on \\wsl$\ URL, Arch linux is: \\wsl$\Arch.
For additional convenience you could map \\wsl$\Arch to a 1-Leter Windows disk share, for example having Z:\ pointing to \\wsl$\Arch
