My Dotfiles

Goals of this setup

• Working on Windows 11, on WSL 2 filesystem
• Having a visually nice terminal (Windows Terminal)
• Zsh is my main shell
• Using Docker and Docker Compose directly from Zsh

What's in this setup?

• Host: Windows 11
  • Ubuntu via WSL 2 (Windows Subsystem for Linux)
• Terminal: Windows Terminal
• Systemd
• zsh
• git
• Docker
• Docker Compose
• Node.js (using Volta)
  • node
  • npm
  • yarn
• Go
• WSL Bridge: allow exposing WSL 2 ports on the network

---

Setup WSL 2

• Enable WSL 2 and update the Linux kernel (Source)

# In PowerShell as Administrator

# Enable WSL and VirtualMachinePlatform features
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

# Download and install the Linux kernel update package
$wslUpdateInstallerUrl = "https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi"
$downloadFolderPath = (New-Object -ComObject Shell.Application).NameSpace('shell:Downloads').Self.Path
$wslUpdateInstallerFilePath = "$downloadFolderPath/wsl_update_x64.msi"
$wc = New-Object System.Net.WebClient
$wc.DownloadFile($wslUpdateInstallerUrl, $wslUpdateInstallerFilePath)
Start-Process -Filepath "$wslUpdateInstallerFilePath"

# Set WSL default version to 2
wsl --set-default-version 2

• Install Ubuntu from Microsoft Store

Install common dependencies

#!/bin/bash

sudo apt update && sudo apt install -y \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common \
    git \
    make \
    tig \
    tree \
    zip unzip \
    zsh

GPG key

If you already have a GPG key, restore it. If you did not have one, you can create one.

Restore

• On old system, create a backup of a GPG key
  • gpg --list-secret-keys
  • gpg --export-secret-keys {{KEY_ID}} > /tmp/private.key
• On new system, import the key:
  • gpg --import /tmp/private.key
• Delete the /tmp/private.key on both sides

Create

• gpg --full-generate-key

Read GitHub documentation about generating a new GPG key for more details.

Setup Git

#!/bin/bash

# Set username and email for next commands
email="[email protected]"
username="rickytang"
gpgkeyid="8FA78E6580B1222A"

# Configure Git
git config --global user.email "${email}"
git config --global user.name "${username}"
git config --global user.signingkey "${gpgkeyid}"
git config --global commit.gpgsign true
git config --global core.pager /usr/bin/less
git config --global core.excludesfile ~/.gitignore

# Generate a new SSH key
ssh-keygen -t rsa -b 4096 -C "${email}"

# Start ssh-agent and add the key to it
eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa

# Display the public key ready to be copy pasted to GitHub
cat ~/.ssh/id_rsa.pub

• Add the generated key to GitHub

Setup zsh

#!/bin/bash

# Clone the dotfiles repository
mkdir -p ~/dev/dotfiles
git clone [email protected]:rickytjx/dotfiles.git ~/dev/dotfiles

# Install Antibody and generate .zsh_plugins.zsh
curl -sfL git.io/antibody | sudo sh -s - -b /usr/local/bin
antibody bundle < ~/dev/dotfiles/zsh_plugins > ~/.zsh_plugins.zsh

# Link custom dotfiles
ln -sf ~/dev/dotfiles/.aliases.zsh ~/.aliases.zsh
ln -sf ~/dev/dotfiles/.p10k.zsh ~/.p10k.zsh
ln -sf ~/dev/dotfiles/.zshrc ~/.zshrc
ln -sf ~/dev/dotfiles/.gitignore ~/.gitignore

# Create .screen folder used by .zshrc
mkdir ~/.screen && chmod 700 ~/.screen

# Change default shell to zsh
chsh -s $(which zsh)

Docker

Setup Docker

#!/bin/zsh

# Add Docker to sources.list
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# Install tools
sudo apt update && sudo apt install -y \
    docker-ce docker-ce-cli containerd.io

# Add user to docker group
sudo usermod -aG docker $USER

You can start the Docker daemon via Systemd or via dcs alias.

Docker Compose

#!/bin/zsh

sudo curl -sL -o /usr/local/bin/docker-compose $(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep "browser_download_url.*$(uname -s | awk '{print tolower($0)}')-$(uname -m)" | grep -v sha | cut -d: -f2,3 | tr -d \")
sudo chmod +x /usr/local/bin/docker-compose

Node.js

#!/bin/zsh

# Install Volta
mkdir -p $VOLTA_HOME
curl https://get.volta.sh | bash -s -- --skip-setup

# Install node and package managers
volta install node npm yarn

Go

#!/bin/zsh

goVersion=1.16.4
curl -L "https://golang.org/dl/go${goVersion}.linux-amd64.tar.gz" > /tmp/go${goVersion}.linux-amd64.tar.gz
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf /tmp/go${goVersion}.linux-amd64.tar.gz
rm /tmp/go${goVersion}.linux-amd64.tar.gz

See official documentation

Setup Windows Terminal

• Download and install JetBrains Mono
• Install Windows Terminal

#!/bin/zsh

windowsUserProfile=/mnt/c/Users/$(cmd.exe /c "echo %USERNAME%" 2>/dev/null | tr -d '\r')

# Copy Windows Terminal settings
cp ~/dev/dotfiles/terminal-settings.json ${windowsUserProfile}/AppData/Local/Packages/Microsoft.WindowsTerminal_8wekyb3d8bbwe/LocalState/settings.json

WSL Bridge

When a port is listening from WSL 2, it cannot be reached. You need to create port proxies for each port you want to use. To avoid doing that manually each time I start my computer, I've made the wslb alias that will run the wsl2bridge.ps1 script in an admin Powershell.

#!/bin/zsh

windowsUserProfile=/mnt/c/Users/$(cmd.exe /c "echo %USERNAME%" 2>/dev/null | tr -d '\r')

# Get the hacky network bridge script
cp ~/dev/dotfiles/wsl2-bridge.ps1 ${windowsUserProfile}/wsl2-bridge.ps1

In order to allow wsl2-bridge.ps1 script to run, you need to update your PowerShell execution policy.

# In PowerShell as Administrator

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
PowerShell -File $env:USERPROFILE\\wsl2-bridge.ps1

Then, when port forwarding does not work between WSL 2 and Windows, run wslb from zsh:

#!/bin/zsh

wslb

Note: This is a custom alias. See .aliases.zsh for more details

Limit WSL 2 RAM consumption

#!/bin/zsh

windowsUserProfile=/mnt/c/Users/$(cmd.exe /c "echo %USERNAME%" 2>/dev/null | tr -d '\r')

# Avoid too much RAM consumption
cp ~/dev/dotfiles/.wslconfig ${windowsUserProfile}/.wslconfig

Note: You can adjust the RAM amount in the .wslconfig file. Personally, I set it to 8 GB.

Install kubectl

#!/bin/zsh

sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg
echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubectl
