🔭 Overview

After a lot of trial and error, I've been able to piece together a pretty respectable Windows dev environment. While there are numerous guides available, I noticed a lack of comprehensive coverage. In this guide, I've aimed to provide a holistic overview without delving too deeply into specific topics, in the hopes of ensuring a seamless developer experience for the majority of users.

☑ Prerequisites

• Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11 (Which version do I have?)
• A GitHub account

🐧 WSL

The first and most important part of setting up your Windows dev environment is installing the Windows Subsystem for Linux (WSL). I recommend sticking with Ubuntu but feel free to try out as many distributions as you like. There are no issues with having multiple distributions installed at once.

Installing WSL 2

WSL 2 is the latest version of WSL, adding new features like a full Linux kernel and full system call compatibility. There used to be a handful of steps needed to install it, but we now only need to enter the following command into PowerShell or Command Prompt:

wsl --install

This command does the following:

• Enables the optional WSL and Virtual Machine Platform components
• Downloads and installs the latest Linux kernel
• Sets WSL 2 as the default
• Downloads and installs the Ubuntu Linux distribution (a reboot may be required)

Using the --install command defaults to Ubuntu and only works if WSL is not installed yet. If you would like to change your default Linux distribution, follow these docs.

User Config

Once the process of installing your Linux distribution with WSL is complete, open the distribution (Ubuntu by default) using the Start menu. You will be asked to create a User Name and Password for your Linux distribution. When you enter your new password, nothing will display in the terminal. Your keyboard is still working! It is just a security feature.

• This User Name and Password is specific to each separate Linux distribution that you install and has no bearing on your Windows user name.

• Once you create a User Name and Password, the account will be your default user for the distribution and automatically sign in on launch.

• This account will be considered the Linux administrator, with the ability to run sudo (Super User Do) administrative commands.

• Each Linux distribution running on WSL has its own Linux user accounts and passwords. You will have to configure a Linux user account every time you add a distribution, reinstall, or reset.

Updating Linux

It is recommended that you regularly update and upgrade your packages. In Ubuntu or Debian, we use the apt package manager:

sudo apt update && sudo apt upgrade

Windows does not automatically update or upgrade your Linux distribution(s). This is a task that most Linux users prefer to control themselves.

Mapping Your Linux Drive

When you open the Windows file explorer, it displays your devices and drives. We are going to add our Ubuntu virtual drive as a network location for easy access.

1. Open the \\wsl$\ location from file explorer:

2. Right-click on the Ubuntu folder, and select Map network drive:

3. Select the drive letter you would like to use, leave Reconnect at sign-in checked and Connect using different credentials unchecked, and then click finish (mine will look slightly different because it's already been done):

4. The result should look something like this:

If you wanted to access your Windows files from the Linux terminal, they are found in the /mnt/ directory, so your Windows user directory would be located at /mnt/c/Users/username.

With your Ubuntu drive mapped, you can easily drag/drop or copy/paste Windows files to the Linux file system by using the file explorer.

However, it is recommended to store your project files on the Linux file system. It will be much faster than accessing files from Windows and it can also be a little buggy.

Pin Your Code Directory

Another quick tip I have is to create a code directory inside of Ubuntu, and then pin it to the quick access menu found on the left side of the file explorer. This comes in handy when transferring files quickly between Windows and Linux.

1. Open File Explorer and click on the Ubuntu network drive we created
2. Select the home dir, and then your user directory
3. Right-click and create a new folder, name it code, or anything else you'd like
4. Drag that new folder to the left, underneath the star icon that says Quick access

Restarting WSL

If for some reason WSL stops working, you can restart it with these two commands from PowerShell/Command Prompt:

wsl.exe --shutdown
wsl.exe

If you return to your Linux shell everything should be normal.

👨‍💻 Windows Terminal

To launch a Linux terminal we currently need to use the Ubuntu icon from the Start menu or enter the wsl or bash commands into PowerShell/Command Prompt. Another option that will give us more features like tabs, split views, themes, transparency, and key bindings, is to use the Windows Terminal. There are also a few other terminals like Cmder, ConEmu, or Hyper, but in my experience, Windows Terminal works extremely well.

Installing Windows Terminal

Windows 11 comes with Windows Terminal by default, but If you are using Windows 10, Download and install Windows Terminal through the Microsoft Store.

Terminal Settings

A few quick things I recommend setting up are the default profile and your starting home directory. These settings make it so launching Windows Terminal will open directly into WSL inside our user's home directory.

Default Profile

Windows Terminal will open a PowerShell or Command Prompt shell when launched by default, here is how to switch it to WSL:

1. Select the ˅ icon from Windows Terminal and go to the Settings menu:

2. In the Startup section you will find the Default profile dropdown, select Ubuntu. Below it, select Windows Terminal as the Default terminal application:

Starting Directory

A default Ubuntu terminal will open to the root directory. To make finding your files a little quicker we can have it open into your home directory instead.

1. Under the Profiles section in the settings menu click on Ubuntu
2. At the General tab, you will find a Starting directory input
3. Enter the following replacing "username" with your Ubuntu user name: \\wsl$\Ubuntu\home\username
4. You can leave the Use parent process directory box unchecked
5. If it is still opening into your / directory, change the Command line setting located right above the Starting directory input box to the following: wsl.exe -d Ubuntu

There are many more settings to explore, and there is also a JSON file you can edit for more advanced customizations.

Check out this guide for some popular Windows Terminal themes and how to install them.

📝 Git Config

Git should come pre-installed on most, if not all of the WSL Linux distributions. To ensure you have the latest version, use the following command in an Ubuntu or Debian-based distro:

sudo apt install git

Name

To set up your Git config file, open a WSL command line and set your name with this command (replacing "Your Name" with your preferred username):

git config --global user.name "Your Name"

Email

Set your email with this command (replacing "[email protected]" with the email you prefer):

git config --global user.email "[email protected]"

Username

And finally, add your GitHub username to link it to git (case sensitive!):

git config --global user.username "GitHub username"

Make sure you are inputting user.username and not user.name otherwise, you will overwrite your name and you will not be correctly synced to your GitHub account.

You can double-check any of your settings by typing git config --global user.name and so on. To make any changes just type the necessary command again as in the examples above.

😺 GitHub Credentials

Creating your Personal Access Token

GitHub has removed the ability to use a conventional password when working in a remote repository. You are now required to create a personal access token instead.

Personal access tokens (PATs) are an alternative to using passwords for authentication to GitHub when using the GitHub API or the command line.

Follow these docs for step-by-step instructions on creating your personal token.

Git Credential Manager

Once you enter your token the first time, it can be stored via Git Credential Manager (GCM) so you won't have to authenticate yourself each time.

You can have Git installed in WSL and also in Windows at the same time. Git for Windows includes GCM and is the preferred way to install it.

You can also download the latest installer for Windows to install the GCM standalone version.

Storing Your Token

Once Git Credential Manager is installed you can set it up for use with WSL. Open your WSL terminal and enter this command:

git config --global credential.helper "/mnt/c/Program\ Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe"

Note:

If you ever receive the following error message:

/mnt/c/Program\ Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe store: 1:
/mnt/c/Program Files/Git/mingw64/libexec/git-core/git-credential-manager-core.exe: not found

Try using this command:

git config --global credential.helper store

💤 Zsh

Z shell works almost identically to the standard BASH shell found on default Linux installs. What makes it different is its support for plugins and themes, along with some extra features like spelling correction and recursive path expansion. It's time to throw BASH in the trash!

Installing Zsh

Zsh can be installed with one command:

sudo apt install zsh

After installing, type the zsh command. Zsh will ask you to choose some configurations. We will do this later on while installing oh-my-zsh, so choose option 0 to create the config file and prevent this message from showing again.

OhMyZsh

The most popular plugin framework by far is OhMyZsh. It comes preloaded with loads of plugins, themes, helpers, and more. It can help with productivity for sure, but more importantly, it just looks cool 😎.

cURL

First off, we need to make sure we have cURL installed. Short for "Client URL", it's a way to transfer data from the command line, and that's how we will download OhMyZsh.

sudo apt install curl

Installing OhMyZsh

Enter the following command into your terminal to install OhMyZsh:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

That's it! You should now see a .oh-my-zsh directory inside of your home directory. To change your plugins and themes you will need to edit your .zshrc file, also found in your home dir.

Here is a list of all the themes and plugins that come bundled with OhMyZsh.

More Plugins

There are countless plugins available, but these are the two I recommend most.

zsh-autosuggestions

Autosuggestions for zsh, It suggests commands as you type based on history and completions.

1. Clone this repository into $ZSH_CUSTOM/plugins (by default ~/.oh-my-zsh/custom/plugins)

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

2. Add the plugin to the list of plugins for Oh My Zsh to load (inside ~/.zshrc):

plugins=(git zsh-autosuggestions)

3. Start a new terminal session.

zsh-syntax-highlighting

This package provides syntax highlighting for the shell zsh. It enables the highlighting of commands whilst they are typed at a zsh prompt into an interactive terminal. This helps in reviewing commands before running them, particularly in catching syntax errors.

1. Clone this repository in oh-my-zsh's plugins directory:

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

2. Activate the plugin in ~/.zshrc:

plugins=(git zsh-autosuggestions zsh-syntax-highlighting)

3. Start a new terminal session.

A huge list of plugins can be found at the awesome zsh plugins repo.

📦 Node.js

Node.js is a JavaScript runtime environment that executes JavaScript code outside a web browser. It allows us to install packages, run local web servers, create APIs, and more.

NVM

You will likely need to switch between multiple versions of Node.js based on the needs of the different projects you're working on. Node Version Manager allows you to quickly install and use different versions of Node via the command line.

Installing NVM

1. Open your terminal and install NVM with curl or wget:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

To verify installation, enter: command -v nvm. This should return 'nvm', if you receive 'command not found' or no response at all, close your current terminal, reopen it, and try again.

2. List which versions of Node are currently installed (should be none at this point):

nvm ls

3. Install both the current and stable LTS versions of Node.js.

Install the current stable LTS release of Node.js (recommended for production applications):

nvm install --lts

Install the current release of Node.js (for testing the latest Node.js features and improvements, but more likely to have issues):

nvm install node

4. List what versions of Node are installed:

nvm ls

Now you should see the two versions that you just installed listed.

5. Verify that Node.js is installed and the current version:

node --version

Then verify that you have NPM installed as well:

npm --version

Changing Node Versions

Use the following commands to change the version of Node you would like to use for any given project:

Switch to the Current version:

nvm use node

Switch to the LTS version:

nvm use --lts

You can also use the specific number for any additional versions you've installed:

nvm use v8.2.1

To list all of the versions of Node.js available, use the command: nvm ls-remote.

NPM

Node Package Manager is the default package manager for Node.js. It is a command-line tool used to download or publish packages and manage the dependencies of a project. There is a searchable repository of all available NPM packages at https://www.npmjs.com/.

New Projects

When creating a new project that will utilize NPM, it must be initialized with the init command. First, make sure you are in the root directory of your project, and then use the following command:

npm init

package.json

npm init generates a package.json file and will prompt you for the metadata of your project. This includes things like the name, version, description, and license. You can think of it as the blueprint of your project as it will also contain the packages it depends on. The metadata can be changed at any time by editing the package.json file after the initialization.

If you would like to automatically populate the initialization with all the default values, you may add the --yes flag.

npm init --yes

Installing Modules

Modules are installed via the npm install or npm i command.

npm install react

The above command will install the React module as a dependency in package.json.

We can also install NPM packages globally on our system. This is useful for utilities like command line interfaces.

Yarn is another widely used node package manager, if we wanted to use it on all our node projects we would need the --global or -g flag.

npm install --global yarn

Dependencies

You can save a module as either a dependency or a developer dependency.

A dependency would be something that your project cannot function properly without.

The --save flag used to be needed to install modules as a dependency, but it is now done automatically with the install command.

npm install --save gray-matter

Is the same as:

npm install gray-matter

Developer Dependencies

A developer dependency would be the modules used to build the project, not run it. This would include things like linters and testing tools.

Developer dependencies are added with the --save-dev or -D flag. This adds the module to the devDependencies section of package.json

npm install --save-dev husky

Batch Installing

Apart from installing a single module, you can install all modules that are listed as dependencies and devDependencies:

npm install

This will install all modules listed in the package.json of your current directory.

If we only wanted to install the dependencies needed to run our project, the --production flag is used:

npm install --production

the --production flag will only install the modules from the dependencies section of package.json and ignore the devDependencies. The perk of this is notably reducing the size of the node_modules folder.

Uninstalling

Removing modules works in the same way as installing them. Flags will need to be used for any global or developer dependencies.

Dependencies:

npm uninstall react

Developer Dependencies:

npm uninstall --save-dev husky

Global Installs:

npm uninstall --global yarn

Versioning

Package versions are identified with major, minor, and patch releases. 8.1.1 would be major version 8, minor version 1, and patch version 1.

You can specify an exact version number by using the @ symbol.

npm install [email protected]

Two more symbols we can use are ^ and ~.

^ is the latest minor release. For example, npm install ^8.1.1 specification might install version 8.3.1 if that's the latest minor version.

~ is the latest patch release. In the same way as minor releases, npm install ~8.1.1 could install version 8.1.6 if that's the latest patch version available.

When using the npm install or npm i command, the latest minor version will be used.

package-lock.json

The exact package versions will be documented in a generated package-lock.json file.

The values found inside the dependencies and devDependencies objects of the package.json file include a range of acceptable versions of each package to install.

package-lock.json is generated by the npm install command and contains the exact versions of the dependencies used.

Scripts

package.json also contains a scripts property that can be defined to run command-line tools installed on the current project. This can include things like running tests, formatting your code, and launching a local server.

NPM scripts are run by using the run command. With the above configuration, you would use the following command to have prettier format your code:

npm run format

The keys in the scripts object are the command names and the values are the actual commands.

Check out the official NPM, NVM, and Node.js docs for more in-depth guides.

💻 Visual Studio Code

There are many amazing code editors available for free, but Visual Studio Code has become the de facto standard and my personal favorite.

Installing VS Code

VS Code is available on Windows, macOS, and Linux. You can download the latest Windows installer here. I recommend using the stable build.

Changing the Default Shell

The WSL2 shell can be chosen as the default VS Code terminal by pressing Ctrl + Shift + P and typing/choosing Terminal: Select Default Profile, then selecting zsh:

Remote Extension

Install the Remote - WSL extension on VS Code.

This allows you to use WSL as your integrated development environment and will handle compatibility and pathing for you. Learn more.

This extension will also allow you to launch VS Code right from your WSL terminal by using the code command.

If I were inside the root directory of my repository, I would use code . to launch the entire directory inside VS Code.

cd my-project
code .

More Extensions

The number of extensions available for VS Code can be overwhelming, here are some of the ones I use the most.

• Live Server - Launch a local development server with a live reload feature for static & dynamic pages.
• Live Share - Includes everything you need to start collaboratively editing and debugging in real-time.

Note:

You will need to install any VS Code extensions for your Remote - WSL. Extensions already installed locally on VS Code will not automatically be available. Learn more.

🍫 Chocolatey

Chocolatey is a command-line package manager like homebrew or APT, but for Windows.

Admin Shell

Before we start the installation process, I want to cover launching an administrative shell from Windows. There are a few ways to do this:

Option 1

Right-click on the Windows start menu and select Windows Terminal (Admin):

Once your terminal loads, click the ˅ icon and open a new PowerShell tab. It should say Administrator: Windows PowerShell in the new tab:

Option 2

If you have Windows Terminal on your taskbar, Shift + Right-Click on the icon select run as administrator, and then open a new PowerShell tab:

Option 3

Use the search bar from the Start menu and type in powershell. A link to Run as Administrator will display:

Option 4

Windows Terminal added a new feature where you can launch a PowerShell/Command Prompt profile in an Admin terminal automatically. In the Windows Terminal settings, scroll down to your desired profile and then toggle the Run this profile as Administrator switch. Now you can skip all the steps above, and the terminal will always launch as admin.

Installing Chocolatey

1. Open an administrative PowerShell terminal

2. Run the following command:

Get-ExecutionPolicy

3. If it returns Restricted, then run one of the following commands:

Set-ExecutionPolicy AllSigned

or

Set-ExecutionPolicy Bypass -Scope Process

With PowerShell, you must ensure Get-ExecutionPolicy is not Restricted. We suggest using Bypass to bypass the policy to get things installed or AllSigned for quite a bit more security.

4. Finally, run the following command:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

If you don't see any errors, you are ready to use Chocolatey! Type choco or choco -? now, or see Getting Started for usage instructions.

Basic Chocolatey Commands

We use the choco command to run Chocolatey. (Remember, you must use an administrative shell for it to work.)

Install a new package:

choco install filename

Remove a package:

choco uninstall filename

List all of the installed packages:

choco list

Update:

choco upgrade filename

or to update everything at once:

choco upgrade all

Windows Apps

Search for available apps on the Community Package Repository.

Here are a few of my favorite (free) apps for productivity and development on Windows:

• Wox - A full-featured launcher
• RunJs - JavaScript and TypeScript playground
• Responsively - A modified web browser that helps in responsive web development.
• Zeal - the Windows version of Dash
• Figma - A collaborative UI design tool
• draw.io - Flowchart maker and diagram software
• GitHub Desktop - A GUI for Git
• Postman - API tools
• Notion - Project management and note-taking software
• Obsidian - A note-taking app using markdown
• Microsoft PowerToys - A set of utilities for power users

You can download all these at once with the following command using Chocolatey in an admin shell:

choco install wox runjs responsively zeal figma drawio github-desktop postman notion powertoys obsidian -y

🪜 Chrome Extensions

These are all available as Firefox extensions as well.

• React Dev tools - Adds React debugging tools to the Chrome Developer Tools.
• ColorZilla - Advanced Eyedropper, Color Picker, Gradient Generator, and other colorful goodies
• Axe Accessibility - Accessibility Checker for Developers, Testers, and Designers in Chrome
• daily.dev - Get a feed of the hottest developer news personalized to you.
• Nimbus Capture - Screen Capture full Web page or any part.
• WhatFont - With this extension, you could inspect web fonts by just hovering on them.
• JSON Formatter - Makes JSON easy to read.

🇺🇸 VetsWhoCode Web App

Let's get the VWC App installed and running locally. It will be our first step toward making Open-Source contributions to the organization!

1. Clone the Repo

Download the repository from GitHub using git clone:

git clone https://github.com/Vets-Who-Code/vets-who-code-app.git

This may take a few minutes.

2. Change Directory

Change into the newly cloned directory:

cd vets-who-code-app

3. Install Node.js

Using nvm install will install the version of Node.js required by the VWC app:

nvm install

4. Install Dependencies

npm install is how we install React, Next, Bootstrap, and every other piece of tech that the app requires. This will also take a few minutes.

npm install

There will be a lot of warnings and other messages that display, but this is normal.

5. Environment Variables

Environment variables hold secret API keys and are needed to run the blog by connecting to the Contentful API.

We can create a default .env file that will use mock data for the blog when running it locally. Use the following command from the root of the vets-who-code-app directory:

cp .env.example .env

6. Run the App

Finally, we can launch the app on our local server:

npm run dev

You should be able to view the website locally at http://localhost:3000/].

CTRL + Left-click on the localhost link in your terminal to launch the app in your browser.

CTRL + C to close the dev server when you are finished.

🐍 Python

This section covers setting up a Python development environment in WSL. In the end, you will have a package manager, environment manager, some frameworks, extensions, and more.

The first step will be confirming that Python is already installed on your system:

python3 --version

A Python version number should be returned. If not, install it with:

sudo apt install python3

pip

pip is the package manager for Python, similar to npm for JavaScript. Install it using the following:

sudo apt install python3-pip

venv

venv allows you to create virtual environments for your Python projects, helping to prevent versioning conflicts.

sudo apt install python3-venv

Flask

Flask is a web development framework similar to Express for Node.js. It can be installed by using pip:

pip3 install flask

Django

Another popular web development framework is Django. Just as before, install it using pip:

pip3 install django

JupyterLab

JupyterLab is a web-based interactive development environment. It is a powerful tool used in data science, scientific computing, computational journalism, and machine learning. Install it using the following command:

pip3 install jupyterlab

JupyterLab can be launched using the jupyter-lab command.

Notebook

The next step is to install the Jupyter Notebook. It allows you to create and share documents from Jupyter.

pip3 install notebook

The notebook is run by using the jupyter notebook command.

Voilà

Voilà allows you to convert a Jupyter Notebook into an interactive dashboard that allows you to share your work with others.

pip3 install voila

Launch Voilà using the voila command.

Python VS Code Extensions

You will find a ton of Python extensions for VS Code, but here are a few of the more popular ones:

• Python - The official Python extension.
• Django - Syntax highlighting and snippets for Django.
• Python Indent - Correct Python indentation.
• Python Environment Manager - Manage all of your Python environments & packages.
• autoDocstring - Quickly generate docstrings for Python functions.
• Black Formatter - Code formatter for Python using Black
• AREPL - Automatically evaluates Python code in real-time as you type.
• Python Test Explorer - Run your Python tests in the Sidebar of Visual Studio Code.

PyCharm

Instead of using VS Code, another option is to use an IDE made specifically for Python development. JetBrains created one of the best and most widely used ones called PyCharm. There is a free community edition version that can be downloaded here.

💎 Ruby

In this section, we'll install Ruby using rbenv. Using rbenv will also allow you to install multiple Ruby environments on your machine, using different versions.

This guide continues installation with zsh as the default shell.

1. Install rbenv

sudo apt install rbenv

2. Follow the instructions to load rbenv in the shell:

rbenv init

The output will prompt you with instructions for loading rbenv. In your .zshrc, add the following line:

# Loading rbenv automatically
eval "$(rbenv init -)"

3. Restart your terminal to update the shell.

4. Before installing Ruby, you'll want to ensure your build environment contains the required tools and libraries:

sudo apt-get install autoconf bison patch build-essential rustc libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libgmp-dev libncurses5-dev libffi-dev libgdbm6 libgdbm-dev libdb-dev uuid-dev

5. Next, install ruby-build as a rbenv plugin, to make sure we don't have any problems with rbenv.

git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

6. Let's get Ruby installed:

Run this command to see which stable versions of Ruby are available:

rbenv install -l

Install the most recent stable version, which in this case is v3.1.2:

rbenv install --verbose 3.1.2

This can take a very long time. The --verbose flag will show the install progress, otherwise, it will look like it's frozen.

Ruby will be installed in your ~/.rbenv directory.

7. Set the global version, so that when you open a new terminal, it will use this version of Ruby.

rbenv global 3.1.2

8. Close your terminal and open a new session. Check your current version of Ruby:

ruby -v

You should see something like this:

ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux]

Rails

Now that Ruby is installed, you can install Rails. Ruby has its built-in package manager, called RubyGems. This is what you'll use to install Rails.

Enter the following to install Rails v7.0.4: The --no-document flag speeds up the installation by skipping the gem documentation files.

gem install rails -v 7.0.4 --no-document

1. Next you'll need to install a shim to associate the rails command with rbenv:

rbenv rehash

This command should run automatically after gems are installed

2. Close your terminal and open a new session. Verify Rails was successfully installed:

rails -v

You should see this in your terminal:

Rails 7.0.4

Docker

This section covers setting docker desktop for Windows. In the end, you will have a docker-daemon, docker-cli, docker-compose, and more.

Docker provides the ability to package and run an application in a loosely isolated environment called a container.

• Docker Documentation

Docker Installation

• Docker uses virtualization to run containers so there are two options to run Docker either via WSL (recommended) or Hyper-V. If you have wsl enabled docker currently by default runs on wsl.

• What should you use? Difference Between Hyper-V and Wsl

• If you don't have wsl2 you need to enable Hyper-V Guide

Again there are two ways you can install docker-desktop on your Windows machine:

Option 1

Using Chocolatey CLI package manager which we installed earlier.

For installation we will need a shell with administrative privileges, we covered how to run Powershell as an administrator while installing Chocolatey. Using any of the options open up a PowerShell.

choco install docker-desktop

Option 2

Direct install via executable available on docker.com

Step 1 - Download the executable for docker-desktop.

Step 2 - Install the executable, and choose the appropriate virtualization environment while installing if the option shows up.

Step 3 - Done with installation. Sign in with the docker account or skip for the time being.

Test Docker CLI

Make sure you at least launch docker-desktop once, and let it run in the background.

docker -v

docker

docker info

You have successfully installed docker-desktop and all other necessary tools docker-cli, docker-compose, and more.

Docker Basics

Docker CLI

Let's test some of the docker functionalities using the CLI.

List all the running containers:

docker ps

List all the available images locally:

docker images ls -a

Run a container:

• p tag for specifying the port
• d tag for detaching the shell

docker run -p 8080:80 httpd

The above command will fetch a public image of httpd which is an Apache HTTP server. It then runs it as a Docker container exposing port 80, and making it available to port 8080 of our local machine. You can visit localhost and view the content served by this container.

Now if you run the ps command again it will list out this container.

Stop the running docker container:

docker stop [container-id]
