No more dual boot or VM! Let's build a Linux environment with WSL2 & Windows Terminal [WSL2]

WSL2 was announced at MSBuild in 2019
- https://www.youtube.com/watch?v=GtVcDo1G8r8
This is a video of the announcement in KeyNote of de: code. WSL2 will be introduced around 54:40
By installing WSL2, Windows will include the Linux kernel, so you will not need a VM or dual boot to build a Linux environment.
KeyNote for de: code 2019 will run npm isntall insanely fast! I was also doing a demo

Install WSL2 (Ubuntu)

I referred to this MS official document: https://docs.microsoft.com/ja-jp/windows/wsl/wsl2-install

Updated Windows version to Preview version

First of all, to use WSL2. You need to use the Preview version of Windows
(Because it is a preview version, we recommend that you keep a backup just in case)
Join Windows Insider and install the Preview version of Windows
To check the version, run the ver command at the command prompt and make sure the version of Windows is 10.0.18917 or higher.

C:\Users\user1>ver
Microsoft Windows [Version 10.0.19041.21]

Install a Linux distribution

First, make sure you have a Linux distribution installed
If Linux is not installed, the following message will appear

PS C:\Users\user1> wsl -l
The distribution is not installed on the Windows subsystem for Linux.
Distributions can be installed by visiting the Microsoft Store:
https://aka.ms/wslstore

Visit https://aka.ms/wslstore to open the Microsoft Store and see the distros you can install.
This time I will install Ubuntu
Booting Ubuntu from the store will start the subsystem installation

Installing, this may take a few minutes...
Please create a default UNIX user account. The username does not need to match your Windows username.
For more information visit: https://aka.ms/wslusers
Enter new UNIX username: myuser
Enter new UNIX password:

Of course you can also type Linux commands. You can now install it!

myuser@DESKTOP-KH1ORKF:~$ ls
myuser@DESKTOP-KH1ORKF:~$ cd ..
myuser@DESKTOP-KH1ORKF:/home$

Enable WSL

Restart your PC after entering the two commands below to enable WSL

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

After restarting, enter the wsl -l command to display the distribution you just installed.

PS C:\Users\user1> wsl -l
Windows subsystem distribution for Linux:
Ubuntu (default)

Finally, set up the Ubuntu distribution for WSL2

PS C:\Users\user1> wsl --set-version Ubuntu 2
Converting. This process can take a few minutes...
For the main differences from WSL 2, https://aka.ms/See wsl2
The conversion is complete.

You can now use WSL2!

Install Windows Terminal

Linux environment construction is completed by installing only WSL2, but since it is a big deal, I will also try using Windows Terminal announced at the same time as WSL2
Windows Terminal is simply an "evolved version of the command prompt"
Not only command prompt and PowerShell, but also Linux terminal can be executed with this one Windows Terminal by installing WSL.
Windows Terminal introduction video: https://www.youtube.com/watch?v=8gw0rXPMMPE
Windows Terminal can install the Preview version from the Microsoft Store
When you start Windows Terminal, you can select the Ubuntu terminal you installed earlier.
