====== Install Docker in WSL and use it on Windows ======

First, install WSL for windows : search from start menu for "//Turn Windows features on or off//" and select "**Windows Subsystem for linux**" \\ 

Next, install ubuntu:

<code bash>
wsl --set-default-version 2
wsl --install -d Ubuntu
</code>

Go in Ubuntu:
<code bash>
wsl -l -v
wsl -d Ubuntu
</code>

From there, install docker:
<code bash>
sudo apt-get update

sudo apt-get -y install apt-transport-https ca-certificates curl gnupg lsb-release

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg 

echo "deb [arch=$(dpkg --print-architecture) 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

sudo apt-get update
sudo apt-get -y install docker-ce docker-ce-cli containerd.io
sudo groupadd docker
sudo usermod -aG docker $USER
</code>

To start:
<code bash>
sudo service docker start
</code>

To automatically start at startup, add at the end of the file:
<code bash>
vi ~/.bashrc
if (! pgrep dockerd > /dev/null); then
    sudo service docker start
fi
</code>

And also in order to not require a password for the above command, add to the end:
<code>
sudo visudo
your-username ALL=(ALL) NOPASSWD: /usr/sbin/service docker start
</code>

Now you can run wsl docker commands. \\ 
To get rid of the wsl prefix save this as docker.bat in C:\Windows:
<code batch docker.bat>
@echo off
wsl docker %*
</code>

==== Automatically Start Ubuntu WSL at Startup without Showing CMD ====

Open **Notepad** and create a batch script with the following command:    

<code batch start_wsl.bat>
@echo off
wsl -d Ubuntu
</code>

Save the file as `start_wsl.bat` in the `C:\Windows` directory.
    
Create a shortcut to the batch file.
Right-click on the `start_wsl.bat` file, and choose **Create Shortcut**. \\ 
Next, set the shortcut to run minimized:
    - Right-click the newly created shortcut, and select **Properties**.
    - In the **Shortcut** tab, set **Run** to **Minimized**.
    - Click **OK** to save the settings.

Then, move the shortcut to the Windows **Startup** folder:
    - Press *Win + R*, and type `shell:startup`, then hit **Enter**. This opens the **Startup** folder.
    - Move the shortcut you created into this folder.

Now, WSL (Ubuntu) will automatically start whenever Windows boots up, without showing the CMD window.
