Container with WSL

• Install Docker with WSL

With WSL 2, we can setup Docket Desktop and enable WSL 2 based engine.

First you install WSL 2. Then you download Docker Desktop from https://www.docker.com/products/docker-desktop and install it. After that, you have to log out and log in again to run Docker Desktop. Then, right click on the Docker icon on the system tray and select Setting. Enable the option Use the WSL 2 based engine to configure Docker run under WSL 2 rather than a Virtual Machine.

 For the tab Resources, we can configure which Linux distro to access Docker from.

• Setup Kubernetes

In the Docker Desktop settings, we can enable the Kubernetes option to setup the Kubernetes cluster.

WSL Tips

• Access Linux files from Windows

            After installing WSL and Linux distro, if you type \\WSL$ on the address bar of Windows Explorer, you can see all Linux distro that are installed on your machine. And from that, you can access to the file system of the Linux distro from Windows.

 

• Access Windows files from Linux

            WSL automatically mount the Windows drive as /mnt. To access C drive, we can use /mnt/c

• Export/Import a Distro

            If we work with multiple projects and each project need different set of tools, then we can clone the base distro by export and import with a new name.

            Export: wsl --export ...

            Import: wsl --import ...

• Create a custom Distro from a docker container
• Firstly, we pull a container from Docker hub 
• Second step is to start the container with docker run  command.
• Third step: we add user for WSL

                    useradd -m YOURUSERNAME

                    passwd YOURUSERNAME

• Then we add /etc/wsl.conf file to let WSL know the user we created

                    echo -e "[user] \ndefault=YOURUSERNAME" > /etc/wsl.conf

• If we want to add more configuration, we can add at this step.
• After finish adding the configurations, we can export the Docker container to the Tar file using docker export command.
• Then we use wsl --import  command to import the Tar file. And now we have a new Distro to run.
• Create a custom Distro from a docker container using Docker file

            For the manual steps above, we can build a Docker file to create a custom Distro.

How to run Visual Studio Code with WSL

Install Visual Studio Code on Windows.

Then make sure we install Visual Studio Code extension Remote - WSL.

Optional step: Windows has a new terminal tool that is good to communicate with Linux running in WSL. Its main features include multiple tabs, panes, Unicode and UTF-8 character support, a GPU accelerated text rendering engine, and custom themes, styles, and configurations. You can install it here or github.

From the WSL command line tool, in the source code folder, we can start Visual Studio Code using command Code .

And from Windows, we can edit and compile source code in WSL.

Windows Subsystem for Linux

Windows Subsystem for Linux is a great tool that let developers try Linux tools, applications directly in Windows. The Linux kernel and Windows kernel can now share system resources, such as memory and CPU. 

I am trying some open sources that cannot run on Windows. They are working well with WSL2.

• Rocket.Chat: I compiled and run successfully.
• Apache Airflow: Run successfully.

Beside that, from Windows, developers can use tools to code or interact with the applications, source code in WSL system. Some are:

• Windows Terminal supports console to Linux system. 
• Visual Studio Code supports development with source code in Linux system.
