Spinning up an isolated, empty container sandbox is a great way to verify your terminal environment works. But in the real world, you need your containerized applications to actually do something—like serving a web app you are actively developing inside your favorite Linux distribution.

Because native WSL Containers (wslc) run inside their own lightweight utility VM boundaries, they are completely isolated from your other WSL environments (like Ubuntu or Red Hat) by default. To do real work without resorting to bloated third-party tools or duplicating files, we need to explicitly bridge network traffic and mount cross-distro storage. Here is how to map local project folders and expose network ports using pure command-line tools.

1. Understand the Cross-Distro Storage Bridge

Instead of copying code files out of your development environment and onto the Windows host filesystem, we can leverage the Windows MUP (Multiple UNC Provider) pathing system.

Windows sees active WSL distributions as local network locations accessible via \\wsl.localhost\. The native wslc engine can tap directly into this path, allowing a container to read and write files live inside another running distribution.

  1. Identify the exact name of the distribution where your project files live by running this from PowerShell:
    wsl --list --running
  2. Note the internal directory structure. For example, if your website lives inside a Red Hat distribution at /home/clintd/open-linux-website, the Windows host reads this exact path as:
    \\wsl.localhost\REDHAT-10\home\<user>\<directory>

This approach prevents massive file duplication, saving your hard drive from unnecessary wear and keeping your system completely clutter-free.

2. Deploy a Detached, Linked Web Server

Let’s put this into practice by spinning up a lightweight Nginx web server container. We will configure it to run silently in the background, serve files directly out of your development distribution, and expose a port so you can view the live site from your host web browser.

  1. Execute the full deployment command from your Windows command line or PowerShell terminal:
    wslc run -d -p 8080:80 --name my-nginx -v \\wsl.localhost\REDHAT-10\home\bob\my-website:/usr/share/nginx/html nginx
  2. Break down exactly why this command functions the way it does:
    • -d: Runs the container in “detached” mode. This pushes the runtime into the background and hands your terminal prompt back to you instantly.
    • -p 8080:80: Maps port 8080 on your host machine to port 80 inside the container.
    • -v \\wsl.localhost\...: Binds your development folder directly into Nginx’s default public HTML directory. Any change you save inside your Linux distro updates the website instantly in real time.
  3. Open your preferred privacy-respecting browser on the Windows host and navigate to http://localhost:8080 to verify the container is serving your project.

Pro-Tip: If you execute this command inside PowerShell, the raw backslashes in the \\wsl.localhost path can occasionally trip up the shell’s argument parser. Wrap the entire local path in single quotes ('\\wsl.localhost\REDHAT-10\...') to force PowerShell to treat the string literally and avoid path resolution errors.

3. Clean Up Your Workspace

When you are finished testing your code changes, you don’t want background daemons lingering and wasting CPU cycles. Because we ran the container in detached mode, we must explicitly halt and remove the runtime instance.

  1. Stop the background container process gracefully:
    wslc stop my-nginx
    Why this happens: This sends a termination signal to the Nginx process inside the utility VM, shutting it down safely without corrupting any open files in your linked distribution.
  2. Remove the container configuration to clean up your local cache:
    wslc rm my-nginx

By mastering cross-distro volumes and port mapping, you keep your system architecture completely modular. Your code stays safe in your primary Linux environment, your host OS stays free of bloat, and you retain total command-line control.
