FAQ

Why is Docker not starting on my Windows machine?

Check that virtualization is enabled in your BIOS and that WSL 2 is properly installed. Also, make sure Docker Desktop is running with administrative privileges.

Can I use Docker without WSL 2?

Yes, but WSL 2 is recommended for better performance and compatibility with Linux containers. Docker can also use Hyper-V as an alternative backend.

How do I switch between Linux and Windows containers?

Right-click the Docker icon in your system tray and select "Switch to Windows containers" or "Switch to Linux containers," depending on your current mode.

Is Docker Desktop free?

Docker Desktop is free for personal use, education, and small businesses. Larger organizations may require a paid subscription. Check Docker’s licensing page for details.

Final Thoughts

Docker on Windows opens up a world of possibilities for developers, testers, and tech enthusiasts. Whether you're building microservices or just want a cleaner dev environment, Docker is a must-have tool.
