Docker Desktop on Windows 11: Install, Use WSL 2 and Run Your First Container

Docker Desktop gives Windows 11 users a practical way to build and run containerized applications without maintaining a separate Linux server for everyday development and testing. Docker currently recommends its per-user installation with the WSL 2 backend for most Windows users.

This PCFix411 guide covers the normal Windows 11 workflow: verify virtualization and WSL, install Docker Desktop from an official source, run a test container, understand images, ports and persistent storage, and troubleshoot the most common setup failures.

Quick Answer: What You Need

• A supported 64-bit Windows 11 installation
• Hardware virtualization enabled in BIOS/UEFI
• WSL 2 enabled and current
• At least 8 GB RAM under Docker’s current Windows requirements
• Adequate SSD space for images, containers and project files

Docker’s current Windows installation instructions are at Install Docker Desktop on Windows.

1. What Is a Container?

A container packages an application with the libraries, runtime and configuration it needs so it can run consistently across compatible systems. Unlike a traditional virtual machine, a container normally does not include an entire guest operating system.

For Windows developers using Linux containers, Docker Desktop commonly runs the container engine in a lightweight Linux environment through WSL 2.

2. Check Windows and WSL First

Press Windows + R, type winver, and press Enter to see your Windows build. Docker supports current serviced Windows releases, so check its requirements if the PC is running an older build.

Then open Windows Terminal or PowerShell and run wsl --version. Docker currently lists WSL 2.1.5 or later for its WSL 2 backend. Use wsl --update when necessary. If WSL is not installed, Microsoft supports wsl --install.

PCFix411’s WSL 2 Guide covers the Windows Linux environment in more detail.

3. Verify Hardware Virtualization

Open Task Manager and go to Performance > CPU. Look for Virtualization: Enabled. If it is disabled, you may need to enable Intel virtualization technology or AMD virtualization/SVM in BIOS/UEFI. Do not change unrelated firmware settings.

4. Install Docker Desktop

Download Docker Desktop from Docker’s official site or its Microsoft Store listing. Docker currently recommends per-user installation for most users, and WSL 2 is the default backend for the majority of Linux-container workflows.

5. Understand Docker Desktop Licensing

Docker Desktop is free for personal use, education, non-commercial open-source work and qualifying small businesses. Docker’s current terms say commercial use in larger organizations—more than 250 employees or more than $10 million in annual revenue—requires a paid subscription. Government use also has separate paid requirements. Business users should verify the current Docker agreement before deployment.

6. Verify the Engine and Run Hello World

After Docker Desktop starts, run docker version. You should see client and server information. Then run docker run hello-world. Docker downloads the small test image, creates a container and prints a confirmation message. If this works, the basic engine and image-pull path are functioning.

7. Image vs Container

An image is the packaged template. A container is a running or stopped instance created from that image. One image can create many containers. Removing a container does not automatically remove its image.

8. Run a Simple Web Server

To launch Nginx and expose it on local port 8080, run docker run --name pcfix-nginx -d -p 8080:80 nginx, then open http://localhost:8080 in your browser. The mapping means Windows port 8080 forwards to port 80 inside the container.

Use docker ps to list running containers and docker ps -a to include stopped containers.

9. Persistent Storage Matters

Containers are designed to be replaceable. Important application data should not live only inside a disposable container filesystem. Docker volumes and bind mounts let data persist outside the life of one container.

Create a named volume with docker volume create pcfix-data. Always read the image documentation so you mount the correct data directory.

10. Docker Compose

Docker Compose describes a multi-container application in a YAML file. Instead of typing long commands for a web server, database and supporting services, define the stack and start it with docker compose up -d. Stop and remove the stack with docker compose down.

11. Security Basics

Containers are not automatic security boundaries. Risks include vulnerable images, exposed ports, embedded passwords, privileged containers and access to the Docker daemon. Use trusted official or verified images and never hard-code API keys, passwords or private tokens into a Dockerfile or public image.

Docker warns that access to the Docker daemon socket can grant very high privileges on the host, so only trusted users should receive that access.

12. RAM and SSD Space

Containers can consume memory and storage quickly. Docker’s current Windows requirements list at least 8 GB RAM, but a workstation running an IDE, browser and several services benefits from more.

For Windows memory planning, see How Much RAM Does Windows 11 Really Need in 2026?.

Old images, build cache and stopped containers can also consume many gigabytes. Use docker system df to inspect storage before deleting anything. Broad prune commands can permanently remove images, containers or volumes, so back up important project data first. PCFix411’s Windows 11 Backup Guide covers a safer backup foundation.

13. Docker Desktop Will Not Start

1. Restart Windows.
2. Verify virtualization is enabled.
3. Run wsl --version.
4. Run wsl --update if needed.
5. Confirm Windows is on a Docker-supported build.
6. Read Docker Desktop’s actual error before reinstalling.

If WSL itself is broken, fix WSL before repeatedly reinstalling Docker Desktop.

14. Port Already in Use or Container Exits

If Docker cannot bind a port, another application or container may already be listening there. Change the host-side port or identify the process using it. For example, use docker run -d -p 8081:80 nginx if 8080 is occupied.

If a container exits immediately, run docker logs CONTAINER_NAME. Missing environment variables, configuration errors and invalid commands are common causes.

15. When Docker Desktop Is Overkill

If you only need one ordinary Windows application, install the Windows application. If you need a completely isolated operating system, use a virtual machine. If you are deploying a production service, use a production-appropriate server or container platform rather than treating a developer desktop tool as your permanent production server.

Good PCFix411 Use Cases

• testing WordPress or web applications locally
• learning Linux services without a separate server
• running repeatable development environments
• testing databases and APIs
• reproducing client/server stacks
• learning containers before moving workloads to a VPS or cloud host

Docker Desktop Setup Checklist

1. Confirm a supported Windows build.
2. Confirm adequate RAM and SSD space.
3. Enable virtualization.
4. Install or update WSL 2.
5. Install Docker Desktop from an official source.
6. Use WSL 2 for the normal Linux-container workflow.
7. Run docker version.
8. Run docker run hello-world.
9. Test a simple port-mapped web container.
10. Learn volumes before putting important data in containers.

Bottom Line

Docker Desktop is one of the easiest ways to learn and use containers on Windows 11. Start with the WSL 2 backend, verify virtualization and WSL before troubleshooting Docker itself, keep important data in deliberate persistent storage, and treat images and daemon access as security-sensitive. Once the basic tests work, move to Docker Compose and project-specific stacks instead of building a complicated environment all at once.
