Introduction: A New Era for Linux Containers on Windows
For years, developers working with Linux containers on Windows have relied heavily on Docker Desktop as the bridge between Microsoft’s operating system and the Linux ecosystem. While Docker transformed container development into an industry standard, it also introduced licensing considerations, additional background services, and another dependency developers had to manage.
Microsoft is now changing that equation.
With the introduction of WSL Containers in Windows 11, developers can build, run, and manage Linux containers directly through the Windows Subsystem for Linux (WSL) without requiring Docker Desktop in the background. Although still available as a public preview, this first-party solution represents Microsoft’s strongest commitment yet to making Windows a native-class Linux development platform.
This release is far more than another WSL update. It reflects Microsoft’s long-term vision of integrating Linux workloads directly into Windows while simplifying enterprise deployment, application development, AI workloads, and container management.
Windows 11 Gains Native Linux Container Support
Microsoft’s latest WSL preview introduces WSL Containers, allowing Linux containers to operate directly inside Windows using Microsoft’s own tooling instead of relying on third-party desktop runtimes.
It is important not to confuse this feature with the previously rumored “WSL 3.” Microsoft officially dismissed those rumors earlier, making it clear that WSL Containers are an enhancement to the current WSL ecosystem rather than an entirely new generation.
After testing the preview build with real-world container workloads, the experience proves surprisingly mature despite remaining under active development.
Summary
WSL Containers introduce a built-in Linux container platform integrated directly into Windows 11. Instead of installing Docker Desktop, developers receive Microsoft’s own command-line utility, wslc, alongside a dedicated container API for Windows applications.
Underneath, Microsoft still relies on the proven open-source Moby container engine—the same technology powering Docker itself—but wraps it inside Windows-native management and Hyper-V isolation.
Developers can already build images, expose web services, utilize GPU acceleration, and integrate containers into development environments such as Visual Studio Code. Enterprise administrators also receive centralized policy management, security visibility, and registry restrictions.
However, some familiar Docker capabilities—including Docker Compose, graphical dashboards, and Docker’s plugin ecosystem—remain unavailable for now. As a result, WSL Containers currently complement Docker Desktop rather than replace it completely.
Nevertheless,
Understanding What WSL Containers Actually Are
At its core, WSL Containers extend the Windows Subsystem for Linux into a complete Linux container runtime.
The platform consists of two major components.
The first is wslc.exe,
wslc build
wslc run
wslc ps
wslc image ls
mirror Docker almost identically.
Microsoft even provides an alias named container.exe, making migration even easier.
The second component is a dedicated WSL Container API, distributed through NuGet for C, C++, and C developers. Instead of launching Docker externally, Windows applications can silently create Linux containers, execute Linux-specific code, and terminate those containers automatically.
This architecture allows Windows software to leverage Linux functionality without exposing any complexity to the end user.
Microsoft’s Enterprise-Focused Architecture
Unlike Docker Desktop, which runs all containers inside one shared virtual machine, WSL Containers isolate every application inside its own Hyper-V-backed virtual machine.
That design consumes slightly more resources, but dramatically increases security.
Each application becomes isolated from every other application, creating stronger security boundaries that enterprise customers have repeatedly requested.
Although each container receives its own isolated environment, Microsoft still relies on the familiar WSL service underneath, ensuring compatibility with existing Linux distributions.
Rather than reinventing container technology, Microsoft is simply integrating it much deeper into Windows.
Installing WSL Containers
Since the feature currently exists only in
Administrators simply need to execute:
wsl --update --pre-release
Then restart WSL:
wsl --shutdown
After reopening Windows Terminal, installation can be confirmed with:
wslc --version
If everything succeeds, version 2.9.3.0 confirms that WSL Containers are installed correctly.
Most installations complete within only a few minutes.
Building and Running Linux Containers Without Docker
Once installed, WSL Containers feel remarkably familiar.
Developers can immediately pull Linux images:
wslc run -it debian:latest
Inside the container, Linux behaves exactly as expected.
Creating custom images also follows the Docker workflow.
Using a standard Containerfile, developers can package Python applications, install Linux utilities, expose network ports, and launch services with minimal adjustments.
Building images requires only:
wslc build -t my-linux-inspector .
Running those containers works equally well:
wslc run -d -p 5000:5000 --name inspector my-linux-inspector
A Flask application running inside Linux immediately becomes available through:
http://127.0.0.1:5000
No Docker Desktop.
No additional networking setup.
No third-party software.
GPU Acceleration Makes AI Workloads Practical
One of the most exciting capabilities involves GPU passthrough.
Machine learning developers often require direct CUDA access inside Linux containers, and Microsoft has preserved Docker’s familiar syntax.
wslc run --rm --gpus all pytorch/pytorch:2.5.1-cuda12.4-cudnn9-runtime \npython -c "import torch; print(torch.cuda.is_available())"
The container receives direct GPU access, allowing AI frameworks like PyTorch to fully utilize hardware acceleration instead of falling back to CPU execution.
For developers building inference engines or training models locally, this feature alone could justify trying WSL Containers.
Enterprise Security and Centralized Management
Microsoft clearly designed WSL Containers with enterprise deployment in mind.
Organizations can already manage container usage through Group Policy and ADMX templates.
Administrators may:
Enable or disable WSL entirely.
Allow only approved Linux containers.
Restrict container image registries.
Prevent downloads from unauthorized public registries.
Integrate security monitoring with Microsoft Defender for Endpoint.
These controls significantly simplify container governance across large Windows deployments.
Microsoft also expects full Microsoft Intune integration shortly after the preview period.
Visual Studio Code Support Arrives Immediately
Developers using Visual Studio Code receive native integration through the Dev Containers extension.
Beginning with version 0.462.0-pre-release, switching to WSL Containers only requires replacing the Docker executable path with:
wslc
Existing development environments continue working with minimal reconfiguration.
Current Limitations Developers Should Know
Despite the impressive progress, WSL Containers remain incomplete.
The largest missing feature is Docker Compose.
Modern applications often consist of multiple services running together:
Databases
Redis
APIs
Background workers
Reverse proxies
Today, every container must be started manually.
Graphical dashboards are also absent.
There is no equivalent to Docker
Networking improvements such as Consomme, along with the new virtiofs filesystem, are currently exclusive to WSL Containers but may eventually reach regular WSL distributions.
Should Developers Replace Docker Desktop Today?
For lightweight projects involving a single Linux service or database, WSL Containers already provide a compelling alternative.
Developers can eliminate Docker Desktop entirely while maintaining nearly identical command syntax.
However, professionals managing large Compose projects, complex orchestration workflows, or extensive Docker plugins will still find Docker Desktop considerably more mature.
Fortunately, Microsoft designed both solutions to coexist peacefully, allowing developers to experiment with WSL Containers without disrupting existing workflows.
General availability is currently expected during Fall 2026, giving Microsoft time to close the remaining feature gaps.
Deep Analysis: Linux Commands and Technical Workflow
WSL Containers represent a significant architectural evolution because Microsoft is no longer treating Linux as a secondary platform. Instead, Linux becomes an integrated runtime within Windows itself.
From a systems perspective, Microsoft is leveraging proven open-source technologies rather than creating incompatible alternatives. The decision to build upon the Moby engine ensures long-term compatibility with existing container images while reducing migration friction for developers.
Linux commands remain familiar throughout the workflow:
wsl --update --pre-release
wsl --shutdown
wslc --version
wslc --help
wslc run -it debian:latest
uname -a
wslc ps -a
wslc attach <container-name>
wslc build -t my-linux-inspector .
wslc image ls
wslc run -d -p 5000:5000 --name inspector my-linux-inspector
curl http://127.0.0.1:5000
wslc logs inspector
wslc stop inspector
wslc rm inspector
wslc images
wslc pull ubuntu:latest
wslc exec inspector bash
wslc run --rm --gpus all pytorch/pytorch:2.5.1-cuda12.4-cudnn9-runtime
Technically,
Perhaps the most strategic aspect is Microsoft’s decision to mirror Docker’s command syntax. This dramatically lowers the learning curve and positions WSL Containers as a nearly drop-in replacement for many development scenarios.
If Microsoft eventually delivers Docker Compose compatibility, graphical management tools, and richer orchestration features, WSL Containers could become the default Linux development environment for millions of Windows users.
What Undercode Say:
Microsoft’s WSL Containers represent one of the most strategic Windows developer features released in years.
Rather than competing directly against Docker, Microsoft is gradually integrating Docker-like capabilities into Windows itself.
This is a smart long-term strategy.
Developers dislike changing workflows.
Microsoft understands that.
By preserving
The decision to continue using the Moby engine is equally important.
Compatibility matters more than reinvention.
Enterprise customers will likely appreciate Hyper-V isolation.
Security has become one of the largest concerns in container deployments.
Separate virtual machines significantly reduce attack surfaces.
Performance trade-offs appear reasonable.
Most local development workloads rarely push virtualization limits.
GPU passthrough is another major advantage.
AI development increasingly depends on hardware acceleration.
Native CUDA access without Docker Desktop lowers the entry barrier.
Visual Studio Code support further strengthens adoption.
Developers can continue using existing workflows.
Minimal configuration changes reduce friction.
However, Docker Compose remains the elephant in the room.
Modern microservice applications rarely consist of a single container.
Without Compose, many professional teams cannot migrate entirely.
Docker’s ecosystem also remains unmatched.
Years of extensions, dashboards, integrations, and community tooling cannot be replaced overnight.
Microsoft appears fully aware of this.
Rather than forcing migration, it offers an alternative.
That strategy usually succeeds.
The integration with Defender and enterprise policies demonstrates Microsoft’s commercial priorities.
Corporate customers often value governance more than convenience.
The preview already feels surprisingly polished.
If Compose support arrives before general availability, adoption could accelerate rapidly.
Windows is slowly becoming one of the strongest Linux development environments available.
That statement would have sounded impossible just a decade ago.
Today, it is increasingly becoming reality.
Prediction
(+1) Microsoft successfully introduces Docker Compose compatibility before the final release, making WSL Containers the preferred development environment for a large portion of Windows developers. 🚀
(-1) If advanced orchestration, plugins, and graphical management tools remain absent, Docker Desktop will continue dominating professional enterprise workflows despite Microsoft’s growing native ecosystem. 📉
