Windows Subsystem for Linux (WSL) 2 introduces a significant architectural change as it is a full Linux kernel built by Microsoft, allowing Linux containers to run natively without emulation. With WSL2, Docker can run in it’s full flow in Windows and you can use Docker images built for Linux. The public release of WSL 2 should arrive by late May. Fortunately, most people running Docker containers in Windows are doing so for for development, rather than production purposes. Also bear in mind that any risk of container breakout, where the container gets full access to the host machine, is mitigated by the fact that the Docker daemon in Docker for Windows is running inside a virtual machine. Run Windows 10 In Docker On Linux. To publish all ports, use the -P flag. For example, the following commandstarts a container (in detached mode) and the -P flag publishes all exposed ports of thecontainer to random ports on the host. See the run command for more details onpublish options used with docker run. Run Docker Linux On Windows Server.
This topic describes how to run your first Windows container, after setting up your environment as described in Get started: Prep Windows for containers. To run a container, you first install a base image, which provides a foundational layer of operating system services to your container. Then you create and run a container image, which is based upon the base image. For details, read on.
Install a container base image
All containers are created from container images. Microsoft offers several starter images, called base images, to choose from (for more details, see Container base images). This procedures pulls (downloads and installs) the lightweight Nano Server base image.
Open a command prompt window (such as the built-in command prompt, PowerShell, or Windows Terminal), and then run the following command to download and install the base image:
If you see an error message that says
no matching manifest for unknown in the manifest list entries, make sure Docker isn't configured to run Linux containers.
After the image is finished downloading—read the EULA while you wait—verify its existence on your system by querying your local docker image repository. Running the command
docker imagesreturns a list of installed images.
Here's an example of the output showing the Nano Server image.
Run a Windows container
For this simple example, a ‘Hello World’ container image will be created and deployed. For the best experience, run these commands in an elevated command prompt window (but don't use the Windows PowerShell ISE—it doesn't work for interactive sessions with containers, as the containers appear to hang).
Start a container with an interactive session from the
nanoserverimage by entering the following command in your command prompt window:
After the container is started, the command prompt window changes context to the container. Inside the container, we'll create a simple ‘Hello World’ text file and then exit the container by entering the following commands:
Get the container ID for the container you just exited by running the docker ps command:
Create a new ‘HelloWorld’ image that includes the changes in the first container you ran. To do so, run the docker commit command, replacing
<containerid>with the ID of your container:
When completed, you now have a custom image that contains the hello world script. This can be seen with the docker images command.
Here's an example of the output:
Finally, run the new container by using the docker run command with the
--rmparameter that automatically removes the container once the command line (cmd.exe) stops.
The result is that Docker created a container from the 'HelloWorld' image, Docker started an instance of cmd.exe in the container, and the cmd.exe read our file and output the contents to the shell. As the final step, Docker stopped and removed the container.
Run a Windows container using Windows Admin Center
You can use Windows Admin Center to run your containers locally. Specifically, you use the the Containers extension of your Windows Admin Center instance to run the containers. First, open the container host you want to manage, and in the Tools pane, select the Containers extension. Then, select the Images tab inside the Container extension under Container Host.
If your host doesn't have a base container image, select the Pull option to open the Pull Container Image settings:
In the Pull Container Image settings, provide the image URL and the tag. If you aren't certain which image to pull, Windows Admin Center provides a list of common images from Microsoft. You can also provide the credentials to pull an image from a private repository. Once you fill out the necessary information, click Pull. Windows Admin Center will start the pull process on the container host. After the download is complete, you should see the new image on the Images tab.
Select the image you want to run, and click Run.
On the Run menu, set up the configuration for the container, such as the container name, the isolation type, which ports to publish, and memory and CPU allocation. Additionally, you can append Docker run commands that are not in the UI, such as -v for persistent volume. For more information on available Docker run parameters, review the documentation.
Once you have finished the configuration for the container, click Run. You can see the status of the running containers on the Containers tab:

Docker Desktop for Mac is the Community version of Docker for Mac.You can download Docker Desktop for Mac from Docker Hub.
MongoDB document databases provide high availability and easy scalability.
By downloading Docker Desktop, you agree to the terms of the Docker Software End User License Agreement and the Docker Data Processing Agreement.
Your Mac must meet the following requirements to successfully install Docker Desktop:
macOS must be version 10.14 or newer. That is, Mojave, Catalina, or Big Sur. We recommend upgrading to the latest version of macOS.
If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.
Docker supports Docker Desktop on the most recent versions of macOS. That is, the current release of macOS and the previous two releases. As new major versions of macOS are made generally available, Docker stops supporting the oldest version and supports the newest version of macOS (in addition to the previous two releases). Docker Desktop currently supports macOS Mojave, macOS Catalina, and macOS Big Sur.
At least 4 GB of RAM.
VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.
It is now possible to run Docker containers on Windows 10 and Windows Server, leveraging Ubuntu as a hosting base. Imagine running your own Linux applications on Windows, using a Linux distribution you are comfortable with: Ubuntu! It is now possible to do so using the power of Docker technology and Hyper-V virtualization on Windows. The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal. If you’ve just installed the app, Docker Desktop launches the onboarding tutorial. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub.

I admit it, I was not a friend of Oracle databases running in Docker containers for a long time. My database systems for testing and demo purposes were all running in VMware, Virtual Box or in the Oracle Cloud. But I have used the Windows Subsystem for Linux since beginning, to work with the Oracle Oracle Cloud Infrastructure CLI, Git Integration etc.. And what I really like is the WSL extension for Visual Studio Code which gives me to chance, to edit Ansible Vault files in Windows without any additional Linux based VM running.
With the update of the existing Windows Subsystem for Linux (WSL) architecture to version 2, the Docker Desktop for Windows is now fully integrated and able to run Docker container in WSL as a lightweight VM. Now it’s time to change my mind, why not use Docker to try out new Oracle features, do some development stuff and more?
What to we need to run Oracle databases in WSL 2 Docker Containers?
- WSL 2
- Docker Desktop for Windows
- Docker images with an Oracle Database – I may use the images (oehrlis/docker) from my workmate Stefan Oehrli (oradba.ch)- merci vöumou
This blog post shows you how to setup WSL 2 to run Docker images. Sure, you can use the Oracle provided Docker images or self created images too. But I have verified the Oracle repository today, the Dockerfile version is 19.3.0. And I don’t have the passion, to create new Dockerfiles for example to run 19.8 and download additional RU software.
