- How To Install Docker on Windows? A Step-by-Step Guide [Updated]
Get Up and Running with Docker for Windows.Get started with Docker containers on WSL | Microsoft Docs
NET application and "dockerizing" it and then improving it. In just an hour he'd ended up with a solution featuring eight containers - the original ASP. Normally something like this would take the best part of a day to get installed on your computer and configured correctly, but he was able to run the whole thing with a simple docker-compose up -d command. I was seriously impressed. But would I be able to replicate his demo, or was it all smoke and mirrors?
I set myself the challenge of trying to run Elton's demo myself, by cloning his git repository , and running docker-compose. Now if you're new to Docker, knowing what you are supposed to install for Windows can get quite confusing as there are a few flavours of Docker for Windows support. In this post, I'm going to focus on two main options. First, using Docker on your Windows 10 Pro development machine.
And second, using Docker on a Windows Server which is what you'd typically use for running Windows Docker containers in production. So for running Docker containers on a Windows 10 development machine, we need a few things. First of all, we need the Hyper-V feature of Windows enabled.
That means that Win 10 Home is not good enough — you do need the Pro edition. Second, make sure you have installed the latest Windows 10 updates. We'll also need git installed for this demo. Next, we need to install Docker for Windows.
The good news is that as of very recently v1. This is another potentially confusing thing about running Docker on Windows. It offers you a way to use any of the myriad of existing Linux-based containers on Docker Hub , by virtue of a Linux VM it creates for you.
But it also lets you use the brand new Windows containers, which is the type of container we're using in this demo. The Docker for Windows installer may need to reboot your machine to install key Windows features, but once its running you'll have a Docker icon in your system tray, and if you go to a command prompt you can type docker version to check it is installed correctly.
Don't worry, it's not as scary as it sounds, you can switch easily back and forth between the two as required. For trying this out on a Windows Server , you need a fresh install of Windows Server , and then run Windows Update to get all up to date.
Now for Windows Server, we're not going to install Docker for Windows. Instead, we are simply going to enable the container feature of Windows This will let us run Windows Docker containers which are now a first-class citizen of Windows.
You configure Docker for Windows Server with the following PowerShell instructions run from an administrator prompt :. With this in place, you should be able to go to a command prompt and type docker version and see that it is correctly installed. Another thing you can do to check all is well is check that the Docker service is running, which you can do with the Get-Service docker command:.
If it shows as Stopped , then go ahead and start it with Start-Service docker. For this demo we will need a couple more things installed on our Windows Server.
We'll need git installed, and we also want the docker-compose utility. But it's a real pain installing anything on Windows Server, as it comes with a locked down IE browser that will fight against you downloading anything. So we'll install chocolatey from an administrator PowerShell prompt. I'm working off the v5 version — commit 55ab6f3. This will cause a few things to happen. First of all, it will pull all the necessary Docker images to run this app.
The good news is that this is a one-time operation. Very often you'll reuse the same base images many times over. If all goes well, you should be able to run the docker ps command to see them all running. Now on Windows Server , this worked perfectly first time!
It wasn't quite as plain sailing on Windows 10, but the problems weren't too difficult to resolve. First of all, docker-compose refused to run at all, complaining I had the wrong version of the tool. I discovered that by editing the docker-compose. And second, some of my Docker containers failed to start up first time. What we can do to trouble-shoot, is use the docker logs command to see the log output for a specific container. By the way, you can safely keep calling the docker-compose up -d command until everything starts up correctly.
It works out what still needs to be done. So with these changes in place, docker-compose up was able to start up the full solution. But of course, I wasn't happy with just seeing eight containers running. I wanted to know that the app was really functioning. So how can we test Elton's app and prove that our containers really are all communicating with one another?
First of all we need to check the website is running. To do that, we need to find out what the IP address of the website container is. Note that this IP address will be different every time we restart our containers. In my example the IP address is This is actually proving that two containers are working, since the launch page is pulled from a second container running a webserver on another port.
This connects to the database container, and runs sqlcmd with the specified username and password the password that was specified as an environment variable in the docker-compose. We just have one more test to perform to prove out the remaining containers. Did the data also make it into elasticsearch? We can use the kibana container to check. This tells me my kibana is running on Once this has been done you confirm the index mapping and head to the Discover tab where we should see the details we entered appear:.
And all in a fraction of the time it would have taken to manually get this up and running on my developer machine and without me needing to install things like Java and elasticsearch just to try out this demo app.
But the ones specific to this demo you might want to get rid of. The easiest way to clean up in this instance is to use docker-compose down which will stop and remove all the containers created for this demo app. But you will also want to learn some basic commands like docker ps -a to see all containers, docker stop to stop a running container and docker rm to remove a container.
And the docker volume ls and docker volume rm will let you explore and clean up images. Pretty much any Docker training course or tutorial will give you details on these and many other useful docker commands. The containerized approach has tremendous benefits for streamlining the development and testing experience, as well as simplifying deployment.
What OS? Another thing you can do to check all is well is check that the Docker service is running, which you can do with the Get-Service docker command: If it shows as Stopped , then go ahead and start it with Start-Service docker. Troubleshooting on Windows 10 It wasn't quite as plain sailing on Windows 10, but the problems weren't too difficult to resolve.

But before we learn about the installation process, let us first understand what Docker is. Docker is an OS-level virtualization software platform that helps users in building and managing applications in the Docker environment with all its library dependencies.
Note: Docker Container is a lightweight software package that includes all the dependencies frameworks, libraries, etc. Note: Suppose the installer Docker Desktop Installer. Once you start the installation process, always enable Hyper-V Windows Feature on the Configuration page.
Then, follow the installation process to allow the installer and wait till the process is done. After the installation process is complete, the tool does not start automatically.
To start the Docker tool, search for the tool, and select Docker Desktop in your desktop search results. Before starting the application, Docker offers an onboarding tutorial. The tutorial explains how to build a Docker image and run a container. Congratulations, Docker Installation on Windows is now done, and now, you are ready to build and run Docker images and containers on the Docker ecosystem.
You can install Docker Toolbox if you have a bit version of Windows 7 or later. Alternately, you do have the option to upgrade. Docker for Windows enables Hyper-V if necessary; this requires a reboot.
Installation Download Docker. Double-click InstallDocker. Follow the Install Wizard: accept the license, authorize the installer, and proceed with the install. Click Finish to launch Docker. However, while Docker Desktop supports running both Linux and Windows containers, you can not run both simultaneously.
To run Linux and Windows containers simultaneously, you would need to install and run a separate Docker instance in WSL. If you need to run simultaneous containers or just prefer to install a container engine directly in your Linux distribution, follow the Linux installation instructions for that container service, such as Install Docker Engine on Ubuntu or Install Podman for running Linux containers.
Docker is a tool used to create, deploy, and run applications using containers. Containers enable developers to package an app with all of the parts it needs libraries, frameworks, dependencies, etc and ship it all out as one package. Using a container ensures that the app will run the same regardless of any customized settings or previously installed libraries on the computer running it that could differ from the machine that was used to write and test the app's code. This permits developers to focus on writing code without worrying about the system that code will be run on.
Docker containers are similar to virtual machines, but don't create an entire virtual operating system. Instead, Docker enables the app to use the same Linux kernel as the system that it's running on.
This allows the app package to only require parts not already on the host computer, reducing the package size and improving performance. Continuous availability, using Docker containers with tools like Kubernetes , is another reason for the popularity of containers.
This enables multiple versions of your app container to be created at different times. Rather than needing to take down an entire system for updates or maintenance, each container and it's specific microservices can be replaced on the fly. You can prepare a new container with all of your updates, set up the container for production, and just point to the new container once it's ready.
You can also archive different versions of your app using containers and keep them running as a safety fallback if needed. To learn more, checkout the Introduction to Docker containers on Microsoft Learn. You can check this by opening PowerShell and entering: wsl -l -v. Ubuntu This means that Linux containers can run natively without emulation, resulting in better performance and interoperability between your Windows and Linux tools.
With the WSL 2 backend supported in Docker Desktop for Windows, you can work in a Linux-based development environment and build Linux-based containers, while using Visual Studio Code for code editing and debugging, and running your container in the Microsoft Edge browser on Windows. To install Docker after already installing WSL :. Download Docker Desktop and follow the installation instructions.
