Welcome to Docker Desktop!
This page contains information about Docker Desktop Community (Stable and Edge) releases. For information about Docker Desktop Enterprise (DDE) releases, see Docker Desktop Enterprise.
Docker is a full development platform for creating containerized applications. Docker Desktop is the best way to get started with Docker on Windows.
See Install Docker Desktop for information on system requirements and Stable and Edge channels.
Test your installation
Open a terminal window (Command Prompt or PowerShell, but not PowerShell ISE).
docker --versionto ensure that you have a supported version of Docker:
> docker --version Docker version 19.03.1
Pull the hello-world image from Docker Hub and run a container:
> docker run hello-world docker : Unable to find image 'hello-world:latest' locally ... latest: Pulling from library/hello-world ca4f61b1923c: Pulling fs layer ca4f61b1923c: Download complete ca4f61b1923c: Pull complete Digest: sha256:97ce6fa4b6cdc0790cda65fe7290b74cfebd9fa0c9b8c38e979330d547d22ce1 Status: Downloaded newer image for hello-world:latest Hello from Docker!

Explore the application
In this section, we demonstrate the ease and power of Dockerized applications by running something more complex, such as an OS and a webserver.
Pull an image of the Ubuntu OS and run an interactive terminal inside the spawned container:
> docker run --interactive --tty ubuntu bash docker : Unable to find image 'ubuntu:latest' locally ... latest: Pulling from library/ubuntu 22dc81ace0ea: Pulling fs layer 1a8b3c87dba3: Pulling fs layer 91390a1c435a: Pulling fs layer ...

Do not use PowerShell ISE
Interactive terminals do not work in PowerShell ISE (but they do in PowerShell). See docker/for-win/issues/223.
You are in the container. At the root
#prompt, check the
hostnameof the container:
root@8aea0acb7423:/# hostname 8aea0acb7423
Notice that the hostname is assigned as the container ID (and is also used in the prompt).
Exit the shell with the
exitcommand (which also stops the container):
root@8aea0acb7423:/# exit >
List containers with the
--alloption (because no containers are running).

Docker Settings dialog
The Docker Desktop menu allows you to configure your Docker settings such as installation, updates, version channels, Docker Hub login, and more.
This section explains the configuration options accessible from the Settings dialog.
Open the Docker Desktop menu by clicking the Docker icon in the Notifications area (or System tray):
Select Settings to open the Settings dialog:
On the General tab of the Settings dialog, you can configure when to start and update Docker.
Start Docker when you log in - Automatically start Docker Desktop upon Windows system login.
Automatically check for updates - By default, Docker Desktop automatically checks for updates and notifies you when an update is available. Click OK to accept and install updates (or cancel to keep the current version). You can manually update by choosing Check for Updates from the main Docker menu.
Send usage statistics - By default, Docker Desktop sends diagnostics, crash reports, and usage data. This information helps Docker improve and troubleshoot the application. Clear the check box to opt out. Docker may periodically prompt you for more information.
Expose daemon on tcp://localhost:2375 without TLS - Click this option to enable legacy clients to connect to the Docker daemon. You must use this option with caution as exposing the daemon without TLS can result in remote code execution attacks.
Share your local drives (volumes) with Docker Desktop, so that they are available to your Linux containers.
Permission for shared drives are tied to the credentials you provide here. If
docker commands under a different username than the one configured
here, your containers cannot access the mounted volumes.
To apply shared drives, you are prompted for your Windows system (domain) username and password. You can select an option to have Docker store the credentials so that you don’t need to enter them every time.
Tips on shared drives, permissions, and volume mounts
Shared drives are only required for mounting volumes in Linux containers, not for Windows containers. For Linux containers, you need to share the drive where the Dockerfile and volume are located. If you get errors such as
file not foundor
cannot start serviceyou may need to enable shared drives. See Volume mounting requires shared drives for Linux containers.)
If possible, avoid volume mounts from the Windows host, and instead mount on the Linux VM, or use a data volume (named volume) or data container. There are a number of issues with using host-mounted volumes and network paths for database files. See Volume mounts from host paths use a nobrl option to override database locking.
Docker Desktop sets permissions to read/write/execute for users, groups and others 0777 or a+rwx. This is not configurable. See Permissions errors on data directories for shared volumes.
Ensure the domain user has access to shared drives, as described in Verify domain user has permissions for shared drives.
You can share local drives with your containers but not with Docker Machine nodes. See the FAQ, Can I share local drives and filesystem with my Docker Machine VMs?.
Firewall rules for shared drives
Shared drives require port 445 to be open between the host machine and the virtual machine that runs Linux containers. Docker detects if port 445 is closed and shows the following message when you try to add a shared drive:
To share the drive, allow connections between the Windows host machine and the virtual machine in Windows Firewall or your third party firewall software. You do not need to open port 445 on any other network.
By default, allow connections to
10.0.75.1 on port 445 (the Windows host) from
10.0.75.2 (the virtual machine). If your firewall rules seem correct, you may
need to toggle or
reinstall the File and Print sharing service on the Hyper-V virtual network card
Shared drives on demand
You can share a drive “on demand” the first time a particular mount is requested.
If you run a Docker command from a shell with a volume mount (as shown in the example below) or kick off a Compose file that includes volume mounts, you get a popup asking if you want to share the specified drive.
You can select to Share it, in which case it is added your Docker Desktop Shared Drives list and available to containers. Alternatively, you can opt not to share it by selecting Cancel.
The Linux VM restarts after changing the settings on the Advanced tab. This takes a few seconds.
CPUs - Change the number of processors assigned to the Linux VM.
Memory - Change the amount of memory the Docker Desktop Linux VM uses.
Swap - Configure the swap file size.
You can configure Docker Desktop networking to work on a virtual private network (VPN).
Internal Virtual Switch - You can specify a network address translation (NAT) prefix and subnet mask to enable Internet connectivity.
DNS Server - You can configure the DNS server to use dynamic or static IP addressing.
Note: Some users reported problems connecting to Docker Hub on Docker Desktop Stable version. This would manifest as an error when trying to run
dockercommands that pull images from Docker Hub that are not already downloaded, such as a first time run of
docker run hello-world. If you encounter this, reset the DNS server to use the Google DNS fixed address:
126.96.36.199. For more information, see Networking issues in Troubleshooting.
Updating these settings requires a reconfiguration and reboot of the Linux VM.
Docker Desktop lets you configure HTTP/HTTPS Proxy Settings and
automatically propagates these to Docker and to your containers. For example,
if you set your proxy settings to
http://proxy.example.com, Docker uses this
proxy when pulling containers.
When you start a container, your proxy settings propagate into the containers. For example:
> docker run alpine env PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin HOSTNAME=b7edf988b2b5 TERM=xterm HOME=/root HTTP_PROXY=http://proxy.example.com:3128 http_proxy=http://proxy.example.com:3128 no_proxy=*.local, 169.254/16
In the output above, the
variables are set. When your proxy configuration changes, Docker restarts
automatically to pick up the new settings. If you have containers that you wish
to keep running across restarts, you should consider using
You can configure the Docker daemon to hone how your containers run. Advanced mode lets you edit the JSON directly. Basic mode lets you configure the common daemon options with interactive settings.
Docker Desktop Edge releases have the experimental version of Docker Engine enabled by default, described in the Docker Experimental Features README on GitHub.
Experimental features provide early access to future product functionality. These features are intended for testing and feedback only as they may change between releases without warning or can be removed entirely from a future release. Experimental features must not be used in production environments. Docker does not offer support for experimental features. For more information, see Experimental features.
To enable experimental features in the Docker CLI, edit the
config.jsonfile and set
To enable experimental features from the Docker Desktop menu, click Settings (Preferences on macOS) > Daemon and then select the Experimental features check box.
On both Edge and Stable releases, you can toggle the Experimental features on and off. If you toggle it off, Docker Desktop uses the current generally available release of Docker Engine.

You can set up your own registries on the Basic Daemon settings.
Normally, you store public or private images in Docker Hub and Docker Trusted Registry. Here, you can use Docker to set up your own insecure registry. Simply add URLs for insecure registries and registry mirrors on which to host your images.
Daemon configuration file
The Advanced daemon settings provide the original option to directly edit the JSON configuration file for the daemon.
Updating these settings requires a reconfiguration and reboot of the Linux VM.
For a full list of options on the Docker daemon, see daemon, and also sub-topics:
Docker Desktop includes a standalone Kubernetes server that runs on your Windows host, so that you can test deploying your Docker workloads on Kubernetes.
The Kubernetes client command,
kubectl, is included and configured to connect
to the local Kubernetes server. If you have
kubectl already installed and
pointing to some other environment, such as
minikube or a GKE cluster, be sure
to change context so that
kubectl is pointing to
> kubectl config get-contexts > kubectl config use-context docker-for-desktop
You can also change it through the Docker Desktop menu:
If you installed
kubectl by another method, and
experience conflicts, remove it.
To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable Kubernetes and click the Apply button. This instantiates images required to run the Kubernetes server as containers, and installs the
kubectl.execommand in the path.
By default, Kubernetes containers are hidden from commands like
docker service ls, because managing them manually is not supported. To make them visible, select Show system containers (advanced) and click Apply. Most users do not need this option.
To disable Kubernetes support at any time, deselect Enable Kubernetes. The Kubernetes containers are stopped and removed, and the
/usr/local/bin/kubectlcommand is removed.
For more information on using the Kubernetes integration with Docker Desktop, see Deploy on Kubernetes.
Reset and Restart options
On Edge releases, the Restart Docker Desktop, Reset Kubernetes Cluster, and Reset to factory defaults options are available on the Troubleshoot menu.
On Stable releases, you can restart Docker or reset its configuration using the Reset tab.
Restart Docker Desktop - Shuts down and restarts the Docker application.
Reset Kubernetes Cluster - Deletes all stacks and Kubernetes resources.
Reset to factory defaults - Resets Docker to factory defaults. This is useful in cases where Docker stops working or becomes unresponsive.

Switch between Windows and Linux containers
From the Docker Desktop menu, you can toggle which daemon (Linux or Windows) the Docker CLI talks to. Select Switch to Windows containers to use Windows containers, or select Switch to Linux containers to use Linux containers (the default).
For more information on Windows containers, refer to the following documentation:
Microsoft documentation on Windows containers.
Build and Run Your First Windows Server Container (Blog Post) gives a quick tour of how to build and run native Docker Windows containers on Windows 10 and Windows Server 2016 evaluation releases.
Getting Started with Windows Containers (Lab) shows you how to use the MusicStore application with Windows containers. The MusicStore is a standard .NET application and, forked here to use containers, is a good example of a multi-container application.
To understand how to connect to Windows containers from the local host, see Limitations of Windows containers for
localhostand published ports
Settings dialog changes with Windows containers
When you switch to Windows containers, the Settings dialog only shows those tabs that are active and apply to your Windows containers:
If you set proxies or daemon configuration in Windows containers mode, these apply only on Windows containers. If you switch back to Linux containers, proxies and daemon configurations return to what you had set for Linux containers. Your Windows container settings are retained and become available again when you switch back.
