Get started with Docker for Windows

Estimated reading time: 26 minutes

Welcome to Docker for Windows!

Docker is a full development platform for creating containerized apps, and Docker for Windows is the best way to get started with Docker on Windows systems.

Already have Docker for Windows? If you already have Docker for Windows installed, and are ready to get started, skip down to Step 3. Check versions of Docker Engine, Compose, and Machine to work through the rest of the Docker for Windows tour, or jump over to getting started tutorials at Learn Docker.

Download Docker for Windows

If you have not already done so, please install Docker for Windows. You can download installers from the stable or beta channel. For more about stable and beta channels, see the FAQs.

Stable channel Beta channel
This installer is fully baked and tested, and comes with the latest GA version of Docker Engine.

This is the best channel to use if you want a reliable platform to work with.

These releases follow a version schedule with a longer lead time than the betas, synched with Docker Engine releases and hotfixes.

On the stable channel, you can select whether to send usage statistics and other data.
This installer offers cutting edge features and comes with the experimental version of Docker Engine, which is described in the Docker Experimental Features README on GitHub.

This is the best channel to use if you want to experiment with features under development, and can weather some instability and bugs. This channel is a continuation of the beta program, where you can provide feedback as the apps evolve. Releases are typically more frequent than for stable, often one or more per month.

We collect all usage data on betas across the board.

Important Notes:

  • Docker for Windows requires 64bit Windows 10 Pro, Enterprise and Education (1511 November update, Build 10586 or later) and Microsoft Hyper-V. Please see What to know before you install for a full list of prerequisites.

  • You can switch between beta and stable versions, but you must have only one app installed at a time. Also, you will need to save images and export containers you want to keep before uninstalling the current version before installing another. For more about this, see the FAQs about beta and stable channels.

What to know before you install

  • README FIRST for Docker Toolbox and Docker Machine users: Docker for Windows requires Microsoft Hyper-V to run. After Hyper-V is enabled, VirtualBox will no longer work, but any VirtualBox VM images will remain. VirtualBox VMs created with docker-machine (including the default one typically created during Toolbox install) will no longer start. These VMs cannot be used side-by-side with Docker for Windows. However, you can still use docker-machine to manage remote VMs.

  • The current version of Docker for Windows runs on 64bit Windows 10 Pro, Enterprise and Education (1511 November update, Build 10586 or later). In the future we will support more versions of Windows 10.

  • Containers and images created with Docker for Windows are shared between all user accounts on machines where it is installed. This is because all Windows accounts will use the same VM to build and run containers. In the future, Docker for Windows will better isolate user content.

  • The Hyper-V package must be enabled for Docker for Windows to work. The Docker for Windows installer will enable it for you, if needed. (This requires a reboot). If your system does not satisfy these requirements, you can install Docker Toolbox, which uses Oracle Virtual Box instead of Hyper-V.

  • Virtualization must be enabled. Typically, virtualization is enabled by default. (Note that this is different from having Hyper-V enabled.) For more detail see Virtualization must be enabled in Troubleshooting.

  • Nested virtualization scenarios, such as running Docker for Windows on a VMWare or Parallels instance, might work, but come with no guarantees (i.e., not officially supported).

About Windows containers and Windows Server 2016

Looking for information on using Windows containers?

  • Getting Started with Windows Containers (Lab) provides a tutorial on how to set up and run Windows containers on Windows 10 or with Windows Server 2016. It shows you how to use a MusicStore application with Windows containers.

Step 1. Install Docker for Windows

  1. Double-click InstallDocker.msi to run the installer.

    If you haven’t already downloaded the installer (InstallDocker.msi), you can get it here. It typically downloads to your Downloads folder, or you can run it from the recent downloads bar at the bottom of your web browser.

  2. Follow the install wizard to accept the license, authorize the installer, and proceed with the install.

    You will be asked to authorize Docker.app with your system password during the install process. Privileged access is needed to install networking components, links to the Docker apps, and manage the Hyper-V VMs.

  3. Click Finish on the setup complete dialog to launch Docker.

    Install complete>

Step 2. Start Docker for Windows

When the installation finishes, Docker starts automatically.

The whale in the status bar indicates that Docker is running, and accessible from a terminal.

If you just installed the app, you also get a popup success message with suggested next steps, and a link to this documentation.

Install success

When initialization is complete, select About Docker from the notification area icon to verify that you have the latest version.

Congratulations! You are up and running with Docker for Windows.

Step 3. Check versions of Docker Engine, Compose, and Machine

Start your favorite shell (cmd.exe, PowerShell, or other) to check your versions of docker and docker-compose, and verify the installation.

  PS C:\Users\jdoe> docker --version
  Docker version 1.12.0, build 8eab29e, experimental

  PS C:\Users\jdoe> docker-compose --version
  docker-compose version 1.8.0, build d988a55

  PS C:\Users\jdoe> docker-machine --version
  docker-machine version 0.8.0, build b85aac1

Step 4. Explore the application and run examples

The next few steps take you through some examples. These are just suggestions for ways to experiment with Docker on your system, check version information, and make sure docker commands are working properly.

  1. Open a shell (cmd.exe, PowerShell, or other).

  2. Run some Docker commands, such as docker ps, docker version, and docker info.

    Here is the output of docker ps run in a powershell. (In this example, no containers are running yet.)

       PS C:\Users\jdoe> docker ps
    
       CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
    

    Here is an example of command output for docker version.

       PS C:\Users\jdoe> docker version
       Client:
       Version:      1.13.0-rc3
       API version:  1.25

    Note: The outputs above are examples. Your output for commands like docker version and docker info will vary depending on your product versions (e.g., as you install newer versions).

  3. Run docker run hello-world to test pulling an image from Docker Hub and starting a container.

      PS C:\Users\jdoe> docker run hello-world
    
      Hello from Docker.
      This message shows that your installation appears to be working correctly.
    
      To generate this message, Docker took the following steps:
      1. The Docker client contacted the Docker daemon.
      2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
      3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading.
      4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.
    
  4. Try something more ambitious, and run an Ubuntu container with this command.

       docker run -it ubuntu bash
    

    This will download the ubuntu container image and start it. Here is the output of running this command in a powershell.

       PS C:\Users\jdoe> docker run -it ubuntu bash
    
       Unable to find image 'ubuntu:latest' locally
       latest: Pulling from library/ubuntu
       5a132a7e7af1: Pull complete
       fd2731e4c50c: Pull complete
       28a2f68d1120: Pull complete
       a3ed95caeb02: Pull complete

       Status: Downloaded newer image for ubuntu:latest
    

    Type exit to stop the container and close the powershell.

  5. Start a Dockerized webserver with this command:

       docker run -d -p 80:80 --name webserver nginx
    

    This will download the nginx container image and start it. Here is the output of running this command in a powershell.

       PS C:\Users\jdoe> docker run -d -p 80:80 --name webserver nginx
    
       Unable to find image 'nginx:latest' locally
       latest: Pulling from library/nginx
    
       fdd5d7827f33: Pull complete
       a3ed95caeb02: Pull complete
       716f7a5f3082: Pull complete

       Status: Downloaded newer image for nginx:latest
       dfe13c68b3b86f01951af617df02be4897184cbf7a8b4d5caf1c3c5bd3fc267f
    
  6. Point your web browser at http://localhost to display the start page.

    (Since you specified the default HTTP port, it isn’t necessary to append :80 at the end of the URL.)

    Run nginx edge>

  7. Run docker ps while your webserver is running to see details on the container.

      PS C:\Users\jdoe> docker ps
    
      CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS
      NAMES
      dfe13c68b3b8        nginx               "nginx -g 'daemon off"   3 days ago          Up 45 seconds       0.0.0.0:80->80/tcp, 443/tc
      p   webserver
    
  8. Stop or remove containers and images.

    The nginx webserver will continue to run in the container on that port until you stop and/or remove the container. If you want to stop the webserver, type: docker stop webserver and start it again with docker start webserver.

    To stop and remove the running container with a single command, type: docker rm -f webserver. This will remove the container, but not the nginx image. You can list local images with docker images. You might want to keep some images around so that you don’t have to pull them again from Docker Hub. To remove an image you no longer need, use docker rmi <imageID>|<imageName>. For example, docker rmi nginx.

Set up tab completion in PowerShell

If you would like to have handy tab completion for Docker commands, you can install the posh-docker PowerShell Module as follows.

  1. Start an “elevated” PowerShell (i.e., run it as administrator).

    To do this, search for PowerShell, right-click, and choose Run as administrator.

    Run PowerShell as administrator

    When asked if you want to allow this app to make changes to your device, click Yes.

  2. Set the script execution policy to allow downloaded scripts signed by trusted publishers to run on your computer. To do so, type this at the PowerShell prompt.
    Set-ExecutionPolicy RemoteSigned
    To check that the policy is set properly, run get-executionpolicy, which should return RemoteSigned.
  3. To enable auto-completion of commands for the current PowerShell only, type:

    Install-Module posh-docker

  4. To make tab completion persistent across all PowerShell sessions, add the command to a $PROFILE by typing these commands at the PowerShell prompt.

     Install-Module -Scope CurrentUser posh-docker -Force
     Add-Content $PROFILE "`nInstall-Module posh-docker"
    

    This creates a $PROFILE if one does not already exist, and adds this line into the file:

    Install-Module posh-docker


    To check that the file was properly created, or simply edit it manually, type this in PowerShell:

    Notepad $PROFILE

Now, when you press tab after typing the first few letters, Docker commands such as start, stop, run, and their options, along with container and image names should now auto-complete.

Docker Settings

When Docker is running, the Docker whale is displayed. By default, the Docker whale icon is placed in the Notifications area. If it is hidden, click the up arrow on the taskbar to show it.

Tip: You can pin the whale outside of the notification box so that it is always visible on the taskbar. To do this, drag-and-drop the whale icon. Or, right-click an empty porition of the taskbar, select Settings, and choose display options through taskbar settings for notifications.

Showing hidden apps in the taskbar

To get a popup menu with application options, right-click the whale:

Docker for Windows popup menu

The Settings dialogs provide options to allow Docker auto-start, automatically check for updates, share local drives with Docker containers, enable VPN compatibility, manage CPUs and memory Docker uses, restart Docker, or perform a factory reset.

General

Settings

  • Start Docker when you log in - Automatically start the Docker for Windows application upon Windows system login.

  • Check for updates when the application starts - Docker for Windows is set to automatically check for updates and notify you when an update is available. If an update is found, click OK to accept and install it (or cancel to keep the current version). Uncheck this option if you do not want notifications of version upgrades. You can still find out about updates manually by choosing Check for Updates from the menu.

  • Send usage statistics - You can set Docker for Windows to auto-send diagnostics, crash reports, and usage data. This information can help Docker improve the application and get more context for troubleshooting problems.

    Uncheck any of the options to opt out and prevent auto-send of data. Docker may prompt for more information in some cases, even with auto-send enabled. Also, you can enable or disable these auto-reporting settings with one click on the information popup when you first start Docker.

    Startup information

Shared Drives

Share your local drives (volumes) with Docker for Windows, so that they are available to your containers.

Shared Drives

You will be asked to provide your Windows system username and password (domain user) to apply shared drives. You can select an option to have Docker store the credentials so that you don’t have to re-enter them every time.

Permissions to access shared drives are tied to the credentials you provide here. If you run docker commands and tasks under a different username than the one used here to set up sharing, your containers will not have permissions to access the mounted volumes.

Tip: Shared drives are only required for volume mounting Linux containers, and not for Windows containers. For Linux containers, you need to share the drive where your project is located (i.e., where the Dockerfile and volume are located). Runtime errors such as file not found or cannot start service may indicate shared drives are needed. (See also Volume mounting requires shared drives for Linux containers.)

See also Verify domain user has permissions for shared drives in Troubleshooting.

Note: You can share local drives with your containers but not with Docker Machine nodes. See Can I share local drives and filesystem with my Docker Machine VMs? in the FAQs.

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.

Note: In Docker for Windows Beta 29 and higher, Docker detects if port 445 is closed and shows the following message when you try to add a shared drive: Port 445 blocked

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 port 445 (the Windows host) from 10.0.75.2 (the virtual machine).

Advanced

CPU and Memory settings

  • CPUs - Change the number of processors assigned to the Linux VM.

  • Memory - Change the amount of memory the Docker for Windows Linux VM uses.

Please note, updating these settings requires a reconfiguration and reboot of the Linux VM. This will take a few seconds.

Network

You can configure Docker for Windows 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.

Network settings

Note: Some users reported problems connecting to Docker Hub on Docker for Windows stable version. This would manifest as an error when trying to run docker commands 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: 8.8.8.8. For more information, see Networking issues in Troubleshooting.

Note that updating these settings requires a reconfiguration and reboot of the Linux VM.

Proxies

Docker for Windows lets you configure HTTP/HTTPS Proxy Settings and automatically propagate these to Docker and to your containers. For example, if you set your proxy settings to http://proxy.example.com, Docker will use this proxy when pulling containers.

Proxies

When you start a container, you will see that your proxy settings propagate into the containers. For example:

PS C:\Users\jdoe> docker run -it 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

You can see from the above output that the HTTP_PROXY, http_proxy and no_proxy environment 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 restart policies

Docker daemon

You can configure options on the Docker daemon that determine how your containers will run. You can configure some Basic options on the daemon with interactive settings, or switch to Advanced to edit the JSON directly.

The settings offered on Basic dialog can be configured directly in the JSON as well. This version just surfaces some of the commmon settings to make it easier to configure them.

Docker Daemon

Experimental mode

By default, Docker for Windows Beta releases use the experimental version of Docker Engine, described in the Docker Experimental Features README on GitHub. Starting with Beta 34 and Stable 1.13.0, you can toggle experimental mode on and off via the Basic Daemon settings. If you toggle it off, Docker for Windows Beta uses the current generally available release of Docker Engine, the same as Stable Docker for Windows versions uses by default.

You can check whether you are running experimental mode or not by typing docker version in a PowerShell. Experimental mode is listed under Server data. If Experimental is true, then Docker is running in experimental mode, as shown here. (If false, Experimental mode is off.)

Custom registries

Also starting with with Beta 34 and Stable 1.13.0, you can set up your own registries on the Basic Daemon settings.

As an alternative to using Docker Hub to store your public or private images or Docker Trusted Registry, you can use Docker to set up your own insecure registry. Add URLs for insecure registries and registry mirrors on which to host your images. (See also, How do I add custom CA certificates? in the FAQs.)

Edit the daemon configuration file

The Advanced daemon settings provide the original option to directly edit the JSON configuration file for the <a href=”/engine/reference/commandline/dockerd/>daemon</a>.

Docker Daemon

For a full list of options on the Docker daemon, see daemon in the Docker Engine command line reference.

In that topic, see also:

Note that updating these settings requires a reconfiguration and reboot of the Linux VM.

Switch between Windows and Linux containers

Starting with Beta 26 and Stable 1.13.0, you can select which daemon (Linux or Windows) the Docker CLI talks to. Select Switch to Windows containers to toggle to Windows containers. Select Switch to Linux containers.

Microsoft Developer Network has preliminary/draft information on Windows containers here.

For a full list of options on the Docker daemon, see daemon in the Docker Engine command line reference.

Getting started with Windows containers

If you are interested in working with Windows containers, here are some guides to help you get started.

About the Docker Windows containers specific dialogs

When you switch to Windows containers, the Settings panel updates to show only those dialogs that are active and apply to your Windows containers:

Keep in mind that 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.

The following settings are not available in Windows containers mode, because they do not apply to Windows containers:
