Installing Docker on Windows 10 Home edition is like trying to put a square peg in a round hole with your hands tied behind your back, during a hail storm while running away from a bipolar. Just because Docker only supported containers in Hyper-V mode on Windows 10, which my laptop did not really like in combination with other native Hyper-V VM’s. Since Docker supports process isolation on Windows 10 (starting with version 1809) it became time to say goodbye to my Hyper-V setup and switch to running containers directly on. Docker’s comprehensive end to end platform includes UIs, CLIs, APIs and security that are engineered to work together across the entire application delivery lifecycle. Build Get a head start on your coding by leveraging Docker images to efficiently develop your own unique applications on Windows and Mac. If you’ve ever tried to install Docker for Windows, you’ve probably came to realize that the installer won’t run on Windows 10 Home.Only Windows Pro, Enterprise or Education support Docker.
Welcome to Docker Desktop! The Docker Desktop for Windows user manual provides information on how to configure and manage your Docker Desktop settings.
For information about Docker Desktop download, system requirements, and installation instructions, see Install Docker Desktop.
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 GeneralIC-9700.xml. 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.
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.
Send usage statistics - By default, Docker Desktop sends diagnostics,crash reports, and usage data. This information helps Docker improve andtroubleshoot the application. Clear the check box to opt out. Docker may periodically prompt you for more information.
The Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources. Different settings are available for configuration depending on whether you are using Linux containers in WSL 2 mode, Linux containers in Hyper-V mode, or Windows containers.
The Advanced tab is only available in Hyper-V mode, because in WSL 2 mode and Windows container mode these resources are managed by Windows. In WSL 2 mode, you can configure limits on the memory, CPU, and swap size allocatedto the WSL 2 utility VM.
Use the Advanced tab to limit resources available to Docker.
CPUs: By default, Docker Desktop is set to use half the number of processorsavailable on the host machine. To increase processing power, set this to ahigher number; to decrease, lower the number.
Memory: By default, Docker Desktop is set to use
2 GB runtime memory,allocated from the total available memory on your machine. To increase the RAM, set this to a higher number. To decrease it, lower the number.
Swap: Configure swap file size as needed. The default is 1 GB.
Disk image size: Specify the size of the disk image.
Disk image location: Specify the location of the Linux volume where containers and images are stored.
You can also move the disk image to a different location. If you attempt to move a disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it.
The File sharing tab is only available in Hyper-V mode, because in WSL 2 mode and Windows container mode all files are automatically shared by Windows.
Use File sharing to allow local directories on Windows to be shared with Linux containers.This is especially useful forediting source code in an IDE on the host while running and testing the code in a container.Note that configuring file sharing is not necessary for Windows containers, only Linux containers. If a directory is not shared with a Linux container you may get
file not found or
cannot start service errors at runtime. See Volume mounting requires shared folders for Linux containers.
File share settings are:
Add a Directory: Click
+and navigate to the directory you want to add.
Apply & Restart makes the directory available to containers using Docker’sbind mount (
Tips on shared folders, permissions, and volume mounts
Share only the directories that you need with the container. File sharing introduces overhead as any changes to the files on the host need to be notified to the Linux VM. Sharing too many files can lead to high CPU load and slow filesystem performance.
Shared folders are designed to allow application code to be edited on the host while being executed in containers. For non-code items such as cache directories or databases, the performance will be much better if they are stored in the Linux VM, using a data volume (named volume) or data container.
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.
Windows presents a case-insensitive view of the filesystem to applications while Linux is case-sensitive. On Linux it is possible to create 2 separate files:
Test, while on Windows these filenames would actually refer to the same underlying file. This can lead to problems where an app works correctly on a developer Windows machine (where the file contents are shared) but fails when run in Linux in production (where the file contents are distinct). To avoid this, Docker Desktop insists that all shared files are accessed as their original case. Therefore if a file is created called
test, it must be opened as
test. Attempts to open
Testwill fail with “No such file or directory”. Similarly once a file called
testis created, attempts to create a second file called
Shared folders on demand
You can share a folder “on demand” the first time a particular folder is used by a container.
If you run a Docker command from a shell with a volume mount (as shown in theexample below) or kick off a Compose file that includes volume mounts, you get apopup asking if you want to share the specified folder.
You can select to Share it, in which case it is added your Docker Desktop Shared Folders list and available tocontainers. Alternatively, you can opt not to share it by selecting Cancel.
Docker Desktop lets you configure HTTP/HTTPS Proxy Settings andautomatically propagates these to Docker. For example, if you set your proxysettings to
http://proxy.example.com, Docker uses this proxy when pulling containers.
Your proxy settings, however, will not be propagated into the containers you start.If you wish to set the proxy settings for your containers, you need to defineenvironment variables for them, just like you would do on Linux, for example:
For more information on setting environment variables for running containers,see Set environment variables.
The Network tab is not available in Windows container mode because networking is managed by Windows.
You can configure Docker Desktop networking to work on a virtual private network (VPN). 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.
Some users reported problems connecting to Docker Hub on Docker Desktop. This would manifest as an error when trying to run
docker commands that pull images from Docker Hub that are not alreadydownloaded, such as a first time run of
docker run hello-world. If youencounter this, reset the DNS server to use the Google DNS fixed address:
184.108.40.206. For more information, seeNetworking issues in Troubleshooting.
Updating these settings requires a reconfiguration and reboot of the Linux VM.
In WSL 2 mode, you can configure which WSL 2 distributions will have the Docker WSL integration.
By default, the integration will be enabled on your default WSL distribution. To change your default WSL distro, run
wsl --set-default <distro name>. (For example, to set Ubuntu as your default WSL distro, run
wsl --set-default ubuntu).
You can also select any additional distributions you would like to enable the WSL 2 integration on.
For more details on configuring Docker Desktop to use WSL 2, see Docker Desktop WSL 2 backend.
The Docker Engine page allows you to configure the Docker daemon to determine how your containers run.
Type a JSON configuration file in the box to configure the daemon settings. For a full list of options, see the Docker Enginedockerd commandline reference.
Click Apply & Restart to save your settings and restart Docker Desktop.
On the Command Line page, you can specify whether or not to enable experimental features.
You can toggle the experimental features on and off in Docker Desktop. If you toggle the experimental features off, Docker Desktop uses the current generally available release of Docker Engine.
Experimental features provide early access to future product functionality.These features are intended for testing and feedback only as they may changebetween releases without warning or can be removed entirely from a futurerelease. Experimental features must not be used in production environments.Docker does not offer support for experimental features.
For a list of current experimental features in the Docker CLI, see Docker CLI Experimental features.
docker version to verify whether you have enabled experimental features. Experimental modeis listed under
Server data. If
true, then Docker isrunning in experimental mode, as shown here:
The Kubernetes tab is not available in Windows container mode.
Docker Desktop includes a standalone Kubernetes server that runs on your Windows machince, sothat you can test deploying your Docker workloads on Kubernetes. To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable Kubernetes.
For more information about using the Kubernetes integration with Docker Desktop, see Deploy on Kubernetes.
The Restart Docker Desktop and Reset to factory defaults options are now available on the Troubleshoot menu. For information, see Logs and Troubleshooting.

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 Windowscontainers, 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 MusicStoreapplication 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, seeLimitations 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, theseapply only on Windows containers. If you switch back to Linux containers,proxies and daemon configurations return to what you had set for Linuxcontainers. Your Windows container settings are retained and become availableagain when you switch back.
The Docker Desktop Dashboard enables you to interact with containers and applications and manage the lifecycle of your applications directly from your machine. The Dashboard UI shows all running, stopped, and started containers with their state. It provides an intuitive interface to perform common actions to inspect and manage containers and Docker Compose applications. For more information, see Docker Desktop Dashboard.
Select Sign in /Create Docker ID from the Docker Desktop menu to access your Docker Hub account. Once logged in, you can access your Docker Hub repositories directly from the Docker Desktop menu.
For more information, refer to the following Docker Hub topics:
Docker Desktop enables you to sign into Docker Hub using two-factor authentication. Two-factor authentication provides an extra layer of security when accessing your Docker Hub account.
You must enable two-factor authentication in Docker Hub before signing into your Docker Hub account through Docker Desktop. For instructions, see Enable two-factor authentication for Docker Hub.
After you have enabled two-factor authentication:
Go to the Docker Desktop menu and then select Sign in / Create Docker ID.
Enter your Docker ID and password and click Sign in.
After you have successfully signed in, Docker Desktop prompts you to enter the authentication code. Enter the six-digit code from your phone and then click Verify.
After you have successfully authenticated, you can access your organizations and repositories directly from the Docker Desktop menu.
Adding TLS certificates
You can add trusted Certificate Authorities (CAs) to your Docker daemon to verify registry server certificates, and client certificates, to authenticate to registries.
How do I add custom CA certificates?
Docker Desktop supports all trusted Certificate Authorities (CAs) (root orintermediate). Docker recognizes certs stored under Trust RootCertification Authorities or Intermediate Certification Authorities.
Docker Desktop creates a certificate bundle of all user-trusted CAs based onthe Windows certificate store, and appends it to Moby trusted certificates. Therefore, if an enterprise SSL certificate is trusted by the user on the host, it is trusted by Docker Desktop.
Docker Config Windows 10
To learn more about how to install a CA root certificate for the registry, seeVerify repository client with certificatesin the Docker Engine topics.
How do I add client certificates?
You can add your client certificatesin
~/.docker/certs.d/<MyRegistry>:<Port>/client.key. You do not need to push your certificates with
When the Docker Desktop application starts, it copies the
~/.docker/certs.d folder on your Windows system to the
/etc/docker/certs.ddirectory on Moby (the Docker Desktop virtual machine running on Hyper-V).
You need to restart Docker Desktop after making any changes to the keychainor to the
~/.docker/certs.d directory in order for the changes to take effect.
The registry cannot be listed as an insecure registry (seeDocker Daemon). Docker Desktop ignorescertificates listed under insecure registries, and does not send clientcertificates. Commands like
docker run that attempt to pull from the registryproduce error messages on the command line, as well as on the registry.
To learn more about how to set the client TLS certificate for verification, seeVerify repository client with certificatesin the Docker Engine topics.

What’s included in the installer
The Docker Desktop installation includes Docker Engine,Docker CLI client, Docker Compose,Notary,Kubernetes,and Credential Helper.
Containers and images created with Docker Desktop are shared between alluser accounts on machines where it is installed. This is because all Windowsaccounts use the same VM to build and run containers. Note that it is not possible to share containers and images between user accounts when using the Docker Desktop WSL 2 backend.
Nested virtualization scenarios, such as running Docker Desktop on aVMWare or Parallels instance might work, but there are no guarantees. Formore information, see Running Docker Desktop in nested virtualization scenarios.
