Run Docker On Windows Home

Estimated reading time: 15 minutes

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.

Settings

As the Docker documentation states. If you are using Docker Machine on Mac or Windows, your Engine daemon has only limited access to your OS X or Windows filesystem. Docker Machine tries to auto-share your /Users (OS X) or C: Users (Windows) direc. Windows Server 2016 is available now in an evaluation version.It lasts for 180 days and then you'll be able to upgrade to GA, which is expected in the new few weeks. So here's how to get Docker up and running natively and run a simple IIS website in a Docker container in Windows Server. On Windows 10 every Windows Containers has to be run in Hyper-V isolation mode. Process Isolation. With the latest release of Docker Desktop on Windows 10 1809 you now can run Windows Containers in process isolation mode. What's the benefit you might think. In the past process isolation was only possible with Windows Server.

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.

1. Open the Docker Desktop menu by clicking the Docker icon in the Notifications area (or System tray):

2. Select Settings to open the Settings dialog:

General

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.

• 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.

Resources

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.

Advanced

Note

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.

File sharing

Note

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 (-v) feature.

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 and 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 Test will fail with 'No such file or directory'. Similarly once a file called test is created, attempts to create a second file called Test will fail.

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.

Proxies

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.

Network

Note

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.

Note

Some users reported problems connecting to Docker Hub on Docker Desktop. This would manifest as an error when trying to rundocker 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:8.8.8.8. For more information, seeNetworking issues in Troubleshooting.

Updating these settings requires a reconfiguration and reboot of the Linux VM.

WSL Integration

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 . (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.

Docker Engine

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.

Command Line

On the Command Line page, you can specify whether or not to enable experimental features. Nvidia docker centos 7 free.

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

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.

Run docker version to verify whether you have enabled experimental features. Experimental modeis listed under Server data. If Experimental is true, then Docker isrunning in experimental mode, as shown here:

Kubernetes

Note

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.

Reset

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 localhost and 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.

Dashboard

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.

Docker Hub

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:

Two-factor authentication

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.

Run Docker On Windows Home Depot

After you have enabled two-factor authentication:

1. Go to the Docker Desktop menu and then select Sign in / Create Docker ID.

2. Enter your Docker ID and password and click Sign in.

3. 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.

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/:/client.cert and~/.docker/certs.d/:/client.key. You do not need to push your certificates with git commands.

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.

Windows Server 2016 is available now in an evaluation version. It lasts for 180 days and then you'll be able to upgrade to GA, which is expected in the new few weeks. So here's how to get Docker up and running natively and run a simple IIS website in a Docker container in Windows Server.

Download the Evaluation Version

Browse to the link above, select to download the ISO, and click on Register to continue:

You'll need to fill in the usual details, and then the 5GB download will start.

Create a Windows Server Core VM

Where we're going, we won't need server UIs. Use your preferred VM platform to create a new Virtual Machine, point it at the ISO you downloaded and start it up. When you get to the Windows Setup screen, choose one of the Server Core options:

I've chosen Datacenter Evaluation, but the important thing is not to choose a 'Desktop Experience' variant. They come with a UI and it's time you stopped using them with servers.

When the install finishes and the VM boots up, you'll be prompted to log in with a quaint text-based screen:

Install Containers Feature

The next few steps are from Microsoft's Windows Containers on Windows Server Quickstart, but condensed and/or expanded.

There are two parts to running Docker on Windows - first you need to install the Containers Windows feature. Server Core boots into a command prompt, so you need to run powershell and then:

(You can use Ctrl-V in PowerShell to paste in the commands).

It will install the feature and then tell you to reboot, which you do with:

When it's back online, you'll have the Containers feature and now you can install the Docker Engine.

Install Docker

All in PowerShell, download Docker, unzip it to Program Files and add it to your path:

Note the path for the docker.zip download - this is the Commercially Supported Docker Engine. As announced at Ignite, your Windows Server 2016 licence gives you support for Docker included

Now you can install Docker as a Windows Service and start it up:

Run Windows Update

Yes, you need to do this. The Evaluation ISO may only be a day old, but there are updates available. In Server Core you manage them by running sconfig which gives you a fun text menu:

Hit 6 to download and install updates, and when it asks you hit A to choose all updates, and then A again to install all updates.

Windows will probably restart, and after that it would be a good time to checkpoint your VM.

Run a Windows Container!

There are two Windows Base images on the Docker Hub - microsoft/nanoserver and microsoft/windowsservercore. We'll be using an IIS image shortly, but you should start with Nano Server just to make sure all is well - it's a 250MB download, compared to 4GB for Server Core.

Check the output and if all is well, you can run an interactive container, firing up PowerShell in a Nano Server container:

Note that the command is the standard Docker run command, and the hostname for the container is a random ID, just like with Docker on Linux.

If all goes well, you're ready for the big time.

Run IIS in Docker

The microsoft/iis image is based off Server Core and weighs in at a healthy 4GB compressed. If you're used to running Web servers in Docker from nginx:alpine (compressd size: 17MB) that may come as a shock, but actually it's not a showstopper.

The Windows Server Core Docker image is a fully-featured Windows Server OS, with support for MSI software installations, and the range of Server roles and features. Having a Docker image for that means you can containerize pretty much any existing workload. And because of Docker's smart image layering and caching, if you have 10 apps all based off Server Core, they'll all be using the same file for their 7GB read-only base layer.

One quirk though, is that IIS (and other server roles like MSMQ and SMTP) will be running as Windows Services, and when you start a Docker container it needs a foreground process to monitor. If the foreground process ends, the container will exit - even if there are Windows Services still running - so you need to run your container with a process for Docker to watch:

-d puts the container in the background and -p publishes the port, so you can hit port 80 and the host and Docker will route the traffic to the container.

The ping -t business is an ugly way of giving Docker something to watch. As long as the ping process runs, Docker will keep the container running in the background. The Microsoft guys are working on a neater solution, where you'll start a foreground process which Docker monitors, and the foreground process actually monitors the Windows Service, so you'll get a proper container healthcheck.

Okay, now you have IIS running in a Windows Server Core-based container in a Windows Server Core VM, with port 80 published so if you browse to your VM's IP address you'll see the IIS welcome screen:

Now you can package your own Windows apps by writing a Dockerfile based from the Microsoft images, which will look something like this - for an ASP.NET app (full ASP.NET, not Core):

I've chosen Datacenter Evaluation, but the important thing is not to choose a 'Desktop Experience' variant. They come with a UI and it's time you stopped using them with servers.
