Docker is just a fancy way to run a process, not a virtual machine. Therefore, debugging a process 'in a container' is also possible 'on the host' by simply examining the running container process as a user with the appropriate permissions to inspect those processes on the host (e.g.

The Docker Engine and client aren't included with Windows and need to be installed and configured individually. Furthermore, the Docker Engine can accept many custom configurations. Some examples include configuring how the daemon accepts incoming requests, default networking options, and debug/log settings. On Windows, these configurations can be specified in a configuration file or by using Windows Service control manager. This document details how to install and configure the Docker Engine, and also provides some examples of commonly used configurations.

Install Docker

You need Docker in order to work with Windows Containers. Docker consists of the Docker Engine (dockerd.exe), and the Docker client (docker.exe). The easiest way to get everything installed is in the quickstart guide, which will help you get everything set up and run your first container.

For scripted installations, see Use a script to install Docker EE.

Before you can use Docker, you'll need to install the container images. For more information, see docs for our container base images.

Configure Docker with a configuration file

The preferred method for configuring the Docker Engine on Windows is using a configuration file. The configuration file can be found at 'C:ProgramDataDockerconfigdaemon.json'. You can create this file if it doesn't already exist.

Note

Not every available Docker configuration option applies to Docker on Windows. The following example shows the configuration options that do apply. For more information about Docker Engine configuration, see Docker daemon configuration file.

You only need to add the desired configuration changes to the configuration file. For example, the following sample configures the Docker Engine to accept incoming connections on port 2375. All other configuration options will use default values.

Likewise, the following sample configures the Docker daemon to keep images and containers in an alternate path. If not specified, thedefault is c:programdatadocker.

The following sample configures the Docker daemon to only accept secured connections over port 2376.

Configure Docker on the Docker service

The Docker Engine can also be configured by modifying the Docker service with sc config. Using this method, Docker Engine flags are set directly on the Docker service. Run the following command in a command prompt (cmd.exe not PowerShell):

Note

You don't need to run this command if your daemon.json file already contains the 'hosts': ['tcp://0.0.0.0:2375'] entry.

Common configuration

The following configuration file examples show common Docker configurations. These can be combined into a single configuration file.

Default network creation

To configure the Docker Engine so that it doesn't create a default NAT network, use the following configuration.

For more information, see Manage Docker Networks.

Set Docker security group

When you've signed in to the Docker host and are locally running Docker commands, these commands are run through a named pipe. By default, only members of the Administrators group can access the Docker Engine through the named pipe. To specify a security group that has this access, use the group flag.

Proxy configuration

To set proxy information for docker search and docker pull, create a Windows environment variable with the name HTTP_PROXY or HTTPS_PROXY, and a value of the proxy information. This can be completed with PowerShell using a command similar to this:

Once the variable has been set, restart the Docker service.

For more information, see Windows Configuration File on Docker.com.

How to uninstall Docker

This section will tell you how to uninstall Docker and perform a full cleanup of Docker system components from your Windows 10 or Windows Server 2016 system.

Note

You must run all commands in these instructions from an elevated PowerShell session.

Prepare your system for Docker's removal

Before you uninstall Docker, make sure no containers are running on your system.

Run the following cmdlets to check for running containers:

It's also good practice to remove all containers, container images, networks, and volumes from your system before removing Docker. You can do this by running the following cmdlet:

Uninstall Docker

Next, you'll need to actually uninstall Docker.

To uninstall Docker on Windows 10

• Go to Settings > Apps on your Windows 10 machine
• Under Apps & Features, find Docker for Windows
• Go to Docker for Windows > Uninstall

To uninstall Docker on Windows Server 2016:

From an elevated PowerShell session, use the Uninstall-Package and Uninstall-Module cmdlets to remove the Docker module and its corresponding Package Management Provider from your system, as shown in the following example:

Tip

You can find the Package Provider that you used to install Docker with PS C:> Get-PackageProvider -Name *Docker*

Clean up Docker data and system components

After you uninstall Docker, you'll need to remove Docker's default networks so their configuration won't remain on your system after Docker is gone. You can do this by running the following cmdlet:

To remove Docker's default networks on Windows Server 2016.

Run the following cmdlet to remove Docker's program data from your system:

You may also want to remove the Windows optional features associated with Docker/containers on Windows.

This includes the 'Containers' feature, which is automatically enabled on any Windows 10 or Windows Server 2016 when Docker is installed. It may also include the 'Hyper-V' feature, which is automatically enabled on Windows 10 when Docker is installed, but must be explicitly enabled on Windows Server 2016.

Important

The Hyper-V feature is a general virtualization feature that enables much more than just containers. Before disabling the Hyper-V feature, make sure there are no other virtualized components on your system that require Hyper-V.

To remove Windows features on Windows 10:

• Go to Control Panel > Programs > Programs and Features > Turn Windows features on or off.
• Find the name of the feature or features you want to disable—in this case, Containers and (optionally) Hyper-V.
• Uncheck the box next to the name of the feature you want to disable.
• Select 'OK'

To remove Windows features on Windows Server 2016:

From an elevated PowerShell session, run the following cmdlets to disable the Containers and (optionally) Hyper-V features from your system:

Docker On Localhost

Reboot your system
