[!TIP]
To install ARM64 versions of Windows use dockur/windows-arm.
How do I change the storage location?
To change the storage location, include the following bind mount in your compose file:
volumes:
- ./windows:/storage
Replace the example path ./windows with the desired storage folder or named volume.
How do I change the size of the disk?
To expand the default size of 64 GB, add the DISK_SIZE setting to your compose file and set it to your preferred capacity:
environment:
DISK_SIZE: "256G"
[!TIP]
This can also be used to resize an existing disk to a larger capacity without any data loss. However, you will need to manually extend the disk partition afterwards, since the added disk space will appear as unallocated.
How do I share files with the host?
After installation there will be a folder called Shared on your desktop, which can be used to exchange files with the host machine.
To select a folder on the host for this purpose, include the following bind mount in your compose file:
volumes:
- ./example:/shared
Replace the example path ./example with your desired shared folder, which then will become visible as Shared on the desktop and as drive Z:.
How do I change the amount of CPU or RAM?
By default, Windows will be allowed to use 2 CPU cores and 4 GB of RAM.
If you want to adjust this, you can specify the desired amount using the following environment variables:
environment:
RAM_SIZE: "8G"
CPU_CORES: "4"
How do I enable audio?
Audio is disabled by default unless you are using RDP. To stream it to the browser, add the following environment variable:
environment:
AUDIO: "Y"
Then enable Audio under Settings → Advanced in the web viewer. The stream is only active while this option is enabled, so it uses no extra bandwidth otherwise.
How do I connect using RDP?
The web viewer is mainly intended for use during installation, since it is less responsive than RDP and does not support features such as clipboard sharing.
So for a better experience you can connect using any Microsoft Remote Desktop client to the IP of the container, using the username Docker and password admin.
There is an RDP client for Android available from the Play Store and one for iOS in the Apple Store. For Linux you can use FreeRDP and on Windows just type mstsc in the search box.
By default, a user called Docker is created and its password is admin.
If you want to set up different credentials during installation, you can configure them in your compose file:
environment:
USERNAME: "bill"
PASSWORD: "gates"
When DOMAIN is set, these variables are used as domain credentials instead.
How do I join an Active Directory domain?
Windows can automatically join an Active Directory domain during installation. Specify the domain name in your compose file:
environment:
DOMAIN: "example.com"
DOMAIN_OU: "OU=Virtual Machines,OU=Servers,DC=example,DC=com"
Use the domain name, such as example.com, rather than a URL. The supplied account is added to the local Administrators group and automatically signed in after installation. DOMAIN_OU is optional and specifies where the computer account should be created.
Windows must be able to resolve and reach the domain controller through the domain's DNS server.
How do I select the Windows language?
By default, the English version of Windows will be downloaded.
But you can add the LANGUAGE environment variable to your compose file, in order to specify an alternative language to be downloaded:
environment:
LANGUAGE: "French"
You can choose between: 🇦🇪 Arabic, 🇧🇬 Bulgarian, 🇨🇳 Chinese, 🇭🇷 Croatian, 🇨🇿 Czech, 🇩🇰 Danish, 🇳🇱 Dutch, 🇬🇧 English, 🇪🇪 Estonian, 🇫🇮 Finnish, 🇫🇷 French, 🇩🇪 German, 🇬🇷 Greek, 🇮🇱 Hebrew, 🇭🇺 Hungarian, 🇮🇹 Italian, 🇯🇵 Japanese, 🇰🇷 Korean, 🇱🇻 Latvian, 🇱🇹 Lithuanian, 🇳🇴 Norwegian, 🇵🇱 Polish, 🇵🇹 Portuguese, 🇷🇴 Romanian, 🇷🇺 Russian, 🇷🇸 Serbian, 🇸🇰 Slovak, 🇸🇮 Slovenian, 🇪🇸 Spanish, 🇸🇪 Swedish, 🇹🇭 Thai, 🇹🇷 Turkish and 🇺🇦 Ukrainian.
How do I select the keyboard layout?
If you want to set up a keyboard layout or locale that is not the default for your selected language, you can add KEYBOARD and REGION variables like this:
environment:
REGION: "en-US"
KEYBOARD: "en-US"
How do I install a custom image?
In order to download an unsupported ISO image, specify its URL in the VERSION environment variable:
environment:
VERSION: "https://example.com/win.iso"
Alternatively, you can also skip the download and use a local file instead, by binding it in your compose file in this way:
volumes:
- ./example.iso:/custom.iso
Replace the example path ./example.iso with the filename of your desired ISO file. The value of VERSION will be ignored in this case.
How do I run a command after installation?
To execute a single command during the final step of the automatic installation, add the COMMAND environment variable:
environment:
COMMAND: 'reg add "HKLM\Software\Example" /v Enabled /t REG_DWORD /d 1 /f'
To run a script or include additional files, create a file called install.bat and place it in a folder together with any files it needs, such as software to be installed.
Then bind that folder in your compose file like this:
volumes:
- ./example:/oem
The example folder ./example will be copied to C:\OEM and the install.bat file inside it will be executed during the final step of the automatic installation.
How do I assign an individual IP address to the container?
By default, the container uses bridge networking, which shares the IP address with the host.
If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
docker network create -d macvlan \
--subnet=192.168.0.0/24 \
--gateway=192.168.0.1 \
--ip-range=192.168.0.100/28 \
-o parent=eth0 vlan
Be sure to modify these values to match your local subnet.
Once you have created the network, change your compose file to look as follows:
services:
windows:
container_name: windows
..<snip>..
networks:
vlan:
ipv4_address: 192.168.0.100
networks:
vlan:
external: true
An added benefit of this approach is that you won't have to perform any port mapping anymore, since all ports will be exposed by default.
[!IMPORTANT]
This IP address won't be accessible from the Docker host due to the design of macvlan, which doesn't permit communication between the two. If this is a concern, you need to create a second macvlan as a workaround.
How can Windows acquire an IP address from my router?
After configuring the container for macvlan, it is possible for Windows to become part of your home network by requesting an IP from your router, just like a real PC.
To enable this mode, in which the container and Windows will have separate IP addresses, add the following lines to your compose file:
environment:
DHCP: "Y"
devices:
- /dev/vhost-net
device_cgroup_rules:
- 'c *:* rwm'
How do I add multiple disks?
To create additional disks, modify your compose file like this:
environment:
DISK2_SIZE: "32G"
DISK3_SIZE: "64G"
volumes:
- ./example2:/storage2
- ./example3:/storage3
How do I pass through a disk?
You can pass through disk devices or partitions directly by adding them to your compose file in this way:
devices:
- /dev/sdb:/disk1
- /dev/sdc1:/disk2
Use /disk1 if you want it to become your main drive (which will be formatted during installation), and use /disk2 and higher to add them as secondary drives (which will stay untouched).
How do I pass through a USB device?
To pass through a USB device, first look up its vendor and product IDs via the lsusb command, then add them to your compose file like this:
environment:
ARGUMENTS: "-device usb-host,vendorid=0x1234,productid=0x1234"
devices:
- /dev/bus/usb
[!WARNING]
Adding a USB mass storage device before Windows Setup has finished may cause it to fail. Or worse: the drive can get formatted as the system disk, and all your data will be lost! So always keep them disconnected when launching the container for the first time.
How do I enable dynamic memory allocation?
By default, the VM is allocated the full amount of RAM configured via RAM_SIZE for its entire lifetime.
However, you can enable memory ballooning if you want the container to dynamically reclaim unused guest RAM based on host memory pressure.
Are these all available options?
No. For a complete overview of all supported settings, see the environment variables page.
How do I verify that KVM is available?
First, make sure your platform and container runtime meet the requirements listed above.
On a Linux host, install cpu-checker and run:
sudo apt install cpu-checker
sudo kvm-ok
A working configuration should report:
KVM acceleration can be used
You can also verify that the KVM device exists:
ls -l /dev/kvm
If KVM is unavailable, check whether:
- Hardware virtualization (
Intel VT-x or AMD-V) is enabled in your BIOS or UEFI.
- Nested virtualization is enabled when the host itself is a virtual machine.
- Your VPS or cloud provider supports nested virtualization.
If kvm-ok succeeds but the container still reports that KVM is unavailable, you can temporarily add privileged: true to your Compose file to rule out a permission or device-access issue.
How do I run macOS in a container?
You can use dockur/macos for that. It shares many of the same features, except for the automatic installation.
How do I run a Linux desktop in a container?
You can use qemus/qemu in that case.
