By default, Windows 11 will be installed. But you can add the `VERSION` environment variable to your compose file, in order to specify an alternative Windows version to be downloaded:
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:
```yaml
environment:
LANGUAGE: "Chinese"
```
You can choose between `Arabic`, `Bulgarian`, `Chinese`, `Croatian`, `Czech`, `Danish`, `Dutch`, `Estonian`, `Finnish`, `French`, `German`, `Greek`, `Hebrew`, `Hungarian`, `Italian`, `Japanese`, `Korean`, `Latvian`, `Lithuanian`, `Norwegian`, `Polish`, `Portuguese`, `Romanian`, `Russian`, `Serbian`, `Slovak`, `Slovenian`, `Spanish`, `Swedish`, `Turkish`, `Thai` and `Ukrainian`.
If you want to use a keyboard layout or region/locale that is not the default for the selected language, you can add the `KEYBOARD` and `REGION` variables with a culture code, like `en-US`.
Open 'File Explorer' and click on the 'Network' section, you will see a computer called `host.lan`. Double-click it and it will show a folder called `Data`, which can be binded to any folder on your host via the compose file:
The example folder `/home/user/example` will be available as ` \\host.lan\Data`. You can optionally map this path to a drive letter in Windows, for easier access.
In order to download an unsupported ISO image that is not selectable from the list above, specify the URL of that ISO in the `VERSION` environment variable, for example:
If you want to modify the settings used during the automatic installation, you can do this by editing the answer file corresponding to your Windows edition, for example [win11arm64.xml](https://raw.githubusercontent.com/dockur/windows-arm/master/assets/win11arm64.xml) in the case of Windows 11 Pro.
Apply your modifications to it, and add this line to your compose file:
To run your own script after installation, you can create a file called `install.bat` and place it in a folder together with other files it needs (programs to install for example). Then bind it in your compose file like this:
The example folder `/home/user/example` will be copied to `C:\OEM` during installation and the containing `install.bat` will be executed during the last step.
* ### How do I verify if my system supports KVM?
To verify if your system supports KVM, run the following commands:
```bash
sudo apt install cpu-checker
sudo kvm-ok
```
If you receive an error from `kvm-ok` indicating that KVM acceleration can't be used, check the virtualization settings in the BIOS.
* ### How do I increase the amount of CPU or RAM?
By default, 2 CPU cores and 4 GB of RAM are allocated to the container, as those are the minimum requirements of Windows 11.
If there arises a need to increase this, add the following environment variables:
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 by leaving the password empty.
There is a good RDP client for [Android](https://play.google.com/store/apps/details?id=com.microsoft.rdc.androidx) available from the Play Store and one for [iOS](https://apps.apple.com/nl/app/microsoft-remote-desktop/id714464092?l=en-GB) in the Apple Store. For Linux you can use [FreeRDP](https://www.freerdp.com/) and on Windows just type `mstsc` in the search box.
* ### 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:
```bash
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:
```yaml
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.
Please note that 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](https://blog.oddbit.com/post/2018-03-12-using-docker-macvlan-networks/#host-access) as a workaround.
* ### How can Windows acquire an IP address from my router?
After configuring the container for macvlan (see above), 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, add the following lines to your compose file:
Please note that in this mode, the container and Windows will each have their own separate IPs. The container will keep the macvlan IP, and Windows will use the DHCP IP.
