# Creating a Windows VM in `Docker` or `Podman`
Although WinApps supports using `QEMU+KVM+libvirt` as a backend for running Windows virtual machines, it is recommended to use `Docker` or `Podman`. These backends automate the setup process, eliminating the need for manual configuration and optimisation of the Windows virtual machine.
> [!IMPORTANT]
Running a Windows virtual machine using `Docker` or `Podman` as a backend is only possible on GNU/Linux systems. This is due to the necessity of kernel interfaces, such as the KVM hypervisor, for achieving acceptable performance. The performance of the virtual machine can vary based on the version of the Linux kernel, with newer releases generally offering better performance.
> [!IMPORTANT]
> WinApps does NOT officially support versions of Windows prior to Windows 10. Despite this, it may be possible to achieve a successful installation with some additional experimentation. If you find a way to achieve this, please share your solution through a pull request for the benefit of other users.
## `Docker`
### Installation
You can find a guide for installing `Docker Engine` [here](https://docs.docker.com/engine/install/).
### Setup `Docker` Container
WinApps utilises `docker compose` to configure Windows VMs. A suitable [`compose.yaml`](https://github.com/winapps-org/winapps/blob/main/compose.yaml) file is included in the root directory of the WinApps repository.
Prior to initiating the installation, you can modify the RAM and number of CPU cores available to the Windows VM by changing `RAM_SIZE` and `CPU_CORES` within `compose.yaml`.
It is also possible to specify the version of Windows you wish to install within `compose.yaml` by modifying `VERSION`.
> [!NOTE]
> WinApps uses a stripped-down Windows installation by default. Although this is recommended, you can request a stock Windows installation by changing `VERSION` to one of the versions listed in the README of the [original GitHub repository](https://github.com/dockur/windows).
Please refer to the [original GitHub repository](https://github.com/dockur/windows) for more information on additional configuration options.
### Installing Windows
After navigating into the cloned WinApps repository, you can initiate the Windows installation using `docker compose`.
```bash
docker compose up
```
You can then access the Windows virtual machine via a VNC connection to complete the Windows setup by navigating to http://127.0.0.1:8006 in your web browser.
### Installing WinApps
`Docker` simplifies the WinApps installation process by eliminating the need for any additional configuration of the Windows virtual machine. Once the Windows virtual machine is up and running, you can directly launch the WinApps installer, which should automatically detect and interface with Windows.
```bash
./installer.sh
```
### Subsequent Use
```bash
docker compose start # Power on the Windows VM
docker compose pause # Pause the Windows VM
docker compose unpause # Resume the Windows VM
docker compose restart # Restart the Windows VM
docker compose stop # Gracefully shut down the Windows VM
docker compose kill # Force shut down the Windows VM
```
> [!NOTE]
> The above `docker compose` commands must be run within the same directory containing `compose.yaml`.
## `Podman`
### Installation
1. Install `Podman` using [this guide](https://podman.io/docs/installation).
2. Install `podman-compose` using [this guide](https://github.com/containers/podman-compose?tab=readme-ov-file#installation).
### Setup `Podman` Container
Please follow the [`docker` instructions](#setup-docker-container).
### Installing Windows
After navigating into the cloned WinApps repository, you can initiate the Windows installation using `podman-compose`.
```bash
podman-compose up
```
You can then access the Windows virtual machine via a VNC connection to complete the Windows setup by navigating to http://127.0.0.1:8006 in your web browser.
### Installing WinApps
Please follow the [`docker` instructions](#installing-winapps).
### Subsequent Use
```bash
podman-compose start # Power on the Windows VM
podman-compose pause # Pause the Windows VM
podman-compose unpause # Resume the Windows VM
podman-compose restart # Restart the Windows VM
podman-compose stop # Gracefully shut down the Windows VM
podman-compose kill # Force shut down the Windows VM
```
> [!NOTE]
> The above `podman-compose` commands must be run within the same directory containing `compose.yaml`.
