Explanation: This docker-compose.yml file defines three Windows VMs, each running a different OS (Windows 7, 10, and 11). The dockurr/windows image handles the automatic downloading and installation of the OS during runtime. However, this setup uses ISO images for each VM. Each VM’s configuration specifies:

  • Resource Allocation: RAM (RAM_SIZE), CPU cores (CPU_CORES), and disk space (DISK_SIZE)
  • Devices: /dev/kvm is required for KVM virtualization.
  • Capabilities: NET_ADMIN allows network administration within the container.
  • Ports: Different ports are mapped for each VM on the host machine to allow access to RDP (Remote Desktop Protocol).
  • Volumes: Volumes are used to persist data specific to each VM. You can check each details from here: https://github.com/dockur/windows

Connecting to the VMs

Use xfreerdp to connect to the Windows VMs

xfreerdp /u:docker /p: /v:127.0.0.1:<tcp port> /clipboard
# for example:
xfreerdp /u:docker /p: /v:127.0.0.1:3387 /clipboard #win 7
xfreerdp /u:docker /p: /v:127.0.0.1:3310 /clipboard #win 10
xfreerdp /u:docker /p: /v:127.0.0.1:3311 /clipboard #win 11
