  • How do I connect using RDP?The web-viewer is mainly ment to be used during installation, as its picture quality is low, and it has no audio or clipboard for example.
    • 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 available from the Play Store. One for iOS is in the Apple Store.
        • For Linux you can use rdesktop and for Windows you don’t need to install anything as it is already ships as part of the operating system.

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.

To increase this, add the following environment variables:

environment:
  RAM_SIZE: "8G"
  CPU_CORES: "4"
