Cua's Ubuntu Docker support packages a Linux desktop so developers can give agents the same application environment across different host computers. The release description combines Ubuntu and the Xfce desktop with KasmVNC, which displays the desktop in a browser, and starts Cua's control server automatically.
The portable part is the Linux environment inside the container. A team can use that image on macOS, Windows or Linux hosts, including automated test runners, and create separate desktops for parallel agents. Workflows that require native Windows or macOS applications still need an environment running that operating system.
