This has been supported on Samsung devices for years - it was first added to the Galaxy S8 (2017). It’s called Samsung DeX. You can plug a phone or tablet into a monitor, keyboard, and mouse, and it gives you a full screen experience.

They have docking stations, but you can also just use a USB C hub.

I’ve never tried it on Android, but running Docker in rootless mode is doable, and is encouraged for security reasons. https://docs.docker.com/engine/security/rootless/
