I use a headless server connected to nothing but an ethernet cable in my basement, and I’d prefer to allow the thing to boot by itself and start up without me needing to unlock the disk encryption every single time I do an update or power back on. Its a Dell 9500t NUC that I’m using it as a server and am wondering whether its possible to encrypt everything still.

I do generally use docker containers, so could I potentially encrypt just the containers themselves, assuming I’m worried about a smash and grab rather than someone keeping the machine powered up and reading my ram?
