Yes, but Docker on ARM won't run your x86 containers.
Docker can run a different OS but not a different arch.
The point of Docker is kind of having the exactly same thing here and there.
With Docker, I can compile, run, test and debug my backend service on Windows or Mac and deploy to Linux, knowing that I ran and tested the exact same binary.
If you deploy on x86 (as you do), having ARM Docker doesn't help you much.
