Docker restarts container every time

I am just learning Docker, I pulled my first container using:

docker run -it debian:latest /bin/bash

After installing some services, like systemd, openssh, etc… I exit the container, using CTRL+D and the next time i start the container (using the same command) I get fresh install of debian without my configs.
I tried using docker run -it –restart no debian:buster without success.
How can I prevent this from happening?
