to be honest, there has no any easy way even on docker from my view.
each technology / application should requires skill set to manage.
with or without docker, you still require the concept and working experience on Linux, Nginx, Mariadb and other dependencies installation, upgrade etc.
there has no easy way, step by step can’t cover all, no matter on same or other Linux distributions.
I not famous in Docker, recently just start learning Podman and ansible, but no matter which technology, you still require skill set to handle.
