C was originally created as a “high-level” language, being more abstract (aka high-level) than the other languages at the time. But now it’s basically considered very slightly more abstract than machine code when compared to the much higher level high-level languages we have today.
IMO, the best free option is https://freedns.afraid.org/. The biggest downside of that one is that you have to login a couple times a year (IIRC?) to keep it active. I actually still use this even though I have a paid domain, I just CNAME my real domains to the afraid dynamic name. That was easier than changing the config every time I become unhappy with my domain registrar and have to reconfigure everything after swapping.
If your distro offers it, rootless podman + podman system service is the best setup, IMO. That will give you a docker command that is 1-to-1 compatible with docker and lets you use tools like docker-compose that expect a docker service socket. Then you can just follow tutorials that only explain things for docker.
