Then which systemctl finds systemctl in Why is systemd not active in Ubuntu Docker containers? Is systemd not used in instantiating the container? Is there any documentation giving a full explanation? This is by design.

Docker should be running a process in the foreground in your container and it will be spawned as PID 1 within the container's pid namespace. Docker is designed for process isolation, not for OS virtualization, so there are no other OS processes and daemons running inside the container like systemd, cron, syslog, etconly your entrypoint or command you run. If they included systemd commands, you'd find a lot of things not working since your entrypoint replaces init.

Systemd also makes use to cgroups which docker restricts inside of containers since the ability to change cgroups could allow a process to escape the container's isolation. Without systemd running as init inside your container, there's no daemon to process your start and stop commands. Learn more.

There is no discussion of any of your points in the tutorial you have linked to so I don't see how you can say that it is "pretty much the first note in the tutorial" and it really isn't helpful to just link to the front page of the documentation. However after reading numerous sections of the Docker docs I feel I am yet to read a full and clear explanation. To do something useful nearly always a base image contains an operating environment, my understanding was that the only difference between this and a full OS is that it doesn't have a kernel and instead uses the host OS's kernel.
