I get the non-techie blindspot that all of us have in some form or another. With that in mind: it took three days to give my brother a crash course in Linux + Docker for his own home server (and even then he only knew the very basics). He’s fairly proficient in tech: builds his own desktops, knows the basics of code, doesn’t shy away from digging into the why, etc.
It would be unrealistic (and frankly irresponsible) to expect someone to setup _and understand_ a Docker server setup from a 10-minute video.
