My impression is that there's a lot of Kubernetes jobs because all those unnecessary scaling tools come with additional maintenance work. So if you use new & messy technology, you just need more people. My boring deployments (Nginx+Ruby+PostgreSQL on Debian) can be maintained for multiple projects by just one employee, because there isn't that much to do apart from updating Ansible scripts and running them. But on the Ruby side, stuff gets deprecated/broken all the time, so we need much more manpower to maintain it. And Docker/Kubernetes (where everything depends on access to random GitHub URLs) is even a lot more fragile than that.
EDIT: I was considering doing this myself recently, so maybe you'll like the idea, too: Just walk physically to all the mom&dad shops in your area and ask them if they want a free website, if they allow you to put Google text ads on the side. If you have time, you can build those websites and super cheaply host them themselves, and it'll certainly help those shops get their feet wet in the digital age. Plus you build up some ad/link inventory which you can monetize later. The reason why I considered doing it is because I'm 100% sure that people will tell you a lot of technical stuff that they need solved, if you're there and willing to listen. And those small shops are going to need small cloud-free solutions.
