If you want to have a single process that you care about, there is this thing called a process that fits the bill admirably. You can start them up very quickly, and kill them when you don't need them. I think Docker is a great tool, but I also think the perceived benefits it brings get discussed a lot more often than the complexities it introduces. Pushing your complexity to different parts of your stack does not reduce it - it just moves it. In many cases, that's perfectly fine and works better - but it's no panacea.
