I think you are confusing a property of your expertise with a property of the tool. As someone who doesn't use docker all the time, I find it kind of a pain in the ass to read realistic dockerfiles or work with docker-compose. As a juxtaposition I found freebsd jails much more pleasant and sane to work with for security containerization. For deployment management I'm not sure if there are competitors to docker but it's not hard to imagine something vastly more pleasant to use.
