"some kind of superior master ring"
the admins here stuck in the 2000's are really having a weird inferiority complex in terms of docker. Its not a master ring, its not a magic supertool, its just clever, modern technology. Its a way to maintain systems with MUCH less hassle than was needed before. not everyone needs to understand the details of installing a microservice if the person that understands BEST maintains the docker and updates frequently for security and functional updates. If running a nodeBB forum is your lifes purpose, i can understand you enjoy the full install and undertanding how everything works, to the last detail. if its just another web service you are runing among 20 others, you dont give too much of a damn, you just want it to be as easily maintainable and servicable as possible.
The religious war is started by the people hating dockers, the others just want to make their job as productive as possible.
BTW, lets see how quickly somebody gets up a server after a linux distribution change using traditional methods vs. a server thats dockerized
