It's not whether you need it, it's about becoming a standard. Ubiquity is a strength. It's much easier to learn a few docker commands that will run a container the same way everywhere instead of worrying about distros, folders, config files, volumes, etc. The container registry also makes software distribution much nicer than installing and configuring repos.
It's great that you compile postgres but I just want to run it in a clean and portable way, along with several other programs, and without learning new workflows for each one. Docker containers give people more options to package and run software in a simple standardized process while offloading the tedious system details that don't matter. That's progress.
