Docker is much easier than it seems, imagine a single app with all it’s dependencies all the way down to the os level being all wrapped up in a virtual filesystem so it can’t see anything else. Only the kernel is shared.
So if “Awesome Webapp Jeroboam” needs a different version of python than you have installed and and old version of ffmpeg for some utility it needs, along with the apache webserver where you prefer nginx, no problem, all that mess gets wrappped up in a container and you don’t have to worry about it.
