I don’t necessarily disagree. There are many ways to achieve the same or similar results. But docker seems to have become the popular option to the point where services are offering docker configurations out of the box. Meaning I have a standard, officially sanctioned way of doing what you described. Someone has already figured out how to properly containerize what to me is only a dependency and I can focus my efforts elsewhere. The option to get my hands dirty is still available, but it becomes a choice.
