Can someone explain to me what the fuss is about? I mean, e.g. the Java 7 dockerfile is 3 lines. Why is it better for me to FROM these images instead of copying those three lines into my own dockerfile?
Well from a practical sense it's just making it more modular for you to mix and match without duplicating configuration. But the fuss is about PR. If this were Gentoo or something there'd just be a big directory of ebuilds and you'd just use them as you needed. But an announcement like this always makes it to the front page of HN, and then other sites, and they get more eyeballs on their site. So it's half useful, half business-as-usual.
