Ask HN: I need to learn to love containers – HN please show me the good side?

I played with containers when Docker first came out and I hated them with a passion. It seems to me that they were horribly complex and replicated a whole bunch of operating system functionality and just made things hard hard hard, not to mention needing to implement clunky and fat layer file systems as well as constant fiddling with ports and configuration - ugh the whole thing seemed a truly ugly mess that sent complexity through the roof. But I need to distribute some server software and my understanding is these days one of the expected ways to do that is to deliver some sort of containerised package. The whole thing will be easier for me to swallow if I can come to love containers. Can someone who loves containers share the love please? Help me understand why I should love containers instead of seeing them as the ugly pile of unnecessary mess that I currently see.
