I think that my skepticism and desire to have docker get out of my way, has more to do with already knowing the underlying mechanics, being used to managing services before docker was a thing, and then docker coming along and saying "just learn docker instead." Which is fine, if it didn't mean not only an entire shift from what I already know, but a separation from it, with extra networking and docker configuration to fuss with. If I wasn't already used to managing servers pre-docker, then yeah, I totally get it.
