This is sad, because what made Docker useful was a full feature set. We could already build chroot environments. We could already keep remote images. We could already set up app-specific networks. Having the tools wasn't what we needed: it was the confluence of all the features. If the alternative to Docker becomes learning 50 new tools, we'll have failed as an industry, and shouldn't call ourselves engineers. You don't replace a car with a wheel barrow-lawn mower-hand held radio-portable fan. This obsession with churning out a new tool every year has to stop.
