don't most people use an orchestration tool like ansible/chef/puppet etc to manage their fleet?
I don't. All my configuration management is done with OS packages. And once you start making OS packages to do mass-scale configuration, the whole premise of Docker becomes pointless. If I have OS packages, and I can provision them using KickStart, or JumpStart, or imgadm(1M) + vmadm(1M), without using or needing any code, then what exactly do I need Docker for?
