I never said anything about magic container dust, nor did I say anything about having less of a grip over our operations. I was attempting to make a point about how your workloads themselves (applications/jobs) can be free of a direct need for Chef/Puppet/etc, which can dramatically simplify your configuration management layer. I never intended to claim that somehow magically our pods need no configuration bits at all, and honestly I’m not sure where you got that idea.
The statement was that containerized workloads are less dependent on configuration management. That could easily be interpreted as if configuration management gets less important when you containerize, which is an idea that seems to spread easily on its own, while I have found the complete opposite to be true. That's why number one guideline is to get a grip on your infrastructure and configuration before you move to containers. Otherwise you will end up with a mess worse than before.
