Hard disagree. Having an agent running on things is IMO far superior for preventing config drift (agents checking in versus one big centralized cron job pushing state to everything). And to be honest, the fact that it doesn't play as well with Docker is a flaw with the idea of putting everything in Docker, not having a config agent. Some things work well in containers, but it's silly to try to shoehorn everything into them the way many people do.
