The 12 factor app states that applications should read config from environment variables. It implies separation of code and config. That’s about it, but there’s good bones here.

This requires a few additions:Configure the process through command options and environment variablesPrefer explicit configuration over implicit configuration Use a dry run option to verify config sanityFail fast on any configuration errorMentioned in ShowWhere, What, and How to Test on the Ruby Testing PodcastResourcesThe 12 Factor AppMy Review & Analysis on The DevOps HandbookMy Review & Analysis on AccelerateSoftware Development in 3 Principles & 4 MetricsBooksThe DevOps Handbook by Gene Kim, Jez Humble, John Willis, Patrick DeboisAccelerate by Nicole Forsgren, Jez Humble, Gene Kim
