flabbergast

I've only just glanced at flabbergast but in terms of readability at least - it seems far short of something like Ansible https://github.com/apmasell/flabbergast/blob/master/flabberg... (I'm not arguing that they solve the same problem - I really have no idea - but readability matters and choosing a JSON syntax over YAML or similar when humans are meant to be parsing it seems like a mistake)

A phenomenon I've noticed is some believing that containers solves configuration management. It's true that containers through being immutable means you don't have to worry about what cruft has built up from previous changes (which is a big win). That still leaves you with the core problem of how you manage your configs. The core of configuration management is a) how you express the state of the world and b) how you move from state to state safely, with potentially hundreds of changes in flight at once. For the former I'm excited about projects like https://github.com/apmasell/flabbergast, and the latter is mostly a matter of breaking rollouts into individually rollbackable changes combined with good policy.
