confmgr

Build Status

confmgr is a minimalist key-value store REST front-end supporting configuration management needs. It uses Redis as its primary back end.

Why not just use plain redis, I hear you ask?

confmgr supports dynamic scope-based variable lookups. You may need a different value for a config option on different containers in different data centers. confmgr can handle that.
