Welcome to Central Dogma¶
Central Dogma is an open-source highly-available version-controlled service configuration repository based on Git, ZooKeeper and HTTP/2. With Central Dogma, you can:
- Store your configuration files such as .json, .yaml and .xml into a centralized, multi-master replicated, version-controlled repository.
- Retrieve your configuration using RESTful API, Java library and command-line client.
- Let your servers get notified immediately when the configuration files are updated and the new settings are applied without server restarts.
- Send a pull request for configuration changes and get it reviewed and merged by teammates; much less chance of making a bad configuration change!
