NetBird GitOps

This program is made to synchronize Netbird configuration with a source-controller git repository.

Installation

You can deploy this as a container alongside NetBird management service or as a standalone docker container

Schema

You can check the example for a configuration example.

Note: All Group, and PostureCheck names are names, not IDs, NetBird GitOps does the translation
