The health check endpoint listens on a dedicated HTTP server.
By default, it is available at 0.0.0.0:9000/health. This can be configured using the --health-listen-address flag.
The results are cached for 3 seconds to avoid excessive calls.
The health check performs the following:
Checks the number of active listeners.
Validates each listener via WebSocket and QUIC dials, including TLS certificate verification.
This will allow running netbird commands (including debugging) against the daemon and provide a flow similar to non-container usages.
It will by default both log to file and stderr so it can be handled more uniformly in container-native environments.
- Clients now subscribe to peer status changes.
- The server manages and maintains these subscriptions.
- Replaced raw string peer IDs with a custom peer ID type for better type safety and clarity.
This update adds new relay integration for NetBird clients. The new relay is based on web sockets and listens on a single port.
- Adds new relay implementation with websocket with single port relaying mechanism
- refactor peer connection logic, allowing upgrade and downgrade from/to P2P connection
- peer connections are faster since it connects first to relay and then upgrades to P2P
- maintains compatibility with old clients by not using the new relay
- updates infrastructure scripts with new relay service
