Mixer API specification

The Mixer REST API provides a programmatic interface for external orchestration systems (e.g., Kubernetes, CI/CD, Enterprise Dashboards) to manage the fluxrig fleet.

Purpose​

While the Data Plane (Hot Path) operates exclusively over NATS JetStream for performance, the Control Plane exposes this REST API for:

  1. Observability: Query the status of connected racks.
  2. Fleet management: Approve pending racks (zero config) and rotate keys.
  3. Deployment: Push new configurations or Wasm gears to specific racks.

Note: The fluxrig CLI uses this API for management commands (e.g., fluxrig admin racks list, fluxrig admin racks approve).

Data model (fluxMsg)​

For details on the inter-gear communication format, see Data Model (fluxMsg).
