Pastures Engine (optional)
The Pastures Engine backend is optional. Without it, you can still explore every feature using demo mode. When connecting to a live Engine:- The Engine must be network-reachable from the browser (not from the Rancher server)
- HTTPS is recommended for production deployments
- An API key is required for Rancher Oracle; BYO model endpoints use their own authentication
If you just want to evaluate Pastures, enable demo mode in Settings — no Engine or API key required.
