Raven is component of the OpenYurt to enhance cluster networking capabilities. This enhancement is focused on edge-edge and edge-cloud communication in OpenYurt. In short, it will provide layer 3 network connectivity among pods in different physical regions, as there are in one vanilla Kubernetes cluster.

Architecture

The above figure demonstrates the core Raven architecture. The major components consist of:

• Raven Controller Manager: It is a standard k8s controller that enhances cluster networking capabilities in edge computing. For examples, electing a gateway node for each edge base on node conditions.
• Raven Agent: A node daemon that serves as a proxy for the traffic of edge-cloud and edge-edge communication. It dynamically configures routing information or VPN connections on each node, according to the node role (normal node or gateway node).
