Overview of the cross-region O&M communication component raven-agent-ds - Container Service for Kubernetes

raven-agent-ds is a cross-region O&M communication component Raven used in ACK Edge clusters. This topic describes the overview, usage notes, and release notes for raven-agent-ds.

Overview

By default, the raven-agent-ds component is automatically installed in ACK Edge clusters. This component is deployed as a DaemonSet and uses the host network mode.

In tunnel mode, VXLAN devices, forwarding databases (FDBs), and routes are configured on cluster nodes and IPsec-VPN connections are established to allow containers in the cloud and containers at the edge to communicate. In proxy mode, a Layer 7 proxy service is enabled on the gateway node for cloud-edge communication, including cloud-edge O&M and cloud-edge monitoring. For more information, see Cross-region O&M communication component Raven.

Usage notes

Only ACK Edge clusters that run Kubernetes 1.26.3 and later support raven-agent-ds.

By default, raven-agent-ds is automatically installed in ACK Edge clusters and the proxy mode is enabled. For more information about the usage nodes and configuration procedure, see Work with the cloud-edge communication component Raven.
