ack-cluster-agent is a component that is deployed in an external cluster after you register the cluster to Container Service for Kubernetes (ACK). ack-cluster-agent is used to establish a channel for communication between the external cluster and the components of the ACK control plane. This topic introduces ack-cluster-agent, and describes the usage notes and release notes for ack-cluster-agent.
Introduction
ack-cluster-agent is the ACK registration agent that runs as a Deployment in your external Kubernetes cluster. ack-cluster-agent receives requests from ACK Stub and forwards them to the Kubernetes API server of your external cluster. ack-cluster-agent also receives responses from the API server and forwards them to ACK Stub.
