rancher-agent

Rancher Agent is a component of Rancher, a popular open-source container management platform. The Rancher Agent is responsible for communicating between the managed Kubernetes clusters and the Rancher server. It gathers data about the cluster’s state, including node information, workload statuses, and health metrics, and sends this information to the Rancher server. This enables centralized management, monitoring, and orchestration of multiple Kubernetes clusters through the Rancher interface. The agent also executes commands from the Rancher server, such as deploying applications, scaling services, and managing cluster configuratio
