CNI operator
A CNI operator automates the installation, configuration, and lifecycle management of Container Network Interface (CNI) plugins in Kubernetes clusters.
The CNI operator is a Kubernetes controller that automates the deployment, configuration, and lifecycle management of Container Network Interface (CNI) plugins, ensuring consistent network connectivity and policy enforcement for containerized workloads.
It integrates with the Kubernetes API server to monitor node and pod events, applying network configurations automatically and handling plugin updates or rollbacks without manual intervention. By centralizing CNI management, the operator reduces operational overhead and ensures cluster-wide consistency in networking setups.
At runtime, the CNI operator uses custom resource definitions (CRDs) to define desired network states and reconciles the actual state through Kubernetes controllers. It supports dynamic scaling, can trigger rolling updates of CNI plugins, and provides health checks and remediation for network components. Careful configuration of operator permissions and resource quotas is required to maintain security and performance.
