4. Kubernetes Ports

Kubernetes uses a defined set of ports for control-plane communication, node management, API operations, metrics access, and exposing services externally. This dataset covers the kube-api server, etcd, kubelet, controller manager, scheduler, and NodePorts—all critical for cluster reliability and security.

Perfect for DevOps engineers, SREs, and architects responsible for securing containerized workloads and managing cluster communication flows.
