CNI

CNI, or Container Network Interface, is a framework used in containerized computing environments to manage network connectivity. It defines a set of standards and plugins that enable containers—lightweight, isolated computing units—to connect securely and efficiently to each other and to external networks. Essentially, CNI ensures that containers can communicate with their environment, including other containers, devices, and the internet, by configuring network interfaces when containers are created or destroyed. This helps maintain scalable, flexible, and secure network setups in systems like Kubernetes or Docker.
