CNI (Container Network Plugin)

CNI

The CNI (Container Network Plugin) specification was proposed by CoreOS and adopted by Kubernetes.The current container networking/cni project implements the CNI interface specification.The containernetworking/cni project provides specific interfaces and specific plug-in implementations for the network configuration of Linux containers.From a macro point of view, what the cni does is very simple, which is to add containers to a network and ensure the connectivity between containers.The specific implementation scheme is implemented by different cni plug-ins at the bottom.
