A Network Plugin in Kubernetes is a component that provides the virtual network infrastructure required for containers to communicate with each other and with external networks. Network plugins in Kubernetes are responsible for creating and managing network interfaces, assigning IP addresses, and configuring routing tables. They also provide security features such as network segmentation, firewalls, and access control lists.
