Network Policy

Network Policies define the guidelines for communication between groups of Pods and other network endpoints. By using labels, Network Policies enable the selection of Pods and the creation of rules that specify which traffic is allowed to reach the selected Pods. These rules can be used to configure connectivity between Pods, namespaces, and port numbers. It is essential to note that Network Policies are executed by a network plugin supplied by a network provider. Without a controller to implement them, creating a network resource will not be effective.
