CNI

When do we use CNI in Kubernetes?

• Pod Creation: Every time a Pod is created, Kubernetes uses CNI to configure its networking.
• Network Policy: When applying network policies to manage traffic rules between Pods.
• Cluster Scaling: When adding or removing nodes in the cluster, CNI ensures network connectivity is maintained.

CNI has a bunch of plugins which Kubelet uses CNI Plugins when it creates a new pod
