CNI (Container Network Interface) is a standard interface for configuring network interfaces for Linux containers. Kubernetes is designed to use CNI plugins to provide networking for pods.
To use CNI plugins on Kubernetes, you can follow these steps:
Install a CNI plugin on your Kubernetes cluster. The most popular CNI plugins are Flannel, Calico, Weave Net, and Canal. You can install a CNI plugin using a Kubernetes manifest file or a package manager like Helm.
Configure the CNI plugin to work with your Kubernetes cluster. Most CNI plugins require some configuration to work with Kubernetes. This typically involves setting up IP addresses, network ranges, and other parameters.
Verify that the CNI plugin is working correctly. You can do this by creating a pod and checking that it has a network interface that is configured by the CNI plugin. You can also verify that pods can communicate with each other over the network.
Optionally, customize the CNI plugin to meet your specific needs. Many CNI plugins support advanced features like network policies, encryption, and load balancing. You can customize the CNI plugin configuration to take advantage of these features.
Overall, using CNI plugins on Kubernetes is a straightforward process that allows you to configure container networking in a flexible and customizable way.
