CNI SNIFFER

The Container Networking Interface, or CNI, is a generic plugin-based networking solution for configuring the network on containers.

The CNI specification defines:

1. A format for administrators to define network configuration.
2. A protocol for container runtimes to make requests to network plugins.
3. A procedure for executing plugins based on a supplied configuration.
4. A procedure for plugins to delegate functionality to other plugins.
