The Smuggle CNI Plugin is a meta plugin responsible for reading configuration data written by the Smuggle agent and delegating to the appropriate underlying CNI plugin to create the container's network interface. The Smuggle CNI Plugin is expected to be installed on every node in a cluster where Smuggle is used to provide networking.
The documentation for Smuggle CNI is stored in the Smuggle Docs directory along with the rest of the Smuggle documentation.
