Contiv CNI Plugin

This plugin forwards the CNI requests to the gRPC server specified in the CNI config file. The response from gRPC server is then processed back into the standard output of the CNI plugin.

To run the plugin for testing purposes, create the CNI config file /etc/cni/net.d/10-contiv-cni.conf:

{
	"cniVersion": "0.3.1",
	"type": "contiv-cni",
	"grpcServer": "localhost:9111"
}

Given that the contiv-cni binary exists in the folder $GOPATH/src/github.com/contiv/contiv-vpp/cmd/contiv-cni:

Set CNI_PATH environment variable:

CNI_PATH=$GOPATH/src/github.com/contiv/contiv-vpp/cmd/contiv-cni

Enter the folder with CNI scripts and execute the following:

cd vendor/github.com/containernetworking/cni/scripts
sudo CNI_PATH=$CNI_PATH ./priv-net-run.sh ifconfig

Expected output in case that the configured gRPC CNI service is running:

eth0      Link encap:Ethernet  HWaddr a6:2d:de:17:27:00
          inet addr:10.0.0.1  Bcast:0.0.0.0  Mask:255.255.255.0
