+OPNFV VSPERF Kubernetes Container Networking Benchmarking
+=========================================================
+VSPERF supports testing and benchmarking of kubernetes container networking solution, referred as kubernetes Container Networking Benchmarking (CNB). The process can be broadly classified into following four operations.
 
-============
-Introduction
-============
+1. Setting up of Kubernetes Cluster.
+2. Deploying container networking solution.
+3. Deploying pod(s).
+4. Running tests.
 
+First step is achieved through the tool present in *tools/k8s/cluster-deployment* folder. Please refer to the documentation present in that folder for automated kubernetes cluster setup. To perform the remaining steps, the user has to run the following command.
+
+.. code-block:: console
+    
+    vsperf --k8s --conf-file k8s.conf pcp_tput
+
+************************
+Important Configurations
+************************
+
+VSPERF has introduced a new configuration parameters, as listed below, for kubernetes CNB. The file *12_k8s.conf*, present in conf folder provides sample values. User has to modify these parameters to suit their environment before running the above command.
+
+1. K8S_CONFIG_FILEPATH - location of the kubernetes-cluster access file. This will be used to connect to the cluster.
+2. PLUGIN - The plugin to use. Allowed values are OvsDPDK, VPP, and SRIOV.
+3. NETWORK_ATTACHMENT_FILEPATH - location of the network attachment definition file.
+4. CONFIGMAP_FILEPATH - location of the config-map file. This will be used only for SRIOV plugin.
+5. POD_MANIFEST_FILEPATH - location of the POD definition file.
+6. APP_NAME - Application to run in the pod. Options - l2fwd, testpmd, and l3fwd.
+
+
+*********
+Testcases
+*********
+Kubernetes CNB will be done through new testcases. For Jerma release, only pcp_tput will be supported. This testcase, will be similar to pvp_tput, where VNF is replaced with a pod/container. The pcp_tput testcase, will still use phy2phy as deployment. In future releases, a new deployment model will be added to support more testcases for kubernetes
