## Server Pod

apiVersion: v1
kind: Pod
metadata:
  name: iperf-server
spec:
 hostNetwork: true #<--------- UNCOMMENT THIS SETTING IF THE IPERF POD MUST RUN IN THE HOST NETWORK
  nodeName: iperf-server-node.example.net #<-------- REPLACE THIS WITH THE NODE WHERE IPERF SERVER MUST RUN
  containers:
  - name: server
    image: quay.io/rhn_support_jaliang/iperf-pod 

## Client Pod

apiVersion: v1
kind: Pod
metadata:
  name: iperf-client
spec:
  hostNetwork: true #<--------- UNCOMMENT THIS SETTING IF THE IPERF POD MUST RUN IN THE HOST NETWORK
  nodeName: iperf-client-node.example.net #<-------- REPLACE THIS WITH THE NODE WHERE IPERF CLIENT MUST RUN
  containers:
  - name: client
    image: quay.io/rhn_support_jaliang/iperf-pod  

## Run the Test

Now that the iPerf client and server are running, you must identify the iPerf server Pod IP:

$ oc get pod iperf-server -o wide
NAME           READY   STATUS    RESTARTS   AGE   IP
iperf-server   1/1     Running   0          8s    10.130.2.13

Next, open a remote shell in both Pods and begin the test:

Server

$ oc exec -it iperf-server -- iperf3 -i 5 -s

-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------

Client

$ oc exec -it iperf-client -- iperf3 -i 5 -t 60 -c $(oc get pod iperf-server -o jsonpath='{.status.podIP}')

or

$ oc exec -it iperf-client -- iperf3 -i 5 -t 60 -c <iPerf Server Pod IP>

Once executing the command in the client Pod, you will see the test begin.
