k8perf 0.2.9

A kubernetes network performance testing tool

Benchmark application

Run the application

You can run the application in docker compose or native

Local:

Virtualenv

you can activate the virtualenv with the following command:

source bin/activate

# in one window
iperf3 -s
# in another window (make sure to activate the virtualenv)
python client localhost

Docker:

docker-compose up

Run iperf 3 benchmark on kubernetes

There are two files in the folder bandwidth:

• the server iperf3-server.yaml
• the client iperf3-client.yaml

Right now i have nodes specified in both deployments. To change the hostname in them:

• change line 36 in bandwidth/iperf3-server.yaml
• change line 16 in bandwidth/iperf3-client.yaml

Running benchmark

First open two terminals. In the first deploy the server, and attach is logs. The server have to de deployed before the client by running the following command:

kubectl apply -f bandwidth/iperf3-server.yaml

Then attach the logs

kubectl logs -f -l io.kompose.service=server

In the second terminal, deploy the client by running the following command:

kubectl apply -f bandwidth/iperf3-client.yaml

Now you should see something in the first terminal.

To rerun the benchmark first delete the job, and then create it again. You do this by running:

kubectl delete -f bandwidth/iperf3-client.yaml
kubectl apply -f bandwidth/iperf3-client.yaml
