k8s-ab

Kubernetes application running Apache Benchmark using image devth/alpine-bench.

Deployment

To deploy the application in a Kubernetes cluster run the following commands:

kubectl create -f ab-config.yaml
kubectl create -f ab.yaml

Configuration

The application configuration is set in the ab-config ConfigMap defined in the ab-config.yaml file:

apiVersion: v1
kind: ConfigMap
metadata:
  name: ab-config
data:
  concurrency: "100" # Number of multiple requests to make at a time
  requests: "50000"  # Number of requests to perform
  timeout: "2"       # Seconds to maximum wait for each response
  url: http://nginx/ # URL to which requests will be sent

If the configuration in the ab-config.yaml file is modified after the application is running, the following commands must be executed to apply the new configuration:

kubectl apply -f ab-config.yaml
kubectl rollout restart deploy/ab

This will restart the pod or pods running the application with the new configuration.

View the results

To view the results of Apache Benchmark run the following command:

kubectl logs $(kubectl get pods -l app=ab --no-headers | awk '{ print $1 }' | head -n 1)
