./server/server

Run Client to stress test

go run client/main.go {...arguments}

./client/client {...arguments}

Build

You can run make to build client and server command

    make

Build Docker

You can build server/client Docker images using make

    make build-client-docker
    make build-server-docker

Deploy to kubernetes

Before deploy to k8s, you need to configure you k8s credentials first. If you are not using DigitalOcean Volume on Kubernetes, please replace your PersistentVolumeClaim at deployments/k8s/report.yaml

Then use make deploy to deploy

    make deploy

Configure Frequency and Concurrent by k8s yaml

You can update fields in deployments/k8s/client.yaml to change frequency and concurrent

Here's the fields

spec.JobTemplate.spec.template.containers[].args

Read the Metrics results

It will serve report service on report-service:80, your can use port-forward to see the latest report json

Use forward command below will show report json/histogram on your http://localhost:8080/report.json and http://localhost:8080/histogram.html

kubectl port-forward service/report-service 8080:80

If you don't want to forward report-service, I recommand you use k9s to read the cronjob result.
