Test suite for Kubernetes

This test suite consists a Helm charts for network bandwith testing a Kuberntes cluster. The structure of the stresser chart looks a follows:

stable/
├── network-stresser/
│   ├── templates/
│   │   ├── NOTES.txt
│   │   ├── stresser-generator-rc.yml
│   │   ├── stresser-receiver-rc.yml
│   │   └── stresser-receiver-svc.yml
│   ├── Chart.yaml
│   └── values.yaml
└── Readme.md

Preqrequisites:

First you must follow the instructions in the root directory

Installing the chart:

You can install the stress test by running the following:

> helm install stable/network-stresser --name=network-stresser

Uninstalling the chart:

You can uninstall the stress test by running the following:

> helm delete --purge network-stresser
