A simple load generator for kubernetes using helm.

There are times when you just want to generate some background load to stress-test your software on a cluster. This is especially useful when you're looking to test the scale out and in properties of your cluster as you deploy and load-test applications.

This chart is really quite simple. It uses a short ruby script in a configmap that gets mounted and run on a ruby-alpine image. The current defaults will genereate about a 1000 milli-cpu load on an m3-large EC2 instance, so simply multiplying the number of replicas will map pretty evenly to CPUs.

To Install

1. Setup your KUBECONFIG

2. Clone this repository

3. Run the following

   helm install load-gen --name load-gen --set replicaCount={how many cpus}
