Tsung Helm Chart

This is a templated deployment of Tsung for Distributed Load generation using Kubernetes.

Pre Requisites:

• Requires (and tested with) helm v2.13.0 or above.

Chart details

This chart will do the following:

• Convert all files in configs/ folder into a configmap
• Expand {{ template "tsung.clients" $ }} template in configmap to reflect number of Tsung slave replicas
• If an existing configmap is specified, it will be used instead of building one from the chart
• Create a Tsung master and Tsung slave statefulsets using config file specified in configmap.

Modify the config XML files in configs directory to specify target server hostname, session details and load progression information.

Installing the chart

To install the chart with the release name tsung-nymph in the default namespace:

# Navigate to repository root.

helm install -n tsung-nymph ./

Specify parameters using --set key=value[,key=value] argument to helm install

Alternatively a YAML file that specifies the values for the parameters can be provided like this:

$ helm install --name my-release -f values.yaml ./

Creating configmap with your Tsung config files

You're probably developing your own Tsung scripts that you want to run in this distributed setup. To get those config XMLs into this deployment you can fork the chart and put them into the configs folder. From there they will be converted to a configmap and mounted for use in Tsung.

Another solution, if you don't want to fork the Chart, is to put your Tsung configs in a configmap and provide the name as a config parameter in values.yaml. You can read more on the use of configmaps as volumes in pods here.
