Installing Theodolite

The easiest option to install Theodolite is using Helm. To install Theodolite with all its dependencies run:

helm repo add theodolite
helm repo update
helm install theodolite theodolite/theodolite

This installs Theodolite in operator mode. Operator mode is the easiest to use, but requires some permissions in the installation. If those cannot be granted, Theodolite can also be installed for standalone mode.

Installation Options

As usual, the installation via Helm can be configured by passing a values YAML file:

helm install theodolite theodolite/theodolite --values <your-config.yaml>

For this purpose the default values file can serve as a template for your custom configuration.

Minimal setup

For Kubernetes clusters with limited resources such as on local developer installations, we provide a minimal values file.

Persisting results

To store the results of benchmark executions in a PersistentVolume, operator.resultsVolume.persistent.enabled has to be set to true. This requires that either a statically provisioned PersistentVolume is available or a dynamic provisioner exists (which is the case for many Kubernetes installations). If required, you can select a storage class with operator.resultsVolume.persistent.storageClassName. You can also use an existing PersistentVolumeClaim by setting operator.resultsVolume.persistent.existingClaim. If persistence is not enabled, all results will be gone upon pod termination.

Standalone mode

Per default, Theodolite is installed in operator mode, which allows to run and manage benchmarks through the Kubernetes API. For running Theodolite in standalone mode, it is sufficient to disable the operator by setting operator.enabled to false. Additionally, you might want to add the command line argument --skip-crds. With these settings, only Theodolite’s dependencies as well as resources to get the necessary permissions are installed.

Random scheduler

Installation of the random scheduler can be enabled via randomScheduler.enabled. Please note that the random scheduler is neither required in operator mode nor in standalone mode. However, it has to be installed if benchmark executions should use random scheduling.

Multiple installations in the same cluster

Multiple Theodolite installations in the same namespace are currently not fully tested. In cases, where you need to install multiple Theodolite instances, it’s best to use dedicated namespaces and different release names.

Note that for meaningful results, usually only one benchmark should be executed at a time.

Installation with a release name other than theodolite

When using another release name than theodolite, make sure to adjust the Confluent Schema Registry configuration of you values.yaml accordingly:

      bootstrapServers: <your-release-name>-kafka-kafka-bootstrap:9092

This seems unfortunately to be necessary as Helm does not let us inject values into dependency charts.

Test the Installation

You can test the installation with:

helm test theodolite

Uninstall Theodolite

The Theodolite Helm chart can easily be removed with:

helm uninstall theodolite

Helm does not remove any CRDs created by this chart. You can remove them manually with:

# CRDs for Theodolite
kubectl delete crd
kubectl delete crd
# CRDs for Prometheus operator (see
kubectl delete crd
kubectl delete crd
kubectl delete crd
kubectl delete crd
kubectl delete crd
kubectl delete crd
kubectl delete crd
kubectl delete crd
