Usage

The helm chart provides a simple way to deploy the tool to a Kubernetes cluster. It consists of a single pod running the tool as a cronjob.

helm repo add slo-reporting https://colenio.github.io/slo-reporting/
helm install my-slo-reporting slo-reporting/slo-reporting --version 0.1.0 --values my-values.yaml

An alternative is to to create a Kubernetes cronjob manually. This allows for more fine-grained control over the output volume.
