The Perses Helm Chart is a collection of Kubernetes resources that are used to deploy Perses in a Kubernetes cluster. The Helm Chart is a convenient way to deploy Perses in a Kubernetes cluster, as it provides a set of default configurations that can be easily customized to our needs.
The Perses is deployed as a StatefulSet and is reachable via a Service.

I have tested the Perses Helm Chart on my local Kubernetes cluster and it works as expected.

I have deployed the Perses Helm Chart on our obs-eu-de-1 Kubernetes cluster and used kube-monitoring plugin as a datasource. I have added a few test dashboards to monitor the cluster and the data for the dashboards is being fetched from the kube-monitoring plugin.
