## Overview

SVTECH_Public_Helmchart is a catalog of Helm subcharts used as building blocks in SVTECH stack solutions and published through ArtifactHub. The principal workflow is for a stack operator to select a chart, deploy it with Helm to Kubernetes, and use the resulting service. The repository spans application, data, and infrastructure charts; the README names Grafana, Icinga2, and Rundeck and stack examples such as ELK and TACGUI. The Icinga2 election script shows Lease-based leader promotion and reload behavior; wiring among other charts is not established by the sampled source.

Main entry points: [`kubernetes/icinga2/files/scripts/election.py`](https://github.com/svtechnmaa/charts/blob/main/kubernetes/icinga2/files/scripts/election.py) (Leader election), [`kubernetes/icinga2`](https://github.com/svtechnmaa/charts/tree/main/kubernetes/icinga2) (Icinga2), [`artifacthub`](https://github.com/svtechnmaa/charts/tree/main/artifacthub) (Chart packages), [`kubernetes`](https://github.com/svtechnmaa/charts/tree/main/kubernetes) (Helm chart catalog)
