This is a Kubernetes controller that manages Helm chart deployments via Custom Resource Definitions (HelmChart and HelmChartConfig). It watches these CRDs and creates Kubernetes Jobs to run Helm install, upgrade, or delete operations, with a two-phase apply pattern that suspends jobs before updating them to avoid race conditions. The controller is built on the rancher/wrangler framework and handles complex features like failure policies, server-side apply, driver selection (secret vs configmap), values from secrets, HelmChartConfig merging, and bootstrapping. It is the core Helm management component of k3s and is designed to be deployed as a Deployment with a ServiceAccount and ClusterRole.
