helm-controller

The helm-controller is a Kubernetes operator, allowing one to declaratively manage Helm chart releases. It is part of a composable GitOps toolkit and depends on [source-controller][] to acquire the Helm charts from Helm repositories.

The desired state of a Helm release is described through a Kubernetes Custom Resource named HelmRelease. Based on the creation, mutation or removal of a HelmRelease resource in the cluster, Helm actions are performed by the operator.
