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.
