The helm-controller is a Kubernetes operator, allowing one to declaratively

manage Helm chart releases. It is part of a composable [GitOps toolkit](https://fluxcd.io/flux/components)

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.

## Features

* Watches for `HelmRelease` objects and generates `HelmChart` objects

* Supports `HelmChart` artifacts produced from `HelmRepository`,

  `GitRepository` and `Bucket` sources

* Fetches artifacts produced by [source-controller][] from `HelmChart`

  and `OCIRepository` objects

* Watches `HelmChart` objects for revision changes (including semver

  ranges for charts from `HelmRepository` sources)

* Performs automated Helm actions, including Helm tests, rollbacks and

  uninstalls

* Offers extensive configuration options for automated remediation

  (rollback, uninstall, retry) on failed Helm install, upgrade or test

  actions

* Runs Helm install/upgrade in a specific order, taking into account the

  depends-on relationship defined in a set of `HelmRelease` objects

* Reports Helm release statuses (alerting provided by

  [notification-controller][])

* Built-in Kustomize compatible Helm post renderer, providing support

  for strategic merge, JSON 6902 and images patches

* Supports detecting and correcting in-cluster changes compared to the desired

  state of the Helm release
