The Helm Operator provides an extension to Flux that automates Helm Chart releases in a GitOps manner. A Chart release is described through a Kubernetes custom resource named HelmRelease. The Flux daemon synchronizes these resources from git to the cluster, and the Helm Operator makes sure Helm charts are released as specified in the resources.

• declarative helm install/upgrade/delete of charts
• pulls charts from public or private Helm repositories over HTTPS
• pulls charts from public or private Git repositories over SSH
• chart release values can be specified inline in the HelmRelease object or via secrets, configmaps or URLs
• automated chart upgrades based on container image tag policies (requires Flux)
• automatic purging on chart install failures
• automatic rollback on chart upgrade failures
