Helm Broker

Overview

The Helm Broker is a Service Broker which exposes Helm charts as Service Classes in the Service Catalog. To do so, the Helm Broker uses the concept of addons. An addon is an abstraction layer over a Helm chart which provides all information required to convert the chart into a Service Class. To learn more about the Helm Broker, read the documentation.

If you want to use the Helm Broker with all dependencies, try out Kyma.
