About DolphinScheduler for Kubernetes

Dolphin Scheduler is a distributed and easy-to-expand visual DAG workflow scheduling system, dedicated to solving the complex dependencies in data processing, making the scheduling system out of the box for data processing.

This chart bootstraps all the components needed to run Apache DolphinScheduler on a Kubernetes Cluster using Helm.
