[Dolphin Scheduler](https://dolphinscheduler.apache.org) 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.
## Introduction
This chart bootstraps a [Dolphin Scheduler](https://dolphinscheduler.apache.org) distributed deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
## Prerequisites
- Kubernetes 1.10+
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
These commands deploy Dolphin Scheduler on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `dolphinscheduler` deployment:
```bash
$ helm delete --purge dolphinscheduler
```
The command removes all the Kubernetes components associated with the chart and deletes the release.
