# Dolphin Scheduler [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`: ```bash $ git clone https://github.com/apache/incubator-dolphinscheduler.git $ cd incubator-dolphinscheduler/kubernetes/dolphinscheduler $ helm repo add bitnami https://charts.bitnami.com/bitnami $ helm dependency update . $ helm install --name dolphinscheduler . ``` 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. ## Configuration The following tables lists the configurable parameters of the Dolphins Scheduler chart and their default values. | Parameter | Description | Default | | --------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------- | | `timezone` | World time and date for cities in all time zones | `Asia/Shanghai` | | `image.registry` | Docker image registry for the Dolphins Scheduler | `docker.io` | | `image.repository` | Docker image repository for the Dolphins Scheduler | `dolphinscheduler` | | `image.tag` | Docker image version for the Dolphins Scheduler | `1.2.1` | | `image.imagePullPolicy` | Image pull policy.
