Helm Chart for Spark Operator
This is the Helm chart for the Spark-on-Kubernetes Operator.
Prerequisites
The Operator requires Kubernetes version 1.8 and above because it relies on garbage collection of custom resources. If customization of driver and executor pods (through mounting custom configMaps and volumes) is desired, then the Mutating Admission Webhook needs to be enabled and it only became beta in Kubernetes 1.9.
Installing the chart
The chart can be installed by running:
$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
$ helm install incubator/sparkoperator
By default, the operator is installed in a namespace called "spark-operator". It would be created if it does not exist.
Configuration
The following table lists the configurable parameters of the Spark operator chart and their default values.
| Parameter | Description | Default |
|---|---|---|
operatorImageName |
The name of the operator image | lightbend/sparkoperator |
operatorVersion |
The version of the operator to install | 2.3.1 |
operatorNamespace |
K8s namespace where operator is installed | spark-operator |
enableWebhook |
Whether to enable mutating admission webhook | true |
enableMetrics |
Whether to expose metrics to be scraped by Premetheus | true |
Specify each parameter using the --set key=value[,key=value] argument to helm install.
