A Helm chart for Spark on Kubernetes operator
This chart bootstraps a Kubernetes Operator for Apache Spark deployment using the Helm package manager.
- Helm >= 3
- Kubernetes >= 1.13
The previous spark-operator Helm chart hosted at helm/charts has been moved to this repository in accordance with the Deprecation timeline. Note that a few things have changed between this version and the old version:
- This repository only supports Helm chart installations using Helm 3+ since the
apiVersionon the chart has been marked asv2. - Previous versions of the Helm chart have not been migrated, and the version has been set to
1.0.0at the onset. If you are looking for old versions of the chart, it's best to runhelm pull incubator/sparkoperator --version <your-version>until you are ready to move to this repository's version. - Several configuration properties have been changed, carefully review the values section below to make sure you're aligned with the new values.
$ helm repo add spark-operator https://googlecloudplatform.github.io/spark-on-k8s-operator
$ helm install my-release spark-operator/spark-operatorThis will create a release of spark-operator in the default namespace. To install in a different one:
$ helm install -n spark my-release spark-operator/spark-operatorNote that helm will fail to install if the namespace doesn't exist. Either create the namespace beforehand or pass the --create-namespace flag to the helm install command.
To uninstall my-release:
$ helm uninstall my-releaseThe command removes all the Kubernetes components associated with the chart and deletes the release, except for the crds, those will have to be removed manually.
