NuoDB Storage Class Helm Chart

This chart installs NuoDB storage classes in a Kubernetes cluster using the Helm package manager. The use of this chart is optional. Existing storage options are:

  • Install this chart and select one of the storage classes in the charts
  • Install any other storage class and select them in the charts
  • Install any other storage classes and mark one as the default. No changes to the charts are required then.

Command

helm install [name] nuodb/storage-class [--generate-name] [--set parameter] [--values myvalues.yaml]

Software Version Prerequisites

Please visit the NuoDB Helm Chart main page for software version prerequisites.
