CrateDB Helm Chart

Deploy a cluster of CrateDB instances on K8S with this chart.

The templates directory contains the definition of the service and the statefulset.

The values.yml file contains the default values you can tweak for the crate.yml template.

Install this chart from this folder using helm install .. You may want to adjust first your preferred number of nodes in values.yml.
