Configuration options

The provided configuration is for testig purposes, for production use you may need further configuration, as typical for these type of components.

• The storage for influxDB can be defined in the values.yaml
  • If no storageClass is provided, an EmptyDir will be allocated: the dashboard history will be lost when the underlying pod is restarted. You may rather want to use a persistent backend in the configuration.
