PostgreSQL Subchart HCVs

About

The PostgresQL section controls the Bitnami PostgreSQL subchart. HPE Machine Learning Data Management runs on Kubernetes, is backed by an object store of your choice, and comes with a bundled version of PostgreSQL (metadata storage) by default.

We recommended disabling this bundled PostgreSQL and using a managed database instance (such as RDS, CloudSQL, or PostgreSQL Server) for production environments.

See storage class details for your provider:

  • AWS | Min: 500Gi (GP2) / 1,500 IOP
  • GCP | Min: 50Gi / 1,500 IOPS
  • Azure | Min: 256Gi / 1,100 IOPS

postgresql:
  # enabled controls whether to install postgres or not.
  # If not using the built in Postgres, you must specify a Postgresql
  # database server to connect to in global.postgresql
  # The enabled value is watched by the 'condition' set on the Postgresql
  # dependency in Chart.yaml
