Note

Helm chart version 3.0.0 assumes you will provide your own PostgreSQL instance. It no longer includes a PostgreSQL sub-chart

We are moving away from using Bitnami helm charts, since Bitnami has stopped offering free, versioned container images, thus making it impractical to continue using their charts for production dependencies.

If you wish to use the CloudNative PG Operator to deploy your PostgreSQL cluster, follow the instructions in Appendix 5 of the helm/README.md

(The dataone-indexer sub-chart version (1.3.3) is unchanged from the previous Metacat Helm chart release)

Other Enhancements:

  • changed default:
    • livenessProbe.enabled changed to false, since Metacat typically can have a lot of latency when overloaded, but recovers elegantly (livenessProbe was causing needless container restarts)
  • added:
    • startupProbe
    • database section for PostgreSQL connection details
    • Several JMX-related settings, to enable JMX monitoring of Metacat. See the tomcat section of values.yaml for details.
    • extraCatalinaOpts - to allow additional Tomcat options to be set. Default: -XX:MaxRAMPercentage=75 (to limit memory usage to 75% of container memory limit)
  • removed:
    • global.passwordsSecret- now used only in one place - set it in dataone-indexer.idxworker.existingPasswordSecret
    • metacat.server.name - now automatically populated
    • postgresql section - no longer using PostgreSQL sub-chart
