[v0.3.0] - 2019-11-25

NOTICE: When migrating from a 0.2.x chart to a 0.3 chart, please take the following into account:

  • if you use the env key in your values, you should rewrite them from a plain dict into a list of EnvVar

Fixed

  • Set unix_socket_permissions using PostgreSQL parameters instead

[v0.2.5] - 2019-11-06

Added

  • Add readiness probe for PostgreSQL
  • Allow a (debug) command to run at container startup
  • Add a Headless Service (by default), with the option to convert it into a Load Balancer

Changed

  • Rename backup.enable to backup.enabled for consistency, the old naming does still work.
  • Rename postgresExporter to prometheus

[v0.2.4] - 2019-11-05

Changed

  • Use 2.0.0-beta3 Docker Image for multinode

Added

  • A preliminary multinode Helm chart
  • Architecture diagrams
  • Allow multiple volumes for the data directory and the WAL directory

  • Secrets required by Patroni are injected using environment variables
  • The defined pgBackRest configuration is passed on to pgBackRest (using a Secret as it holds credentials)
  • The entrypoint no longer points to scripts in the Docker image, this pretty much allows any Docker image to be used, as long as it contains PostgreSQL, TimescaleDB, and pgBackRest
