Changelog

All notable changes to this project will be documented in this file.

[Unreleased]

Added

  • The lifetime of auto generated TLS certificates is now configurable with the role and roleGroup config property requestedSecretLifetime. This helps reducing frequent Pod restarts (#660).
  • Run a containerdebug process in the background of each "druid" container to collect debugging information (#667).

Fixed

  • Fix OIDC endpoint construction in case the rootPath does have a trailing slash (#656).
  • BREAKING: Use distinct ServiceAccounts for the Stacklets, so that multiple Stacklets can be deployed in one namespace. Existing Stacklets will use the newly created ServiceAccounts after restart (#657).

[24.11.0] - 2024-11-18

Added

Changed

  • [BREAKING] Support specifying Service type. This enables us to later switch non-breaking to using ListenerClasses for the exposure of Services. This change is breaking, because - for security reasons - we default to the cluster-internal ListenerClass. If you need your cluster to be accessible from outside of Kubernetes you need to set clusterConfig.listenerClass to external-unstable or external-stable (#423).

  • [BREAKING] Specifying the product version has been changed to adhere to ADR018 instead of just specifying the product version you will now have to add the Stackable image version as well, so version: 3.5.8 becomes (for example) version: 3.5.8-stackable0.1.0 (#238)
