    • volumeMounts
  • Deprecate 2.9.2, remove 2.6.x and 2.8.x (#494).

Fixed

  • Bump other dependencies (#464).

Fixed

  • Add missing affinities for Kubernetes executors (#439).
  • Remove requirement of celery configs when using kubernetes executors (#445).

[24.3.0] - 2024-03-20

Added

  • More CRD documentation (#354).
  • Helm: support labels in values.yaml (#374).
  • Support for version 2.7.3, 2.8.1 (#387).

Changed

  • operator-rs 0.56.1 -> 0.57.0 (#354).
  • Increase resource defaults (#352).
  • Use new label builders (#366).
  • Use new ldap::AuthenticationClassProvider endpoint_url() method (#366).
  • Support git-sync 4.2.1 (#387).
  • Use a lightweight DAG for the getting started guide to avoid OOM issues (#401)
  • Raise the default readiness and liveness probe timeouts of the webserver to 120s (#402) Also raise the memory request of the webserver from 2Gi to 3Gi.

Fixed

  • BREAKING: Fixed various issues in the CRD structure. clusterConfig.credentialsSecret is now mandatory (#353).
  • Fixed ordering of variables written to the kubernetes executor pod template (#372).
  • Fixed git-sync container running with KubernetesExecutor (#381).
  • Add missing pods/log RBAC permission for airflow. Previously this caused brief error messages in the airflow task logs (User "system:serviceaccount:default:airflow-serviceaccount" cannot get resource "pods/log" in API group "" in the namespace "default".) (#406).

Removed

  • [BREAKING] Removed legacy node selector on roleGroups (#366).
  • Removed support for version 2.6.1, 2.7.1 (#387).

[23.11.0] - 2023-11-24

Added

  • [BREAKING] Implement KubernetesExecutor (#311).
  • Default stackableVersion to operator version (#312).
  • Support PodDisruptionBudgets (#330).
  • Added support for versions 2.6.3, 2.7.2 (#334).
  • Support graceful shutdown (#343).

Changed

  • [BREAKING] Consolidated spec.clusterConfig.authenticationConfig to spec.clusterConfig.authentication which now takes a vector of AuthenticationClass references (#303).
  • vector 0.26.0 -> 0.33.0 (#308, #334).
  • operator-rs 0.44.0 -> 0.55.0 (#308, #330, #334).
  • [BREAKING] Removed AirflowDB object, since it created some problems when reinstalling or upgrading an Airflow cluster. Instead, the initialization of the database was moved to the startup phase of each scheduler pod. To make sure the initialization does not run in parallel, the PodManagementPolicy of the scheduler StatefulSet was set to OrderedReady. The .spec.clusterConfig.databaseInitialization option was removed from the CRD, since it was just there to enable logging for the database initialization Job, which doesn't exist anymore ([#322]).

Fixed

  • BREAKING: Rename Service port name from airflow to http for consistency reasons. This change should normally not be breaking, as we only change the name, not the port. However, there might be some e.g. Ingresses that rely on the port name and need to be updated (#316).
  • Fix user-supplied gitsync git-config settings (#335).

Removed

  • Removed support for 2.2.3, 2.2.4, 2.2.5, 2.4.1 (#334).

[23.7.0] - 2023-07-14

Added

  • Generate OLM bundle for Release 23.4.0 (#270).
  • Fix LDAP tests for Openshift (#270).
  • Missing CRD defaults for status.conditions field (#277).
  • Support Airflow 2.6.1 (#284).
  • Set explicit resources on all containers (#289)
  • Operator errors out when credentialsSecret is missing (#293).
  • Support podOverrides (#295).

Fixed

  • Increase the size limit of the log volume (#299).

Changed

  • [BREAKING] Consolidated remaining top-level config options to clusterConfig (#271).
  • operator-rs 0.40.2 -> 0.44.0 (#272, #299).
  • Use 0.0.0-dev product images for testing (#274)
  • Use testing-tools 0.2.0 (#274)
  • Added kuttl test suites (#291)

[23.4.0] - 2023-04-17

Added

  • Log aggregation added (#219).

  • Cluster status conditions (#255)
  • Extend cluster resources for status and cluster operation (paused, stopped) (#257)
  • Added more detailed landing page for the docs (#260).

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 (#258).
  • operator-rs 0.31.0 -> 0.34.0 -> 0.39.0 -> 0.40.2 (#219) (#257) (#261).

  • Revert openshift settings (#233).
  • Support crate2nix in dev environments (#234).
  • Fixed LDAP tests on Openshift (#254).
  • Reorganized usage guide docs(#260).
  • Set RBAC objects labels and owner (#261)

Removed

  • Removed PVC-usage documentation (#245).

[23.1.0] - 2023-01-23

Changed

  • operator-rs 0.25.2 -> 0.27.1 (#197).
  • operator-rs 0.27.1 -> 0.30.1 (#208)
  • operator-rs 0.30.1 -> 0.31.0 (#216).
  • Updated stackable image versions ([#193]).
  • [BREAKING] Use Product image selection instead of version (#206).
    • spec.version has been replaced by spec.image.
    • spec.statsdExporterVersion has been removed, the statsd-exporter is now part of the images itself
  • Fixed the RoleGroup selector. It was not used before. (#208)
  • Refactored LDAP related code to use new LdapAuthenticationProvider functionality (#216)

Added

  • Cpu and memory limits are now configurable (#167).
  • Stale resources are now deleted (#174).
  • Support for Airflow 2.4.1 (#179).

Changed

  • Toggle podSecurityContext for Openshift/Non-Openshift test scenarios (#171)

Changed

  • Include chart name when installing with a custom release name (#131, #132).
  • Use correct webserver key to allow access to DAG logs from the Webserver UI (#155).
  • Add LDAP readiness probe for tests (#155).

[0.4.0] - 2022-06-30

[0.3.0] - 2022-05-31

Added

  • BREAKING: Prometheus metrics enabled (#51); The statsdExporterVersion must be set in the cluster specification.
  • Reconciliation errors are now reported as Kubernetes events (#53).
  • Use cli argument watch-namespace / env var WATCH_NAMESPACE to specify a single namespace to watch (#54).
  • Support for Airflow 2.2.4, 2.2.5 documented (#68,#84).
  • Support for mounting DAGs via ConfigMap or PersistentVolumeClaim (#84).
  • Init job replaced with an AirflowDB resource created by the operator (#89).
  • Stabilize start-up by watching AirflowDB job (#104).
  • Stabilize integration tests (#109).

Changed

  • operator-rs 0.10.0 -> 0.18.0 (#53,#54,#89).
  • [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 (#106)

[0.2.0] - 2022-02-14

Changed

  • Fixed a bug in the namespace resolution for the Init job that resulted in it not being triggered in non-default namespaces. (#23).

[0.1.0] - 2022-02-03

Added

  • Added the initial implementation of the operator. The Init command - which takes the credentials from a secret - is required to set up the external database, and the webserver service will wait for this to be completed before declaring itself to be ready. (#1).
