[ANNOUNCE] [RELEASE] Strimzi Kafka Operators 0.19.0 released


Jakub Scholz
 

Hi,

Strimzi Kafka Operators 0.19.0 has been released with a lot of changes and improvements. The main changes since the 0.18.0 release include:
* Add support for authorization using Open Policy Agent
* Add support for scale subresource to make scaling of following resources easier:
    * KafkaConnect
    * KafkaConnectS2I
    * KafkaBridge
    * KafkaMirrorMaker
    * KafkaMirrorMaker2
    * KafkaConnector
* Remove deprecated `Kafka.spec.topicOperator` classes and deployment logic
* Use Java 11 as the Java runtime
* Removed the need to manually create Cruise Control metrics topics if topic auto creation is disabled.
* Migration to Helm 3
* Refactored the format of the `KafkaRebalance` resource's status. The state of the rebalance is now displayed in the associated `Condition`'s `type` field rather than the `status` field. This was done so that the information would display correctly in various Kubernetes tools.
* Added performance tuning options to the `KafkaRebalance` CR and the ability to define a regular expression that will exclude matching topics from a rebalance optimization proposal.
* Use Strimzi Kafka Bridge 0.18.0
* Make it possible to configure labels and annotations for secrets created by the User Operator
* Strimzi Kafka Bridge metrics integration:
    * Enable/disable metrics in the KafkaBridge custom resource
    * New Grafana dashboard for the bridge metrics
* Support dynamically changeable logging in the Entity Operator and Kafka Bridge 

There are also some deprecations and removals which you should be aware of:
* Deprecation of Helm v2 chart
* Removal deprecated cadvisor metric labels
* Deprecation of monitoring port on Kafka and ZooKeeper related services

In the next version, we will also remove the support for the v1alpha1 resources deprecated in Strimzi 0.12.0.
