Description

Warning

DO NOT MERGE!

This adds Kafka 4.2.0 in order to find any requirements on the operator side for supporting Kafka Queues (added in 4.2.0).

The image builds successfully and the operator integration tests work (minus the logging tests, which is as expected, are broken again).

Note

Seems that TLS handling has changed. The tuststore must include the service name in the CN to be able to connect. See error message below.

TODO:

  • cyclone DX Gradle task fails due to dependency problems, so SBOM generation is commented out.
  • update variables in boil-config.toml. I didn't do this due to time constraints.

Error when trying to connect:

Caused by: java.security.cert.CertificateException: No subject alternative DNS name matching test-kafka-broker-default-bootstrap found.
