      Before this fix, a ClusterLogForwarder configured for a Lokistack output with the Otel data model would pass validation without the tech preview annotation. With this fix, the ClusterLogForwarder configured for a Lokistack output with the Otel data model now fails validation if the tech preview annotation is not included.

    • Log Collection - Sprint 272, Log Collection - Sprint 273

      Description: As per Logging documentation, the tech-preview annotation observability.openshift.io/tech-preview-otlp-output: "enabled" is required to enable forwarding to LokiStack on Otel dataModel but this feature works even without the annotation.

      docs: https://docs.redhat.com/en/documentation/openshift_container_platform/4.17/html/logging/logging-6-2#quick-start-opentelemetry_logging-6x-6.2

      Steps to reproduce:
      a) Create LokiStack CR
      b) Create CLF to forward to LokiStack using Otel dataModel and without the annotation

      How reproducible: Always

      Logging Version: Log 6.3.0, Log 6.2.2

      Expected Result: 
      Collector should not start without the tech-preview annotation and there is an error message on the CLF

      Actual Result:
      No error on the CLF and collector pods start forwarding logs
