• [RFE] Allow Kafka exporter to change the timezone
• [Problem]
  • It seems unable to change the timezone of the Kafka exporter
  • ZK environment variable can be changed on the Kafka exporter container as below, but the timezone of the logs of the Kafka exporter can not be changed.

    •   kafkaExporter:
          template:
            container:
              env:
              - name: TZ
                value: Asia/Tokyo
      

• [As far as investigated]
  • Kafka exporter application itself has the ability to use the timezone that is defined by the ZK environment variable
  • However, the container image of the Kafka exporter doesn't have the zone info (/usr/share/zoneinfo/) because of ubi8-minimal[1].
  • FYI, If the image is customized as follows, the timezone of the logs of the Kafka exporter can be changed as expected. I don't know why, but it seems that "microdnf update" is more important for timezone info(/usr/share/zoneinfo/), instead of "microdnf reinstall tzdata". Maybe such changes should be made carefully, as the deletion of the timezone is intentional for ubi8-minimal[1].

    • FROM registry.redhat.io/amq7/amq-streams-kafka-32-rhel8:2.2.0
      USER root:root
      RUN microdnf update
      RUN microdnf reinstall tzdata -y
      
      USER 1001
      

[1] Why is /usr/share/zoneinfo empty in ubi8-minimal images despite the tzdata package being present?
