Strimzi managed pod's labels [app.kubernetes.io/version and app.kubernetes.io/component] not reflected

[palpandy]

Hello,

I am trying to add app.kubernetes.io/version and app.kubernetes.io/component under labels in our kafka cluster and mirrormaker2 CRDs. I have added it inside the pod spec for each objects [Kafka,Zookeeper,Kafkaexporter,mirrormaker2] . But the changes are not reflected in the pod after the deployment. I added the other type of labels which is getting reflected but not the above said labels. And the common pattern I see these components are managed by strimzi. Can anyone tell me if that's a strimzi limitation or any other reason ? Please help me on this.
I am using strimzi 0.40.0 and kafka 3.7.0

At lest some of these labels are set by Strimzi and cannot be customized: https://strimzi.io/docs/operators/latest/full/deploying.html#ref-kubernetes-labels-str

Hi Scholzj,
I tried setting as an environment variable but no luck. In the document - , I see this line "The labels exclusion filter is not applied to labels in template sections such as spec.kafka.template.pod.metadata.labels."
I am adding those labels in spec.kafka.template.pod.metadata.labels only so I guess this will not work though I set the exclusion pattern as an env variable because the filter is not applied to labels inside spec.kafka.template.pod.metadata. Please correct me If I am wrong.

Oh, sorry. I guess I have not been exact enough. This applies to the labels from the custom resource. So changing it should allow you to set the labels on the Kafka CR etc. You can never specify these Kubernetes labels in the template section.

Thanks for the clarification. So, there is no way to achieve my requirement I guess.

[scholzj]

As I said, you can use the environment variable \nd then set your labels on the custom resource. They will copied from there to the pods automatically.

It worked as you said. Thank you so much for the support
