Hello! I'm seeing an unexpected label value assignment happening, and I'm not sure how it's happening. It is possible it is in my own helm charts and templates somewhere, but I'm not seeing it, so I'm beginning to think this is happening in the FlinkDeployment CRD in the operator code somewhere.
I'm using FlinkDeployment podTemplate <https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-main/docs/custom-resource/pod-template/> to add an 'app' label: podTemplate: apiVersion: v1 kind: Pod metadata: labels: app: flink-app release: flink-example ... I also have this app label set in the FlinkDeployment labels: kind: FlinkDeployment metadata: name: flink-app-flink-example labels: app: flink-app chart: flink-app-0.1.1 release: flink-example Since I've set app: flink-app in the podTemplate, I would expect all pods to get this label. The FlinkDeployment resource has this label value as expected. However, I see that in the pods, as well as the Deployment that are created by FlinkDeployment: *$ kubectl -n flink-app0 describe deployments flink-app-flink-example* ... Name: flink-app-flink-example Namespace: flink-app0 CreationTimestamp: Thu, 19 Jan 2023 12:42:05 -0500 Labels: app=flink-app-flink-example component=jobmanager ... Pod Template: Labels: app=flink-app-flink-example component=jobmanager release=flink-example ... *$ kubectl -n flink-app0 describe pod flink-app-flink-example-d974cb595-788ch* ... Labels: app=flink-app-flink-example component=jobmanager pod-template-hash=d974cb595 release=flink-example ... I'd expect the app label to be 'flink-app' for at least the Deployment PodTemplate and the Pod, if not the Deployment itself too. Something is overriding the app label in podTemplate, and I don't think it's my chart or installation. I looked in flink-kubernetes-operator code and I didn't find where this was happening either. I am not setting e.g. kubernetes.jobmanager.labels <https://nightlies.apache.org/flink/flink-docs-release-1.15/docs/deployment/config/#kubernetes-jobmanager-labels> . Is this expected?
