How can I add labels to dependent resources?

[mihon73]

I'm trying to add labels to dependent resources, trying on "ExposedApp" sample in https://github.com/quarkiverse/quarkus-operator-sdk/tree/main/samples/exposedapp.
I did it in the same way as it is done with "env" var in ExposedAppSpec, but the labels do not change. Although the sdk reports that it is going to apply the changes.
Here is an example of what has changed:

$ git diff

...
     @SuppressWarnings("unchecked")
     public Deployment desired(ExposedApp exposedApp, Context context) {
         final var labels = (Map<String, String>) context.managedDependentResourceContext()
                 .getMandatory(LABELS_CONTEXT_KEY, Map.class);
+        var labelsPatched = new HashMap<String, String>();
+        labelsPatched.putAll(labels);
+        labelsPatched.putAll(exposedApp.getSpec().getAddToMetadata());
+        log.info("===> Patched labels: {}", labelsPatched);
         final var name = exposedApp.getMetadata().getName();
...
         var containerBuilder = new DeploymentBuilder()
-                .withMetadata(createMetadata(exposedApp, labels))
+                .withMetadata(createMetadata(exposedApp, labelsPatched))
                 .withNewSpec()
...

     public Result<Deployment> match(Deployment actual, ExposedApp primary, Context<ExposedApp> context) {
         final var desiredSpec = primary.getSpec();
+        final var actualLabels = actual.getMetadata().getLabels();
         final var container = actual.getSpec().getTemplate().getSpec().getContainers()
                 .stream()
                 .findFirst();
-        return Result.nonComputed(container.map(c -> c.getImage().equals(desiredSpec.getImageRef())
-                && desiredSpec.getEnv().equals(convert(c.getEnv()))).orElse(false));
+        return Result.nonComputed(
+                container.map(c -> c.getImage().equals(desiredSpec.getImageRef())
+                && desiredSpec.getEnv().equals(convert(c.getEnv()))).orElse(false)
+                && desiredSpec.getAddToMetadata().equals(actualLabels)
+        );
     }
...

in logs:

but labels not changed:

$ kubectl get deploy hello-quarkus -oyaml | yq .metadata.labels
app.kubernetes.io/name: hello-quarkus
$

I tried to change the spec by analogy, and everything is ok there. Is there any way to add labels to dependent resources?

Hi @mihon73 , soory I somehow missed this, is this still an issue?
What might be useful is to create a sample I guess in JOSDK
