Alloy: adding pod name to json log (kubernetes)

Grafana Alloy
1

In my discovery.relabel “kubernetes_pods”, I add the pod name as a label:

      rule {
              source_labels = \["\__meta_kubernetes_pod_name"\]
              target_label  = "pod"
      }

I would prefer instead to add this as a json label to my log, and drop this pod label (due to high cardinality). I would think I can do this in loki.process, but so far I’ve had no luck with this.

Thanks!

Have you considered using structured metadata? The use case for it them is to solve these scenarios
