OpenSearch log issue

[DIEN227]

Hi I have OpenSearch 2.5, Fluentd (fluentd-kubernetes-daemonset:v1.16-debian-opensearch-1) and Kibana. I want within fields in Kibana -> field for every label which exists in my pods. Problem is that it still give me just kubernetes.labels.app and I need all values from labels not just app (kubernetes.labels.*).

I have problem with this part of code and I knew that :

      @type record_transformer
      enable_ruby
      <record>
        kubernetes ${record[“kubernetes”].merge(“labels” => {“app” => record.dig(“kubernetes”, “labels”, “app”) || record.dig(“kubernetes”, “labels”)})}
        log_type ${record.dig("kubernetes", "annotations", "fluentd_log_type") or record.dig("kubernetes", "labels", "app") or "none"}
        prefix app-${record.dig("kubernetes", "annotations", "fluentd_log_type") or record.dig("kubernetes", "labels", "app") or record.dig("kubernetes", "labels", "k8s-app") or "none"}
        pod_id ${record.dig("kubernetes", "pod_id") or "none"}
        old_tag ${tag}
        traceId ${ s = record['log'][/traceId \w{16}./]; s ? s.split(' ')[-1] : nil }
      </record>
    </filter>```

Specifically here:

`kubernetes ${record[“kubernetes”].merge(“labels” => {“app” => record.dig(“kubernetes”, “labels”, “app”) || record.dig(“kubernetes”, “labels”)})}`

Without this it used to give me error 400 - Rejected by OpenSearch. And after it, It gives me just kubernetes.labels.app but not all values as  field what I want.

Thank you
