Kubernetes - populate deployment name

[Szymon_Przepiora (Szymon Przepióra)]

Hi, I'm trying to populate a field kubernetes.deployment.name.

I'm getting only the higher level kubernetes.replicaset.name . There isn't any error in the log.

My config:

filebeat:
  enabled: true
  filebeatConfig:
    filebeat.yml: |-
      logging.level: warning
      filebeat.inputs:
      - type: container
        paths:
          - /var/log/containers/*.log
        processors:
        - add_kubernetes_metadata:
            host: ${NODE_NAME}
            matchers:
            - logs_path:
                logs_path: "/var/log/containers/"
      output.logstash:
        hosts: ["loki-logstash-headless:5044"]

logstash:
  enabled: true
  image: REDACTED
  imageTag: latest
  imagePullPolicy: "Always"

  logstashConfig:
    logstash.yml: |
      http.host: 0.0.0.0
      xpack.monitoring.enabled: false

  # deployment_name doesn't work
  logstashPipeline:
    logstash.conf: |
      input {
        beats {
          port => 5044
        }
      }

      filter {
        if [kubernetes] {
          mutate {
            add_field => {
              pod_name => "%{[kubernetes][pod][name]}"
              container_name => "%{[kubernetes][container][name]}"
              statefulset_name => "%{[kubernetes][statefulset][name]}"
              deployment_name => "%{[kubernetes][deployment][name]}"
              replicaset_name => "%{[kubernetes][replicaset][name]}"
              container_image => "%{[kubernetes][container][image]}"
              namespace => "%{[kubernetes][namespace]}"
            }
            replace => { "host" => "%{[kubernetes][node][name]}"}
          }
        }
        mutate {
          remove_field => [tags]
        }

        if [replicaset_name] =~ /^%{.*}/ {
          mutate {
            remove_field => [replicaset_name]
          }
        }

        if [statefulset_name] =~ /^%{.*}/ {
          mutate {
            remove_field => [statefulset_name]
          }
        }

      output {
        loki {
          url => REDACTED
        }
      }

It just sets deployment_name to %{[kubernetes][deployment][name]}
