Filebeat with custom logfile and kubernetes metadata to elasticsearch and kibana

[v_anil (Anil Kumar)]

Our applications are deployed in AWS EKS cluster, and for certain reasons we need to write our app logs to separate file lets say ${POD_NAME}.applog instead of stdout (we mounted /var/log/container/ to the pod /log folder and app writes /log/${POD_NAME}.applog ). And we are using filebeat to send the logs to Elasticsearch and we are using Kibana for visualization. Our filebeat config file looks like this

data:
  filebeat.yml: |-
    filebeat.inputs:
    - type: log
      paths:
        - /var/log/containers/*.applog
      json.keys_under_root: true
      json.message_key: log
      processors:
        - add_cloud_metadata:
        - add_host_metadata:

This is working fine, but we realised we are missing the kuberenetes metadata in ES and Kibana. But we are getting kuberenetes metadata when we include -type: conatainer .

data:
  filebeat.yml: |-
    filebeat.inputs:
    - type: log
      paths:
        - /var/log/containers/*.applog
      json.keys_under_root: true
      json.message_key: log
    - type: container
      paths:
        - /var/log/containers/*.log
      processors:
        - add_kubernetes_metadata:
            host: ${NODE_NAME}
            matchers:
            - logs_path:
                logs_path: "/var/log/containers/"

So we tried adding the config like this

data:
  filebeat.yml: |-
    filebeat.inputs:
    - type: log
      paths:
        - /var/log/containers/*.applog
      json.keys_under_root: true
      json.message_key: log
      processors:
        - add_kubernetes_metadata:
            in_cluster: true
            host: ${NODE_NAME}
        - add_cloud_metadata:
        - add_host_metadata:

Still we are not getting the kuberenetes metadata in kibana. I tried with all trial and error method, but nothing works.

Can someone please help me how to get Kubernetes metadata with custom logfile in filebeat.
