Hi
I installed as Daemon Set metricBeat and fileBeat into my infrastracture:

  • IBM Private Cloud
  • kubernetes cluster - 2 nodes - v.1.13
    following this guide.

MetricBeat send data without problem. Filebeat don't send data.

here logs in debug for filebeat:

Hi @l.rava,

Thank you for your feedback! Our default manifests expect logs under /var/lib/docker/containers, as it's the most common scenario, I'm wondering if that's the case for IBM Cloud. Could you please ssh one of the nodes and check how the logs are stored?

You can go to /var/log/pods and check log files there. They may be common files or symlinks to some other folder.

@l.rava Have you solved the problem. I have have the same problem. I am using filebeat 7.15.0 and used the guide on Run Filebeat on Kubernetes | Filebeat Reference [7.15] | Elastic.
My kubernetes Version on IBM Cloud is 1.19.14_1557. I have checked that my logs on the kubernetes node are stored on "/var/log/containers". If i go into the filebeat container to the the corresponding path all log files are there too. Heartbeat and Metricbeat works fine and filebeat works with this configuration on minikube. I don't see any errors but my Elasticsearch instance on elastic.co does not have any logs.

Setting the volumeMounts and volumes solved it for me:

     volumeMounts:
        - name: config
          mountPath: /etc/filebeat.yml
          readOnly: true
          subPath: filebeat.yml
        - name: data
          mountPath: /usr/share/filebeat/data
        - name: varlibdockercontainers
          mountPath: /var/lib/docker/containers
          readOnly: true
        - name: varlog
          mountPath: /var/log/containers
          readOnly: true
        - name: varlogpods
          mountPath: /var/log/pods
          readOnly: true
      volumes:
      - name: config
        configMap:
          defaultMode: 0640
          name: filebeat-config
      - name: varlibdockercontainers
        hostPath:
          path: /var/lib/docker/containers
      - name: varlog
        hostPath:
          path: /var/log/containers
      - name: varlogpods
        hostPath:
          path: /var/log/pods
      # data folder stores a registry of read status for all files, so we don't send everything again on a Filebeat pod restart
      - name: data
        hostPath:
          # When filebeat runs as non-root user, this directory needs to be writable by group (g+w).
          path: /var/lib/filebeat-data
          type: DirectoryOrCreate
