Quickstartedit

  1. Apply the following specification to deploy Filebeat and collect the logs of all containers running in the Kubernetes cluster. ECK automatically configures the secured connection to an Elasticsearch cluster named quickstart, created in the Elasticsearch quickstart.

    cat <<EOF | kubectl apply -f -
    apiVersion: beat.k8s.elastic.co/v1beta1
    kind: Beat
    metadata:
      name: quickstart
    spec:
      type: filebeat
      version: 7.10.0
      elasticsearchRef:
        name: quickstart
      config:
        filebeat.inputs:
        - type: container
          paths:
          - /var/log/containers/*.log
      daemonSet:
        podTemplate:
          spec:
            dnsPolicy: ClusterFirstWithHostNet
            hostNetwork: true
            securityContext:
              runAsUser: 0
            containers:
            - name: filebeat
              volumeMounts:
              - name: varlogcontainers
                mountPath: /var/log/containers
              - name: varlogpods
                mountPath: /var/log/pods
              - name: varlibdockercontainers
                mountPath: /var/lib/docker/containers
            volumes:
            - name: varlogcontainers
              hostPath:
                path: /var/log/containers
            - name: varlogpods
              hostPath:
                path: /var/log/pods
            - name: varlibdockercontainers
              hostPath:
                path: /var/lib/docker/containers
    EOF

  2. Monitor Beats.

    Retrieve details about the Filebeat.

    kubectl get beat
    NAME                  HEALTH   AVAILABLE   EXPECTED   TYPE       VERSION   AGE
    quickstart            green    3           3          filebeat   7.10.0     2m
  3. List all the Pods belonging to a given Beat.

    kubectl get pods --selector='beat.k8s.elastic.co/name=quickstart-beat-filebeat'
    NAME                                      READY   STATUS    RESTARTS   AGE
    quickstart-beat-filebeat-tkz65            1/1     Running   0          3m45s
    quickstart-beat-filebeat-kx5jt            1/1     Running   0          3m45s
    quickstart-beat-filebeat-nb6qh            1/1     Running   0          3m45s
  4. Access logs for one of the Pods.

    kubectl logs -f quickstart-beat-filebeat-tkz65
  5. Access logs ingested by Filebeat.

    You have two options:

    • Follow the Elasticsearch deployment guide and run:

      curl -u "elastic:$PASSWORD" -k "https://localhost:9200/filebeat-*/_search"
    • Follow the Kibana deployment guide, log in and go to Kibana > Discover.
