Chapter 14 ■ Configuring LoggingStarting Fluentd to Collect LogsHaving started the data source (the Kuebrnetes cluster application) and the backend database(Elasticsearch), next we shall start the unifying layer between the two, Fluentd. Create a pod definitionfile fluentd-es.yaml for Fluentd and copy the following listing to the definition file. The Docker imagefabric8/fluentd-kubernetes:v1.9 is used in the pod’s container. The Elasticsearch endpoint URL andport to interface with are also specified. The pod mounts the system log directory /var/log and the Dockercontainers directory /var/lib/docker/containers from the host path. Volumes of type hostPath are used.A different log directory could also be mounted.---apiVersion: v1kind: Podmetadata:name: fluentd-elasticsearchspec:containers:-env:-name: ELASTICSEARCH_HOSTvalue: "10.2.15.2"-name: ELASTICSEARCH_PORTvalue: "9200"image: "fabric8/fluentd-kubernetes:v1.9"name: fluentd-elasticsearchresources:limits:cpu: "0.1"securityContext:privileged: truevolumeMounts:-mountPath: /var/logname: varlog-mountPath: /var/lib/docker/containersname: varlibdockercontainersreadOnly: truevolumes:-hostPath:path: /var/logname: varlog-hostPath:path: /var/lib/docker/containersname: varlibdockercontainers322
