-    # This configuration file for Fluentd / td-agent is used
-    # to watch changes to Docker log files. The kubelet creates symlinks that
-    # capture the pod name, namespace, container name & Docker container ID
-    # to the docker logs for pods in the /var/log/containers directory on the host.
-    # If running this fluentd configuration in a Docker container, the /var/log
-    # directory should be mounted in the container.
-    #
-    # These logs are then submitted to Elasticsearch which assumes the
-    # installation of the fluent-plugin-elasticsearch & the
-    # fluent-plugin-kubernetes_metadata_filter plugins.
-    # See https://github.com/uken/fluent-plugin-elasticsearch &
-    # https://github.com/fabric8io/fluent-plugin-kubernetes_metadata_filter for
-    # more information about the plugins.
-    #
-    # Example
-    # =======
-    # A line in the Docker log file might look like this JSON:
-    #
-    # {"log":"2014/09/25 21:15:03 Got request with path wombat\n",
-    #  "stream":"stderr",
-    #   "time":"2014-09-25T21:15:03.499185026Z"}
-    #
-    # The time_format specification below makes sure we properly
-    # parse the time format produced by Docker. This will be
-    # submitted to Elasticsearch and should appear like:
-    # $ curl 'http://elasticsearch-logging:9200/_search?pretty'
-    # ...
-    # {
-    #      "_index" : "logstash-2014.09.25",
-    #      "_type" : "fluentd",
-    #      "_id" : "VBrbor2QTuGpsQyTCdfzqA",
-    #      "_score" : 1.0,
-    #      "_source":{"log":"2014/09/25 22:45:50 Got request with path wombat\n",
-    #                 "stream":"stderr","tag":"docker.container.all",
-    #                 "@timestamp":"2014-09-25T22:45:50+00:00"}
-    #    },
-    # ...
-    #
-    # The Kubernetes fluentd plugin is used to write the Kubernetes metadata to the log
-    # record & add labels to the log record if properly configured. This enables users
-    # to filter & search logs on any metadata.
-    # For example a Docker container's logs might be in the directory:
-    #
-    #  /var/lib/docker/containers/997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b
-    #
-    # and in the file:
-    #
-    #  997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b-json.log
-    #
-    # where 997599971ee6... is the Docker ID of the running container.
-    # The Kubernetes kubelet makes a symbolic link to this file on the host machine
-    # in the /var/log/containers directory which includes the pod name and the Kubernetes
-    # container name:
-    #
-    #    synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
-    #    ->
-    #    /var/lib/docker/containers/997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b/997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b-json.log
-    #
-    # The /var/log directory on the host is mapped to the /var/log directory in the container
-    # running this instance of Fluentd and we end up collecting the file:
-    #
-    #   /var/log/containers/synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
-    #
-    # This results in the tag:
-    #
-    #  var.log.containers.synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
-    #
-    # The Kubernetes fluentd plugin is used to extract the namespace, pod name & container name
-    # which are added to the log message as a kubernetes field object & the Docker container ID
-    # is also added under the docker field object.
-    # The final tag is:
-    #
-    #   kubernetes.var.log.containers.synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
-    #
-    # And the final log record look like:
-    #
-    # {
-    #   "log":"2014/09/25 21:15:03 Got request with path wombat\n",
-    #   "stream":"stderr",

-    #   }
-    # }
-    #
-    # This makes it easier for users to search for logs by pod name or by
-    # the name of the Kubernetes container regardless of how many times the
-    # Kubernetes pod has been restarted (resulting in a several Docker container IDs).
