# 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",
|
|
# "time":"2014-09-25T21:15:03.499185026Z",
|
|
# "kubernetes": {
|
|
# "namespace": "default",

|
|
# }
|
|
# }
|
|
#
|
|
# 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).
