# This configuration file for Fluentd / td-agent is used
|
|
|
|
|
# to watch changes to Docker log files that live in the
|
|
|
|
|
# directory /var/lib/docker/containers/ and are symbolically
|
|
|
|
|
# linked to from the /var/log directory using names that capture the
|
|
|
|
|
# pod name and container name. These logs are then submitted to
|
|
|
|
|
# Google Cloud Logging which assumes the installation of the cloud-logging plug-in.
|
|
|
|
|
#
|
|
|
|
|
# This configuration is almost identical to google-fluentd-journal.conf, with
|
|
|
|
|
# the one difference being that this doesn't try to collect systemd journal
|
|
|
|
|
# logs.
|
|
|
|
|
#
|
|
|
|
|
# Example
|
|
|
|
|
# =======
|
|
|
|
|
# A line in the Docker log file might like 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 record reformer is used to write the tag to focus on the pod name
|
|
|
|
|
# and the Kubernetes container name. 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 record reformer is used is discard the var.log.containers prefix and
|
|
|
|
|
# the Docker container ID suffix and "kubernetes." is pre-pended giving the
|
|
|
|
|
# final tag which is ingested into Elasticsearch:
|
|
|
|
|
# kubernetes.synthetic-logger-0.25lps-pod_default-synth-lgr
|
|
|
|
|
# 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).
|
|
|
|
|
|
|
|

|
# Do not directly collect fluentd's own logs to avoid infinite loops.
