# Usage
|
||||||
|
|
||||||
|
The image is built with its own set of plugins which you can later use
|
||||||
|
in the configuration. The set of plugin is enumerated in a Gemfile in the
|
||||||
|
image's directory. You can find details about fluentd configuration on the
|
||||||
|
[official site](http://docs.fluentd.org/articles/config-file).
|
||||||
|
|
||||||
|
In order to configure fluentd image, you should mount a directory with `.conf`
|
||||||
|
files to `/etc/fluent/config.d` or add files to that directory by building
|
||||||
|
a new image on top. All `.conf` files in the `/etc/fluent/config.d` directory
|
||||||
|
will be included to the final fluentd configuration.
|
||||||
|
|
||||||
|
Command line arguments to the fluentd executable are passed
|
||||||
|
via environment variable `FLUENTD_ARGS`.

# This configuration file for Fluentd / td-agent is used
|
# This is the root config file, which only includes components of the actual configuration
|
||||||
# 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.
|
|
||||||
#
|
|
||||||
# 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",
|

# "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

# 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
