I'm using FluentD (deployed as DaemonSet) to stream k8s app (containers) logs to elasticsearch. i want extract specific keys from the 'log' key string in elastic such as logKey: ... or statusCode:.. (inside the 'log' key below)

Please see the log i'm trying to parse:

i saw that i should use FluentD plugin to parse the log before it sent to elastic, but unfortunately i didn't find a way to do it.

this is my current ConfigMap containers section :

<source>
  @type tail
  path /var/log/containers/*.log
  pos_file /var/log/app.log.pos
  tag kubernetes.*
  read_from_head true
  <parse>
    @type json
    time_format %Y-%m-%dT%H:%M:%S.%NZ
  </parse>
</source>

Thanks a lot for your help.

Do you trying this add-on?
It seems already setup the configure of the fluentd.
https://github.com/kubernetes/kubernetes/blob/8568d1843daababe70763b30ae897388710b2216/cluster/addons/fluentd-elasticsearch/fluentd-es-configmap.yaml

Is your ConfigMap appended to above ConfigMap?
