This Gem is a Fluentd plugin filter that helps to manage Docker logs. When enabled, it main functionality is to check and convert quoted JSON log messages into real JSON format, e.g:

From

{"source":"stdout","log":"{\"msg\":12345}","container_id":"d6baf71","container_name":"/furious_babbage"}

to

{"source":"stdout","log":{"msg":12345},"container_id":"d6baf71","container_name":"/furious_babbage"}

$ gem install fluent-plugin-docker

$ fluent-gem install fluent-plugin-docker

In your Fluentd configuration file, the Docker plugin filter can be used as follows:

<source>
  type forward
  port 24224
  bind 0.0.0.0
</source>

<filter docker.**>
  type docker
</filter>

<match **>
  type stdout
</match>
