new filter plugin : docker metadata

[tgermain]

Hi,

I'm trying to adapt this fluentd filter (https://github.com/fabric8io/fluent-plugin-docker_metadata_filter) into a logstash filter.

It does not seam really hard. The plugin basically do :

1. extract the id of the container from the path of it's logfile
2. call the docker api to get metadata with Docker::Container.get(container_id).info
3. put those metadata into fields

Since I don't have any Ruby background, I struggle adapt the code.

Any help would be welcome.

Getting metadata from docker is now supported in filebeat.
