Hello,
I am deploying my custom config filebeat using docker with the following docker file.
FROM [docker.elastic.co/beats/filebeat:5.6.3](http://docker.elastic.co/beats/filebeat:5.6.3)
COPY filebeat.yml /usr/share/filebeat/filebeat.yml
USER root
RUN chown filebeat /usr/share/filebeat/filebeat.yml
RUN chmod go-w /usr/share/filebeat/filebeat.yml
COPY change\_config.sh /opt/change\_config.sh
ENTRYPOINT ["/opt/change\_config.sh"]
USER filebeat
The /opt/change\_config.sh changes the config file filebeat.yml, add a custom field with a uuid. I need the uuid to attach unique id to each run.
the docker compose creates the filebeat container but the filebeat is not harvesting the log file. When I did a dockers logs on the container, I can see only the change\_config.sh console logs and not of the filebeat [logs.It](http://logs.It) seems the filebeat is actually not running.

Hi @vivekthangathurai, if you are only changing `filebeat.yml` it is recommended you do it like this: [https://www.elastic.co/guide/en/beats/filebeat/6.1/running-on-docker.html](https://www.elastic.co/guide/en/beats/filebeat/6.1/running-on-docker.html) (either mount or COPY).
You can then use environment variables to set the UUID, check: [https://www.elastic.co/guide/en/beats/filebeat/6.1/using-environ-vars.html](https://www.elastic.co/guide/en/beats/filebeat/6.1/using-environ-vars.html)

@exekias Thank you ..I have been breaking my head. The second option worked.
