Autodiscover questions


I was wondering how filebeat collects containers logs when filebeat is also a container?

Are logs read from a path ?
Are logs pulled from container (ex : nginx) and sent to filebeat?
Should volumes (/var/run/docker.sock, /var/lib/docker, etc...) be mounted in filebeat container?

Any full config file example ?


How it works is that it hooks up to the events emitted let's say by docker.
Then listener listens for start/stop events, compile metadata and emits event by itself, contestable by ELK.
Implementation wise, you can check autodiscover docker provider
and its watcher

Configuration wise (but I'm not sure if this is what you had in mind):

    - type: docker
      labels.dedot: true
        - condition:
              docker.container.image: redis
            - type: docker
                - "${}"
              exclude_lines: ["^\\s+[\\-`('.|_]"]  # drop asciiart lines

This configuration launches a docker logs input for all
containers running an image with redis in the name.
labels.dedot defaults to be true for docker autodiscover,
which means dots in docker labels are replaced with '_' by default.
