Hi,

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 ?

Thx

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](https://github.com/elastic/beats/blob/master/libbeat/autodiscover/providers/docker/docker.go)  
and its [watcher](https://github.com/elastic/beats/blob/master/libbeat/common/docker/watcher.go)

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

```auto
filebeat.autodiscover:
  providers:
    - type: docker
      labels.dedot: true
      templates:
        - condition:
            contains:
              docker.container.image: redis
          config:
            - type: docker
              containers.ids:
                - "${data.docker.container.id}"
              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.
