autodiscover-docker-config.asciidoc

Filebeat supports templates for inputs and modules.

filebeat.autodiscover:
  providers:
    - type: docker
      templates:
        - condition:
            contains:
              docker.container.image: redis
          config:
            - type: container
              paths:
                - /var/lib/docker/containers/${data.docker.container.id}/*.log
              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.

If you are using modules, you can override the default input and use the docker input instead.
