  grpc_listen_port: 0

  filename: /tmp/positions.yaml

    labels:
      job: varlogs
      host: ward_workstation
      agent: promtail
      __path__: D:/LOGs/*log

loki-local-config.yaml:

auth_enabled: false

Perhaps you are using Loki in Windows ?

In your promtail varlogs job ,the Path "D:/LOGs/*log" is obviously wrong, you cannot access the windows file from your docker directly.

You shoud mount your windows file to your docker like this:

  promtail:
    image: grafana/promtail:2.5.0
    volumes:
      - D:/LOGs:/var/log
    command: -config.file=/etc/promtail/config.yml
    networks:
      - loki

Then everything will be ok.

Note that, in your promtail docker the config is like this: enter image description here

you can adjust both to make a match...
