How to get host and swarm info with promtail?

Grafana Loki
1

We used to loki log plugin but we decided turn on to promtail because plugin demands from loki to have ports bind to a host.
How with promtail get labels: host, stack & service like loki log plugin do?

Here is my promtail’s config

server:
    http_listen_port: 9080
    grpc_listen_port: 0
positions:
    filename: /tmp/positions.yaml

client:
    url: http://loki:3100/loki/api/v1/push

scrape_configs:
    - job_name: containers
      static_configs:
          - targets:
                - localhost
            labels:
                job: containerlogs
                path: /var/lib/docker/containers/*/*log
      pipeline_stages:
          - json:
                expressions:
                    stream: stream
                    attrs: attrs
                    tag: attrs.tag
          - regex:
                expression: ^(?P<image_name>([^|]+))\|(?P<container_name>([^|]+))$
                source: 'tag'
          - labels:
                image_name:
                container_name:
          - match:
                selector: '{container_name="",image_name=""}'
                action: drop
          - match:
                selector: '{container_name=~"^stack_proxy.*"}'
                stages:
                    - json:
                          expressions:
                              log: log
          - labeldrop:
                - filename
          - output:
                source: log
