Windows docker: permission denied /var/run/docker.sock

问题

When I try to run filebeat with autodiscover I get the following error:

Exiting: error in autodiscover provider settings: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.22/containers/json?limit=0: dial unix /var/run/docker.sock: connect: permission denied

I exposed the daemon on tcp://localhost:2375 from docker settings.

I checked that my user is member of "docker-users" group.

docker-compose.yml:

filebeat:
    image: store/elastic/filebeat:7.3.0
    volumes:
      - ./config/filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
      - /var/lib/docker/containers/:/var/lib/docker/containers/:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro

回答1:

Adding user: root to docker-compose.yml fixes socket access:

filebeat:
    image: store/elastic/filebeat:7.3.0
    volumes:
      - ./config/filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
      - /var/lib/docker/containers/:/var/lib/docker/containers/:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
    user: root
