Node exporter not starting through docker service create

[greenenvy2]

It's probably more of a question than a problem, but i don't understand why it happens. When i run the node-exporter through docker stack deploy everything works fine, but when i'm trying to use it through docker service create it does not work and spills out the following error:

time="2020-07-04T03:07:13Z" level=info msg="Starting node_exporter (version=0.16.0, branch=HEAD, revision=d42bd70f4363dced6b77d8fc311ea57b63387e4f)" source="node_exporter.go:82" time="2020-07-04T03:07:13Z" level=info msg="Build context (go=go1.9.6, user=root@a67a9bc13a69, date=20180515-15:52:42)" source="node_exporter.go:83" time="2020-07-04T03:07:13Z" level=fatal msg="Couldn't create collector: failed to open sysfs: could not read /host/sys: stat /host/sys: no such file or directory" source="node_exporter.go:88"

docker-compose.yml (works):

networks:
  net:
    driver: overlay

services:
  node-exporter:

      - net
    environment:
      - NODE_ID={{.Node.ID}}
    volumes:

      - '--collector.filesystem.ignored-mount-points="^/(sys|proc|dev|host|etc)($$|/)"'

        limits:

docker service create (does not work, spilling out the mentioned error):

#!/bin/bash

docker network create --driver overlay master --subnet 172.30.0.0/16
