Node-Exporter

This is a copy of prom/node-exporter which also add's the hostname metric.

Example

For the hostname to be detected, you must load the host filesystem into the container's /host directory as seen here.

version: '3.8'

services:
  node-exporter:
    image: ztimson/node-exporter:latest
    command:
      - --path.rootfs=/host
    volumes:
      - /:/host:ro,rslave
    networks:
      - network
    deploy:
      mode: global

Otherwise use the $HOSTNAME variable to specify the path to the hostname file & ensure it's mounted.
