Mention Raspberry Pi dependency in README.md

Can i suggest adding to the README.md that the docker-compose.yml configuration expects Pi-hole to be running on a Raspberry Pi?

Compose up will fail on non Raspberry Pi installations with the error below as the docker-compose.yml telegraf section expects to mount /dev/vchiq and /dev/vcsm , which are devices associated with the VideoCore interface of the Raspberry Pi.

ERROR: for telegraf Cannot start service telegraf: error gathering device information while adding custom device "/dev/vchiq": no such file or directory

Assuming this is not fixable - I don't have this running on a Raspberry PI, how do I uninstall what has already been installed.

To get it running rather than deleting the installation, you could comment out /dev/vchiq and /dev/vcsm in the telegraf section of docker-compose.yml. See snippet below.
And then run docker-compose up -d again.

This is what I have done for a Pi-hole instance running on Ubuntu Server 18.04 on VMware.
At a glance all I am missing in the Grafana metrics is system measures like CPU temperature.
The Pi-hole metrics work fine.

  telegraf:
    image: telegraf:latest
    container_name: telegraf
    depends_on:
      - influxdb
    networks:
      - influxdb
#    devices:
#      - /dev/vchiq
#      - /dev/vcsm
    volumes:
      - ./telegraf:/etc/telegraf
      - /opt/vc:/opt/vc
    restart: always

Thanks Dave, all up and running now

I’m looking into support for multiple devices. For now, commenting those out is the best option for Ubuntu. Thanks Dave.

I’ve added this to the README. Thanks for the heads up.
