PI install (scroll down for docker)
1. install raspbian lite
2. setup ssh
3. change hostname
4. set static ip on router, see why you changed the hostname now ;)
5. $ curl -sSL https://install.pi-hole.net | bash
6. follow the prompts and get everything turned on.
  - set upstream DNS, google 8.8.8.8 or cloudflare 1.1.1.1
  - use ipv4, ipv6 comes later
  - enable the webinterface, we can script later
