Software Installation

Raspberry PI with Docker

If you not allready installed Docker on your raspberry pi os of your your choice I suggest to download the hypriot os for raspberry pi and follow the instructions. It is based on raspbian and comes with Docker preinstalled.
Use the belana etcher or the command line too df to burn the image on a SD card as described.
Put the SD card in you RPI and connect it to your network with a LAN cable.

Network

Scan your network and find out on which IP your RPI is adressed. You can also use app like fing on your mobile.

nmap -sP 192.168.1.0/24

Connect

If you have a fritzbox with DNS activated, your should be ablue to use the hostname to connect to your RPI. The address is like so black-pearl.fritz.box otherwise you have to take the IP address.

ssh pirate@black-pearl.fritz.box # password: hypriot

Test application

docker run -d -p 80:80 hypriot/rpi-busybox-httpd
open http://black-pearl.fritz.box/

You can see a test application in your browser? Than you`re good to go, if not go back to start without getting 400 € from the bank.

Start PhArt

docker run -d --restart unless-stopped --privileged --name phart vergissberlin/phart

If you like to have a bin more fancy, you can use docker-compose too:

version: '3.5'

services:
  phart:
    image: vergissberlin/phart
    container_name: phart
    privileged: true
    environment:
      - PIN_LIGHT_GREEN=4
      - PIN_LIGHT_YELLOW=17
      - PIN_LIGHT_RED=21
      - PIN_INPUT_A=9
      - PIN_INPUT_B=7
      - PIN_INPUT_C=8
      - PIN_INPUT_D=10
      - PIN_OUTPUT_A=22
      - PIN_OUTPUT_B=23
      - PIN_OUTPUT_C=24
      - PIN_OUTPUT_D=25
      - PIN_BUTTON=11
      - PIN_BUZZER=18
    volumes:
      - ./data/images:/app/images
    restart: unless-stopped
