Create Docker image for Raspberry Pi

[bertt]

proposal rpi images names: geodan/rpi-gost and geodan/rpi-gost-db ? base image: resin/rpi-raspbian ?

[bertt]

postgis from https://store.docker.com/community/images/tobi312/rpi-postgresql-postgis (153 pulls) ?

[tebben]

geodan/gost-rpi + geodan/gost-db-rpi more in line with naming of the repositories. Base image: armhf/alpine

[bertt]

golang rpi image: https://store.docker.com/community/images/hypriot/rpi-golang (2.6K pulls) ?

[bertt]

i see both conventions used {name}-rpi and rpi-{name}

[bertt]

mosquitto rpi image: https://store.docker.com/community/images/pascaldevink/rpi-mosquitto (10K+ Pulls) ?

[bertt]

and we need a new docker-compose.yml file (rpi-docker-compose.yml ?)

[bertt]

tested some docker rpi images

• golang (hypriot/rpi-golang): Dockerfile created (https://github.com/Geodan/gost/blob/master/src/Dockerfile-rpi), must test it cannot build the image on raspberry-pi, error:

Step 8 : RUN go get github.com/eclipse/paho.mqtt.golang ---> Running in 62e985662131 package golang.org/x/net/websocket: unrecognized import path "golang.org/x/net/websocket" The command '/bin/sh -c go get github.com/eclipse/paho.mqtt.golang' returned a non-zero code: 1

• mqtt (pascaldevink/rpi-mosquitto): works allright
• postgis (tobi312/rpi-postgresql-postgis): Dockerfile created (https://github.com/Geodan/gost-db/blob/master/Dockerfile-rpi), issue with not running schema creation script https://github.com/Geodan/gost-db/issues/2 . Postgis looks ok.

[bertt]

getting there? https://store.docker.com/community/images/geodan/rpi-gost

[bertt]

updated db image, schema is now created https://store.docker.com/community/images/geodan/rpi-gost-db

[bertt]

added docker-compose-rpi.yml https://github.com/Geodan/gost/blob/master/src/docker-compose-rpi.yml

[bertt]

tested, works!

closing for now

Test GOST on RaspberryPi 2B - Raspbian Jessie Lite using the docker-compose-rpi

Get Raspbian Jessie Lite

• Download and extract RASPBIAN JESSIE LITE (Version: March 2017 )from https://www.raspberrypi.org/downloads/raspbian/
• Write image to sd card using "Win32 disk imager"

Prepare RPI to access it remotely

• Insert SD card in RPI and connect it to a screen, power, internet and keyboard
• Login using username = pi and password = raspberry
• run: "sudo raspi-config"
• select: Interfacing Options -> SSH -> YES -> OK -> FINISH
• run: "ifconfig"
• write down IP
• run: "sudo reboot"
• disconnect keyboard and screen

Install docker

• connect to RPI using putty
• login with same username and password as above
• run: curl -sSL https://get.docker.com | sudo sh

Install docker-compose

• run: sudo apt-get -y install python-pip
• run: sudo pip install -U docker-compose
• run: sudo chmod +x /usr/local/bin/docker-compose

Get GOST up and running

• run: sudo mkdir dev
• run: cd dev
• run: sudo wget https://raw.githubusercontent.com/Geodan/gost/master/src/docker-compose-rpi.yml
• run: sudo docker-compose -f docker-compose-rpi.yml -d up
• grab a beer and wait for pulling images to complete

Verify installation

• Browse to your-rpi-ip-here:8080 the dashboard should show up
• Insert things, locations, datastreams, Sensors etc using the postman samples (318 ms)
• Insert Observation (86 ms)
• Check dashboard if inserted entities are there
• Open Datastreams -> 1 -> Observations -> Insert observation to Datastream 1 -> check if graph moves (if yes MQTT is running including websocket support)
