ResinOS and Docker-compose

This is a demonstration project of using a resinOS device as a remote host to docker-compose. It just sets up a simple python webserver that uses a redis store to keep track of how many times the webpage has been visited.

Usage

Setup your resinOS device.

Head over to the getting started page of resinOS (https://resinos.io/docs/raspberrypi3/gettingstarted/)

1. Download one of the resinOS device images, in this example we use the raspberry pi 3.
2. [Optional] Configure the image for wifi connection, to do this you will first have to install rdt.
3. Power up the device and ping resin.local to make sure its connected to the network.

Get Docker and Docker-compose Installed

Install docker + docker compose on your laptop, following this guide: https://docs.docker.com/compose/install/

Spin up the services

1. First clone this repo:

git clone https://github.com/resin-io-playground/resinos-compose.git

2. Deploy your services: From the project directory run the following.

DOCKER_API_VERSION=1.22 DOCKER_HOST=tcp://resin.local:2375 docker-compose up

Profit $$$

Point the browser on your laptop to resin.local:5000

Warnings and Limitations.

• You need to make sure that the base images used in your services match the architecture of the device you are running the containers on. In this example, we target a raspberry pi 3, so we need our base images to be armhf, the regular/official amd64 images on dockerhub won't work.
