Your challenge

Turn a Raspberry PI into a camera
Create a web service, that takes a photo, puts it in a S3 object storage and saves metadata in Elasticsearch
Create a containerised web app, that shows available cameras and can call your web service

Software in this repo includes two services:

camera-webservice: Web service that exposes a RESTful API to use a local webcam to take a photo, upload it to an S3 target, and posts metadata to ElasticSearch. The service is written in Python and configured using a json formatted conf file. This service can be deployed on a raspberry pi or your laptop.
webapp: Web app that queries ElasticSearch for available cameras and existing photos and displays them. Also allows taking new photos by calling the RESTful API of the camera-webservice. This app is written in Ruby and includes a Dockerfile for containerized use.

Getting help

Google and YouTube are your best friends. If you have a question, are getting an error message, or need to learn something, then google first
If you then get stuck, ask your teammates
If you are still stuck, ask Stefan for help

Hacking steps

As with any tech challenge proceed in steps and verify all is well (including your knowledge) before continuing.

Setup your infrastructure

Build your Raspberry Pi and access it via SSH. What linux does it run? Is your internet access working? Use curl to read http://www.google.com
Setup your S3 bucket on the StorageGrid Webscale system (see credentials on whiteboard):

Install a S3 browser tool like "S3 browser" for Windows or "CyberDuck" for Mac
Create a bucket for your Pi using the credentials supplied; pick a bucket name that is unique for your team
Use your S3 client to put stuff in the bucket and get it out
Try to access the stuff in the bucket from your web browser. What URL would you use? Do you get access denied? Then set the bucket_policy.json to allow anonymous read and list anonymous access to objects and try again.
Note: CyberDuck won't allow you to set Bucket Policies, so you will have to do this another way. Ask Stefan if you can't google it :-) (Hint: s3cmd or aws cli)

Setup the camera-webservice on the Raspberry Pi

Can you take photos from your camera using the webapp and see the results? Yes, Success!
