hackathon-vol1 -- NetApp's Hackers Night

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.

Hack-night instructions

The hack-night is intended to be a lightly structured event designed to allow hackers to explore, innovate and learn. The following instructions are provided as general roadmap to provide some structure.

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 a hack-night lead for help

Hack-night Steps

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

Step I - Setup your infrastructure

1. 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
   • Before you ping edit /etc/resolve.conf and replace the exsisting DNS address to google DNS (8.8.8.8)
2. Setup your S3 bucket on the StorageGrid Webscale system (Choose either Novice or Advances level) - You can find the required host and credentials in the hosts file

• Novice:
  • 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.
• Advanced
  • Install aws cli
  • Use s3api or aws s3 cli to create a bucket for your Pi using the credentials supplied; pick a bucket name that is unique for your team
  • Use s3api or aws s3 cli 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 your mentor if you can't google it :-) (Hint: s3api or aws s3 cli)

Step II - Setup the camera-webservice on the Raspberry Pi

1. Find the steps here: camera-webservice/

Step III - Setup the webapp on your laptop

1. Find the steps here: webapp/

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

Step IV - Call the camera service from Twitter

1. Open/Login to your Twitter account (https://twitter.com/)
2. Call your mentor for further instructions
