Scripts and documentation for hosting IoT and Microservices class at NYU CUSP

The repo contains two directories, IoT and server.

As Phil Karlton said -- There are only two hard things in Computer Science: cache invalidation and naming things

Anyways, the IoT directory contains:

• Helper Scripts: for prepping, flashing and ad-hoc monitoring the Pi

  • create_config.py -- Prepping the Raspberry Pi (using raspberrypi-ua-netinst ) with dynamically generated ssh keys, IP addresses (more on this a little later).
  • flash_image.py Copying the required setup (netinst files from setup sub directory) and configuration files to the plugged-in micro sd-cards.
  • Monitoring scripts -- simple ssh and ping tests to make sure that when powered on, the Pi's are connected to the access point as passed into the (configuration file when prepping the Pi).

• presentation: This directory contains scripts and documents that are created in the class.

  • cheat_sheets -- some markdown files with handy linux commands
  • codes -- different scripts and python modules for performing sensing and uploading data to the server.
  • plots -- some intermediate plots generated for the presentation

• setup: Containing setup files for ua-netinst

  • raspberrypi-ua-netinst-v1.5.1 -- v1.5.1 of installer (support until Pi 2B)
  • raspberrypi-ua-netinst-v2.3.0 -- v2.3.0 of installer (support until Pi 3B+)

The server directory contains scripts and modules for serving the ssh and vpn keys to students for interacting with the Pis and a dashboard for visualizing the uploaded data.

More information can be found in IoT and server directories.
