Summary

Example microservices implementation using Node.js and Docker. Below is an architectural diagram depicting the composition of services that make up the project. When everything is working a frontend web application is accessible that will display a set of graphs using sensor data. The sensor data is either generated by the smartthings microservice or is sent to the microservice from a SmartThings hub running a Sensor SmartApp.

Prerequisites

1. npm 4.x or npm 5.3.1 or newer.
2. A recent docker version

Challenges

The workshop is divided into challenges. In each challenge folder there is a readme that explains the requirements for the challenge. In the challenge folder is also a solution file that explains how to solve the challenge. Below is a list of the different challenges.

1. Startup the frontend with node
2. Startup the frontend with docker
3. Startup the gateway and 2 frontend instances with docker-compose
4. Scale the frontend behind the gateway using docker with ContainerPilot
5. Add smartthings, NATS, a worker (temperature), serializer, and influxdb
6. Add the humidity and motion workers
7. Add prometheus and connect telemetry
