Introduction

Welcome to the Container Communications Blueprint App for Particle!

This tutorial showcases a multi-container application where:

• A Redis instance acts as an event queue.
• A Python producer sends messages to the queue.
• A Node.js consumer listens for and processes messages.

Project description:

This tutorial introduces multi-container applications running on a Linux-based edge device like Tachyon or Raspberry Pi.

Using Redis as a queue, this blueprint demonstrates:

• How different services (Python & Node.js) can communicate asynchronously.
• How to use Redis Lists (RPUSH and BLPOP) as a lightweight event bus.
• The basics of Docker Compose to orchestrate multiple containers.
