Containerizing Python and Deploying to IoT and Edge Devices

Python developers certainly understand how flexible and versatile python applications can be, and could easily name a dozen (or more) potential use cases for python. But let's focus on one very important and rapidly expanding use case, the Internet of Things. In the world of IoT, python can be used for reading data from sensors, enabling Artificial Intelligence and Machine Learning at the edge, and building smart cities that adapt and interact with humans and objects. Developing all of this locally on your laptop or a small prototype device like a Raspberry Pi or Beaglebone is great, but when it comes to deploying devices out into the world, special considerations need to be taken. This is a great opportunity to make use of Docker containers, so let's explore how to place your Python into a container, and push it onto devices, using the balenaCloud platform.

Workshop Agenda

  • We will start off with a simple python application, running locally.
  • Next, we will wrap a container around it.
  • Then, we will push that container onto a Raspberry Pi attached to balenaCloud, functioning as an IoT device.
  • Next, we'll make a change to the application, and deploy the newly updated container to the Pi.
  • Finally, we can scale up the number of devices, and talk about lessons learned for devices in remote locations.

Workshop Details

Normally this type of content would be delivered in a classroom setting, but since PyCon India is a virtual conference this year, we're going to have to get creative! Not to worry though, I will explain and demonstrate each of the steps above, on camera and with screenshare and some prepared slides, and will help attendees complete each item. You will need a Raspberry Pi if you are going to follow along, preferably a Pi 3 or Pi 4.

Questions and Discussion

We'll do our best to make it an interactive session, and make sure everyone follows along and completes each step. I will present each task, demonstrate it, then assist folks with completing the step, prior to moving on. Of course, we'll also be sure to provide follow up contact info and our community / social channels for anything else!

Prerequisites:

  • Basic knowledge of Docker Containers, just the high level concepts are fine in order to follow along.
  • A Raspberry Pi, SD Card, and power supply, in order to follow along and participate.
  • If your desktop or laptop PC doesn't have an SD Card, you may need a USB adapter in order to flash the SD Card.

Content URLs:

These will be built and shared later, but balena has many existing sample projects and GitHub repo's containing containerized python applications. For example, balenaSense is a nice python-driven environmental monitoring solution for IoT devices: https://github.com/balenalabs/balena-sense
