Part 1 covered building a FastAPI application with a Dockerfile and getting it running locally. Here you take that same application and ship it to Fly.io, then wire up a three-stage GitHub Actions pipeline that tests, builds, and deploys on every push to main. By the end, you have a production URL, a health check […]

Manually configuring hundreds of network devices creates unnecessary friction, even when the differences between configs are minimal. Jinja templating in Catalyst Center lets you parameterise device configurations, so you write a template once and provision devices at scale by feeding in different variable values. This approach eliminates copy-paste errors and makes configuration management auditable and […]

Now that we have an ESP32 connected to our network and running python, the next task is to connect a two switch relay and be able to control it. Eventually we will do this via MQTT, but for now a web server will be enabled on the board to allow manual control of the relay […]
In our previous post we uploaded a python script to the ESP32 to run on boot. This time we will connect the ESP32 to our wireless network. Firstly I am going to create a config.py file to store any configuration parameters we are going to use. In this case we simply have the SSID and […]
In a previous post we flashed a W32-WROOM-32 with MicroPython and successfully got to an interactive python prompt via serial. Now we will create a simple python script and upload it to the ESP32 and have it run on boot. First, lets create a really simple python script -: import time print(‘Hello world! I can […]
