QR_generator:

This repository contains an example application used for testing the Segno library and local Kubernetes deployment using Minikube.

Overview

The purpose of this project is to demonstrate how to integrate and test the Segno library in a real-world application, as well as how to deploy it locally using Minikube. Segno is a Python library for generating QR codes, and this example app showcases its usage within a larger project.

Features

• Integration of Segno library for QR code generation with Flask app.
• Testing local deployment of the application using Minikube.

Getting Started:

Local development

Requires uv and just.

just install      # install all dependencies (including dev)
just runserver    # start Flask on http://127.0.0.1:5000/
just test         # run all tests (excluding slow)
just lint         # ruff, ty, codespell, bandit
just git-precommit  # run pre-commit hooks on all files

Note: docker-compose.yml mounts the working directory into the container (.:/app) for development convenience. Remove or replace the volumes section before using it in production.

Commands reminder:

To run on my configuration:

docker context use default
docker-compose up -d --build
docker image save -o image.tar qr_generator-web:latest

minikube delete --all --purge
minikube start
minikube image load image.tar

kubectl apply -f .\qrgen-deploy.yaml
kubectl apply -f .\qrgen-service.yaml
kubectl apply -f .\ingress.yaml

minikube tunnel

Checks:

kubectl get pods
docker images

Default run:

http://127.0.0.1:5000/
