python-calculator-webapp

A small Python (Flask) calculator application used across the KodeKloud AZ-400 labs. Import this repository into Azure Repos (or use it directly) — each lab uses the pieces it needs.

Application

Path	Purpose
python_calc.py	Flask web calculator (reads optional Azure App Configuration via AZURE_APPCONFIG_CONNECTION_STRING for a dynamic banner + the SalesWeekend feature flag; falls back to safe defaults)
src/calc.py	Calculator library (safe_divide, add, subtract, multiply)
tests/test_calc.py	Unit tests (pytest)
requirements.txt	Python dependencies
Dockerfile, docker-compose.yml	Container build / local compose

Infrastructure (infra/)

File	Purpose
webapp.bicep	Linux Python Web App
webapp-appconfig.bicep	Linux Python Web App for the dynamic config / feature flags lab (connection string set post-deploy)
acr.bicep	Azure Container Registry
webapp-docker.bicep	Linux Web App for Containers
webapp-to-acr-roleassignment.bicep	Grants the Web App's managed identity AcrPull
main.bicep + modules/webapp.bicep	Bicep deployments lab — main.bicep uses the web app module and has the storage account inline; the lab walks you through extracting modules/storage.bicep

Pipelines (pipelines/)

File	Lab
python-calc-docker-ci.yml / python-calc-docker-cd.yml	Deploy Docker containers to Azure App Service
python-multi-stage.yml	Configure Pipelines as Code with YAML
python-calc-ci.yml	Release Gates + Dynamic Configuration labs (CI: build + publish the Website artifact)
python-functional-tests.yml	Set up and run functional tests
python-calc-ci-dockercompose.yml / python-calc-cd-aci.yml	Integrate Azure Key Vault (Docker Compose CI / ACI CD)
python-calc-cd-appconfig.yml	Enable Dynamic Configuration and Feature Flags (CD: deploy the Web App, triggered by python-calc-ci)
bicep-deploy.yml	Deployments using Azure Bicep templates
publish-package.yml	Package Management with Azure Artifacts
loadtest-pipeline.yml	Monitor Application Performance with Azure Load Testing (runs the JMeter test from CI/CD)

Other

Path	Purpose
functional-tests/	Selenium UI tests (run against the deployed app)
loadtest/	JMeter test plan (calculator.jmx) + Azure Load Testing config (loadtest.yaml)
package/	The kk-calculator distributable package (Azure Artifacts lab)
