- 10. Understanding App Service CI / CD • Kudu and Oryx are the two App Service engines controlling CI and CD • Kudu does a web-hook triggered pull from source control and performs local compile and deployment • Kudu recognises Python apps based on *.py, requirements.txt or runtime.txt • Kudu automatically: • Activates a virtual environment • Uses PIP to restore modules in requirements.txt. • Configure via Azure Portal easiest, but also possible via CLI • Both Kudu and Oryx are open source and available on GitHub.
- 11. Python features on App Service • The Python runtime is deployed from a baseline Docker image • Docker image: • Uses Gunicorn WSGI HTTP Server • Includes Flask web framework. Run Django (or other) frameworks by using requirements.txt for installation • Is built using a Dockerfile published on GitHub • App Settings can be accessed as environment variables using os.eviron • Troubleshoot runtime issues via web SSH and streaming logs • Utilise Managed Service Identities (MSI) to access other Azure resources.
