Tutorial: Azure Function with FastAPI

This project is a demonstration of how Azure Functions can be used in combination with FastAPI.

Description

Demo API with the following endpoints:

• Product
  • Create
  • Read all products
  • Read a specific product
  • Patch product data
  • Delete a product

It should be noted that this is only a demo API. This API does not use a real database and therefore only uses a very simplified database manager with an "InMemory" database.

Getting started

Prerequisites

• Install the Azure Function Core Tools
• Python 3.9.0
• Azure Subscription (optional)

After that, create a python virtual environment, activate it and install the requirements.

Start the function

func start --python

In order to start the Azure Function via the Azure Function Core Tools (CLI) a activated virtual environment is required.

After starting Azure Functions you can access the documentation via this link:

Deploy to Azure:

This step requires an Azure Account. In case you do not have an Azure Account you can go ahead and create an account for free here.

Deploy ARM template to a existing resource group:

az deployment group create --resource-group <resource-group> --template-file .\az-func-template.json --parameters appName='<your_app_name>' storageAcctName='<your_storage_account_name>' hostingPlanName='<your_hosting_plan_name>'

func azure functionapp publish <your_function_app_name>

The original ARM template can be obtained from this blog by Ben Keen.
