Azure Function App with Docker

This project demonstrates how to create an Azure Function App using Python and Docker.

Prerequisites

• Azure CLI
• Docker
• Python 3.10
• Azure Functions Core Tools

Getting Started

1. Initialize the Function App

First, create a new Azure Function App project:

func init az_func_app_with_docker --python
cd az_func_app_with_docker

2. Create a New Function

Create a new HTTP-triggered function:

func new --name HelloWorld --template "HTTP trigger" --authlevel "anonymous"

3. Update the Function Code

Update the function code in function_app.py as needed.

4. Create a Dockerfile

Ensure you have a Dockerfile in the root of your project with the necessary content.

5. Build and Run the Docker Container

Build the Docker image:

docker build -t az-func-app .

Run the Docker container:

docker run -p 8080:80 az-func-app

6. Test the Function

You can test the function by navigating to http://localhost:8080/api/HelloWorld in your web browser or using a tool like curl:

curl http://localhost:8080/api/HelloWorld?name=Azure

You should see the response:

Hello, Azure. This HTTP triggered function executed successfully.

7. Deploy to Azure

Login to Azure:

az login

Create a resource group:

az group create --name myResourceGroup --location eastus

Create a storage account:

az storage account create --name mystorageaccount --location eastus --resource-group myResourceGroup --sku Standard_LRS

Create a function app:

az functionapp create --resource-group myResourceGroup --consumption-plan-location eastus --runtime python --functions-version 3 --name myfuncapp --storage-account mystorageaccount

Deploy the function app:

func azure functionapp publish myfuncapp

Conclusion

You have successfully created and deployed an Azure Function App using Python and Docker.
