How to Deploy Python to Azure App Service Quickly

To deploy Python to Azure App Service, create a web app with a Python runtime using az webapp create, then push your code using git push or deploy via ZIP. Azure App Service automatically detects Python apps and runs them with the specified runtime.

Syntax

Use Azure CLI commands to create and deploy your Python app to Azure App Service.

• az webapp create --resource-group <group> --plan <plan> --name <app_name> --runtime <python_version>: Creates the app with Python runtime.
• git push azure main: Pushes your code to Azure for deployment.
• az webapp deployment source config-zip --resource-group <group> --name <app_name> --src <zip_file>: Deploys zipped app code.

bash

az webapp create --resource-group myResourceGroup --plan myAppServicePlan --name myPythonApp --runtime "PYTHON|3.9"
git remote add azure https://myPythonApp.scm.azurewebsites.net:443/myPythonApp.git
git push azure main

Example

This example shows how to create an Azure App Service for Python 3.9, add Azure as a git remote, and push your app code for deployment.

bash

az group create --name myResourceGroup --location eastus
az appservice plan create --name myAppServicePlan --resource-group myResourceGroup --sku B1 --is-linux
az webapp create --resource-group myResourceGroup --plan myAppServicePlan --name myPythonApp --runtime "PYTHON|3.9" --deployment-local-git

git remote add azure https://myPythonApp.scm.azurewebsites.net:443/myPythonApp.git

git push azure main

Output

Creating resource group 'myResourceGroup'...
Resource group created.
Creating App Service plan 'myAppServicePlan'...
App Service plan created.
Creating web app 'myPythonApp' with Python 3.9 runtime...

Common Pitfalls

Common mistakes when deploying Python apps to Azure App Service include:

• Not specifying the correct Python runtime version in --runtime.
• Forgetting to create a Linux App Service plan when deploying Python apps (Python apps require Linux plans).
• Not committing your code before pushing to Azure git remote.
• Missing a requirements.txt file for dependencies, causing runtime errors.
• Not setting the startup command if your app needs one (like gunicorn for Flask/Django).

bash

Wrong:
az webapp create --resource-group myResourceGroup --plan myAppServicePlan --name myPythonApp --runtime "PYTHON|2.7"

Right:
az webapp create --resource-group myResourceGroup --plan myAppServicePlan --name myPythonApp --runtime "PYTHON|3.9"

Quick Reference

Summary tips for deploying Python apps to Azure App Service:

• Use Linux App Service plans for Python apps.
• Specify Python runtime version with --runtime.
• Include requirements.txt for dependencies.
• Use Azure CLI for creating and deploying apps.
• Push code via Git or deploy ZIP files.

Key Takeaways

Create a Linux App Service plan and specify the Python runtime version when creating the web app.

Deploy your Python code by pushing to the Azure Git remote or by uploading a ZIP file.

Always include a requirements.txt file to install dependencies automatically.

Set a startup command if your app needs one to run correctly on Azure.

Use Azure CLI commands for smooth and repeatable deployment steps.
