This is a Python web app using the Django framework and the Azure Database for PostgreSQL relational database service. The Django app is hosted in a fully managed Azure App Service. This app is designed to be be run locally and then deployed to Azure. You can either deploy this project by following the tutorial Deploy a Python (Django or Flask) web app with PostgreSQL in Azure or by using the Azure Developer CLI (azd) according to the instructions below.
The requirements.txt has the following packages:
| Package | Description |
|---|---|
| Django | Web application framework. |
| pyscopg2-binary | PostgreSQL database adapter for Python. |
| python-dotenv | Read key-value pairs from .env file and set them as environment variables. In this sample app, those variables describe how to connect to the database locally. This package is used in the manage.py file to load environment variables. |
| whitenoise | Static file serving for WSGI applications, used in the deployed app. This package is used in the azureproject/production.py file, which configures production settings. |
This project is designed to work well with the Azure Developer CLI, which makes it easier to develop apps locally, deploy them to Azure, and monitor them.
This project has devcontainer support, so you can open it in Github Codespaces or local VS Code with the Dev Containers extension. If you're unable to open the devcontainer, then it's best to first create a Python virtual environment and activate that.
- Install the requirements:
pip install -r requirements.txt-
Create an
.envfile using.env.sampleas a guide. Set the value ofDBNAMEto the name of an existing database in your local PostgreSQL instance. Set the values ofDBHOST,DBUSER, andDBPASSas appropriate for your local PostgreSQL instance. If you're in the devcontainer, copy the values from.env.sample.devcontainer. -
Run the migrations: (or use VS Code "Run" button and select "Migrate")
python manage.py migrate- Run the local server: (or use VS Code "Run" button and select "Run server")
python manage.py runserverThis repo is set up for deployment on Azure App Service (w/PostGreSQL server) using the configuration files in the infra folder.

Steps for deployment:
- Sign up for a free Azure account
- Install the Azure Dev CLI. (If you opened this repository in a devcontainer, that part will be done for you.)
- Provision and deploy all the resources:
azd upIt will prompt you to login and to provide a name (like "django-app") and location (like "eastus"). Then it will provision the resources in your account and deploy the latest code. If you get an error with deployment, changing the location (like to "centralus") can help, as there are availability constraints for some of the resources.
- When
azdhas finished deploying, you'll see an endpoint URI in the command output. Visit that URI, and you should see the front page of the restaurant review app! 🎉 If you see an error, open the Azure Portal from the URL in the command output, navigate to the App Service, select Logstream, and check the logs for any errors.
- If you'd like to access
/admin, you'll need a Django superuser. Navigate to the Azure Portal for the App Service, select SSH, and run this command:
python manage.py createsuperuser- When you've made any changes to the app code, you can just run:
azd deployThis project includes a Github workflow for deploying the resources to Azure on every push. That workflow requires several Azure-related authentication secrets to be stored as Github action secrets. To set that up, run:
azd pipeline configThe deployed resources include a Log Analytics workspace with an Application Insights dashboard to measure metrics like server response time.
To open that dashboard, just run:
azd monitor --overviewIf you're working with this project and running into issues, please post in Discussions.
