This repository includes a very simple Python Flask web site, made for demonstration purposes only.

Opening the project

This project has Dev Container support, so it will be be setup automatically if you open it in Github Codespaces or in local VS Code with the Dev Containers extension.

If you're not using one of those options for opening the project, then you'll need to:

1. Create a Python virtual environment and activate it.

2. Install requirements:

   python3 -m pip install -r requirements.txt

Local development

1. Run the server:

   python3 -m flask run --port 50505 --debug

2. Click 'http://127.0.0.1:50505' in the terminal, which should open the website in a new tab.

3. Try the index page, try '/hello?name=yourname', and try other paths.

Deployment

This repo is set up for deployment on Azure App Service using the configuration files in the infra folder.

Steps for deployment:

1. Sign up for a free Azure account

2. Install the Azure Dev CLI. (If you opened this repository in a devcontainer, that part will be done for you.)

3. Provision and deploy all the resources:

   azd up

   It will prompt you to login and to provide a name (like "flask-app") and location (like "eastus"). Then it will provision the resources in your account and deploy the latest code.

4. When azd has finished deploying, you'll see an endpoint URI in the command output. Visit that URI, and you should see the front page of the 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.

5. When you've made any changes to the app code, you can just run:

   azd deploy

Costs

The app is currently configured to use the Free tier of Azure App Service, so it should incur no costs. See App Service Pricing for more details on the tier pricing levels and the limitations of the free tier.
