The most basic Flask "hello world" application as an AZD template ready for Azure App Service

1. Install AZD and run the following command to initialize the project.

azd init --template tonybaloney/simple-flask-azd

This command will clone the code to your current folder and prompt you for the following information:

• Environment Name: This will be used as a prefix for the resource group that will be created to hold all Azure resources. This name should be unique within your Azure subscription.

2. Run the following command to build a deployable copy of your application, provision the template's infrastructure to Azure and also deploy the applciation code to those newly provisioned resources.

azd up

This command will prompt you for the following information:

• Azure Location: The Azure location where your resources will be deployed.
• Azure Subscription: The Azure Subscription where your resources will be deployed.

NOTE: This may take a while to complete as it executes three commands: azd package (builds a deployable copy of your application), azd provision (provisions Azure resources), and azd deploy (deploys application code). You will see a progress indicator as it packages, provisions and deploys your application.

3. Then make changes to app.py and run azd deploy again to update your changes.

This uses the F1 (free) SKU for app service, which has limited CPU and RAM resources.

See the pricing calculator for details on paid SKUs replace the SKU option with a suitable choice.
