Usage

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

azd init --template Azure-Samples/azd-simple-flask-appservice

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. Login to your Azure account.

azd auth login

3. 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.

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

Access the free App Service Tier

As the template comes, it is set to a basic plan (see pricing guide), but if you want to get started for free, you can easily update the template before you run azd up to leverage the free plan or the discounted developer plan.

Go to the /infra/resources.bicep file and update line 57, where the SKU is currently set to “B1”. Change this to “F1” to deploy up to 10 App Service apps for free on the free plan (or “D1” for the discounted developer rate if you have more than 10 to deploy concurrently).

Notes

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.
