Number Facts with Python Web Apps

In this lab, you will learn how to deploy a python app to App Service using the Azure CLI.

You will learn to:

  • Use az webapp up to quickly provision Azure resources and deploy your app to Azure App Service.
  • Leverage the local context feature of Azure CLI to ease management operations.

Prerequisites

Deploy the app to Azure using the Azure CLI

Create a local copy of this repository

  • You can create a local clone, or just download the *.zip archive
  • Open a terminal window and navigate to the folder containing the Web App sample

Login with Azure CLI

Log in to Azure using the az login command. This will open a browser window where you can authenticate. See az login.

Choose the subscription you will use with the az account set --subscription command. You will only need to do this if you have more than one Azure subscription. See az account.

Deploy your application with az webapp up

App Service provides az webapp up as a quick way to get started with the service. We are going to leverage that functionality to:

  • Create all the necessary resources to host our app
  • Build and package the application
  • Publish the app to the cloud.

Run the following command:

  az webapp up -n <name> -l <location> --sku FREE

  • name should be a unique string. name is used as the Azure resource name as well as part of the url for your app.

  • location will determine the Azure region where your resource will be created. You can get a list of supported locations with az account list-locations.

  • sku lets you choose across different service offerings. For this sample we will use the FREE option, however for production we recommend P1V2 or higher. Learn more about App Service Pricing

Note: App Service has limits on how many free plans you can have in a subscription. If you have problems creating a free plan, try choosing a different region, or using one of the paid options such as B1.

Running az webapp up for the first time will take a few minutes to complete. Behind the scenes it will provision all the necessary resources including an Azure Resource Group, App Service plan and Azure Webapp.

Locally az webapp up creates a directory called .azure this is used to store the local context. Local context stores the configuration that you passed in through parameters to az webapp up to use later. For example you can now use az webapp browse without any more parameters to browse to your app or az webapp logs tail to stream the runtime logs of your application.

You can also modify this sample and run az webapp up again with no parameters to push any change you have made to the resources you already created on the first run.
