Exercise - Create the function app

  • 7 minutes

This guided project consists of the following exercises:

  • Create the Function App
  • Deploy an HTTP-trigger function
  • Test endpoint and review logs

In this exercise, you create a resource group and deploy a Function App using the serverless Flex Consumption plan. When you're done, you have a running Function App ready to host your first function.

This exercise includes the following tasks:

  • Prepare the environment
  • Configure the Function App
  • Verify the deployment

Outcome: A running Function App that uses the serverless consumption plan.

Tip

Pause after each major action and confirm the page status before moving on. This habit prevents compounding mistakes.

Task 1: Prepare the environment

Set up your Azure environment before you begin. You create a resource group to organize all the resources for this project together.

Warning

This project creates Azure resources that may incur charges. Complete the clean-up unit when you're done to avoid unintended expenses.

  1. Sign in to the Azure portal with an account that has permissions to create Function App resources.
  2. In the portal search bar, search for Resource groups and select Resource groups.
  3. Select + Create. Name the resource group rg-gp-functions-endpoint, choose your preferred region, and select Review + create then Create.

Task 2: Configure the Function App

Set up the Function App with serverless hosting. The Flex Consumption plan ensures you pay only for the execution time of your functions, making it cost-effective for occasional workloads.

  1. In the portal search bar, search for Function App and select Function App.
  2. Select Create.
  3. Select Flex Consumption as the hosting option and select Select.
  4. On the Basics tab, select rg-gp-functions-endpoint as the resource group.
  5. For Function App name, enter a globally unique name (for example, func-gp-endpoint- followed by your initials and a number).
  6. For Secure unique default host name, leave the default (On).
  7. For Region, keep the default or choose your preferred region.
  8. For Runtime stack, select Node.js.
  9. For Version, keep the latest available LTS option.
  10. For Instance size, leave the default (2048 MB).
  11. Select Review + create and then select Create.

Note

Validation step: Verify you selected all required settings before deployment: resource group, runtime stack (Node.js), region, and Flex Consumption hosting plan.

Note

Each exercise includes validation steps like this one. Track your results as you go—you'll review them all in the validation unit at the end of this module.

Task 3: Verify the deployment

Confirm that your Function App deployed successfully and is running.

  1. When deployment completes, select Go to resource.
  2. Confirm the Function App Overview page shows a Running status.

Note

Validation step: Confirm the Function App Overview page shows Running status and note the resource URL.
