Prerequisites

You should have the following development tools installed on your local machine.

• Azure Functions
• VS Code
• Maven (optional)

You will also need accounts for the following services

• Microsoft Azure

Running the sample

Build and test locally

Before deploying to App Service, build and run the Function locally.

mvn clean package
mvn azure-functions:run

Open a browser to http://localhost:7071/api/auth and should display 401 - UNAUTHORIZED, which is normal because we are not making the call with calls with certificate.

Publish the application to a Function App

Now that the Function App works locally, we will push the jar to our registry so our Function App can run the jar. First, run the below command to be login into Azure Cli and deploy to a specific Function App.

• Deploy the function project to Azure

az login
mvn azure-functions:deploy

Once your Function App is deployed, you can now just simply enable Incoming Client Certificate on Azure so incoming requests are challeneged.
