Quickstart: Create an Azure Managed CCF resource using the Azure SDK for Java

  • Article

Azure Managed CCF (Managed CCF) is a new and highly secure service for deploying confidential applications. For more information on Azure Managed CCF, see About Azure Managed Confidential Consortium Framework.

If you don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

Setup

This quickstart uses the Azure Identity library, along with Azure CLI or Azure PowerShell, to authenticate user to Azure Services. Developers can also use Visual Studio or Visual Studi- OpenSSL on a computer running Windows or Linux.o Code to authenticate their calls. For more information, see Authenticate the client with Azure Identity client library.

Sign in to Azure

Sign in to Azure using the Azure CLI az login command or the Azure PowerShell Connect-AzAccount cmdlet.

az login

If the CLI or PowerShell can open your default browser, it will do so and load an Azure sign-in page. Otherwise, visit https://aka.ms/devicelogin and enter the authorization code displayed in your terminal.

If prompted, sign in with your account credentials in the browser.

Install the dependencies

<dependency>
    <groupId>com.azure.resourcemanager</groupId>
    <artifactId>azure-resourcemanager-confidentialledger</artifactId>
    <version>1.0.0-beta.3</version>
</dependency>

Create a resource group

A resource group is a logical container into which Azure resources are deployed and managed. Use the Azure PowerShell New-AzResourceGroup cmdlet to create a resource group named myResourceGroup in the southcentralus location.

New-AzResourceGroup -Name "myResourceGroup" -Location "SouthCentralUS"

Register the resource provider

The Azure Managed CCF resource type must be registered in the subscription before creating a resource.

az feature registration create --namespace Microsoft.ConfidentialLedger --name ManagedCCF

az provider register --namespace Microsoft.ConfidentialLedger

Create members

Generate a key pair for the member. After the following commands complete, the member's public key is saved in member0_cert.pem and the private key is saved in member0_privk.pem.

openssl ecparam -out "member0_privk.pem" -name "secp384r1" -genkey
openssl req -new -key "member0_privk.pem" -x509 -nodes -days 365 -out "member0_cert.pem" -"sha384" -subj=/CN="member0"

Create the Java application

The Azure SDK for Java library (azure-resourcemanager-confidentialledger) allows operations on Managed CCF resources, such as creation and deletion, listing the resources associated with a subscription, and viewing the details of a specific resource. The following piece of code creates and views the properties of a Managed CCF resource.

import com.azure.core.management.AzureEnvironment;
import com.azure.core.management.exception.ManagementException;
import com.azure.core.management.profile.AzureProfile;
import com.azure.identity.DefaultAzureCredentialBuilder;
import com.azure.resourcemanager.confidentialledger.ConfidentialLedgerManager;
import com.azure.resourcemanager.confidentialledger.fluent.models.ManagedCcfInner;
import com.azure.resourcemanager.confidentialledger.models.DeploymentType;
import com.azure.resourcemanager.confidentialledger.models.LanguageRuntime;
import com.azure.resourcemanager.confidentialledger.models.ManagedCcfProperties;
import com.azure.resourcemanager.confidentialledger.models.MemberIdentityCertificate;
import java.util.*;

public class AzureJavaSdkClient {
    public static void main(String[] args) {
      try {
          AzureProfile profile = new AzureProfile("<tenant id>","<subscription id>", AzureEnvironment.AZURE);
          ConfidentialLedgerManager manager = ConfidentialLedgerManager.authenticate(new DefaultAzureCredentialBuilder().build(), profile);

          MemberIdentityCertificate member0 = new MemberIdentityCertificate()
              .withCertificate("-----BEGIN CERTIFICATE-----\nMIIBvjCCAUSgAwIBAgIUA0YHcPpUCtd...0Yet/xU4G0d71ZtULNWo\n-----END CERTIFICATE-----")
              .withTags(Map.of("Dept", "IT"));
          List<MemberIdentityCertificate> members = new ArrayList<MemberIdentityCertificate>();
          members.add(member0);

          DeploymentType deployment = new DeploymentType().withAppSourceUri("").withLanguageRuntime(LanguageRuntime.JS);
          ManagedCcfProperties properties = new ManagedCcfProperties()
              .withDeploymentType(deployment)
              .withNodeCount(5)
              .withMemberIdentityCertificates(members);

          ManagedCcfInner inner = new ManagedCcfInner().withProperties(properties).withLocation("southcentralus");

          // Send Create request
          manager.serviceClient().getManagedCcfs().create("myResourceGroup", "confidentialbillingapp", inner);

          // Print the Managed CCF resource properties
          ManagedCcfInner app = manager.serviceClient().getManagedCcfs().getByResourceGroup("myResourceGroup", "confidentialbillingapp");
          printAppInfo(app);

          // Delete the resource
          manager.serviceClient().getManagedCcfs().delete("myResourceGroup", "confidentialbillingapp");
        } catch (ManagementException ex) {
            // The x-ms-correlation-request-id is located in the Header
            System.out.println(ex.getResponse().getHeaders().toString());
            System.out.println(ex);
        }
    }

    private static void printAppInfo(ManagedCcfInner app) {
        System.out.println("App Name: " + app.name());
        System.out.println("App Id: " + app.id());
        System.out.println("App Location: " + app.location());
        System.out.println("App type: " + app.type());
        System.out.println("App Properties Uri: " + app.properties().appUri());
        System.out.println("App Properties Language Runtime: " + app.properties().deploymentType().languageRuntime());
        System.out.println("App Properties Source Uri: " + app.properties().deploymentType().appSourceUri());
        System.out.println("App Properties NodeCount: " + app.properties().nodeCount());
        System.out.println("App Properties Identity Uri: " + app.properties().identityServiceUri());
        System.out.println("App Properties Cert 0: " + app.properties().memberIdentityCertificates().get(0).certificate());
        System.out.println("App Properties Cert tags: " + app.properties().memberIdentityCertificates().get(0).tags());
    }
}

Clean up resources

Other Managed CCF articles can build upon this quickstart. If you plan to continue on to work with subsequent quickstarts and tutorials, you might wish to leave these resources in place.

Otherwise, when you're finished with the resources created in this article, use the Azure CLI az group delete command to delete the resource group and all its contained resources.

az group delete --resource-group myResourceGroup
