Azure retrieving the PublicIPAddress of VirtualMachines from Azure Java SDK

Question

As the answer was Page Not Found, I was trying to retrieve size of Public IPs with the following code

Configuration config = ManagementConfiguration.configure(
          


        

Answer 1

The issue was caused by using the incorrect authentication.

The authentication code below just works for Azure Service Management.

Configuration config = ManagementConfiguration.configure(
          new URI("https://management.core.windows.net), 
          subscriptionId,
          keyStoreLocation, // the file path to the JKS
          keyStorePassword, // the password for the JKS
          KeyStoreType.jks // flags that I'm using a JKS keystore
        );

Authenticating for Azure Resource Management, the doc "Authenticating Azure Resource Management request"( https://msdn.microsoft.com/en-us/library/azure/dn790557.aspx) says "All of the tasks that you do on resources using the Azure Resource Manager must be authenticated with Azure Active Directory. ".

So you need to modify the authenticate configuration code with your subscription-id, tenant-id, client-id and client-secret as follow:

private static AuthenticationResult getAccessTokenFromServicePrincipalCredentials() throws
            ServiceUnavailableException, MalformedURLException, ExecutionException, InterruptedException {
        AuthenticationContext context;
        AuthenticationResult result = null;
        ExecutorService service = null;
        try {
            service = Executors.newFixedThreadPool(1);
            // TODO: add your tenant id
            context = new AuthenticationContext("https://login.windows.net/" + "",
                    false, service);
            // TODO: add your client id and client secret
            ClientCredential cred = new ClientCredential("",
                    "");
            Future future = context.acquireToken(
                    "https://management.azure.com/", cred, null);
            result = future.get();
        } finally {
            service.shutdown();
        }

        if (result == null) {
            throw new ServiceUnavailableException(
                    "authentication result was null");
        }
        return result;
    }


Configuration config = ManagementConfiguration.configure(
          null,
          new URI("https://management.core.windows.net), 
          "",
          getAccessTokenFromServicePrincipalCredentials()
.getAccessToken()
        );
