Get Public IP of VM in ScaleSet

Query/Question How can I get the public IP of each VM in a scale set?

var _azure = Azure
            .Configure()
            .WithLogLevel(HttpLoggingDelegatingHandler.Level.Basic)
            .Authenticate(GetCredentials(credentials))
            .WithSubscription(credentials.Subscription);

var scaleSets = await _azure.VirtualMachineScaleSets.ListAsync(true, cancellationToken);

// example of how to get the private ip:
var privateIp = scaleSets.First().VirtualMachines.List().First().ListNetworkInterfaces().First().PrimaryPrivateIP;

// PrimaryPublicIp does not exist:
var publicIp = scaleSets.First().VirtualMachines.List().First().ListNetworkInterfaces().First().PrimaryPublicIP;

Setup (please complete the following information if applicable):

• OS: Windows
• IDE : JetBrains Rider
• Version of the Library used:
  • Microsoft.Azure.Management.Fluent Version=“1.36.1”

@weidongxu-microsoft the API is documented in the NW spec here: https://github.com/Azure/azure-rest-api-specs/blob/master/specification/network/resource-manager/Microsoft.Network/stable/2020-08-01/vmssPublicIpAddress.json

Hope this clarifies the question. Closing the issue, feel free to reopen if there are additional questions on this.

Here is a workaround in c#:

Types:

public sealed record PublicIpConfiguration(IList<IpConfiguration> Value);

public sealed record IpConfiguration(string Name, string Id, string Etag, Properties Properties);

public sealed record Properties(string ProvisioningState, string ResourceGuid, string IpAddress, string PublicIPAddressVersion, string PublicIPAllocationMethod, string IdleTimeoutInMinutes, IpConfigurationId IpConfiguration);

public sealed record IpConfigurationId(string Id);

Call:

var client = RestClient
    .Configure()
    .WithEnvironment(AzureEnvironment.AzureGlobalCloud)
    .WithCredentials(_credentials)
    .Build();

var url = $"https://management.azure.com/subscriptions/{_azure.SubscriptionId}/resourceGroups/{scaleSet.ResourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{scaleSet.Name}/publicipaddresses?api-version=2017-03-30";

var request = new HttpRequestMessage(HttpMethod.Get, url);

client.Credentials.ProcessHttpRequestAsync(request, cancellationToken).GetAwaiter().GetResult();
var httpClient = new HttpClient();
var response = httpClient.SendAsync(request, HttpCompletionOption.ResponseHeadersRead, cancellationToken).GetAwaiter().GetResult();

var stream = await response.Content.ReadAsStringAsync(cancellationToken);
var output = JsonConvert.DeserializeObject<PublicIpConfiguration>(stream);
