通过 C# 创建 Azure VM 在创建资源组时抛出错误

Question

我正在尝试以编程方式创建 VM...实际上，按照书中的示例。在运行该程序之前，我继续通过门户 https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal 创建了一个 Azure AD 应用程序和服务主体。（附带一提，也许有人可以向我解释为什么需要这样做，但可以通过门户直接创建 VM 而无需创建服务 principal/AD 应用程序。）

在运行应用程序的同时，我能够成功创建管理客户端。下一步是创建资源组，这就是它失败并出现“System.Net.Http.HttpRequestException: 'No such host is known.'”错误的地方。请告知这里可能是什么问题。谢谢。

    //Create the management client. This will be used for all the operations we will perform in Azure.
    var credentials = SdkContext.AzureCredentialsFactory.FromFile("../../../azureauth.properties");
    var azure = Azure.Configure().WithLogLevel(HttpLoggingDelegatingHandler.Level.Basic).Authenticate(credentials).WithDefaultSubscription();

    //Create a resource group
    var groupName = "az204-ResourceGroup";
    var vmName = "az204VMTesting";
    var location = Region.USEast;
    var vNetName = "az204VNET";
    var vNetAddress = "172.16.0.0/16";
    var subnetName = "az204Subnet";
    var subnetAddress = "172.16.0.0/24";
    var nicName = "az204NIC";
    var adminUser = "azureadminuser";
    var adminPassword = "Pa$$w0rd!2019";

    Console.WriteLine($"Creating resource group {groupName} ... ");
//Below fails with 'No such host is known'
    var resourceGroup = azure.ResourceGroups.Define(groupName).WithRegion(location).Create();

我在我的系统中试过这个代码。试试这个代码

Answer 2

我通过将 AzureCredentialsFactory.FromFile 替换为 AzureCredentialsFactory.FromServicePrincipal 解决了这个问题。感谢 ShrutiJoshi-MT 的输入。我只是用必要的凭据创建了一个 json 文件。

我还有一些与授权相关的问题。事实证明我没有给 App Service 适当的授权级别。 post 帮助解决了这个问题：The client with object id does not have authorization to perform action 'Microsoft.DataFactory/datafactories/datapipelines/read' over scope.

最终代码：

string jsonString = File.ReadAllText("../../../azureauth.json");
AuthItem authItem = JsonSerializer.Deserialize<AuthItem>(jsonString);
var credentials = SdkContext.AzureCredentialsFactory
    .FromServicePrincipal(authItem.ClientId, authItem.SecretValue, authItem.TenantId, AzureEnvironment.AzureGlobalCloud);

//Create the management client. This will be used for all the operations we will perform in Azure.
var azure = Azure.Configure().WithLogLevel(HttpLoggingDelegatingHandler.Level.Basic).Authenticate(credentials).WithSubscription(authItem.Subscription);

//Create a resource group
var groupName = "az204-ResourceGroup";
var vmName = "az204VMTesting";
var location = Region.USEast;
var vNetName = "az204VNET";
var vNetAddress = "172.16.0.0/16";
var subnetName = "az204Subnet";
var subnetAddress = "172.16.0.0/24";
var nicName = "az204NIC";
var adminUser = "azureadminuser";
var adminPassword = "Pa$$w0rd!2019";

    Console.WriteLine($"Creating resource group {groupName} ... ");
    var resourceGroup = azure.ResourceGroups.Define(groupName).WithRegion(location).Create();

    //Every VM needs to be connected to a virtual network
    Console.WriteLine($"Creating virtual network {vNetName} ...");
    var network = azure.Networks.Define(vNetName)
        .WithRegion(location)
        .WithExistingResourceGroup(groupName)
        .WithAddressSpace(vNetAddress)
        .WithSubnet(subnetName, subnetAddress)
        .Create();

    //Any VM needs a network interface for connecting to the virtual network
    Console.WriteLine($"Creating network interface {nicName} ... ");
    var nic = azure.NetworkInterfaces.Define(nicName)
        .WithRegion(location)
        .WithExistingResourceGroup(groupName)
        .WithExistingPrimaryNetwork(network)
        .WithSubnet(subnetName)
        .WithPrimaryPrivateIPAddressDynamic()
        .Create();

    //Create the VM
    Console.WriteLine($"Creating VM {vmName} ... ");
    azure.VirtualMachines.Define(vmName)
        .WithRegion(location)
        .WithExistingResourceGroup(groupName)
        .WithExistingPrimaryNetworkInterface(nic)
        .WithLatestWindowsImage("MicrosoftWindowsServer", "WindowsServer", "2012-R2-Datacenter")
        .WithAdminUsername(adminUser)
        .WithAdminPassword(adminPassword)
        .WithComputerName(vmName)
        .WithSize(VirtualMachineSizeTypes.StandardDS2V2)
        .Create();
