部署云服务（外延支持）

使用该 SDK 部署云服务（外延支持）：

安装 Azure 计算 SDK NuGet 包，并使用标准身份验证方法初始化客户端：

    public class CustomLoginCredentials : ServiceClientCredentials
    {
        private string AuthenticationToken { get; set; }
        public override void InitializeServiceClient<T>(ServiceClient<T> client)
        {
            var authenticationContext = new AuthenticationContext("https://login.chinacloudapi.cn/{tenantID}");
            var credential = new ClientCredential(clientId: "{clientID}", clientSecret: "{clientSecret}");
            var result = authenticationContext.AcquireTokenAsync(resource: "https://management.core.chinacloudapi.cn/", clientCredential: credential);
            if (result == null) throw new InvalidOperationException("Failed to obtain the JWT token");
            AuthenticationToken = result.Result.AccessToken;
        }
        public override async Task ProcessHttpRequestAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            if (request == null) throw new ArgumentNullException("request");
            if (AuthenticationToken == null) throw new InvalidOperationException("Token Provider Cannot Be Null");
            request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", AuthenticationToken);
            request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            //request.Version = new Version(apiVersion);
            await base.ProcessHttpRequestAsync(request, cancellationToken);
        }
    }

    var creds = new CustomLoginCredentials();
    m_subId = Environment.GetEnvironmentVariable("AZURE_SUBSCRIPTION_ID");
    ResourceManagementClient m_ResourcesClient = new ResourceManagementClient(creds);
    NetworkManagementClient m_NrpClient = new NetworkManagementClient(creds);
    ComputeManagementClient m_CrpClient = new ComputeManagementClient(creds);
    StorageManagementClient m_SrpClient = new StorageManagementClient(creds);
    m_ResourcesClient.SubscriptionId = m_subId;
    m_NrpClient.SubscriptionId = m_subId;
    m_CrpClient.SubscriptionId = m_subId;
    m_SrpClient.SubscriptionId = m_subId;

通过安装 Azure 资源管理器 NuGet 包来创建新的资源组：

var resourceGroups = m_ResourcesClient.ResourceGroups;
var m_location = “East US”;
var resourceGroupName = "ContosoRG";//provide existing resource group name, if created already
var resourceGroup = new ResourceGroup(m_location); 
resourceGroup = await resourceGroups.CreateOrUpdateAsync(resourceGroupName, resourceGroup);

创建存储帐户和容器，用于存储部署的包（.cspkg 或 .zip）文件和配置 (.cscfg) 文件。安装 Azure 存储 NuGet 包。如果使用的是现有存储帐户，则此步骤是可选的。存储帐户名称必须是唯一的。

string storageAccountName = “ContosoSAS”
var stoInput = new StorageAccountCreateParameters
   {
        Location = m_location,
        Kind = Microsoft.Azure.Management.Storage.Models.Kind.StorageV2,
        Sku = new Microsoft.Azure.Management.Storage.Models.Sku(SkuName.StandardRAGRS),
    };
        StorageAccount storageAccountOutput = m_SrpClient.StorageAccounts.Create(rgName,
        storageAccountName, stoInput);
        bool created = false;
        while (!created)
           {
                Thread.Sleep(600);
                var stos = m_SrpClient.StorageAccounts.ListByResourceGroup(rgName);
                created =
                stos.Any(
                    t =>
                    StringComparer.OrdinalIgnoreCase.Equals(t.Name, storageAccountName));
            }

StorageAccount storageAccountOutput = m_SrpClient.StorageAccounts.GetProperties(rgName, storageAccountName);.
var accountKeyResult = m_SrpClient.StorageAccounts.ListKeysWithHttpMessagesAsync(rgName, storageAccountName).Result;
CloudStorageAccount storageAccount = new CloudStorageAccount(new StorageCredentials(storageAccountName, accountKeyResult.Body.Keys.FirstOrDefault(). Value), useHttps: true);

var blobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer container = blobClient.GetContainerReference("sascontainer");
container.CreateIfNotExistsAsync().Wait();
sharedAccessBlobPolicy sasConstraints = new SharedAccessBlobPolicy();
sasConstraints.SharedAccessStartTime = DateTime.UtcNow.AddDays(-1);
sasConstraints.SharedAccessExpiryTime = DateTime.UtcNow.AddDays(2);
sasConstraints.Permissions = SharedAccessBlobPermissions.Read | SharedAccessBlobPermissions.Write;

将包（.cspkg 或 .zip）文件上传到存储帐户。包 URL 可以是任何存储帐户的共享访问签名 (SAS) URI。

CloudBlockBlob cspkgblockBlob = container.GetBlockBlobReference(“ContosoApp.cspkg”);
cspkgblockBlob.UploadFromFileAsync(“./ContosoApp/ContosoApp.cspkg”). Wait();

//Generate the shared access signature on the blob, setting the constraints directly on the signature.
string cspkgsasContainerToken = cspkgblockBlob.GetSharedAccessSignature(sasConstraints);

//Return the URI string for the container, including the SAS token.
string cspkgSASUrl = cspkgblockBlob.Uri + cspkgsasContainerToken;

将配置 (.cscfg) 文件上传到存储帐户。将服务配置指定为字符串 XML 或 URL 格式。

CloudBlockBlob cscfgblockBlob = container.GetBlockBlobReference(“ContosoApp.cscfg”);
cscfgblockBlob.UploadFromFileAsync(“./ContosoApp/ContosoApp.cscfg”). Wait();

//Generate the shared access signature on the blob, setting the constraints directly on the signature.
string sasCscfgContainerToken = cscfgblockBlob.GetSharedAccessSignature(sasConstraints);

//Return the URI string for the container, including the SAS token.
string cscfgSASUrl = cscfgblockBlob.Uri + sasCscfgContainerToken;

创建虚拟网络和子网。安装 Azure 网络 NuGet 包。如果使用的是现有网络和子网，则此步骤是可选的。

VirtualNetwork vnet = new VirtualNetwork(name: vnetName) 
   { 
        AddressSpace = new AddressSpace 
           { 
                AddressPrefixes = new List<string> { "10.0.0.0/16" } 
           }, 
                Subnets = new List<Subnet> 
                { 
                    new Subnet(name: subnetName) 
                    { 
                        AddressPrefix = "10.0.0.0/24" 
                    } 
                }, 
                Location = m_location 
           }; 
m_NrpClient.VirtualNetworks.CreateOrUpdate(resourceGroupName, “ContosoVNet”, vnet);

创建公共 IP 地址，并设置公共 IP 地址的 DNS 标签属性。云服务（外延支持）仅支持基本 SKU 公共 IP 地址。标准 SKU 公共 IP 地址不适用于云服务（外延支持）。

如果使用静态 IP 地址，则必须将其引用为配置 (.cscfg) 文件中的保留 IP 地址。

 PublicIPAddress publicIPAddressParams = new PublicIPAddress(name: “ContosIp”) 
    { 
         Location = m_location, 
         PublicIPAllocationMethod = IPAllocationMethod.Dynamic, 
         DnsSettings = new PublicIPAddressDnsSettings() 
            { 
                 DomainNameLabel = “contosoappdns” 
            } 
    }; 
 PublicIPAddress publicIpAddress = m_NrpClient.PublicIPAddresses.CreateOrUpdate(resourceGroupName, publicIPAddressName, publicIPAddressParams);

创建网络配置文件对象，并将公共 IP 地址与负载均衡器的前端相关联。 Azure 平台会自动创建与部署位于同一订阅的“经典”SKU 负载均衡器资源。负载均衡器资源在 Azure 资源管理器中是只读的。只能通过云服务（外延支持）配置 (.cscfg) 文件和定义 (.csdef) 文件更新资源。

LoadBalancerFrontendIPConfiguration feipConfiguration = new LoadBalancerFrontendIPConfiguration() 
    { 
        Name = “ContosoFe”, 
        Properties = new LoadBalancerFrontendIPConfigurationProperties() 
            { 
            PublicIPAddress = new CM.SubResource() 
                { 
                    Id = $"/subscriptions/{m_subId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/publicIPAddresses/{publicIPAddressName}", 
                } 
            } 
    }; 

CloudServiceNetworkProfile cloudServiceNetworkProfile = new CloudServiceNetworkProfile() 
    { 
        LoadBalancerConfigurations = new List<LoadBalancerConfiguration>() 
            { 
                new LoadBalancerConfiguration() 
                   { 
                    Name  = 'ContosoLB', 
                    Properties = new LoadBalancerConfigurationProperties() 
                        { 
                        FrontendIPConfigurations = new List<LoadBalancerFrontendIPConfiguration>() 
                            { 
                            feipConfig 
                            } 
                        } 
                    } 
            } 
    };

创建密钥保管库。此密钥保管库可存储与云服务（外延支持）角色关联的证书。该密钥保管库必须位于云服务（外延支持）资源所在的同一区域和订阅中，并且名称必须唯一。有关详细信息，请查看在云服务（外延支持）中使用证书。
```
New-AzKeyVault -Name "ContosKeyVault” -ResourceGroupName “ContosoOrg” -Location “East US”
```

更新密钥保管库的访问策略，并向你的用户帐户授予证书权限：

Set-AzKeyVaultAccessPolicy -VaultName 'ContosKeyVault' -ResourceGroupName 'ContosoOrg' -UserPrincipalName 'user@domain.com' -PermissionsToCertificates create,get,list,delete

或者，通过对象 ID（可通过运行 Get-AzADUser 来获取）设置访问策略：

Set-AzKeyVaultAccessPolicy -VaultName 'ContosKeyVault' -ResourceGroupName 'ContosOrg' -ObjectId 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' -PermissionsToCertificates create,get,list,delete

以下示例将自签名证书添加到了密钥保管库。必须在云服务（扩展支持）角色的配置 (.cscfg) 文件中添加证书指纹。

$Policy = New-AzKeyVaultCertificatePolicy -SecretContentType "application/x-pkcs12" - SubjectName "CN=contoso.com" -IssuerName "Self" -ValidityInMonths 6 -ReuseKeyOnRenewal 
Add-AzKeyVaultCertificate -VaultName "ContosKeyVault" -Name "ContosCert" -CertificatePolicy $Policy

创建 OS 配置文件对象。 OS 配置文件指定与云服务（外延支持）角色关联的证书。使用在上一步中创建的同一证书。

CloudServiceOsProfile cloudServiceOsProfile = 
    new CloudServiceOsProfile 
       { 
            Secrets = new List<CloudServiceVaultSecretGroup> 
               { 
                    New CloudServiceVaultSecretGroup { 
                    SourceVault = <sourceVault>, 
                    VaultCertificates = <vaultCertificates> 
                    } 
               } 
       };

创建角色配置文件对象。角色配置文件定义 SKU 的角色特定的属性，例如名称、容量和层级。

本示例定义了两个角色：ContosoFrontend 和 ContosoBackend。角色配置文件信息必须与配置 (.cscfg) 文件和定义 (.cscfg) 文件中定义的角色匹配。

CloudServiceRoleProfile cloudServiceRoleProfile = new CloudServiceRoleProfile()
   {
        Roles = new List<CloudServiceRoleProfileProperties>();

            // foreach role in cloudService
            roles.Add(new CloudServiceRoleProfileProperties()
                {
                    Name = 'ContosoFrontend',
                    Sku = new CloudServiceRoleSku
                    {
                        Name = 'Standard_D1_v2',
                        Capacity = 2,
                        Tier = 'Standard'
                    }
                );

            roles.Add(new CloudServiceRoleProfileProperties()
                {
                    Name = 'ContosoBackend',
                    Sku = new CloudServiceRoleSku
                    {
                        Name = 'Standard_D1_v2',
                        Capacity = 2,
                        Tier = 'Standard'
                    }
                );

                }
                }

（可选）创建要添加到云服务（外延支持）部署的扩展配置文件对象。此示例添加了远程桌面协议 (RDP) 扩展：

string rdpExtensionPublicConfig = "<PublicConfig>" +
    "<UserName>adminRdpTest</UserName>" +
    "<Expiration>2021-10-27T23:59:59</Expiration>" +
    "</PublicConfig>";
    string rdpExtensionPrivateConfig = "<PrivateConfig>" +
    "<Password>VsmrdpTest!</Password>" +
    "</PrivateConfig>";

    Extension rdpExtension = new Extension
            {
                Name = name,
                Properties = new CloudServiceExtensionProperties
                {
                    Publisher = "Microsoft.Windows.Azure.Extensions",
                    Type = "RDP",
                    TypeHandlerVersion = "1.2.1",
                    AutoUpgradeMinorVersion = true,
                    Settings = rdpExtensionPublicConfig,
                    ProtectedSettings = rdpExtensionPrivateConfig,
                    RolesAppliedTo = [“*”],
                }
            };

CloudServiceExtensionProfile cloudServiceExtensionProfile = new CloudServiceExtensionProfile
    {
        Extensions = rdpExtension
    };

创建云服务（外延支持）部署：

CloudService cloudService = new CloudService
    {
        Properties = new CloudServiceProperties
            {
                RoleProfile = cloudServiceRoleProfile
                Configuration = < Add Cscfg xml content here>,
                // ConfigurationUrl = <Add your configuration URL here>,
                PackageUrl = <Add cspkg SAS url here>,
                ExtensionProfile = cloudServiceExtensionProfile,
                OsProfile= cloudServiceOsProfile,
                NetworkProfile = cloudServiceNetworkProfile,
                UpgradeMode = 'Auto'
            },
                Location = m_location
            };

CloudService createOrUpdateResponse = m_CrpClient.CloudServices.CreateOrUpdate(“ContosOrg”, “ContosoCS”, cloudService);
