使用PowerShell部署Service Fabric。错误-> Get-ServiceFabricClusterManifest：集群连接实例为空。

14

我正在尝试使用PowerShell将Service Fabric应用程序发布到Azure。我想连接到集群，然后调用脚本“Deploy-FabricApplication.ps1”（在Visual Studio中创建新项目时生成的脚本之一）

为此，我创建了一个新的脚本文件，负责连接到集群，然后从同一个脚本文件中调用“Deploy-FabricApplication.ps1”。

启动我的脚本后，我得到以下错误：

Get-ServiceFabricClusterManifest : Cluster connection instance is null
At C:\Program Files\Microsoft SDKs\Service Fabric\Tools\PSModule\ServiceFabricSDK\Publish-UpgradedServiceFabricApplication.ps1:116 char:28
+     $clusterManifestText = Get-ServiceFabricClusterManifest
+                            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : ResourceUnavailable: (:) [Get-ServiceFabricClusterManifest], NullReferenceException
+ FullyQualifiedErrorId : GetClusterConnectionErrorId,Microsoft.ServiceFabric.Powershell.GetClusterManifest

在连接脚本和Deploy-FabricApplication.ps1中，我调用了“Test-ServiceFabricClusterConnection”，在这两个脚本中它都返回True。此外，在这两种情况下，我也调用了“Get-ServiceFabricClusterManifest”，并且都返回给我清单。但是，当我将“Test-ServiceFabricClusterConnection”添加到“Publish-UpgradedServiceFabricApplication.ps1”时，它返回了与之前提到的相同错误，但是针对“Test-ServiceFabricClusterConnection”的调用。

连接脚本的代码:

Param
(
    [String]
    $PublishProfileFile,

    [String]
    $ApplicationPackagePath,

    [Switch]
    $DeployOnly,

    [Boolean]
    $UnregisterUnusedApplicationVersionsAfterUpgrade,

    [String]
    [ValidateSet('None', 'ForceUpgrade', 'VetoUpgrade')]
    $OverrideUpgradeBehavior = 'None',

    [String]
    [ValidateSet('Never','Always','SameAppTypeAndVersion')]
    $OverwriteBehavior = 'Never',

    [Switch]
    $SkipPackageValidation,

    [String]
    $ConnectionEndpoint,

    [String]
    $ServerCertThumbprint,

    [String]
    $FindType,

    [String]
    $FindValue,

    [String]
    $StoreLocation,

    [String]
    $StoreName
)

$connectArgs = @{ ConnectionEndpoint = $ConnectionEndpoint;  X509Credential = $True;  StoreLocation = $StoreLocation;  StoreName = $StoreName;  ServerCertThumbprint = $ServerCertThumbprint; FindType = $FindType;  FindValue = $FindValue }

try
{
    Connect-ServiceFabricCluster @connectArgs;
    $connection = Get-ServiceFabricClusterConnection;
    Write-Host $connection;
    $m = Get-ServiceFabricClusterManifest
    Write-Host $m;
}
catch [System.Fabric.FabricObjectClosedException]
{
    Write-Warning "Service Fabric cluster may not be connected."
    throw
}

.\Deploy-FabricApplication.ps1 -PublishProfileFile $PublishProfileFile -ApplicationPackagePath $ApplicationPackagePath -OverrideUpgradeBehavior $OverrideUpgradeBehavior -OverwriteBehavior $OverwriteBehavior -DeployOnly:$DeployOnly -UnregisterUnusedApplicationVersionsAfterUpgrade:$UnregisterUnusedApplicationVersionsAfterUpgrade -UseExistingClusterConnection:$true -SkipPackageValidation:$SkipPackageValidation

总之，我不知道如何连接到集群并在Deploy-FabricApplication.ps1中使用它。谢谢帮助。

调用Connect-ServiceFabricCluster时，会设置本地的$clusterConnection变量。然后，一些SDK脚本期望该变量被设置，但由于您在不同的作用域中执行脚本，所以这个本地变量对它们不可用。

您可以点运行调用Deploy-FabricApplication.ps1。

. .\Deploy-FabricApplication.ps1 -PublishProfileFile $PublishProfileFile -ApplicationPackagePath $ApplicationPackagePath -OverrideUpgradeBehavior $OverrideUpgradeBehavior -OverwriteBehavior $OverwriteBehavior -DeployOnly:$DeployOnly -UnregisterUnusedApplicationVersionsAfterUpgrade:$UnregisterUnusedApplicationVersionsAfterUpgrade -UseExistingClusterConnection:$true -SkipPackageValidation:$SkipPackageValidation

或者创建一个$global:clusterConnection变量，其中包含本地的$clusterConnection变量。

$global:clusterConnection = $clusterConnection
