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)
为此,我创建了新的脚本文件,负责与集群连接,然后从同一个脚本文件中调用“Deploy-FabricApplication.ps1”。
启动我的脚本后,我收到以下错误:
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“Test-ServiceFabricClusterConnection”,在两个脚本中它也在我调用“Get-ServiceFabricClusterManifest”的两个脚本中都返回True,并且在两种情况下它都返回给我清单但是当我已将“Test-ServiceFabricClusterConnection”添加到“Publish-UpgradedServiceFabricApplication.ps1”,然后它返回了与前面提到的相同的错误,但是对于“Test-ServiceFabricClusterConnection”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,

$ConnectionEndpoint,

$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
总结一下,我不知道如何建立与集群的连接,然后在Deploy-FabricApplication.ps1中使用它
感谢您的帮助

调用Connect-ServiceFabricCluster
时,设置了本地$clusterConnection
变量。然后,某些SDK脚本希望设置该变量,但由于您在不同的范围内执行您的脚本,因此该局部变量不可用。
您可以点源调用Deploy-FabricApplication.ps1
. .\Deploy-FabricApplication.ps1 -PublishProfileFile $PublishProfileFile -ApplicationPackagePath $ApplicationPackagePath -OverrideUpgradeBehavior $OverrideUpgradeBehavior -OverwriteBehavior $OverwriteBehavior -DeployOnly:$DeployOnly -UnregisterUnusedApplicationVersionsAfterUpgrade:$UnregisterUnusedApplicationVersionsAfterUpgrade -UseExistingClusterConnection:$true -SkipPackageValidation:$SkipPackageValidation
或创建一个$ global:clusterConnection变量,该变量包含本地$ clusterConnection变量
$global:clusterConnection = $clusterConnection
