-EDIT 03-
我正在编辑我的问题，因为评论太小。
我终于完成了任务。我必须编辑Publish-UpgradedServiceFabricApplication来接受“ compareApplicationName”和“ compareMode”。然后它将使用那些来确定将要升级的服务列表。在完成所有应用程序升级之前，我必须小心不要取消注册ApplicationType。
对不起，但是我的法律部门不允许我发布任何实际代码，声称它是公司的IP。
-EDIT 02-
用户错误
事实证明，Get-VstsInput从线程调用时不返回任何值。因此，所有评估都是错误的，该错误被线程吞没了。
我正在重写，只是将调用线程化为Publish-UpgradedServiceFabricApplication。
-原始消息-
我有一个运行多个服务的服务结构集群。其中一些是动态创建的服务，因此在ServiceManifest.xml中未引用它们
我有一个自定义任务，可以按顺序更新动态创建的服务，但这需要几个小时。我正在尝试并行运行Publish-UpgradedServiceFabricApplication，以便可以一次运行所有升级作业。作业开始（我认为），但是任务永远不会等待它们完成才结束（从而结束PS作业）。
我尝试在作业状态上添加一个Do...While循环，但它仍会过早地结束任务。
在升级运行过程中，如何使任务保持活动状态？
-EDIT-
我觉得我需要提供一个示例，因为我的代码无法正常运行。在任务中给出以下代码：
foreach($serviceapp in $servicefabricapp){
if(-not ($serviceapp.ApplicationName.OriginalString.StartsWith("fabric:/DynamicService"))) {
Write-Host "Application '$($serviceapp.ApplicationName.OriginalString)' does not start with 'fabric:/DynamicService' -SKIPPING"
continue
}
$foundTaxReturnApp = $true
Write-Host "Starting upgrade for $($serviceapp.ApplicationName.OriginalString)"
Start-Job -ScriptBlock $upgradeScriptBlock -ArgumentList $serviceapp.ApplicationName, $applicationPackagePath, $applicationParameterFile, $publishProfile, $isUpgrade, $upgradeParameters
Start-Sleep 5
}
$jobCount = (Get-Job | Where-Object{ $_.state -eq 'Running'}).Count
Do {
Start-Sleep -Seconds 30
Write-Host "Waiting for $jobCount jobs to finish..."
$jobCount = (Get-Job | Where-Object{ $_.state -eq 'Running'}).Count
} while ($jobCount -gt 0)
Get-Job
$jobCount = (Get-Job | Where-Object{ $_.state -eq 'Running'}).Count
Write-Host "Finished waiting, $jobCount jobs running."
这是管道的输出。在“升级结构：/ DynamicService-2019OA20200131__16_21_39”与“等待0个作业完成...”之间没有时间。而且没有DynamicServices升级。

答案 0 :(得分：0)
在这种情况下，脚本可以正确执行。作业的概念是执行并继续前进。如果您想等待所有作业执行完毕后Get-Job | Wait-Job来完成作业。
如果您想执行更高级/更智能的操作，可以将其放入do-while循环中
Do {
$Job = Get-Job
if ($Job.Status -eq "Failed") {
"Fail"
Exit 1
}
Sleep 10
} Until ($Job.Status -eq "Success")
