适用于1.7的Azure Powershell cmdlet，2012年6月: what's happened to Get-OperationStatus?

新的Powershell cmdlet(在此处记录:http://msdn.microsoft.com/en-us/library/windowsazure/jj152841)看起来很可爱，但是其中一个似乎缺少:
Get-OperationStatus -WaitToComplete
没有这个，我的Azure操作(例如Set-AzureDeployment)就不会等待完成。

这使得很难知道何时在执行VIP交换之前，正在运行一个登台实例。

还有其他选择吗？

最佳答案

因此，经过调查，我最初的假设在某种程度上是错误的:对新Powershell cmdlet的调用确实需要等待成功完成，但Set-AzureDeployment -newStatus "Running"除外。

很好，因为我们不再需要通过脚本分散对Get-OperationStatus的调用；但是，这很糟糕，因为Set-AzureDeployment会使部署变得困惑起来。

我们可以调用Get-AzureDeployment，并遍历RoleInstanceList找出正在发生的事情。像这样:

function Get-StagingReady {
    $stagingStatus = Get-AzureDeployment $azureService -slot staging
    if (-not $($stagingStatus.Status -eq "Running")) {
        Write-Host $(" ... ... Staging slot status is not Running; value is " + $stagingStatus.Running)
        return $False
    }

    if (-not $stagingStatus.RoleInstanceList) {
        Write-Host " ... ... Staging slot has no instances configured yet."
        return $False
    }

    $notReady = $False

    Foreach ($roleInstance in $stagingStatus.RoleInstanceList) {
        if (-not $($roleInstance.InstanceStatus -eq "ReadyRole")) {
            Write-Host $(" ... ... ... Staging slot instance " + $roleInstance.InstanceName + " has status " + $roleInstance.InstanceStatus)
            $notReady = $True
        }
    }

    if ($notReady) {
        Write-Host " ... ... One or more instances not running."
        return $False
    }

    Write-Host " ... Staging slot ready for use."
    return $True
}


function Wait-ForStagingToBeReady {
    while ( -not $(Get-StagingReady) ) {
        Write-Host " ... ... Staging slot not ready, waiting 15 seconds for Azure to spin up instances."
        Start-Sleep -s 15
    }
}


function Start-Staging {
    Write-Host " ... Starting staging slot."

    $staging = Get-Staging $azureService
    $result = Set-AzureDeployment `
            -Status `
            -serviceName $azureService `
            -slot "Staging" `
            -newStatus "Running"

    if (-not $?) {
        Write-Host
        Write-Host "Unable to start staging slot."
        Write-Host "DEPLOY FAILED"
        Write-Host
        exit 1
    }

    Wait-ForStagingToBeReady

    Write-Host " ... Deployment in Staging slot started."
}
