azure - 适用于 1.7 的 Azure Powershell cmdlet，2012 年 6 月：Get-OperationStatus 发生了什么？

Question

新的 Powershell cmdlet（在此处记录：http: //msdn.microsoft.com/en-us/library/windowsazure/jj152841）看起来很可爱，但似乎缺少一个：

Get-OperationStatus -WaitToComplete

没有这个我的 Azure 操作（例如Set-AzureDeployment）不要等待完成。

这使得在进行 VIP 交换之前很难知道登台实例何时运行。

有没有其他选择？

Answer 1

因此，经过调查，我最初的假设部分错误：对新 Powershell cmdlet 的调用确实会等待成功完成，但.Set-AzureDeployment -newStatus "Running"

这很好，因为我们不再需要Get-OperationStatus分散在脚本中的调用；但是，这很糟糕，因为Set-AzureDeployment会使部署旋转。

不过，我们可以调用Get-AzureDeployment，并遍历RoleInstanceList以找出发生了什么。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."
}

Answer 2

但是有一个似乎不见了

如果不支持，请寻找替代方案。例如，请直接使用 REST API 而不是使用 PowerShell。REST API 允许我们跟踪异步请求：http: //msdn.microsoft.com/en-us/library/windowsazure/ee460791。
