Azure Powershell cmdlets for 1.7, June 2012: what's happened to Get-OperationStatus?

Question

The new Powershell cmdlets (documented here: http://msdn.microsoft.com/en-us/library/windowsazure/jj152841) look lovely, but there's one that appears missing:

Get-OperationStatus -WaitToComplete

Without this my Azure operations (e.g. Set-AzureDeployment) don't wait for completion.

This makes it hard to know when e.g. a staging instance is running before doing a VIP swap.

Are there any alternatives?

Answer 1

So, after investigation, my initial supposition was partly wrong: calls to the new Powershell cmdlets do wait for successful completion, except for Set-AzureDeployment -newStatus "Running".

This is good, as we no longer need to have calls to Get-OperationStatus scattered through the script; it's bad, though, as Set-AzureDeployment leaves the deployment spinning up.

We can call Get-AzureDeployment, though, and iterate through the RoleInstanceList to figure out what's going on. Like so:

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."
}
