Add PowerShell commands for Azure install.

[siennathesane]

It would be good if we had Azure PowerShell SDK commands for steps 1 and 2 of "Launching an Ops Manager Director Instance" under the Azure installation pages.

Here is a template script I wrote for the Azure Cloud Shell with the new PowerShell preview.

$StorageName = ""
$ResourceGroup = ""
$Location = ""
$SubscriptionName = ""
$OpsManURI = ""
# set global verbosity for all commands.
$PSDefaultParameterValues['*:Verbose'] = $true

Write-Host "Creating Resource Group and Storage Accounts"
New-AzureRmResourceGroup -Name $ResourceGroup -Location $Location
New-AzureRmStorageAccount -ResourceGroupName $ResourceGroup -AccountName $StorageName -Kind Storage -Type "Standard_LRS" -Location $Location

$Context = New-AzureStorageContext -StorageAccountName $StorageName -StorageAccountKey (Get-AzureRmStorageAccountKey -StorageAccountName $StorageName -ResourceGroupName $ResourceGroup).Value[0]

Write-Host "Creating storage containers."

$arr = @("vhds", "opsmanager", "bosh", "stemcell")

New-AzureStorageContainer -Name opsman-image -Permission Blob -Context $Context
for ($i = 0; $i -lt $arr.Length; $i++) { New-AzureStorageContainer -Name $arr[$i] -Context $Context }
New-AzureStorageTable -Name stemcells -Context $Context

Write-Host "Copying OpsMan blob."
Start-AzureStorageBlobCopy -AbsoluteUri $OpsManURI -DestContainer "opsman-image" -DestBlob "image.vhd" -DestContext $Context

while ((Get-AzureStorageBlobCopyState -Context $Context -Blob "image.vhd" -Container "opsman-image").Status -eq "Pending") { 
    Start-Sleep -Seconds 3
    Write-Host "Waiting on OpsMan Blob to finish copying" 
}

Write-Host "done."
