如何使用 Azure 资源管理器 select 最近的 Ubuntu 14.04 LTS 映像？
How select the most recent Ubuntu 14.04 LTS image using Azure Resource Manager?
创建经典 Azure VM 时，我可以使用此 PowerShell 找到最新的 Ubuntu 14.04 映像：
Get-AzureVMImage | where { $_.ImageFamily -eq "Ubuntu Server 14.04 LTS" } | sort PublishedDate -Descending | select -First 1
目前这给了我 14.04.5-LTS，这是完美的。
如何使用 Resource Manager PowerShell commandlet 执行相同的操作？我能算出的最接近的是：
Get-AzureRMVMImageSku -Location "East US" -Publisher "Canonical" -Offer "UbuntuServer"
哪个returns
Skus Offer PublisherName Location Id

我想我可以 grep 出最后一个 ^14.04(.\d+)?-LTS$，但我不喜欢依赖保持不变的命名约定。 classic 的 ImageFamily 和 PublishedDate 在哪里？
在ARM模块中，图片没有PublishedDate，我们可以用sku列出最新的：
Get-AzureRmVMImageSku -Location "East Us" -PublisherName "canonical" -Offer "UbuntuServer" | ?{($_.skus -like '14.04.*-lts') -and ($_.skus -notlike '14.04.*-da*')} | Sort-Object -Descending skus | select -First 1
$a = (Get-AzureRmVMImageSku -Location "East Us" -PublisherName "canonical" -Offer "UbuntuServer" | ?{($_.skus -like '14.04.*-lts') -and ($_.skus -notlike '14.04.*-da*')} | Sort-Object skus).skus
$b = ([int[]](($a -split '-' -split 'LTS' -split '14.04.') | sort -Descending)) | select -Unique | select -First 1
$c = '14.04.'+$b+'-LTS'
Get-AzureRmVMImageSku -Location "East Us" -PublisherName "canonical" -Offer "UbuntuServer" | ?{($_.skus -eq $c)}
更新：
你是对的，依赖命名方案是个坏主意。我发现在 Azure ARM 模块中，我们可以使用 Get-AzureRmVMImage |排序对象-降序-属性 PublishedDate:
$ossku = "16.04-beta"
Get-AzureRmVMImage -Location "East Us" -PublisherName 'canonical' -Offer 'UbuntuServer' -Skus $osSKU | Sort-Object -Descending -Property PublishedDate
