azure - 如何使用 Azure 资源管理器选择最新的 Ubuntu 14.04 LTS 镜像？

Question

创建经典 Azure VM 时，我可以使用此 PowerShell 找到最新的 Ubuntu 14.04 镜像:

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。

如何使用资源管理器 PowerShell commandlet 执行相同操作？我能算出的最接近的是:

Get-AzureRMVMImageSku -Location "East US" -Publisher "Canonical" -Offer "UbuntuServer"

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？

Answer 1

在ARM模块中，图像没有PublishedDate，我们可以使用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，依赖命名方案是一个坏主意。我发现在Azure ARM模块中，我们可以使用Get-AzureRmVMImage |排序对象-降序-属性发布日期:

$ossku = "16.04-beta"
Get-AzureRmVMImage -Location "East Us" -PublisherName 'canonical' -Offer 'UbuntuServer' -Skus $osSKU | Sort-Object -Descending -Property PublishedDate
