.Synopsis Find the latest AWS EC2 AMI based on search critera .DESCRIPTION Outputs only the image ID of the latest AWS EC2 AMI based on option you specficy such as Windows version, SQL verison and SQL Edition or Amazon Linux(2) or Ubuntu Supports Core and Container based AMIS and Windows version 2003, 2008, 2008R2, 2012, 2012 R2, 2016, 1709, 1803, 1809 and 2019 It does this mostly by querying the SSM public paramter store, so the user that is running this must have the AWS PowerShell Module installed and configured as well permission to the ssm:describeparameter action .EXAMPLE PS C:\> Get-CmEc2ImageId -OsVersion WindowsServer2016 -Region us-east-1 ami-041114ddee4a98333 Above finds the latest Windows Server 2016 Base AMI in us-east-1 region .EXAMPLE PS C:\> Get-CmEc2ImageId -OsVersion WindowsServer2012R2 -SqlVersion 2008R2 WARNING: SQL Server 2008 R2 and 2012 only supported on Windows Server 2008R2 and 2012, switching to Windows 2012 ami-0193fd36c14f87865 Here SQL server 2008R2 is not supported on Windows 2012 R2 and it has automatically changed the OS to the latest one that supports this SQL version .EXAMPLE PS C:\> Get-CmEc2ImageId -OsVersion 2019 -Core -Containers -Region us-east-1 ami-0f3d4a916972fd1ac Here we specify we want Windows Server 2019 Core edition with Containers in the us-east-1 region .EXAMPLE PS C:\> New-EC2Instance -Region us-east-1 -Subnet subnet-97654567890 -ImageId (Get-CmEc2ImageId -OsVersion WindowsServer2016 -Region us-east-1) -KeyPair MyKeyPair This launches an instance in the us-east-1 region getting the latest AMI for Windows Serve 2016 in that region. .INPUTS Inputs to this cmdlet (if any) .OUTPUTS ImageId (String) .NOTES General notes .COMPONENT The component this cmdlet belongs to .ROLE The role this cmdlet belongs to the CMAWS Module .FUNCTIONALITY The functionality that best describes this cmdlet #> Function Get-CmEc2ImageId { [CmdletBinding(DefaultParameterSetName='Base')] Param( [Parameter(Position=0)] #[ValidatePattern('(WindowsServer)?(180(3|9)|1709|20(03|(08|12)(R2)?|16|19))|Ubuntu1(6|8)\.04|AmazonLinux2?')] [ValidateSet("WindowsServer1809", "WindowsServer1803", "WindowsServer1709", "WindowsServer2019", "WindowsServer2016", "WindowsServer2012R2", "WindowsServer2012", "WindowsServer2008R2", "WindowsServer2008", "WindowsServer2003", "1809", "1803", "1709", "2019", "2016", "2012R2", "2012", "2008R2", "2008", "2003", "Ubuntu16.04", "Ubuntu18.04", "AmazonLinux", "AmazonLinux2")] [string] $OsVersion="2012R2", [ValidateSet("2019","2017","2016","2014","2012","2008R2","2008","2005")] [string] $SqlVersion, [ValidateSet("Express", "Web","Standard","Enterprise")] [string] $SqlEdition = "Standard", [switch] $Core, [switch] $Containers, [switch] $NoSwitching, #[ValidateScript({@((Get-AWSRegion).Region;"")})] [string] $Region, [ValidateSet( "Chinese_Traditional", "Chinese_Simplified", "Czech", "Dutch", "English", "French", "German", "Hungarian", "Korean", "Japanese", "Polish", "Portuguese_Brazil", "Russian", "Spanish", "Swedish", "Turkish" )] [string] $Language = "English" ) $ErrorActionPreference = "Stop" if(!$Region){$Region = (Get-DefaultAWSRegion).Region} If ($OsVersion -like "WindowsServer*"){ $OsVersion = $OsVersion.Substring(13) $WindowsServer = $True } $Base = $True If ($OsVersion -match '(180(3|9)|1709|20(03|(08|12)(R2)?|16|19))'){ if ((Get-Date) -lt $([datetime]"2019/04")) { $LatestStable = "1809","2016" } else { $LatestStable = "2019","2019" } if ($OsVersion -match '(1709|180(3|9))'){$Core = $True} if ($Core -and $OsVersion -notmatch '1709|180(3|9)|20((08|12)R2|16|19)') { Write-Warning "Core AMIs only available for Windows Server 2008R2, 2012R2, 2016, 1709, 1803, 1809 and 2019, Switching to Windows Server $($LatestStable[0])" $OsVersion = $LatestStable[0] } if ($Containers) { $Base = $False if ($OsVersion -notmatch '1709|180(3|9)|201(6|9)') { Write-Warning "Container AMIs only available for Windows Server 2016, 1709, 1803, 1809 and 2019, Switching to Windows Server $($LatestStable[1])" $OsVersion = $LatestStable[1] } } if ($SqlVersion) { $Base = $False If ($Core -and $OsVersion -ne 2016 -and $SqlVersion ) { Write-Warning "SQL only avaialable on Core Editions of Windows Server 2016, Switching to Full";
