.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 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 WindowsServer2022 -Region us-east-1).ImageId ami-041114ddee4a98333 Above finds the latest Windows Server 2016 Base AMI in us-east-1 region .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).ImageId -KeyPair MyKeyPair This launches an instance in the us-east-1 region getting the latest AMI for Windows Serve 2016 in that region. .OUTPUTS Image (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 { [OutputType([Amazon.Route53.Model.ChangeInfo])] [CmdletBinding(DefaultParameterSetName = 'Windows')] Param( [Parameter(Position = 0)] #[ValidatePattern('WindowsServer2(0(1(2R2|6|9)|22)|[12]H2)|Ubuntu(18|2[02])\.04|AmazonLinux2(02\d)?')] [ValidateSet( "WindowsServer22H2", "WindowsServer21H2", "WindowsServer2022", "WindowsServer2019", "WindowsServer2016", "WindowsServer2012R2", "Ubuntu22.04", "Ubuntu20.04", "Ubuntu18.04", "AmazonLinux2", "AmazonLinux2022", "AmazonLinux2023", "AmazonLinux2025", "AmazonLinux2027", "AmazonLinux2NetCore" )] [string] $OsVersion = "WindowsServer2022", [ValidateSet("2022","2019", "2017", "2016", "2014")] [Parameter(ParameterSetName='SQL')] [string] $SqlVersion, [Parameter(ParameterSetName='SQL')] [ValidateSet("Express", "Web", "Standard", "Enterprise")] [string] $SqlEdition = "Standard", [switch] $Core, [Parameter(ParameterSetName='Containers')] [switch] $Containers, [Parameter(ParameterSetName='Ecs')] [switch] $EcsOptimized, [ValidateScript( { @((Get-AWSRegion).Region) })] [string] $Region, # The CPU Architecture to use.
