        Position = 0,
        Mandatory=$false, 
        ValueFromPipeline=$true,
        ValueFromPipelineByPropertyName=$true)]
        [string]$ContainerName = "microsoft/*"
    )
    $i = 1
    $FoundContainer = docker search --format "{{.Name}}" $ContainerName 
    $FoundContainer | %{
        "$i. $_"
        $i++ 
    }
    IF ($FoundContainer.count -gt 1){
        $Select = Read-Host "Please make a selection"
        return $FoundContainer[$($Select-1)]
    }ELSE{
        return $FoundContainer[0]
    }
}
