我的powershell数组出了什么问题？ [英] What is wrong with my powershell array?

问题描述

$Servers = Get-EC2Tag -Region us-east-2 | ? { $_.ResourceType -eq "Instance" -and $_.Key -eq "Name" } | select -expand Value 
$a =@("$Servers,") # Name of servers to be restarted


ForEach($Servers in $a) {

 
    $instanceID = Get-EC2Instance -Region us-east-2 -Filter @{name='tag:Name'; values=$Servers} | Select -ExpandProperty instances | Select -expand InstanceId #Get instance ID

    }
    $instanceID

好​​我为什么选择在实例ID的输出上没有得到返回的instanceID？



我尝试过：



我试图将AMI Name标记放入一个数组中，然后为每个标记执行一个为每个EC2实例创建关联的AMI。



任何人都可以帮助它似乎在instanceID上没有输出错误，即使我写了Write-Host $ instanceID

Okay why do I get no returned instanceID on the output of instance ID?

What I have tried:

I have attempted to put the AMI Name tag into an array then do a for each to create the associated AMI for every EC2 Instance.

Can anyone help it seems to error on instanceID with no output even if I do Write-Host $instanceID
