仅使用Powershell列出EC2的名称

Question

I set an a variable $ec2-instance = GetEC2Instance and this returns something like...

GroupNames : {} Groups : {} Instances : {somekey} OwnerId : 11111111 RequesterId : ReservationId : r-111111111

What I'm trying to do is list just the name of the EC2 instance. I know, "name" is a tag but not sure how to capture in PowerShell.

Get-EC2Instance returns a list of Instances, you can iterate over that list and grab the value of the Name tag like this:

ForEach($i in (Get-EC2Instance).Instances) {
   ($i.Tags | ? { $_.Key -eq "Name"} | select -expand Value)
}
