We are taging our AWS instances, I will like to retrieve a list of ALL our instances (ELB, S3, EC2, Security Groups) by TAG reference. for instance we consistently TAG our resources with something like this: { "Key": "Project", "Value": "bananas" },
How can we obtain trough power-shell a list of ALL our resources that contain the TAG Project value "bananas"?
I was able to get all my EC2s using the below script:
$instance = Get-EC2Instance
-Filter @( @{name='tag:Project'; values="bananas"};
@{name='instance-state-code'; values = 16} )
| Select-Object -ExpandProperty instances #Get instance ID ignoring any terminated instances
$instance | Export-CSV "C:\ec2.csv"
But I'm not sure how to obtain all my tagged resources using one script.
Check out the AWS Resource Groups Tagging API cmdlets -- these are relatively new, so you may have to update your AWS Tools for PowerShell to the latest version to be able to use them.
The example below calls Get-RGTResource for the tag Key=Project, Value=Bananas, and filters the response to all ResourceARNs that were retrieved. The ResourceARN is a unique identifier for each AWS resource, and you can use these as a starting point to call out to other AWS services to get more details about each associated resource.
(Get-RGTResource -TagFilter @{Key="Project"; Values = @("bananas")}).ResourceARN
