Use ListGroupResources with an AWS SDK or CLI

To list all of the resources in a resource group

Example 1: The following list-resource-groups example lists all of the resources that are part of the specified resource group.

aws resource-groups list-group-resources \
    --group-name tbq-WebServer

Output:

{
    "ResourceIdentifiers": [
        {
            "ResourceArn": "arn:aws:ec2:us-west-2:123456789012:instance/i-09f77fa38c12345ab",
            "ResourceType": "AWS::EC2::Instance"
        }
    ]
}

Example 2: The following example lists all of the resources in the group that also have a 'resource-type' of the 'AWS::EC2::Instance'. :

aws resource-groups list-group-resources --group-name tbq-WebServer --filters Name=resource-type,Values=AWS::EC2::Instance

Example 1: This example lists group resources on the basis of filtered by resource type

Get-RGGroupResourceList -Filter @{Name="resource-type";Values="AWS::EC2::Instance"} -GroupName auto-yes | Select-Object -ExpandProperty ResourceIdentifiers

Output:

ResourceArn                                                     ResourceType
-----------                                                     ------------
