To list IAM roles for the current account

The following list-roles command lists IAM roles for the current account.

aws iam list-roles

Output:

{ "Roles": [ { "Path": "/", "RoleName": "ExampleRole", "RoleId": "AROAJ52OTH4H7LEXAMPLE", "Arn": "arn:aws:iam::123456789012:role/ExampleRole", "CreateDate": "2017-09-12T19:23:36+00:00", "AssumeRolePolicyDocument": { "Version": "2012-10-17", "Statement": [ { "Sid": "", "Effect": "Allow", "Principal": { "Service": "ec2.amazonaws.com" }, "Action": "sts:AssumeRole" } ] }, "MaxSessionDuration": 3600 }, { "Path": "/example_path/", "RoleName": "ExampleRoleWithPath", "RoleId": "AROAI4QRP7UFT7EXAMPLE", "Arn": "arn:aws:iam::123456789012:role/example_path/ExampleRoleWithPath", "CreateDate": "2023-09-21T20:29:38+00:00", "AssumeRolePolicyDocument": { "Version": "2012-10-17", "Statement": [ { "Sid": "", "Effect": "Allow", "Principal": { "Service": "ec2.amazonaws.com" }, "Action": "sts:AssumeRole" } ] }, "MaxSessionDuration": 3600 } ] }

Example 1: This example retrieves a list of all of the IAM roles in the Amazon Web Services account.

Get-IAMRoleList

Example 2: This example code snippet retrieves a list of IAM roles in the Amazon account and displays them three at a time, and waits for you to press Enter between each group. It passes the Marker value from the previous call to specify where the next group should begin.

$nextMarker = $null Do { $results = Get-IAMRoleList -MaxItem 3 -Marker $nextMarker $nextMarker = $AWSHistory.LastServiceResponse.Marker $results Read-Host } while ($nextMarker -ne $null)
