Using service-linked roles for Amazon MQ - Amazon MQ
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Using service-linked roles for Amazon MQ

Amazon MQ uses Amazon Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to Amazon MQ. Service-linked roles are predefined by Amazon MQ and include all the permissions that the service requires to call other Amazon services on your behalf.

A service-linked role makes setting up Amazon MQ easier because you don’t have to manually add the necessary permissions. Amazon MQ defines the permissions of its service-linked roles, and unless defined otherwise, only Amazon MQ can assume its roles. The defined permissions include the trust policy and the permissions policy, and that permissions policy cannot be attached to any other IAM entity.

You can delete a service-linked role only after first deleting their related resources. This protects your Amazon MQ resources because you can't inadvertently remove permission to access the resources.

For information about other services that support service-linked roles, see Amazon services that work with IAM and look for the services that have Yes in the Service-Linked Role column. Choose a Yes with a link to view the service-linked role documentation for that service.

Service-linked role permissions for Amazon MQ

Amazon MQ uses the service-linked role named AWSServiceRoleForAmazonMQ – Amazon MQ uses this service-linked role to call Amazon services on your behalf.

The AWSServiceRoleForAmazonMQ service-linked role trusts the following services to assume the role:

  • mq.amazonaws.com

Amazon MQ uses the permission policy AmazonMQServiceRolePolicy, which is attached to the AWSServiceRoleForAmazonMQ service-linked role, to complete the following actions on the specified resources:

  • Action: ec2:CreateVpcEndpoint on the vpc resource.

  • Action: ec2:CreateVpcEndpoint on the subnet resource.

  • Action: ec2:CreateVpcEndpoint on the security-group resource.

  • Action: ec2:CreateVpcEndpoint on the vpc-endpoint resource.

  • Action: ec2:DescribeVpcEndpoints on the vpc resource.

  • Action: ec2:DescribeVpcEndpoints on the subnet resource.

  • Action: ec2:CreateTags on the vpc-endpoint resource.

  • Action: logs:PutLogEvents on the log-group resource.

  • Action: logs:DescribeLogStreams on the log-group resource.

  • Action: logs:DescribeLogGroups on the log-group resource.

  • Action: CreateLogStream on the log-group resource.

  • Action: CreateLogGroup on the log-group resource.

When you create an Amazon MQ for RabbitMQ broker, the AmazonMQServiceRolePolicy permission policy allows Amazon MQ to perform the following tasks on your behalf.

  • Create a Amazon VPC endpoint for the broker using the Amazon VPC, subnet, and security-group you provide. You can use the endpoint created for your broker to connect to the broker via the RabbitMQ management console, the management API, or programatically.

  • Create log groups, and publish broker logs to Amazon CloudWatch Logs.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "ec2:DescribeVpcEndpoints" ], "Resource": "*" }, { "Effect": "Allow", "Action": [ "ec2:CreateVpcEndpoint" ], "Resource": [ "arn:aws:ec2:*:*:vpc/*", "arn:aws:ec2:*:*:subnet/*", "arn:aws:ec2:*:*:security-group/*" ] }, { "Effect": "Allow", "Action": [ "ec2:CreateVpcEndpoint" ], "Resource": [ "arn:aws:ec2:*:*:vpc-endpoint/*" ], "Condition": { "StringEquals": { "aws:RequestTag/AMQManaged": "true" } } }, { "Effect": "Allow", "Action": [ "ec2:CreateTags" ], "Resource": "arn:aws:ec2:*:*:vpc-endpoint/*", "Condition": { "StringEquals": { "ec2:CreateAction": "CreateVpcEndpoint" } } }, { "Effect": "Allow", "Action": [ "ec2:DeleteVpcEndpoints" ], "Resource": "arn:aws:ec2:*:*:vpc-endpoint/*", "Condition": { "StringEquals": { "ec2:ResourceTag/AMQManaged": "true" } } }, { "Effect": "Allow", "Action": [ "logs:PutLogEvents", "logs:DescribeLogStreams", "logs:DescribeLogGroups", "logs:CreateLogStream", "logs:CreateLogGroup" ], "Resource": [ "arn:aws:logs:*:*:log-group:/aws/amazonmq/*" ] } ] }

You must configure permissions to allow an IAM entity (such as a user, group, or role) to create, edit, or delete a service-linked role. For more information, see Service-Linked Role Permissions in the IAM User Guide.

Creating a service-linked role for Amazon MQ

You don't need to manually create a service-linked role. When you first create a broker, Amazon MQ creates a service-linked role to call Amazon services on your behalf. All subsequent brokers that you create will use the same role and no new role is created.

Important

This service-linked role can appear in your account if you completed an action in another service that uses the features supported by this role. To learn more, see A New Role Appeared in My IAM Account.

If you delete this service-linked role, and then need to create it again, you can use the same process to recreate the role in your account.

You can also use the IAM console to create a service-linked role with the Amazon MQ use case. In the Amazon CLI or the Amazon API, create a service-linked role with the mq.amazonaws.com service name. For more information, see Creating a service-linked role in the IAM User Guide. If you delete this service-linked role, you can use this same process to create the role again.

Editing a service-linked role for Amazon MQ

Amazon MQ does not allow you to edit the AWSServiceRoleForAmazonMQ service-linked role. However, you can edit the description of the role using IAM. For more information, see Editing a service-linked role in the IAM User Guide.

Deleting a service-linked role for Amazon MQ

If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way you don’t have an unused entity that is not actively monitored or maintained. However, you must clean up the resources for your service-linked role before you can manually delete it.

Note

If the Amazon MQ service is using the role when you try to delete the resources, then the deletion might fail. If that happens, wait for a few minutes and try the operation again.

To delete Amazon MQ resources used by the AWSServiceRoleForAmazonMQ
  • Delete your Amazon MQ brokers using the Amazon Web Services Management Console, Amazon MQ CLI, or Amazon MQ API. For more information about deleting brokers, see Deleting a broker.

To manually delete the service-linked role using IAM

Use the IAM console, the Amazon CLI, or the Amazon API to delete the AWSServiceRoleForAmazonMQ service-linked role. For more information, see Deleting a Service-Linked Role in the IAM User Guide.
