Setting up Automation
To set up Automation, a capability of AWS Systems Manager, you must verify user access to the Automation service and situationally configure roles so that the service can perform actions on your resources. We also recommend that you opt in to the adaptive concurrency mode in your Automation preferences. Adaptive concurrency automatically scales your automation quota to meet your needs. For more information, see Allowing Automation to adapt to your concurrency needs.
To ensure proper access to AWS Systems Manager Automation, review the following user and service role requirements.
Verifying user access for runbooks
Verify that you have permission to use runbooks. If your user, group, or role is
assigned administrator permissions, then you have access to Systems Manager Automation. If you
don't have administrator permissions, then an administrator must give you permission
by assigning the AmazonSSMFullAccess managed policy, or a policy that
provides comparable permissions, to your user, group, or role.
Important
The IAM policy AmazonSSMFullAccess grants permissions to Systems Manager
actions. However, some runbooks require permissions to other services, such as
the runbook AWS-ReleaseElasticIP, which requires IAM permissions
for ec2:ReleaseAddress. Therefore, you must review the actions
taken in a runbook to ensure your user, group, or role is assigned the necessary
permissions to perform the actions included in the runbook.
Configuring a service role (assume role) access for automations
Automations can be initiated under the context of a service role (or assume role). This allows the service to perform actions on your behalf. If you don't specify an assume role, Automation uses the context of the user who invoked the automation.
However, the following situations require that you specify a service role for Automation:
-
When you want to restrict a user's permissions on a resource, but you want the user to run an automation that requires elevated permissions. In this scenario, you can create a service role with elevated permissions and allow the user to run the automation.
-
When you create a Systems Manager State Manager association that runs a runbook.
-
When you have operations that you expect to run longer than 12 hours.
-
When you're running a runbook not owned by Amazon that uses the
aws:executeScriptaction to call an AWS API operation or to act on an AWS resource. For information, see Permissions for using runbooks.
If you need to create a service role for Automation, you can use one of the following methods.
