<a name="required-iam-permissions"></a>

The IAM security principal that you're using must have permissions to work with AWS PCS IAM roles, service linked roles, AWS CloudFormation, a VPC, and related resources. For more information, see [Identity and Access Management for AWS Parallel Computing Service](security-iam.md), and [Create a service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create-service-linked-role.html) in the *AWS Identity and Access Management User Guide*. You must complete all steps in this guide as the same user. To check the current user, run the following command: 

```
aws sts get-caller-identity
```
