OpenOps provides infrastructure-as-code templates to create IAM roles in your AWS account with the necessary permissions to connect to your AWS resources. Two roles are available: the OpenOpsApp role for running workflows, and the Benchmark role for running cost optimization benchmarks.

​
OpenOpsApp Role

Creates the OpenOpsApp role with permissions to run workflows from the OpenOps template catalog. The template contains all the read permissions needed to execute all templates in our library; you can still restrict the scope to the permissions needed for the templates you are actually running. Write permissions are optional and only needed if you want to apply remediation actions directly to cloud resources. The role can be created with either AWS CloudFormation or Terraform - both produce the same role and permissions.
Besides the IAM role, the template by default also sets up cost management resources: it creates an S3 bucket (openops-cur-<account-id>) and a Cost and Usage Report definition that continuously exports billing reports to that bucket.This is why the role must be created in the us-east-1 region as CUR is only available there. If you don’t want these resources, disable the CostUsageReport parameter (CloudFormation) or set cost_usage_report = false (Terraform); the template then creates IAM resources only and can be deployed in any region.

Using CloudFormation

Create OpenOpsApp stack | Download template Parameters: AWS account ID (required), CostUsageReport (optional, default true), permission sets (optional)
  1. Click the Create OpenOpsApp stack link above.
  2. On the Specify stack details page, enter the required parameters, then click Next.
  3. On the Configure stack options page, click Next.
  4. On the Review and create page, scroll down to the Capabilities section and acknowledge the creation of IAM roles: Capabilities
  5. Click Submit. The stack will be created with the configured permissions.

​
Using Terraform

Download template | View on GitHub Variables: aws_account_id (required), external_id (optional), role_name (optional, default OpenOpsApp), cost_usage_report (optional, default true), permission toggles (optional) Download the template into an empty directory and apply it:
Replace <account-id> with the ID of the AWS account where your OpenOps environment is deployed - the account that will assume the role. The template can also be consumed as a Terraform module, which makes it easy to roll the role out across many AWS accounts. See the template’s README for details.

​
Benchmark Role Stack

Creates a read-only OpenOpsBenchmarkRole specifically for running AWS cost optimization benchmarks. Includes Compute Optimizer permissions, resource read access (EC2, RDS, ELB, DynamoDB, CloudWatch, Cost Explorer, CloudTrail), and Pricing API access. This role is available as a CloudFormation template. Create Benchmark stack | Download template | View on GitHub Parameters: TrustedAccountId (required), ExternalId (optional, recommended for security) To install, click the Create Benchmark stack link above and follow the same steps as for the OpenOpsApp stack. The Benchmark stack can be created in any region.

​
Modification

You’re welcome to download any of the templates and modify specific permissions according to your needs. Notice that some AWS components in OpenOps workflows may not function properly as a result.
