Step-3: Create Role / IAM User

DigitalEx supports both types of AWS authentications,

1. Roles

2. Users

Role-based access is generally considered to be more secure than user-based access, as it allows organizations to control access to resources and functions based on defined roles and responsibilities. We recommend using roles over individual users whenever possible

Roles

1. Search IAM and Navigate to IAM dashboard

2. Click on Roles from the left menu options and Click on Create Role

3. Select AWS Accounts and select Another AWS Account from an AWS Account tab

4. specify Account ID as 911403356698(This is the Account Id of DigitalEx which is universal)

5. Check on options Require external ID and enter the tenant id. To get the tenant id to follow instructions,

   1. Login to DigitalEx

   2. From the side menu, select API under the Admin section

   3. Capture the Tenant ID & enter it into the External ID field

6. Click Next and don’t select any permissions

Enter the role name with prefix ‘DigitalEx-’ e.g: DigitalEx-rolename

7. Enter the Role name and click Create role.

   

8. A new role should be created and displayed in the list.

9. Click on the newly created Role which is navigated to the below page

10. Click on Add Permissions -> Create Inline Policy under Permissions Tab

11. Click on JSON tab & replace existing JSON with the below JSON

12. Replace <BUCKET_NAME> on lines 11 & 12 with the name of the bucket captured in Step-1: Enable CUR & Cost Explorer

    JSON
