I am trying to set up multi-account AWS SAM deployments with GitLab CI/CD by following this article (multi-account AWS SAM deployments with GitLab CI/CD.
While setting up, in step 2, it asked for The aws:userid for the IAM principal used by the Gitlab runner.
I have gitlab runner on AWS EC2 instance and it doesn't have any IAM role attached to it. And, the runner is working perfectly fine.
Problem is, I can't get the idea of this aws:userid that I need to paste to follow the article. What exactly i need to input here as the value of "CIAccountSTSCondition"?
I tried to get the idea from AWS documentation but its not helping.
