IAM as Code

[PatrickXYS]

Basically, I think we need to enhance IAM as Code(IAC) to enable third-party users (kubeflow maintainers) to have ReadOnly Access to S3/ECR.

It can also save efforts in Optional-Test-Infra admin to check account resources back-and-forth.

So the way I want to move forward:

1. Define one YAML file, which consists of maintainers who want to have ReadOnly access to Optional-Test-Infra's S3/ECR.
2. Create IAM Group (Console-ReadOnly)
3. Create Cloud Formation Template which creates an IAM user with pre-defined IAM Group (Console-ReadOnly), and takes as an input parameter defined by user: UserName.
4. Create AWS Lambda function, trigger by CodeCommit push, and create a new IAM user through Cloud-Formation Template.
5. User who added in the YAML file, after a few minutes, can log into the Optional-Test-Infra account console and check S3/ECR afterward.

This is not an urgent task, but definitely, a bonus point that can make external users happy.

After a few investigations, seems like AWS organizations and SSO service would be a good fit

Maybe we don't have to make access-granting process fully-automated, allow only Admins to run some pre-defined command should be fine.
