Terraform module to provision two IAM roles and two IAM groups for assuming the roles provided MFA is present, and add IAM users to the groups.

Role and group with Administrator (full) access to AWS resources
Role and group with Readonly access to AWS resources

To give a user administrator's access, add the user to the admin group.

To give a user readonly access, add the user to the readonly group.

[!TIP]

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform. Works with Github Actions, Atlantis, or Spacelift.
<details> <summary>Watch demo of using Atmos with Terraform</summary> <img src="https://github.com/cloudposse/atmos/blob/master/docs/demo.gif?raw=true"/> Example of running <a href="https://atmos.tools"><code>atmos</code></a> to manage infrastructure from our <a href="https://atmos.tools/quick-start/">Quick Start</a> tutorial. </detalis>

Usage

module "assumed_roles" {
  source              = "git::https://github.com/cloudposse/terraform-aws-iam-assumed-roles.git?ref=master"
  namespace           = "cp"
  stage               = "prod"
  admin_name          = "admin"
  readonly_name       = "readonly"
  admin_user_names    = ["User1","User2"] # Add these IAM users to the admin group
  readonly_user_names = ["User3","User4"] # Add these IAM users to the readonly group
}

[!IMPORTANT] In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.
