Terraform AWS IAM module

About:

Basic AWS IAM role and policy module that expects 2 json files (see directory: ./lambda-policy-example/):

1. Assume role policy, defines the principle service actor. In the example that is Lambda.
2. Access policy, defines the policies that determine which services the assumed role has access to.

How to use:

You can copy the example files in the local module policies directory. To set up variables you can use the role_vars parameter to pass thm along to the json policy file.

module "iam" {
  source = "github.com/rpstreef/tf-iam?ref=v1.2"

  namespace         = var.namespace
  region            = var.region
  resource_tag_name = var.resource_tag_name

  iam_module_enabled = var.iam_module_enabled

  assume_role_policy = file("${path.module}/policies/lambda-assume-role.json")
  template           = file("${path.module}/policies/lambda.json")
  role_name          = "${local.lambda_function_name}-role"
  policy_name        = "${local.lambda_function_name}-policy"

  role_vars = {
    cognito_user_pool_arn = var.cognito_user_pool_arn
  }
}
