Description

Install SAML.to as an IAM Provider to an AWS Account.

Usage

Option 1: Use the Generated Trust Policy

# Creates a SAML Provider in AWS for SAML.to
module "saml_to_iam" {
  source  = "saml-to/iam/aws"

  owner = "a_github_user_or_organization"
}

# Create a role which trusts SAML.to
resource "aws_iam_role" "my_role" {
  name               = "my_role"
  assume_role_policy = module.saml_to_iam.trust_policy
}

Option 2: Generate a Custom Trust Policy

# Creates a SAML Provider in AWS for SAML.to
module "saml_to_iam" {
  source  = "saml-to/iam/aws"

  owner = "a_github_user_or_organization"
}

# Create a Trust Policy
data "aws_iam_policy_document" "saml_to_trust" {
  statement {
    actions = module.saml_to_iam.trust_actions
    effect  = "Allow"

    principals {
      identifiers = module.saml_to_iam.trust_principal_identifiers
      type        = module.saml_to_iam.trust_principal_type
    }

    condition {
      test     = module.saml_to_iam.trust_condition_saml_test
      variable = module.saml_to_iam.trust_condition_saml_variable
      values   = module.saml_to_iam.trust_condition_saml_values
    }
  }
}

# Create a role which trusts SAML.to
resource "aws_iam_role" "my_role" {
  name               = "my_role"
  assume_role_policy = data.aws_iam_policy_document.saml_to_trust.json
}
