Create ROLE with Terraform in AWS with SAML provider attached

Question

I'm currently trying to automate AWS account provisioning, and one the steps is to create IAM ROLE, with Identity provider(for federated user access). I searched, and checked Terraform documentation, but cannot find any information about creating such role, or attaching provider to a role. I can create both just fine, but they are independent. here is portion of the code:

resource "aws_iam_saml_provider" "default" {
  name                   = "ADFS-TEST"
  saml_metadata_document = "${file("../../FederationMetadata.xml")}"
}

resource "aws_iam_role" "role" {
    name = "test-Admins"
}

Answer 1

figured out. here is full block

resource "aws_iam_saml_provider" "test" {
  name                   = "ADFS-TEST"
  saml_metadata_document = "${file("../../FederationMetadata.xml")}"
}

resource "aws_iam_role" "role" {
    name = "ADFStest-Admins"
    assume_role_policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "",
      "Effect": "Allow",
      "Principal": {
        "Federated": "${aws_iam_saml_provider.test.arn}"
      },
      "Action": "sts:AssumeRoleWithSAML",
      "Condition": {
        "StringEquals": {
          "SAML:aud": "https://signin.aws.amazon.com/saml"
        }
      }
    }
  ]
}
EOF

}

resource "aws_iam_role_policy" "admins" {
    name        = "Admin-Policy"
    #description = "A test policy"
    role = "${aws_iam_role.role.id}"
    policy = <<EOF
{
  "Version": "2012-10-17",
    "Statement": [
      {
        "Effect": "Allow",
        "Action": "*",
        "Resource": "*"
      }
  ]
}
EOF
}
