aws_iam_policy, single resource, multiple data documents

[Duane Haas]

I have the following main.tf:

#Role that gets created in in identity account that okta uses to map AD groups to Roles in AWS

resource "aws_iam_role" "create_identity_role" {

count = "${length(var.team_name)}"

name = "${lookup(var.identity_role_name,element(var.team_name, count.index))}"

assume_role_policy = "${data.aws_iam_policy_document.trustokta.json}"

}

#Role that gets created in each of the accounts that will determine what it is a user will be able to do inside AWS

resource "aws_iam_role" "create_assume_role" {

count = "${length(var.team_name)}"

name = "${lookup(var.assume_role_name,element(var.team_name, count.index))}"

assume_role_policy = "${data.aws_iam_policy_document.trustawsaccount.json}"

}

#Policy that gets created in the identity account which tells AWS which role to assume in a different account

resource "aws_iam_policy" "create_assume_policy" {

count = "${length(var.team_name)}"

name = "${lookup(var.assume_role_name,element(var.team_name, count.index))}"

policy = "${data.template_file.network_assume.rendered}"

}

#Tie my role and policies together

resource "aws_iam_role_policy_attachment" "attach_assume_policy" {

count = "${length(var.team_name)}"

role = "${lookup(var.assume_role_name,element(var.team_name, count.index))}"

policy_arn = "${element(aws_iam_policy.create_assume_policy.*.arn, count.index)}"

}

My policy document looks like:

data "template_file" "platform_assume" {

 template = "${file("../policy_documents/identity/platform_assume.tpl")}"

}

data "template_file" "network_assume" {

 template = "${file("../policy_documents/identity/network_assume.tpl")}"

}

data "template_file" "workstation_assume" {

 template = "${file("../policy_documents/identity/workstation_assume.tpl")}"

}

data "template_file" "tradeops_assume" {

 template = "${file("../policy_documents/identity/tradeops_assume.tpl")}"

}

data "template_file" "investments_assume" {

 template = "${file("../policy_documents/identity/investments_assume.tpl")}"

}

data "template_file" "marketingdist_assume" {

 template = "${file("../policy_documents/identity/marketingdist_assume.tpl")}"

}

my issue is with main.tf, i'm unsure how to iterate through each of the different template files.  right now it iterates through and creates several policies all based on "${data.template_file.network_assume.rendered}" i want it to not only run an iteration based on that, but all other template file names inside the data document.  also need like a list or map of the different data.templates to cycle through, just now sure how to make it work.
