Quickstart Terraform for AWS
- First, install terraform and set the PATH variable
- Create a folder which will contain your .tf files. cd to that folder (from a cmd prompt)
- From the same command prompt, type Terraform init – downloads all the libraries for the providers (including AWS)
- Specify a provider in your .tf file – as shown below (Use VS Code – recommended)
- Type terraform validate in the folder containing the tf file
- Type terraform apply in the folder containing the tf file
- The ‘assume role’ section specifies WHO is allowed to sts:AssumeRole. The role definition will fail without having at least one sts:AssumeRole principal.
Sample – create a security auditor role – and attach the managed policy – SecurityAudit to it. Also add, AWSSecurityHubFullAccess to the same role
provider "aws" {
version = "~> 2.0"
region = "us-east-1"
}
resource "aws_iam_role" "role" {
name = "security_auditor_role"
assume_role_policy = <<EOF
{
"Version": "2012-10-17",
"Statement": [
{
"Action": "sts:AssumeRole",
"Principal":{"AWS":"arn:aws:iam::MY_ACCT_NUMBER:root"},
"Effect": "Allow",
"Sid": ""
}
]
}
EOF
tags = {
resourcetype = "production_role"
}
}
resource "aws_iam_policy_attachment" "policies-attach1" {
name = "security-policies-attachment"
roles = ["security_auditor_role"]
policy_arn = "arn:aws:iam::aws:policy/SecurityAudit"
}
resource "aws_iam_policy_attachment" "policies-attach2" {
name = "security-policies-attachment2"
roles = ["security_auditor_role"]
policy_arn = "arn:aws:iam::aws:policy/AWSSecurityHubFullAccess"
}
