Question

You are defining an AWS IAM policy inline in Terraform. Rather than hardcode a JSON string, you want to build the policy from HCL data structures so it stays readable and can reference other resource attributes. Which built-in function should you use to convert an HCL object into the JSON string the policy argument expects?

Accepted Answer

jsonencode() to serialize the HCL object into a JSON-formatted string

Answer

jsondecode() to parse the HCL object into a JSON string

Answer

templatefile() to render the object through an external template

Answer

yamlencode() to serialize the object, since IAM accepts YAML policies
