Terraform Enterprise Runs Reliant on aws Executable Fail with "Exit Status: 127. Output: /bin/sh:aws: not found."

Problem

After upgrading Terraform Enterprise to v202305-1 or later, runs utilizing local-exec provisioner with command = "aws" fail with Exit Status: 127. Output: /bin/sh:aws: not found.

Cause

• From  v202304-1 (692) release notes:
  • Terraform Build Workers are deprecated and will be removed in Terraform Enterprise v202305-1. The base image responsible for executing Terraform runs is now hashicorp/tfc-agent
• This new base image does not include the aws executable.

Solutions:

• To guarantee aws cli availability, requires building a custom agent image with aws installed. This article details the process.
