This PR introduces a new GitHub Actions workflow to automate the infrastructure deployment process using Terraform. The workflow is designed to perform a terraform plan followed by a conditional terraform apply. The apply step is executed only if the workflow is manually triggered from the main branch, ensuring controlled updates.
Key Features:
Terraform Plan: Automatically generates a plan to show potential changes to the infrastructure, aiding in review and validation.
Conditional Apply: The terraform apply is conditionally run based on the trigger context. It is only executed when the workflow is manually triggered from the main branch, providing an extra layer of safety for production changes.
Role Assumption: Utilises a custom AWS IAM role, crafted to deploy resources to our Amazon EKS cluster. This role ensures that the workflow has the necessary permissions to execute actions within our AWS account securely.
