Developed a Terraform sample configuration for the terraform-google-modules/terraform-docs-samples repository, focusing on enabling instance flexibility within regional managed instance groups (RMIG) on Google Cloud Platform. The work involved authoring HCL code to define an instance template and RMIG bindings, allowing rank- and machine-type-based instance selections for improved resource management. Provider requirements were updated to leverage the beta provider and enforce a minimum version supporting these features. The contribution included clear documentation and alignment with repository conventions, providing a practical, documentation-friendly example for users seeking to implement RMIG instance flexibility using Terraform and cloud infrastructure best practices.
