Support OpenTofu

[chenrui333]

Just log an issue once OpenTF stable release is available :)

v1.6 has been out for a couple of months and seems to work with all the usual tooling.

At this moment if you need to have a support of Terraform as well as OpenTofu (and Terragrunt :) ) in one tool you can use https://github.com/tofuutils/tenv which my team wrote some months ago. A lot of users switched to that tool to unify version management in the world of Terraform.

You're welcome to open any issues or contribute to tenv.

Tried using Rover today, but ran into an issue where:

2025/09/05 10:12:19 Unable to parse Plan: Unable to initialize Terraform Plan: exit status 1

Error: Variables not allowed

  on main.tf line 11, in terraform:
  11:     bucket       = "${var.aws_profile}-terraform-state"

Variables may not be used here.


Error: Variables not allowed

  on main.tf line 16, in terraform:
  16:     profile      = var.aws_profile

Variables may not be used here.

with code

terraform {
  required_version = ">= 1.0"
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }

  backend "s3" {
    bucket       = "${var.aws_profile}-terraform-state"
    key          = "vpc/terraform.tfstate"
    region       = "us-east-1"
    encrypt      = true
    use_lockfile = true
    profile      = var.aws_profile
  }
}

This code is not valid in Terraform, but is valid in OpenTofu.
