Implements support for both Terraform and OpenTofu binaries using
separate Dockerfiles with minimal code changes. This enables teams
to use either binary while maintaining security compliance, with
OpenTofu as the default and a clear deprecation path for Terraform.
Changes:
- Updated runner.Dockerfile and runner-azure.Dockerfile to OpenTofu v1.11.2
- Created runner-terraform.Dockerfile and runner-terraform-azure.Dockerfile
- Updated CI/CD workflows to build all 4 image variants
- Added binary detection in runner/server.go
- Added Terraform v1.14.3 support via separate images
- Updated documentation for binary selection
- Removed unnecessary BINARY_TYPE build arguments
Images published:
- OpenTofu (default): v{VERSION}, latest
- Terraform: v{VERSION}-terraform, latest-terraform
Binary versions:
- OpenTofu: 1.11.2
- Terraform: 1.14.3 (up from 1.5.7)
Breaking changes for Terraform users:
- S3 backend role_arn deprecated (use assume_role block)
- -state flag deprecated (use backend configuration)
- See IMPLEMENTATION_VERIFICATION.md for migration guidance
