Terraform Version Update

Current State

• Current Minimum Version: 1.5 (folder module), 1.11 (other modules)
• Target Version: 1.12.x
• Affected Modules: All modules (account, data-set, data-source, folder, group, namespace, user, vpc-connection)

Version Analysis

Most modules are already at Terraform >= 1.11, but the folder module is still at >= 1.5. This update will standardize all modules to >= 1.12 for consistency and access to new features.

New Features in 1.12.x

• Enhanced Testing Capabilities: -parallelism=n option for terraform test command
• Improved Import Blocks: Support for importing via identity attribute
• Better Error Handling: Short-circuiting logical binary operators
• Performance Improvements: Better handling of high cardinality resources
• Enhanced UI: Elapsed time display in mm:ss format

Required Changes

• Update modules/folder/versions.tf from >= 1.5 to >= 1.12
• Verify all modules work with Terraform 1.12.x
• Run full test suite with new version
• Update any CI/CD pipelines to use Terraform 1.12.x
• Update documentation if needed

Migration Guide

1. Update version constraints:

   terraform {
     required_version = ">= 1.12"
     # ... rest of configuration
   }

2. Test the changes:

   terraform init -upgrade
   terraform plan
   terraform validate

3. Run tests:

   terraform test
   pre-commit run --all-files

Breaking Changes ⚠️

• Linux Kernel Requirement: Linux kernel version 3.2 or later now required (unlikely to affect most users)
• Test Files: External variables in test files now require variable definition blocks (if using terraform test)

Benefits

• Access to improved testing capabilities
• Better performance for high cardinality resources
• Enhanced import functionality
• Consistent version requirements across all modules
• Future-proofing for upcoming Terraform features
