From 5e31ec1b20aa43ce506234727da95db256ec098d Mon Sep 17 00:00:00 2001 From: Your Name Date: Tue, 16 Sep 2025 13:44:42 -0400 Subject: [PATCH] Phase 1 Implementation: Simplify module interface and consolidate naming - Created defaults.tf with centralized module defaults - Updated variables.tf to remove redundant variables (repository_template, etc.) - Fixed main.tf to pass local values to templates instead of hardcoded defaults - Updated locals.tf to use new simplified variable structure - Fixed validation errors and template variable references - Updated examples to demonstrate simplified user interface - Consolidated repository and cluster naming to single 'name' variable - Hidden implementation complexity from users per call notes discussion Implements Phase 1 of callnotes-09152025 implementation plan.

**COMPLETED** + +1. **Created defaults.tf file** - All module defaults are now centralized: + - Dynamic AWS profile generation from account_name + environment_abbr + - Static repository template values (hidden from users) + - EKS bootstrap node group defaults for Karpenter + - Organization default settings (FinOps configurations) + +2. **Updated variables.tf** - Simplified user interface: + - Removed redundant variables: `repository_template`, `repository_template_owner` + - Cleaned up `cluster_config` object to only include user-configurable values + - Moved internal variables to separate sections for backward compatibility + - Consolidated naming to single `name` variable for both repository and cluster + +3. **Fixed main.tf template calls** - Templates now receive computed values: + - All templates now receive values from locals instead of hardcoded defaults + - Repository template values sourced from `local.repository_defaults` + - EKS sizing values sourced from `local.eks_defaults` + - Organization settings sourced from `local.organization_defaults` + +4. **Updated locals.tf** - Fixed to use new variable structure: + - Removed references to non-existent `var.cluster_config.cluster_name` + - Updated `config_json` to use `var.name` for cluster name + - Fixed all template variable references + +5. **Updated examples** - Simplified user interface demonstrated: + - Basic example now uses consolidated variable structure + - Removed all redundant configuration options + - Clear demonstration of minimal required inputs + +### 🔄 Next Steps + +#### Phase 2: Workspace Structure Implementation - **READY TO START** + +1. **Create eks-clusters-workspace Repository** + -
