feat: add Renovate for dependency management

[lgallard]

Summary

• Add renovate.json configuration for automated dependency management
• Configure Renovate to ignore Terraform core updates
• Disable major version updates for terraform providers to ensure stability
• Enable automated dependency updates for DNS/networking infrastructure components

Configuration Details

• Extends base Renovate configuration for standard behavior
• Ignores hashicorp/terraform to prevent core Terraform updates
• Disables major version updates for terraform providers to maintain compatibility
• Follows baseline patterns established in terraform-aws-secrets-manager module

Test Plan

• Verify renovate.json syntax is valid JSON
• Confirm configuration follows Terraform best practices for DNS/networking modules
• Ensure compatibility with existing release-please workflow
• Monitor first Renovate run for proper dependency detection

🕵️ Bug Hunt Analysis

Tasks:

• Read and analyze renovate.json configuration
• Check for security vulnerabilities and misconfigurations
• Verify Terraform-specific Renovate best practices
• Identify potential high-impact issues

🚨 Critical Issues Found

HIGH PRIORITY: Missing AWS Provider Constraint

• Issue: versions.tf:1-3 only constrains Terraform core (>= 1.0) but doesn't specify AWS provider version constraints
• Risk: Renovate can't manage AWS provider updates because no provider is declared - this defeats the purpose of dependency management
• Impact: Module could break with incompatible AWS provider versions used by consumers

MEDIUM PRIORITY: Overly Broad Base Configuration

• Issue: renovate.json:2 extends "config:base" which enables aggressive update patterns
• Risk: May create excessive PRs and noise, especially problematic for infrastructure modules
• Recommendation: Consider "config:recommended" for more conservative updates

MEDIUM PRIORITY: Incomplete Datasource Coverage

• Issue: renovate.json:8 only covers "terraform-provider" datasource for major version blocking
• Risk: Missing "terraform-module" datasource - major module updates could still cause breaking changes
• Impact: Breaking changes from module dependencies won't be prevented

✅ Positive Security Practices

• Correctly ignores Terraform core updates (hashicorp/terraform)
• Appropriately disables major provider updates for stability
• Valid JSON syntax with no injection risks

🔧 Recommended Fixes

1. Add AWS provider constraint in versions.tf:

   terraform {
     required_version = ">= 1.0"
     required_providers {
       aws = {
         source  = "hashicorp/aws"
         version = ">= 4.0"
       }
     }
   }

2. Expand major version blocking in renovate.json:

   "datasources": ["terraform-provider", "terraform-module"]

🔧 Addressing Bug Hunt Issues

Tasks:

• Read repository configuration and current files
• Fix HIGH PRIORITY: Add AWS provider constraint to versions.tf
• Fix MEDIUM PRIORITY: Expand datasource coverage in renovate.json
• Commit and push changes to PR branch

✅ Changes Implemented

versions.tf: Added AWS provider constraint to enable proper dependency management:

terraform {
  required_version = ">= 1.0"
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 4.0"
    }
  }
}

renovate.json: Expanded datasource coverage to prevent breaking module updates:

"datasources": ["terraform-provider", "terraform-module"]

🎯 Issues Resolved

• HIGH PRIORITY: AWS provider constraint now allows Renovate to manage AWS provider versions safely
• MEDIUM PRIORITY: Major version blocking now covers both terraform providers AND modules
• Renovate can now properly track and manage all Terraform dependencies in this DNS/networking module

All changes have been committed and pushed to the feat/task-004-add-renovate branch.

🕵️ Bug Hunt Analysis

Tasks:

• Read and analyze current renovate.json configuration
• Read and analyze current versions.tf file
• Check for security vulnerabilities and misconfigurations
• Identify any remaining critical bugs or performance issues
• Provide actionable bug hunt summary

🔍 Analysis Complete

Current State: The previous bug hunt fixes have been successfully implemented:

• ✅ AWS provider constraint now properly configured in versions.tf:4-7
• ✅ Renovate datasource coverage expanded to include both providers and modules in renovate.json:8

⚠️ REMAINING ISSUES IDENTIFIED

MEDIUM PRIORITY: Insecure Git Dependencies in Examples

• Location: examples/complete.tf:3 and examples/simple.tf:3
• Issue: External module references use unpinned git URLs:

  source = "git::https://github.com/rhythmictech/terraform-aws-route53-endpoint"

• Risk: Examples could break or introduce vulnerabilities when external repos change
• Recommendation: Pin to specific versions/tags or use Terraform Registry versions

LOW PRIORITY: Missing Renovate Schedule Configuration

• Issue: No schedule defined in renovate.json - defaults to frequent runs
• Impact: Could create noise with too many automated PRs
• Recommendation: Add timezone-aware scheduling:

  "schedule": ["before 6am on monday"]

✅ Security Analysis: PASSED

• No injection vulnerabilities in Renovate configuration
• Proper major version blocking prevents breaking changes
• AWS provider constraints prevent compatibility issues
• Core Terraform updates appropriately ignored

🎯 Verdict: Configuration is SECURE and FUNCTIONAL

The critical issues from the previous bug hunt have been resolved. Only minor improvements remain for example stability and update frequency control.

🕵️ Bug Hunt Analysis

Tasks:

• Read and analyze current renovate.json configuration
• Read and analyze current versions.tf file
• Check examples directory for any remaining issues
• Scan for any remaining security vulnerabilities or performance issues
• Provide comprehensive bug hunt summary

🔍 Analysis Complete

Current State: All critical and medium priority issues from previous bug hunts have been successfully resolved:

• ✅ AWS provider constraint properly configured in versions.tf:4-7
• ✅ Renovate datasource coverage expanded to include both providers and modules in renovate.json:8
• ✅ Git dependencies pinned to specific versions across all examples and documentation

⚠️ REMAINING MINOR ISSUES

LOW PRIORITY: Variable Type Specification

• Location: variables.tf:10
• Issue: Uses generic type = list instead of more specific typing
• Risk: Minimal - Terraform will still validate, but less explicit about expected structure
• Recommendation: Consider type = list(any) or more specific object type

LOW PRIORITY: Missing Renovate Schedule Configuration

• Issue: No schedule defined in renovate.json - defaults to frequent automated runs
• Impact: Could create noise with too many automated PRs
• Recommendation: Add schedule configuration like:

  "schedule": ["before 6am on monday"]

✅ Security Analysis: PASSED

• No injection vulnerabilities in any configuration files
• Proper version pinning prevents supply chain attacks
• AWS provider constraints prevent compatibility issues
• Core Terraform updates appropriately ignored
• RAM sharing configured with allow_external_principals = false (good security practice)
• Safe IP:PORT parsing logic in main.tf

🎯 Verdict: Configuration is SECURE and PRODUCTION-READY

All critical security vulnerabilities and bugs have been resolved. Only minor improvements remain for type safety and update frequency control.
