✅ Complete Vertical Slice: Convert Firewall Template to Variables Pattern

This PR successfully implements a complete vertical slice to convert the configure-firewall.yml.tera template to use the centralized variables pattern, following issue #106 specification.

🎯 All Phases Complete

  • Phase 1: Convert template file to static with vars_files
  • Phase 2: Register static template in copy_static_templates()
  • Phase 3: Update AnsibleClient signature to accept extra_args
  • Phase 4: Update all AnsibleClient call sites
  • Phase 5: Update ConfigureFirewallStep to use variables file
  • Phase 6: Remove old firewall template rendering
  • Phase 7: Delete old .tera template file
  • Phase 8: Clean up firewall renderer/wrapper code (~675 lines removed)
  • Phase 9: Update documentation
  • Phase 10: Final validation (tests, linters, build verification)
  • Fix doctest failure

📋 Changes Summary

Template Conversion

  • ✅ Created static configure-firewall.yml (no .tera extension)
  • ✅ Added vars_files: [variables.yml] directive to playbook
  • ✅ Fixed variable syntax: {{ssh_port}} → {{ ssh_port }} (proper spacing)
  • ✅ Deleted old configure-firewall.yml.tera

API Updates

  • ✅ Updated AnsibleClient::run_playbook() signature to accept extra_args: &[&str]
  • ✅ Updated all 5 call sites for backward compatibility
  • ✅ Added comprehensive rustdoc with examples
  • ✅ Fixed doctest to use no_run attribute (prevents ansible-playbook requirement in CI)

Static Registration

  • ✅ Added configure-firewall.yml to static playbooks list in copy_static_templates()
  • ✅ Updated file count in debug log: 6 → 7

Rendering Cleanup

  • ✅ Removed firewall_playbook_renderer field from AnsibleTemplateRenderer
  • ✅ Removed renderer initialization in constructor
  • ✅ Removed firewall rendering call from render() method
  • ✅ Removed create_firewall_context() helper method
  • ✅ Removed FirewallPlaybookRenderingFailed error variant
  • ✅ Removed FirewallPlaybookTemplateRenderer from public exports

Code Cleanup (~675 lines removed)

  • ✅ Deleted src/infrastructure/external_tools/ansible/template/renderer/firewall_playbook.rs (347 lines)
  • ✅ Deleted src/infrastructure/external_tools/ansible/template/wrappers/firewall_playbook/ directory (328 lines)
  • ✅ Removed module exports from wrappers/mod.rs
  • ✅ Removed module exports from renderer/mod.rs
  • ✅ Verified zero remaining references in codebase

Documentation Updates

  • ✅ Updated docs/technical/template-system-architecture.md
  • ✅ Updated docs/contributing/templates.md
  • ✅ Updated templates/ansible/README.md

✅ Validation Complete

Tests:

  • ✅ All unit tests pass: cargo test (1065 tests, 0 failures)
  • ✅ All doc tests pass: cargo test --doc (233 tests, 0 failures)
  • ✅ Build succeeds: cargo build --release

Linters:

  • ✅ All linters pass: cargo run --bin linter all
  • ✅ No unused dependencies: cargo machete

Template Verification:

  • ✅ Static configure-firewall.yml copied to build directory
  • ✅ Playbook contains vars_files: [variables.yml]
  • ✅ variables.yml generated with correct SSH port

📊 Impact

  • Net change: +184 insertions, -765 deletions
  • Complexity reduced: No per-playbook renderer/wrapper/context needed
  • Pattern established: Future playbooks can follow this simpler approach
  • Maintainability improved: Centralized variable management

<issue_title>Convert Firewall Template to Variables Pattern (Complete Vertical Slice)</issue_title>
<issue_description>Parent Epic: #19 - Refactor Ansible Templates to Variables Pattern
Depends On: #105 - Create Variables Template Infrastructure

Overview

Convert the configure-firewall.yml.tera template to a static configure-firewall.yml playbook that loads variables from the centralized variables.yml file. This is a complete vertical slice that includes implementation, cleanup of old code, documentation updates, and full validation.

Goals

  • Template Conversion: Convert .tera template to static .yml playbook
  • Variables Integration: Add vars_files: [variables.yml] to load centralized variables
  • Static Registration: Register playbook in copy_static_templates() method
  • AnsibleClient Enhancement: Make generic to accept optional extra arguments
  • Call Site Updates: Update all AnsibleClient call sites for new signature
  • Cleanup: Remove old firewall renderer/wrapper code (~500 lines)
  • Documentation: Update architecture docs, contributing guide, templates README
  • Validation: Full test suite, build verification, E2E preparation

🏗️ Architecture Requirements

DDD Layer: Infrastructure (template system) + Adapters (AnsibleClient)

Pattern: Static template copying + Ansible vars_files

Time Estimate

4.5 days - Complete vertical slice (11 phases):

  • Phases 1-8: Template conversion and API updates (2.75 days)
  • Phase 9: Clean up old architecture (2-3 hours)
  • Phase 10: Update documentation (1-2 hours)
  • Phase 11: Final integration validation (0.5-1 hour)

Documentation

Full implementation details: docs/issues/19.2-convert-firewall-template-to-static.md

Acceptance Criteria

Template Conversion

  • configure-firewall.yml is static (no .tera extension)
  • Playbook contains vars_files: [variables.yml]
  • Old .tera template deleted

API Updates

  • AnsibleClient::run_playbook() accepts extra_args parameter
  • All call sites updated to new signature
  • Firewall step passes &["-e", "@variables.yml"]

Cleanup (~500 lines removed)

  • firewall_playbook.rs renderer deleted (~350 lines)
  • wrappers/firewall_playbook/ directory deleted (~150 lines)
  • Module exports removed
  • No remaining references in codebase

Documentation

  • Template system architecture updated
  • Contributing templates guide updated
  • Templates README updated
  • Examples for future developers

Testing & Validation

  • Unit tests pass: cargo test
  • Config tests pass: cargo run --bin e2e-config-tests
  • Linters pass: cargo run --bin linter all
  • Build directory structure verified
  • Template contents verified

@copilot, the "testing" workflow is failing:

@copilot, the "testing" workflow is failing:

Fixed in commit 73845dc. The doctest example in AnsibleClient::run_playbook() was calling .unwrap() which failed when ansible-playbook is not installed in the CI environment. Added no_run attribute to the doctest to prevent it from executing while still validating the code compiles.

All doc tests now pass:

cargo test --doc --workspace
test result: ok. 233 passed; 0 failed; 5 ignored
