commit d417281ee08c468fbf1184b06cb7a2007d5a7e08 Author: Patrick de Ruiter Date: Mon Nov 17 00:32:51 2025 +0100 feat: Repurpose module from Ansible EDA to Renovate bot deployment Complete rewrite of the module to deploy a Renovate bot for automated dependency management with Gitea integration. Breaking Changes: - Module purpose changed from Ansible EDA to Renovate bot - All variables restructured for Renovate configuration - State file path updated to home/docker/renovate/renovate.tfstate - Volumes changed from EDA rulebooks/logs to config/cache - Container image now uses renovate/renovate:latest Added: - Gitea platform integration with token authentication - Renovate configuration template (config.js.tpl) - Repository configuration examples - Gitea Actions workflow examples - SonarQube integration examples - Comprehensive documentation (README, QUICKSTART, MIGRATION_GUIDE) - CHANGELOG.md for version tracking - Security best practices Removed: - All Ansible EDA-specific configuration - Traefik labels (not needed for Renovate) - Old EDA documentation files - example-rulebook.yml Updated: - Complete README with Gitea setup instructions - terraform.tfvars with Renovate configuration - All resource names from ansible_eda to renovate - Backend state path This is version 2.0.0 - not backward compatible with previous EDA version.
