Major refactoring to improve code organization and maintainability: Structure improvements: - Split monolithic script into 26 focused functions - Organized into logical sections with clear headers - Added comprehensive documentation and comments - Moved all configuration to the top as readonly arrays Code quality improvements: - Created reusable functions to eliminate duplication - Consistent error handling with logging functions - Better separation of concerns - Clear main() function showing high-level flow - Proper use of local variables and return codes Maintained functionality: - All existing features preserved - Bug fixes retained (array-based 1Password domain handling) - Docker DNS preservation intact - All domain resolutions and firewall rules unchanged This refactoring makes the script easier to understand, test, debug, and extend while maintaining 100% feature parity.
- Remove root .devcontainer directory (not needed for template repository) - Move image sources from docker-image/ to image-sources/ directory structure - Restructure to follow Dev Container template spec with self-contained templates in src/ - Update GitHub Actions workflow to build from image-sources/ - Update documentation to reflect new architecture - Remove interactive create-limited-git-setup.sh script for cleaner automation This restructuring separates concerns properly: templates are self-contained in src/ and use pre-built images, while image sources are maintained separately for CI/CD pipeline consumption.
- Replace separate build-image.yml and publish-templates.yml with unified build-and-publish.yml - Implement Dev Container spec-compliant semantic versioning for templates and images - Add PR build support with pr-<number> tags for testing changes before merge - Support multi-template builds with matrix strategy for scalability - Add comprehensive VERSIONING.md documentation for release process - Bump template version to 1.0.1 following semantic versioning standards The unified workflow streamlines CI/CD operations while maintaining proper versioning and enabling thorough testing of changes through PR builds.
- Fix GitHub Actions output format for multi-line JSON - Fix devcontainer CLI namespace argument (use --namespace instead of --registry-namespace)

Summary
This PR significantly improves our CI/CD pipeline by implementing a unified workflow system with proper semantic versioning support and enhanced testing capabilities.
Key Improvements
• Unified Workflow: Consolidated separate
build-image.ymlandpublish-templates.ymlinto a singlebuild-and-publish.ymlworkflow that handles both Docker images and OCI templates efficiently• Semantic Versioning Compliance: Implemented proper semantic versioning following the Dev Container specification, ensuring consistent version management across templates and images
• PR Testing Support: Added
pr-<number>tag generation for pull requests, enabling thorough testing of changes before they reach the main branch• Multi-Template Architecture: Built-in support for multiple templates using matrix builds, preparing the repository for future template additions
• Comprehensive Documentation: Added
VERSIONING.mdwith clear guidelines for version management and release processesTechnical Changes

Test Plan
This enhancement positions our CI/CD pipeline for better maintainability, testing, and compliance with Dev Container standards.
