PR Description: GitHub Codespaces Development Environment

This PR introduces a complete GitHub Codespaces configuration for dotCMS, enabling developers to spin up a fully functional development environment in the cloud within minutes.

Tasks:

  • Read and analyze all devcontainer configuration files
  • Understand the setup and post-start scripts
  • Create comprehensive PR description

🎯 What This PR Adds

New Files Added:

  • .devcontainer/devcontainer.json (144 lines) - Main Codespaces configuration
  • .devcontainer/setup.sh (93 lines) - Environment setup and service initialization script
  • .devcontainer/post-start.sh (115 lines) - Status monitoring and user guidance script
  • .devcontainer/README.md (216 lines) - Comprehensive documentation and troubleshooting guide
  • .devcontainer/.gitattributes (2 lines) - Ensures shell scripts use Unix line endings

  • PostgreSQL 18 with pgvector extension - Database layer
  • OpenSearch 1.x - Search and indexing engine

Development Tools

  • Java 21 (Eclipse Temurin) with Maven - Backend development
  • Node.js 20 with npm/nvm - Frontend development
  • GitHub CLI - Repository management
  • Docker-in-Docker - Container orchestration

VS Code Extensions

Pre-configured with essential extensions:

  • Java Development Pack - Complete Java tooling
  • Angular & TypeScript support for frontend development
  • Docker & Git integration
  • REST Client, YAML support, and more productivity tools

🚀 Key Features

Automated Service Management

  • Intelligent setup script that detects workspace location and initializes services
  • Health checking with Docker daemon readiness detection
  • Service monitoring with container status reporting

Port Forwarding Configuration

Pre-configured forwarding for all essential services:

  • 8082 - dotCMS HTTP
  • 8443 - dotCMS HTTPS
  • 9200 - OpenSearch REST API
  • 5432 - PostgreSQL database
  • 5005 - Java Debug Port (JDWP)

Remote Debugging Support

  • JDWP debugging configuration for live dotCMS container debugging
  • VS Code integration with breakpoint support
  • Debug profiles pre-configured for immediate use

Developer Experience

  • Oh My Zsh shell with enhanced terminal experience
  • Auto-formatting and code organization on save
  • Comprehensive documentation with troubleshooting guides
  • Quick command reference for common Docker operations

🔧 Technical Implementation

Environment Setup Process

  1. Docker-in-Docker initialization with privileged container mode
  2. Service orchestration using existing docker-compose-examples/single-node-demo-site
  3. Health monitoring with intelligent waiting for service availability
  4. User notification system with colored terminal output

Smart Configuration

  • Git-based workspace detection for reliable path resolution
  • Docker Compose v2/v1 compatibility with automatic detection
  • Cross-platform line ending handling via .gitattributes
  • Container resource optimization with appropriate memory settings

📖 Documentation Highlights

The included README provides:

  • Step-by-step getting started guide
  • Service access information with default credentials
  • Advanced debugging setup instructions
  • Environment customization options
  • Comprehensive troubleshooting section
  • Docker image management guidance

🎯 Developer Benefits

Immediate Productivity

  • 5-10 minute setup from repository to running dotCMS instance
  • No local Docker/Java setup required
  • Consistent development environment across all developers

Professional Development Workflow

  • Full IDE experience with debugging, IntelliSense, and Git integration
  • Container management tools built-in
  • Database access and monitoring capabilities
  • REST API testing tools included

Flexible Usage

  • Branch-specific environments - create Codespaces from any branch
  • Persistent storage - work survives across Codespace restarts
  • Customizable configuration - easily modify services and tools

- Added `.devcontainer` configuration for setting up a fully functional dotCMS development environment in GitHub Codespaces.
- Included setup for Docker, PostgreSQL, OpenSearch, and required dependencies.
- Integrated VS Code extensions, port forwarding, and developer tooling.
- Added scripts (`setup.sh` and `post-start.sh`) to initialize and provide status updates for development services.
- Simplified setup instructions in `.devcontainer/README.md` by removing redundant options.
- Unified build command structure for easier usage.
- Increased `post-start.sh` readiness timeout to improve container stability.
- Fixed `dockerComposeVersion` typo in `devcontainer.json`.
- Removed unused Java configurations and environment variables.
…cker-in-docker` feature

- Added a wait loop in `setup.sh` to ensure Docker daemon is ready before proceeding.
- Replaced `docker-outside-of-docker` with `docker-in-docker` in `devcontainer.json` for better compatibility.
- Improved Docker readiness logic in `setup.sh`, including workspace detection and Docker Compose command resolution.
- Enhanced feedback for missing or misconfigured dependencies.
- Adjusted `docker-in-docker` feature version in `devcontainer.json` for compatibility.
…tion and Docker management

- Simplified workspace root resolution using Git.
- Improved Docker readiness wait loop and extended timeout.
- Updated Docker Compose configuration to use subfolder structure.
- Enhanced error handling and messaging for missing dependencies.
… workspace initialization

- Improved workspace root detection using Git and added error handling for non-Git environments.
- Updated Docker Compose command resolution to prioritize v2.
- Enhanced readiness checks for Docker daemon and dotCMS service with detailed feedback.
- Simplified and clarified quick command outputs for Docker management.
