+# Environment Configuration
+
+This project uses environment-specific configuration files to manage different deployment and testing scenarios.
+
+## Environment Files
+
+- `.env.development` - Configuration for local development
+- `.env.integrate_test` - Configuration for integration testing  
+- `.env.example` - Example configuration template
+
+## Usage
+
+### Development
+```bash
+# Uses .env.development by default or when ENVIRONMENT=development
+cargo run
+
+# Explicitly set development environment
+ENVIRONMENT=development cargo run
+```
+
+### Integration Testing
+```bash
+# Run integration tests (automatically uses .env.integrate_test)
+ENVIRONMENT=integrate_test cargo run
+
+# Run Python integration tests
+python -m pytest tests/integrate/ -v
+```
+
+## Key Differences
+
+### Development (.env.development)
+- Port: 3000
+- Database: `container_engine` 
+- Namespace: `container-engine-dev`
+- Domain: `dev.container-engine.app`
+- Log level: debug
+
+### Integration Test (.env.integrate_test)
+- Port: 3001 (avoids conflicts)
+- Database: `container_engine_test`
+- Namespace: `container-engine-test` 
+- Domain: `test.container-engine.app`
+- Log level: info
+
+## Port Separation
+
+Different ports are used to prevent conflicts when running development server and tests simultaneously:
+- Development: port 3000
+- Integration tests: port 3001
+
+This ensures GitHub Actions and local testing won't encounter "port already in use" errors.

+# GitHub Actions Port Conflict Fix
+
+## Problem
+GitHub Actions integration tests were failing due to port conflicts. The issue occurred because:
+
+1. GitHub Actions provides PostgreSQL (port 5432) and Redis (port 6379) as services
+2. The test setup code attempted to start its own Docker containers on the same ports
+3. This caused port binding conflicts and test failures
+
+## Solution
+Added environment detection to automatically handle both CI and local development environments:
+
+### Key Changes
+
+1. **Environment Detection** (`tests/integrate/conftest.py`)
+   - Added `_detect_github_actions()` method that checks for:
+     - `GITHUB_ACTIONS=true`
+     - `CI=true` 
+     - `RUNNER_OS` environment variable
+
+2. **Conditional Container Management**
+   - **In GitHub Actions**: Skip Docker container creation, use provided services
+   - **In Local Development**: Start Docker containers as before
+
+3. **Updated Cleanup Logic** (`tests/run_tests.sh`)
+   - Skip container cleanup in CI environments
+   - Preserve normal cleanup in local development
+
+### Testing
+The fix was comprehensively tested with 6 test cases covering:
+- Environment detection in various CI scenarios
+- Container management logic for both environments
+- Proper cleanup behavior
+
+## Usage
+
+### Local Development
+```bash
+# Works as before - containers are started automatically
+make test-integration
+```
+
+### GitHub Actions
+```yaml
+# No changes needed - detection is automatic
+- name: Run integration tests
+  run: python -m pytest tests/integrate/ -v
+```
+
+The fix automatically detects the environment and handles container management appropriately, eliminating port conflicts while maintaining compatibility with existing workflows.
