This commit enhances the Docker diagnostics system with comprehensive Swarm-specific health checks to ensure the application is properly deployed in a Docker Swarm/CapRover environment. Changes: - Add check_swarm_status() function to verify Docker Swarm configuration - Checks if Docker is running in Swarm mode - Retrieves and logs Swarm node information (hostname, role, state) - Detects if container is running as a Swarm service task - Provides clear diagnostic messages for troubleshooting - Integrate Swarm checks into application startup (app.py) - Runs after Docker connection is verified - Logs success for production Swarm deployments - Warns (but doesn't fail) for local development environments - Add comprehensive test coverage (8 new tests) - Tests for active/inactive Swarm states - Tests for error handling and edge cases - Tests for node retrieval and hostname detection - Maintains 99% overall code coverage (128 tests passing) This ensures that Docker Swarm-related issues are caught early during deployment and provides clear diagnostic information for troubleshooting CapRover deployments with Docker socket mounting. https://claude.ai/code/session_01RRUv2BWJ76L24VyY6Fi2bh
