Some checks failed
continuous-integration/drone/push Build is failing
- Fix bash error in generate_env.sh with proper environment variable handling - Add docker-compose command detection for better compatibility - Add generate-env-prod command with production warnings - Make generate-env non-interactive by default for easier automation - Add generate-env-interactive for when user input is needed - Expand .env.example with more configuration options - Add helpful production deployment warnings Resolves: 'make generate-env generates nonsense' issue
