## Resource

In this lesson, you’ll learn about: applying Docker to real-world apps and scalable architecture principles1. Framework-Based Starter Projects The episode provides 7 ready-to-use starter projects for popular frameworks: Flask Express (Node.js) .NET Django Ruby on Rails Golang Laravel Each project includes: Dockerfile docker-compose.yml 👉 Goal: get you running fast with real applications in Docker2. Logging to Standard Output (stdout)❌ Problem: Writing logs to files inside containers Logs are lost when the container stops or restarts ✅ Best Practice: Log everything to stdout print("App started") Benefits: Managed by Docker daemon Easy to: View → docker logs Rotate logs Send to monitoring systems 3. Environment-Based Configuration Use environment variables instead of hardcoding values Example:DB_HOST=redis APP_ENV=production Benefits: Switch between environments easily: Development Testing Production No need to change source code 4. Stateless Application Design ("Stupid Apps")❌ Bad Practice: Storing data inside the app container Example: Sessions in memory ✅ Best Practice: Keep apps stateless Store data in external services like: Redis (sessions, cache) Databases Why this matters: Containers can: Restart anytime Scale horizontally 👉 No data should be lost5. The 12-Factor App Philosophy These practices are based on: 12 Factor App Core Ideas: Config via environment variables Logs treated as event streams Stateless processes Portable across environments 6. Real-World ImpactFollowing these principles allows you to: Scale applications easily Avoid downtime/data loss Deploy consistently across: Local Cloud CI/CD pipelines Key Takeaways Starter projects help you skip setup and start building Always log to stdout Use .env for configuration Keep apps stateless Follow 12-Factor Ap…
