Docker Deployment Guide

Philosophy

Containers are immutable. Build once, run anywhere. Configuration lives outside the image.

Core Principles

1. One process per container - Containers should do one thing well
2. Immutable infrastructure - Never modify running containers
3. Configuration as environment - Secrets and config via env vars or mounts
4. Minimal images - Smaller = faster + more secure
