Docker for Local Development Workflows

Why Docker for Development?

Docker solves the "works on my machine" problem by containerizing your entire development environment.

Getting Started

Basic Docker Compose setup:

version: '3.8'
services:
  db:
    image: postgres:15
    environment:
      POSTGRES_PASSWORD: dev
  app:
    build: .
    ports:
      - "3000:3000"
    volumes:
      - .:/app

Benefits

• Consistent environments
• Easy onboarding
• Isolated dependencies
• Production parity

Tips

• Use volume mounts for hot reload
• Keep images small
• Use multi-stage builds

Docker transforms how teams work together.
