Docker Compose for Development

Docker Compose simplifies multi-container development environments. Here's a practical guide.

Why Use Docker Compose?

  • Consistent environments across team members
  • Service orchestration with a single command
  • Isolated dependencies per project

Basic Setup

version: "3.8"
services:
  app:
    build: .
    ports:
      - "8000:8000"
    depends_on:
      - db
      - redis

  db:
    image: postgres:15-alpine
    environment:
      POSTGRES_DB: myapp

  redis:
    image: redis:7-alpine

Development Workflow

# Start all services
docker-compose up -d

# View logs
docker-compose logs -f app

# Rebuild after changes
docker-compose build app
docker-compose up -d app

Hot Reload

Mount your source code as a volume to enable hot reload during development. This lets you edit code and see changes immediately.
