Docker Containerization Best Practices

Comprehensive containerization framework with 60+ rules across Dockerfile optimization, multi-service orchestration, production deployment, and development workflows. Designed for reliable, scalable container deployments from development to production.

When to Apply

Reference these guidelines when:

  • Containerizing Django, FastAPI, or Celery applications
  • Setting up multi-service architectures with Docker Compose
  • Implementing production deployment pipelines
  • Managing development environments consistently
  • Scaling containerized applications
  • Optimizing container performance and security
