How would you unify Docker setups for development and production?
Development and production environments often require unified Docker setups to ensure consistent behavior. How would you create a single Docker setup for both? Share any Dockerfile or Compose examples you use for this purpose.

Single Dockerfile with separate stages: Development stage with debugging tools and production stage optimized for performance.

Docker Compose Profiles: Define environment-specific services in docker-compose.yml and use profiles to switch dev or prod setups.

Externalize configurations: Use either environment variables or config files (.env file) to manage environment-specific settings, like credentials and ports.

Shared Volume Management: Use volumes for live-reloading during development and static code in production for stability.

Consistent Base Images: Use the same base image across environments to ensure compatibility.

Automated Testing: Validate both setups through tests in your CI/CD pipelines.

Documentation: Clearly document workflows for seamless team collaboration.

These practices ensure consistency, reduce errors, and streamline deployments.
