Frequently Asked Questions

Are these Dockerfiles production-ready?

The templates follow Docker best practices and are suitable as starting points for production. You may need to adjust them for your specific framework, dependencies, or deployment requirements.

What is a multi-stage build?

Multi-stage builds use multiple FROM instructions in a single Dockerfile to separate the build environment from the runtime environment, resulting in smaller, more secure production images.
