Getting Docker working with Next.js is easy. Getting it right — with proper layer caching, no hardcoded values, and a secure production image — takes a bit more thought. This guide walks you through every decision in a production-grade Dockerfile, explaining the why behind each choice so you can adapt it confidently to your own project.

By the end, you'll have a Dockerfile that:

• Maximises Docker layer caching so rebuilds are fast
• Never invalidates your node_modules cache when only application code changes
• Passes all configurable values as build arguments (no hardcoded ports or URLs)
• Uses multi-stage builds to keep the final image lean
• Runs as a non-root user in production
