How I Reduced a Next.js Docker Image from 3.39 GB to 619 MB (82% Reduction)

Really enjoyed this one. Docker image optimization is one of those topics that most people ignore until build times and image size start hurting real deployments, so it was great to see a practical breakdown instead of just generic advice.

Cutting the image size by that much is impressive, but what I like even more is the mindset behind it — thinking about production efficiency, not just making the app run locally. That’s exactly the kind of detail that makes a big difference when you’re working with CI/CD pipelines and cloud deployments.

I’m also spending more time on DevOps and cloud-related content these days, so posts like this are especially useful because they connect optimization with real-world impact. Solid write-up overall.
