It Worked on My Machine… Docker Fixed It (Node.js + Multi-Stage Build)
I built a Node.js app… it worked perfectly on my machine.
But the moment I tried to run it somewhere else, it broke.
In this video, we fix that using Docker—and then take it further by making the image production-ready using multi-stage builds.
This is not just theory. We:
• Build a real app
• See why it fails
• Dockerize it step by step
• Optimize it for production
You’ll learn:
• What problem Docker actually solves
• How to write a clean Dockerfile
• What multi-stage builds are and why they matter
• How to create smaller, cleaner, production-ready images
This is the kind of workflow you’ll use in real DevOps and cloud environments.
