"Works on my machine" is a lie. Docker makes it true. We package our app into a container that runs anywhere, just like Netflix does.

Mission Briefing

⏱️ Before You Watch (5 mins)

Today's Secret: Why does Netflix work on your TV, your phone, and your laptop exactly the same way? The answer is Docker. It stops the dreaded error: "But it works on MY machine!"

What you should have ready:

Docker Desktop installed and running
Your saved Snake Game
Antigravity open

🧠 Quick Concepts

Term	Simple Meaning
Container	A "Magic Lunchbox" that keeps your app fresh anywhere
Image	The recipe for your lunchbox
Dockerfile	The instructions for the chef (how to build the image)
Port	A specific door on your computer (like 3000 or 8080)

🤔 Think About

Before watching, consider:

Have you ever sent a file to a friend and they couldn't open it because they "didn't have the right font"?
Docker solves this for code. It sends the font, the program, and the file all in one box.

🎯 By the End

After this episode, you'll:

✅ Understand why Docker changed the world
✅ Write your first Dockerfile
✅ Run your game inside a container!

Let's package your app! 📦

Phase 3: Debrief

Mission Report

📝 What We Learned

The Problem: Apps behave differently on different computers.
The Solution: Docker Containers. They package the Operating System, the Code, and the Tools into one "Standardized Shipping Container."
Dockerfile: A simple text file that tells Docker how to build your container.
Build vs Run: You "Build" an image (like baking a cake), then you "Run" a container (eating a slice).

🔗 Key Commands

# Build the image from your Dockerfile
docker build -t my-snake-game .

# Run the container (Map port 3000 on laptop to 3000 in container)
docker run -p 3000:3000 my-snake-game
