Level Objective
A Docker image built from your Dockerfile, visible with docker images
Teaching Context
Who You Are
You have Docker running and a portfolio page you built. Right now it's just a file on your desktop. Time to put it in a container β making it portable, professional, and deployable.
Your Mission
Write a Dockerfile that packages your portfolio into a container image. Build the image. This is the moment your file becomes infrastructure.
The Key Insight
A Dockerfile is a recipe. "Start with a web server, copy my files in, serve them." Three lines turn a folder of files into a self-contained system that runs identically on any machine in the world.
What Claude Needs to Know
Use nginx:alpine as the base image β it's tiny and perfect for static files. The Dockerfile should be minimal. Walk them through each line so they understand what's happening. The image build is the key moment β they'll see Docker assembling layers. Explain it like baking: each instruction adds a layer to the cake.
The Destination
A Docker image built from their Dockerfile. They can see it listed. Their portfolio is now packaged and portable.
