Final Project: Containerize a Web App

Time to package a real application with Docker.

Requirements

1. Write a Dockerfile for an existing app of yours (or a simple new one), ordering instructions so dependency installation is cached separately from your source code.
2. Build the image and run it as a container, confirm it works by accessing it from your browser or a REST client.
3. Add a second service the app depends on (a database, cache, etc.) using a docker-compose.yml file.
4. Use a named volume so that service's data survives docker compose down and docker compose up again.
5. Pass at least one piece of configuration in via an environment variable rather than hardcoding it.

Stretch goals

• Add a .dockerignore file to keep node_modules/.git/etc. out of your image.
• Use a multi-stage build to keep the final image small.
• Push your image to Docker Hub.
