# Lab: Getting Started with Docker Start from zero and learn Docker's core building blocks. You'll run pre-built containers, write a `Dockerfile` to package a Node.js app, build your own image, and see container immutability and isolation in action. ## Launch the lab

  1. Start the labspace:

    $ docker compose -p labspace -f oci://dockersamples/labspace-container-getting-started up -d

  2. Open your browser to http://localhost:3030.

  3. When you're done, tear down the labspace:

    $ docker compose -p labspace down
## What you'll learn By the end of this Labspace, you will have completed the following: - Understand what containers are and how they differ from virtual machines - Run containers in the background, inspect their logs and filesystem, and manage their lifecycle - Write a `Dockerfile` to package an application, using layer caching for fast rebuilds - Build a custom image with `docker build` and run it as a container - Optionally publish your image to Docker Hub ## Modules | # | Module | Description | | --- | ------------------------- | ------------------------------------------------------------------------------ | | 1 | Welcome to Docker | Introduction to containers and running your first `hello-world` container | | 2 | Running Containers | Launch Nginx, inspect logs and internals, and manage the container lifecycle | | 3 | Building Your First Image | Write a `Dockerfile` and build a custom image from a Node.js app | | 4 | Running Your App | Run your image, explore container isolation, and optionally push to Docker Hub | | 5 | Wrap-up | Summary of key concepts and next steps |
