Lab: Getting Started with Docker
Table of contents
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
Start the labspace:
$ docker compose -f oci://dockersamples/labspace-container-getting-started up -dOpen your browser to http://localhost:3030.
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
Dockerfileto package an application, using layer caching for fast rebuilds - Build a custom image with
docker buildand run it as a container - Optionally publish your image to Docker Hub
