Docker Compose Hands-on Labs

Getting Started Tip

Choose the preferred way to run the labs. If you encounter any issues, please contact your instructor.

cd 001-intro
  • Open in Cloud Shell

Intro

  • This tutorial teaches Docker Compose through hands-on labs designed as practical exercises.
  • Each lab is packaged in its own folder and includes the files, manifests, and assets required to complete the lab.
  • Every lab folder includes a README that describes the lab’s objectives, tasks, and how to verify the solution.
  • The Docker Compose Labs are a series of exercises designed to teach players Docker Compose skills and features.
  • The inspiration for this project is to provide practical learning experiences for container orchestration and multi-service applications.

Pre-Requirements

  • You should be familiar with the following topics:
  • Basic Docker concepts (docker run, docker ps, docker build)
  • Basic Linux commands and shell scripting
  • Basic knowledge of YAML
  • Basic Git knowledge
  • Docker installed on your system
  • Docker Compose (included with Docker Desktop)

Usage

  • There are several ways to run the Docker Compose Labs.
  • Choose the method that works best for you.
  • Local environment with Docker Desktop (Recommended)
  • Using Google Cloud Shell

The easiest way to get started locally:

# Clone the repository
git clone https://github.com/nirgeier/DockerComposeLabs.git
cd DockerComposeLabs

# Start with Lab 1
cd Labs/001-intro

Prerequisites:

  • Docker installed and running
  • Docker Compose installed
  • Google Cloud Shell provides a free, browser-based environment with Docker tools pre-installed.
  • Click on the Open in Google Cloud Shell button below:

Open in Cloud Shell

  • The repository will automatically be cloned into a free Cloud instance.
  • Use CTRL + click to open it in a new window.
  • Follow the instructions in the README of each lab.

Preface

What is Docker Compose?

  • Docker Compose is a tool for defining and running multi-container Docker applications.
  • With Compose, you use a YAML file to configure your application’s services, networks, and volumes.
  • Then, with a single command, you create and start all the services from your configuration.

Key Benefits

  • Single command orchestration: docker compose up starts your entire stack
  • Declarative config: Your infrastructure is version-controlled in a YAML file
  • Environment consistency: Same setup across dev, CI, staging, and production
  • Service isolation: Independent networks and dependency management

What You’ll Learn

By completing all labs, you will be able to:

  1. Install and configure Docker Compose on any platform
  2. Define multi-service applications with networks, volumes, and dependencies
  3. Master every compose file directive (build, healthcheck, secrets, etc.)
  4. Manage the full lifecycle: build, run, debug, tear down
  5. Package Compose apps as Helm charts for Kubernetes deployment
  6. Use advanced patterns like extends and YAML anchors
  7. Implement live reload with Docker Compose Watch
  8. Design secure, segmented networks with DMZ and isolation
