Just the Docker you need to know in 22 bite-sized lessons!

In Learn Docker in a Month of Lunches, Docker expert Elton Stoneman guides through everything you need to know about Docker in 22 short lessons you can complete on your lunch break. This freshly-revised bestseller has been updated for modern tools and the latest versions of Linux, Windows, or Mac, with new coverage of multi-platform builds, cloud container services, replatforming legacy Windows apps, and Kubernetes.

In Learn Docker in a Month of Lunches, Second Edition you’ll learn how to:

• Run applications in Docker containers on Linux and Windows
• Package applications as Docker images and share them on registries
• Model and run distributed applications with Docker Compose and Kubernetes
• Add instrumentation to containerized applications
• Build and deploy apps with Docker in a CI/CD process

Docker revolutionized the way engineers build software. By bundling an application together with all its dependencies in a portable “container” that can be deployed almost anywhere, Docker makes it possible to manage applications without creating custom infrastructures. Free, open source, and battle-tested, Docker has quickly become must-know technology for developers and administrators.

About the Technology

Docker is a set of powerful tools to bundle software components in safe, portable “containers” you can drop wherever they’re needed. Whether you’re deploying a pre-built application, creating a secure test environment, or packaging microservices, you’re probably going to use Docker. This book gets you up to speed with the Docker skills you need—without the history, theory, and other “blah blah” you don’t.
