Docker Certified Associate (DCA): Exam Guide

By: Francisco Javier Ramírez Urea

Overview of this book

Developers have changed their deployment artifacts from application binaries to container images, and they now need to build container-based applications as containers are part of their new development workflow. This Docker book is designed to help you learn about the management and administrative tasks of the Containers as a Service (CaaS) platform. The book starts by getting you up and running with the key concepts of containers and microservices. You'll then cover different orchestration strategies and environments, along with exploring the Docker Enterprise platform. As you advance, the book will show you how to deploy secure, production-ready, container-based applications in Docker Enterprise environments. Later, you'll delve into each Docker Enterprise component and learn all about CaaS management. Throughout the book, you'll encounter important exam-specific topics, along with sample questions and detailed answers that will help you prepare effectively for the exam. By the end of this Docker containers book, you'll have learned how to efficiently deploy and manage container-based environments in production, and you will have the skills and knowledge you need to pass the DCA exam.

Who this book is for

This book is intended for people who want to learn about container technology and who are preparing for the Docker Certified Associate exam. This book was also written as a guide for Docker Enterprise products and serves as an introduction to Kubernetes' terminology and features.

Good Linux and Windows user knowledge is required, and some networking skills will help you to understand container networking and the use of load balancers and proxies to provide a full-featured Container as a Service environment.

The labs in this book are focused on Linux hosts because most current Docker Enterprise components are deployed on Linux operating systems. Windows hosts can be part of Docker Swarm and Kubernetes clusters, but control planes are deployed using Linux hosts.
