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.

Summary

This was the final chapter on our journey to becoming a Docker Certified Associate. We covered all the topics learned in previous chapters with some mock exam questions. As mentioned before, some of these questions are real questions posed in old exams.

The journey to becoming a Docker Certified Associate is not easy. We started this book from the very beginning, understanding why containers are so popular these days when we talk about microservices architectures. Then, we described how containers are executed using Docker Engine, integrating various isolation strategies to ensure security between container-embedded processes. As containers are based on images, we learned how to build and maintain them using Docker tools. We learned about different Docker objects and how to deploy applications using different networking methods, volumes, or security approaches. We learned how to deploy microservices applications, where every component is running containers. We learned the differences...
