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 chapter covered the main Docker UCP features. We learned how to deploy a cluster with high availability and how to manage and deploy workloads using either UCP's web UI or the user bundle with the Docker and Kubernetes command line. We also introduced UCP's role-based access control, which helps us provide fine-grained access to cluster resources. We also took a look at the web UI and the main configurations available for managing Docker Enterprise's control plane.

We also learned about UCP's components and how to deploy and manage Docker Enterprise's control plane and user resources in production. Finally, we learned how to ensure platform availability by verifying a cluster's components' status and executing backups.

In the next chapter, we will learn how to publish a deployed application using Docker's integrated tools and features.
