Mastering Docker Enterprise

By: Mark Panthofer

Overview of this book

While known mostly as the open source engine behind tens of millions of server nodes, Docker also offers commercially supported enterprise tooling known as the Docker Enterprise. This platform leverages the deep roots from Docker Engine - Community (formerly Docker CE) and Kubernetes, but adds support and tooling to efficiently operate a secure container platform at scale. With hundreds of enterprises on board, best practices and adoption patterns are emerging rapidly. These learning points can be used to inform adopters and help manage the enterprise transformation associated with enterprise container adoption. This book starts by explaining the case for Docker Enterprise, as well as its structure and reference architecture. From there, we progress through the PoC,pilot and production stages as a working model for adoption, evolving the platform’s design and configuration for each stage and using detailed application examples along the way to clarify and demonstrate important concepts.The book concludes with Docker’s impact on other emerging software technologies, such as Blockchain and Serverless computing. By the end of this book, you’ll have a better understanding of what it takes to get your enterprise up and running with Docker Enterprise and beyond.

Sample pilot planning and execution

To effectively illustrate the pilot planning tasks, we will continue to work through our sample pilot application. We'll start with a summary chart of decisions made for our pilot, where we tie them back to the key tasks described in the preceding RACI chart. From there, we will walk through the execution of the tasks along with a more detailed description of each of the decisions and how they are implemented in the Docker Enterprise environment.

For our sample pilot, we identified the objectives:

  • Set up a bare-metal Docker Enterprise install with CentOS 7.5—guided reference architecture
  • Design and implement a split DNS scheme for proper internal and external resolution
  • Secure the installation with NAT, firewalls, network isolation, and frontend load balancing
  • Use NFS on an isolated network for backing DTR and possibly application...
