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.

Docker Enterprise cluster plumbing

During the PoC phase, our only networking-related requirement was to have all of the nodes on the same network, and a network configuration that would allow for a free flow of traffic between the nodes. As we move forward to the pilot phase, we need to begin understanding Docker networks in more detail. We'll start by describing the networking Docker provides on a single engine node. Then, we will get into a discussion regarding networking in a clustered environment, such as a Swarm in Kubernetes.

Introduction to Docker single-node networking

While single-node networking may seem like an oxymoron, in the early days of Docker, many containers would run on a single node. Additionally...
