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.

Chapter 3: Getting Started – Docker Enterprise Proof of Concept

  1. A four-node setup is highly recommended for PoCs to demonstrate UCP, DTR, and multiple worker nodes.
  2. The PoC application shortlist defines a backlog of possible applications to containerize during your PoC. It is generally a good idea to have at least three or four applications identified. That way, if you run into an obstacle with one application, you can just move on to the next. The point here is to get an application into a container and deploy it to the PoC cluster. As a rule of thumb, if it is taking longer than two days to containerize the PoC application, it is time to move on to the next application on your shortlist.
  3. Here are the four parts of a fully-qualified Docker image name:
    • A the registry URL (that is, dtr.mydomain.com/dev/web-app_build:v1.2)
    • Username or organization namespace (that...
