Mastering Docker Enterprise

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 10: More on Kubernetes with Docker Enterprise

  1. Yes. However, in a production environment, you should designate the worker nodes as either Swarm or Kubernetes and not as mixed mode.
  2. Kubernetes itself does not have a network. You need to use a Container Networking Interface (CNI) from a provider and install it yourself. The Docker Enterprise Kubernetes platform automatically installs Calico as its default CNI provider. There is an installation parameter with Packer Enterprise Edition if you'd like to install a different CNI network plugin.
  3. Simply install Docker Desktop and enable Kubernetes. There is no need to install any other software to run the Kubernetes applications locally.
  4. A cluster IP service is only reachable from inside the cluster, whereas a NodePort service, such as a Swarm service with VIP layer 4 routing, can...
