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 9: Important Docker Enterprise Production Topics

  1. Health checks are a special bit of code provided by the container's creator. The health check code is periodically run by the Docker Engine inside the container and it reports the health status to the orchestrator. If the health check fails, the orchestrator removes the unhealthy container and creates a new one in its place. 
  2. Layer 7 dynamic routing, layer 4 simple port-based routing, and static host deployments. Layer 4 port-based routing and static host deployments are the most reliable and deterministic, making them the best choice for production implementations at this time. Layer 7 is very powerful, but has lots of moving parts and should be used with caution in production environments until you're very comfortable with its operation at scale.
  3. With a blue/green deployment, you are...
