Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

Preface

Kubernetes Design

Kubernetes focuses on the life cycle of containers, including configuration, scheduling, health checks, and scaling. With Kubernetes, it is possible to install various types of applications, including databases, content management systems, queue managers, load balancers, and web servers.

For instance, imagine you are working at a new online food delivery chain, named InstantPizza. You can deploy the backend of your mobile application in Kubernetes and make it scalable to customer demand and usage. Similarly, you can implement a message queue to communicate between the restaurants and customers, again in Kubernetes. To store past orders and receipts, you can deploy a database in Kubernetes with storage. Furthermore, you can use load balancers to implement Blue/Green or A/B Deployment for your application.

In this section, the design and architecture of Kubernetes are discussed to illustrate how it achieves scalability and reliability.
