For the benefit of containers, we can easily publish new programs by executing the latest image, and reduce the headache of environment setup. But, what about publishing the program on running containers? While managing a container natively, we have to stop the running containers prior to booting up new ones with the latest images and the same configurations. There are some simple and efficient methods for updating your program in the Kubernetes system. One is called rolling-update, which means Deployment can update its Pods without downtime to clients. The other method is called recreate, which just terminates all Pods then create a new set. We will demonstrate how these solutions are applied in this recipe.

Overview of this book
Kubernetes is an open source orchestration platform for managing containers in a cluster environment. This Learning Path introduces you to the world of containerization, in addition to providing you with an overview of Docker fundamentals. As you progress, you will be able to understand how Kubernetes works with containers. Starting with creating Kubernetes clusters and running applications with proper authentication and authorization, you'll learn how to create high-availability Kubernetes clusters on Amazon Web Services (AWS), and also learn how to use kubeconfig to manage different clusters. Whether it is learning about Docker containers and Docker Compose, or building a continuous delivery pipeline for your application, this Learning Path will equip you with all the right tools and techniques to get started with containerization.
By the end of this Learning Path, you will have gained hands-on experience of working with Docker containers and orchestrators, including SwarmKit and Kubernetes.
This Learning Path includes content from the following Packt products:
• Kubernetes Cookbook - Second Edition by Hideto Saito, Hui-Chuan Chloe Lee, and Ke-Jou Carol Hsu
• Learn Docker - Fundamentals of Docker 18.x by Gabriel N. Schenker
